Definitions
- the invention relates to a method for reducing the fuel consumption of internal combustion engines.
- the invention also relates to a suitable device for carrying out the method according to the invention.
- a certain amount of water is fed into the combustion chamber of the engine via an air intake inlet of the engine.
- a parameter is determined which is a measure of the amount of fuel currently required by the engine, and the amount of water is then determined as a function of this parameter. It is preferably ensured that a certain quantitative ratio of water and fuel is always maintained.
- the water which can be conventional tap water, for example, increases the volume of energy generated during the combustion, as a result of which a certain amount of fuel is saved during the combustion.
- the amount of fuel saved corresponds approximately to the amount of water supplied, i.e. H. a certain amount of fuel is simply replaced by water. As a result of the reduction in fuel, pollutant emissions are also reduced.
- a corresponding device for reducing fuel consumption requires, on the one hand, a measuring device to determine the parameter which is to serve as a measure of the amount of fuel currently required by the engine.
- the device must have means for supplying water into the combustion chamber via an air intake inlet of the engine.
- a metering device for metering the amount of water and a control unit are required, which controls the metering device as a function of the determined parameter, i. H. ultimately determines the amount of water.
- the device With the method according to the invention and the device according to the invention, it is possible to reduce the current consumption of any fuel engine, regardless of the year of construction, the state of the art and the field of application.
- the device works independently of the actual engine control. This is particularly advantageous in that a retrofit of existing motors is also relatively easy with such a device. It is only necessary to have access to the water intake at an air intake to create and at any suitable point to record a parameter which corresponds to the currently requested amount of fuel, ie with the current consumption of the engine. Otherwise no further intervention in the engine or the engine control is necessary.
- the parameter for determining the amount of fuel currently required by the engine can be a flow rate in a fuel feed line of the engine, which is measured using a conventional flow meter which is built into the fuel feed line. If the engine has fuel recirculation, the flow rate should also be measured here using a flow meter. The current consumption, which serves as a parameter for determining the amount of water, is then the difference from the measured flow rates.
- Another preferred alternative is to determine the speed of the motor as a parameter for determining the amount of water. It makes sense to measure the speed of the engine using the frequency of an alternator coupled to the engine. This method is particularly simple to use in trucks which generally have a so-called “W output” on the alternator anyway, at which the alternator frequency can be measured in a simple manner. The measured values can then be integrated in the control unit or in one If necessary, flow meters are installed in the fuel supply line and in the fuel return line.
- the water content can be optimized by measuring pollutant emissions. H. This value is used to determine the relationship between the amount of water and the amount of fuel. This ratio of fuel to water is then kept constant by the controller based on the measured flow rate.
- the amount of water can also be regulated by returning an actual value and comparing it with a target value.
- the control system has proven to be sufficient and is simpler and cheaper than a control system.
- a nozzle is installed in an air intake of the engine, with the aid of which the water is supplied in the air intake, ie. H. is injected.
- the aid of which the water is supplied in the air intake ie. H. is injected.
- Air intake ports are arranged so that due to the different pressure conditions, more water is not supplied to one air intake port than to another air intake port.
- a particularly simple method of metering the amount of water is to use a controllable pump unit which is controlled accordingly by the control.
- the use of a peristaltic pump, as is usually also used in the medical field, is particularly suitable here. With such a hose pump, very precise metering is possible by means of a motor which is controlled by the control device.
- the peristaltic pumps are also quite low-maintenance. In normal operation, a hose inside the hose pump only needs to be replaced about once a year.
- a good alternative to the peristaltic pump is provided, for example, by vibration pumps or vibration diaphragm pumps, with which a relatively precise metering is also possible and which are almost maintenance-free.
- the water can be taken from a separate tank, which can be easily retrofitted in most vehicles.
- a separate tank which can be easily retrofitted in most vehicles.
- the spirit burns easily when injected into the combustion chamber and has no negative impact.
- the tank is preferably equipped with a level indicator that signals the user when it is necessary to refuel with water.
- the device particularly preferably has a heating device in order to preheat the water before it is introduced into the engine.
- the waste heat from the engine can also be used by e.g. B.
- the water supply line is guided past a correspondingly warm part of the engine, preferably using a heat exchanger.
- a heated water tank can also be used, the water tank in particular also being able to be positioned at a suitable point in the engine compartment where a higher temperature prevails anyway.
- the control device can, for example, essentially consist of a single-board computer with a correspondingly programmed microcontroller.
- This controller preferably first ensures that, depending on the parameter determined, the pump unit is switched on above or below a first predetermined limit value and the pump unit is accordingly switched off again above or below a second limit value. For example, when determining the engine speed as the decisive parameter from a certain speed range, the pump is switched on and, as soon as the speed range is above the second limit value, the pump is switched off again.
- the control unit controls the amount of water depending on the measured parameter.
- the control is preferably linear, i. H. the amount of water is also increased linearly as the fuel requirement or parameter increases.
- a minimum parameter is first determined when the engine is idling.
- a maximum parameter value is then determined for a maximum quantity of fuel supplied. This is done, for example, simply by resetting the control unit at idle and at full throttle. This setting of the limit values can also be repeated at any time by the user himself.
- the proportion of the amount of water, based on the amount of fuel, for. B. a ratio to be kept constant, is set before the first start-up of the device, for example with the aid of a potentiometer on the controller. It is also possible to preset the relationship between the amount of water and the amount of fuel by using a suitable hose diameter in at least one line section of the supply line for the water. When using a peristaltic pump, it is advisable to use the hose section within the pump, which is to be changed regularly anyway.
- the ratio of the amount of water to the amount of fuel is selected depending on the particular engine type and / or the age of the engine.
- the proportion of the water quantity is preferably between 7 and 25%, based on the sum of water and fuel quantity, ie the water proportion is 7 to 25% of the fuel required without water supply.
- the water content based on the fuel quantity should preferably be set again after a certain operating time after the engine has been started for the first time with the water supply according to the invention.
- the ratio between the amount of water and the amount of fuel can then be reduced since the engine is cleaner due to the water supply that has already taken place, and as a rule this already improves the efficiency of the combustion.
- this changeover usually takes approximately 100 hours of operation.
- this change can be made very simply, for example, by exchanging the tube in the peristaltic pump for a tube with a smaller diameter.
- the setting of the relationship between the amount of water and the amount of fuel can also be optimized by, for example - as already mentioned above - measuring the pollutant emissions at the exhaust of the engine and using this parameter for adjustment or readjustment.
- the ratio is always optimally adjusted and readjustment after a certain number of operating hours is then no longer necessary. It is clear, however, that this process is more complex to control.
- the device according to the invention and the method according to the invention can be applied to any motor-driven vehicles and / or motor-driven machines which have a corresponding internal combustion engine.
- a decisive advantage is the complete independence from an existing engine control and the minimal intervention in one standing engine control and the minimal intervention when retrofitting an engine.
- FIG. 1 shows a schematic illustration of a device according to the invention in accordance with a first exemplary embodiment
- FIG. 2 shows a schematic illustration of a device according to the invention in accordance with a second exemplary embodiment
- FIG. 3 shows a top view of a control unit
- Figure 4 is a plan view of a user interface for the control unit.
- Figures 1 and 2 each show the device according to the invention when used on a clocked internal combustion engine 1, for example a diesel or gasoline engine in a motor vehicle.
- a clocked internal combustion engine for example a diesel or gasoline engine in a motor vehicle.
- This engine 1 has an air intake 3 on each cylinder, here a conventional air intake 3.
- the engine 1 is connected to an injection system 18, which injects the fuel into the engine 1.
- This injection system 18 is connected to a tank (not shown) via a fuel feed line 16.
- This can be, for example, a direct injection system. However, it can also be a facility in which the Fuel, which is common in older engines with a so-called downdraft carburetor, also gets into the combustion chamber via the air intake.
- the exhaust gases from engine 1 are expelled through an exhaust outlet 28 or exhaust.
- a nozzle 4 is installed in the side wall of the air intake 3.
- the nozzles 4 are each mounted at the same height as the air intake ports in order to avoid pressure differences at the individual nozzles 4.
- water 2 is supplied via a line 8.
- This water 2 is kept in a water tank 10. There it is removed via a feed line 9, here a riser pipe, by means of a pump unit 5 and transported into the feed line 8.
- the water 2 is normal tap water which is filled into the water tank 10 via an opening 29, for example when the vehicle is being refueled. Since it is normal tap water 2, in the present exemplary embodiment there is a filter 11 in the feed line 9 from the water tank 10 to the pump unit 5. If filtered and, for example, distilled water is already used, this filter can also be dispensed with.
- the pump unit 5 in the present case consists of a peristaltic pump 6, which is operated with an electric motor 7.
- This electric motor 7 is controlled by a control unit 20.
- the exact amount of water that is currently introduced into the air intake 3 is therefore metered via the control unit 20 by means of the pump unit 5.
- the electric motor 7 is controlled via the output 24 of the control unit 20.
- the control unit 20 In order to calculate the amount of water required, the control unit 20 first determines a parameter which corresponds to the current fuel consumption of the engine 1. For this purpose, in the exemplary embodiment according to FIG. 1, a so-called W output 15 is coupled to the motor 1 Alternator 14 tapped the frequency and given to a measurement input 25 of the control unit 20. This frequency is a measure of the current speed of the engine 1 and thus also of the current fuel consumption.
- the control unit is also connected via the output 26 to a user interface 30 which, in addition to a reset button 32 for calibrating the device, has an on / off switch 31 with which the entire device can optionally be switched on or off.
- the engine 1 functions as if the device according to the invention were not installed in the motor vehicle.
- this user interface 30 has a display block 34 in order to display various parameters for the user.
- the display block 34 comprises, on the one hand, a row of light-emitting diodes 33 with which the current consumption is displayed in percent based on the consumption without the addition of water. In other words, the water content that replaces the fuel content is essentially displayed.
- This LED display can also be used, for example, to adjust the control unit 20 with the aid of a potentiometer (not shown) and thus to determine the optimum setting. There are also additional LEDs in the display unit.
- One of these LEDs indicates the ready state of the device, another the activity of the pump unit 5, a third the activity of a heater 12 for preheating the water 2 and a fourth one is there to indicate the water level in the water tank 10.
- the water level is measured via a water level measuring device 13 at the input 22 of the control unit 20.
- the heater 12 is also located on the water tank 10 and is controlled by the control device 20 via the outlet 23.
- the user interface 30 is usually in the area of the dashboard or the center console. It can also be retrofitted there.
- the other components, such as the water tank and the pump as well as the control, can be connected to anywhere in the vehicle, for example in free areas in the engine compartment or in the trunk.
- the housing of the control unit is shown in Figure 3. It is a relatively small housing in which there is only a single-board computer with a microcontroller with eight analog / digital converter inputs in the present exemplary embodiment. Two socket strips with 16 digital connections each can be programmed as either inputs or outputs. Due to the programmable microcontroller in the control unit 20, it is possible at any time to change the control with suitable software and to adapt or update it to specific circumstances.
- the housing itself only has the required six inputs or outputs. Otherwise it is completely closed and is only opened for maintenance purposes.
- the housing of the control unit is not larger than 8 x 5 x 3.5 cm and is therefore easy to accommodate anywhere in the vehicle. The largest construction volume of the entire device takes up the water tank 10.
- the control unit 20 is connected via a supply voltage input 27 to a motor vehicle battery 19 which is fed by the alternator 14.
- a motor vehicle battery 19 which is fed by the alternator 14.
- the battery which is already in the vehicle, is used. Alternatively, a separate battery can also be used.
- the measuring devices, the user interface 30, the heater 12 of the water tank 10 and the electric motor 7 are also supplied with the required energy via the control unit 20.
- the parameter range ie a window
- the control unit 20 controls the pump unit 5 such that it is linear with the increasing measured parameter value also increases the amount of water. In this way, for example, a set ratio of the amount of water to the amount of fuel is kept approximately constant. It is also possible to use other control courses within the window, e.g. B. provide an exponential or square course.
- a rough setting is first made via the choice of the diameter of the hose within the hose pump 6.
- a fine setting is then made via a setting by means of the potentiometer (not shown) in the control unit 20.
- control unit 20 controls the pump unit 5 within a speed range of 1,500 revolutions / min. and 4,500 revolutions / min. No water is added outside this speed range.
- the motor 1 then functions as if the device were not present at all.
- FIG. 1 clearly shows, the intervention in the already existing motor or the motor control is minimal. It is only necessary to tap the frequency at the already existing W output 15 of the alternator 14 and to install a nozzle 4 in the air intake 3.
- the device according to the invention then works completely independently of the other engine control.
- FIG. 1 a system is shown, which is preferably intended for installation in trucks, since trucks usually have the W output 15 mentioned on the alternator. Unfortunately, such a W output 15 is generally not available on the alternator 14 in cars. As a simple alternative, it therefore makes sense in cars to measure the flow rate in the fuel supply line 16.
- FIG. 2 a device according to FIG. 2 can also be installed in a truck. The structure of the entire device according to FIG. 2 essentially corresponds to the structure according to FIG. 1. The only difference is that this device has an additional flow meter 17 in the fuel line 16, which is connected to the measurement input 25 of the control unit 20. If it is a motor system that has a gasoline recirculation, a flow meter is preferably also used there and the difference between the two flow meters in the gasoline supply line 17 and in the recirculation is used as a parameter for calculating the fuel consumption.
- an existing vehicle can be retrofitted at any time without any problems.
- fuel savings of at least 15 to 20% were achieved in various test vehicles, for example a 1999 Passat Diesel and a BMW 19 gasoline vehicle, as well as in various types of trucks and construction machines.
- the emissions have been reduced accordingly.
- the injection of water into the air intake also led to a cleaning of the combustion chamber and thus to an improvement in the efficiency of the combustion, which had an additional positive effect.
