Abstract
A motor vehicle includes a diesel internal combustion engine 1 driving an electric generator 2 contolled by an electronic control unit 7, and at least one electrical power storage means to store energy created by the generator, eg a battery 4. The electronic control means is operable to periodically apply a load to the internal combustion engine so that it provides sufficient heat to cause regeneration of a particulate trap 5 present in the vehicle's exhaust system 8. Preferably the motor vehicle is provided with a secondary source of power, eg one or more electric motors 3, such as in a hybrid motor vehicle. An internal clock located within the electronic control unit is used to determine when the engine has been operated for sufficient time to require regeneration of the particulate trap. When regeneration is required a load is applied to the engine by causing the electric generator to rapidly charge the electrical power storage means. If one or more electric motors are present then a negative current may be applied to them, to produce a braking effect that increases the load on the engine.
Description
A Motor Vehicle
This invention relates to a motor vehicle and in particular to a motor vehicle having more than one source of motive power such as a hybrid motor vehicle.
It is well known to provide a motor vehicle with an internal combustion engine to provide a first or primary source of motive power and one or more electric motors to provide a secondary source of motive power.
The internal combustion engine is normally arranged to drive an electric generator which is used to either charge a battery pack or directly supply electrical power to the or each electric motor.
It is commonly the case that a diesel internal combustion engine is used for such hybrid purposes due to the relatively good fuel economy obtainable from such an engine under part load conditions and the superior emission characteristics of such an engine.
It is however a problem with current diesel hybrid motor vehicles that the diesel engine must be fitted with a particulate trap that needs to be regularly regenerated.
To regenerate such a particulate trap it must be heated to a high temperature for a predetermined period of time to burn off the collected carbon cleanly. If the regeneration of the particulate trap is not carried out at sufficiently frequent periods the excess material can begin to combust producing excessive emission by-products.
With a normal motor vehicle regeneration of the particulate trap is not a serious problem as the vehicle normally experiences a use cycle that inclues a regular period of high load running to provide sufficient heat to regenerate the collected particulates. However, with a hybrid vehicle the diesel engine may never experience such periods of high load running as such a level of output power is rarely required for urban operation.
It has been proposed for such hybrid vehicles to provide an electric heater that can be switched on at pre-determined periods to regenerate the particulate trap but such heaters require a considerable electric current to generate sufficient heat.
It is an object of this invention to provide a means for regenerating the particulate trap of a diesel engine motor vehicle in a more efficient manner.
According to the invention there is provided a motor vehicle having a diesel internal combustion driving an electric generator, the engine having an exhaust system to guide exhaust gases away from the engine, the exhaust system including a particulate trap to reduce the emission of particulates of combustion from the engine, at least one electrical power storage means to store electrical energy generated by the electric generator and an electronic control means to control the operation of the electric generator wherein the electronic control means is operable to periodically apply a large load to the internal combustion engine to cause the particulate trap to be regenerated by the heat generated by the engine.
The electric generator may be connected to at least one electric motor forming a secondary source of motive power for the motor vehicle.
The electronic control unit may be operable to energise the or each electric motor to provide a resistance to motion so as to apply a large load to the internal combustion engine.
The electronic control unit may be operable to charge the electrical power storage means at a high rate so as to apply a large load to the internal combustion engine.
The electronic control unit may be operable to regenerate the particulate trap dependant upon the number of hours that the diesel engine has been operated for.
The electronic control unit is operable to regenerate the particulate trap when the normal load upon the diesel engine is sensed to be in a steady state.
The invention will now be described by way of example with reference to the accompanying drawing of which:
Fig. l is a schematic representation of part of a motor vehicle according to a first embodiment of the invention; and
Fig. 2 is a schematic representation of part of a motor vehicle according to a second embodiment of the invention.
Fig. 3 is a schematic representation of part of a motor vehicle according to a third embodiment of the invention.
With reference to Fig. 1 there is shown a diesel internal combustion engine 1 driving an electric generator 2. An exhaust system 8 is arranged to transfer exhaust gases away from the engine 1.
A particulate trap 5 is formed as part of the exhaust system 8 and is arranged to collect particulate products of combustion generated by the engine 1.
The electric generator 2 is connected to an electrical power storage means in the form of a battery 4 and to an electric motor 3 associated with two or more-of the road wheels 6 of the motor vehicle. The flow of electrical power from the generator 2 to the battery 4 and the motor 3 is controlled by an electronic control unit 7.
The electronic control unit 7 receives a signal of driver demand from a sensor associated with an accelerator pedal 9 and a signal indicative of vehicle speed from a speed sensor 10 associated with the road wheel 6.
During normal use the engine 1 drives the generator 2 to produce electrical power to recharge the battery 4 and or drive the electric motor 3 in response to the signal received by the electronic control unit 7 from the accelerator pedal 9.
An internal clock located within the electronic control unit 7 is used to determine when the engine has been operated for sufficient time to require regeneration of the particulate trap 5. When the requisite period of time has elapsed the electronic control unit 7 applies a large load to the engine by causing the electric generator 2 to rapidly charge the battery 4. The large load applied to the engine 1 causes the temperature of the exhaust gasses flowing from the engine to increase to a temperature sufficient to regenerate the particulate material caught within the particulate trap 5.
To assist with the loading of the engine 1 one of the electric motors may have a negative current applied to it to produce a braking effect upon the vehicle that has to be compensated for by the remaining electric motor 3. This will cause the electric motor 3 driving the vehicle forwardly to require more electrical power than normally would be the case.
With particular reference to Fig. 2 there is shown a diesel internal combustion engine 11 driving an electric generator 12. An exhaust system 18 is arranged to transfer exhaust gases away from the engine 11.
A particulate trap 15 is formed as part of the exhaust system 18 and is arranged to collect particulate products of combustion generated by the engine 11.
The electric generator 12 is connected to an electrical power storage means in the form of a battery 14 and to an electric motor 13 driving one or more of the road wheels 16 of the motor vehicle. The flow of electrical power from the generator 12 to the battery 14 and the motor 13 is controlled by an electronic control unit 70.
The electronic control unit 70 receives a signal of driver demand from a sensor associated with an accelerator pedal 19 and a signal indicative of vehicle speed from a speed sensor 20 associated with the road wheel 16.
The output from the engine 11 is connected directly to an output shaft of the motor 12 which is connected to the or each road wheel 16. In practice a gearbox is interposed between the motor 13 and the road wheels 16.
During normal use the engine 11 drives the road wheels 16 directly through the output shaft of the electric motor 13 and the electric generator 12 produces sufficient electrical power to recharge the battery 14.
When low emission running is required the electric motor 13 is switched on and the engine 11 is uncoupled from the electric motor 13 and switched off.
The electronic control unit 70 monitors the operating conditions and duty cycle that the engine 11 is subjected to a calculates when the particulate trap 15 will require regeneration.
When the requisite conditions exist the electronic control unit 70 applies a large load to the engine 11 by applying a negative current to the electric motor 13 causing it to produce a braking effect upon the vehicle that has to be compensated for by the engine 11.
The large load applied to the engine 11 causes the temperature of the exhaust gases flowing from the engine to increase to a temperature sufficient to regenerate the particulate material caught within the particulate trap 15.
After a pre-determined period of time the electronic control unit 70 removes the load from the engine 11 thereby allowing it to resume normal operation.
To ensure that the performance of the motor vehicle is not adversely effected by this regeneration the electronic control unit 70 only allows regeneration to take place when the signal from the speed sensor 20 indicates that the motor vehicle is travelling in a steady state and not accelerating.
With particular reference to Fig. 3 there is shown a diesel internal combustion engine 111 driving a gearbox 50. An exhaust system 118 is arranged to transfer exhaust gases away from the engine 111.
A particulate trap 115 is formed as part of the exhaust system 118 and is arranged to collect particulate products of combustion generated by the engine 111.
An electric generator (not shown) is driven by the engine 111 and is connected to an electrical power storage means in the form of a battery 114 and to an electric motor 113 driveably connected by means of a transmission belt or chain 51 to an output shaft 52 of the gearbox 50. The output shaft 52 being arranged to supply drive to one or more of the road wheels 116 of the motor vehicle.
The flow of electrical power from the electric generator to the battery 114 and to the motor 113 is controlled by an electronic control unit 170.
The electronic control unit 170 receives a signal of driver demand from a sensor associated with an accelerator pedal 119 and a signal indicative of vehicle speed from a speed sensor 20 associated with the road wheel 116.
During normal use the engine 111 drives the road wheels 116 through the output shaft of the gearbox 50 and the electric generator produces sufficient electrical power to recharge the battery 114.
When low emission running is required the electric motor 113 is switched on and the engine 111 is uncoupled from the gearbox 50 by means of a clutch (not shown).
The electronic control unit 170 monitors the operating conditions and duty cycle that the engine 111 is subjected to a calculates when the particulate trap 115 will require regeneration.
When the requisite conditions exist the electronic control unit 170 applies a large load to the engine 111 by applying a negative current to the electric motor 113 causing it to produce a braking effect upon the vehicle that has to be compensated for by the engine 111.
The large load applied to the engine 111 causes the temperature of the exhaust gases flowing-from the engine to increase to a temperature sufficient to regenerate the particulate material caught within the particulate trap 115.
After a pre-determined period of time the electronic control unit 170 removes the load from the engine 111 thereby allowing it to resume normal operation.
To ensure that the performance of the motor vehicle is not adversely effected by this regeneration the electronic control unit 170 only allows regeneration to take place when the signal from the speed sensor 120 indicates that the motor vehicle is travelling in a steady state and not accelerating.
