The fuel saving device can allow all the air cylinders or a part of the six air cylinders to work according to the load of the engine; under the premise of ensuring stable running of the engine, the fuel can be saved, the operation benefits can be increased; and the fuel saving device can be applied to a cargo diesel automobile during running at a high speed.
Description
Technical field
The invention belongs to diesel automobile engine technical field, particularly hexa-cylinder diesel automobile engine fuel-saving apparatus.
Background technology
The work process of Diesel engine is as petrol engine, and each cycle of operation also experiences air inlet, compression, work done, four strokes of aerofluxus.But owing to the fuel of use for diesel engine is diesel oil, its ratio of viscosities gasoline is big, is difficult to evaporation, and its autoignition temperature is low compared with gasoline, and therefore formation and the sparking mode of combustion mixture are all different from gasoline engine.
What diesel engine sucked in suction stroke is pure air.In compression travel close to when ending, oil pressure is brought up to more than 10MPa through injection pump by diesel oil, and diesel oil is transported to each cylinder fuel oil room, mix with the high temperature air after compression within a very short time, form combustion mixture by high-pressure oil pump.Owing to diesel engine compression ratio is high (generally 16-22), so cylinder inner air pressure is up to 3.5-4.5MPa when compression ends, temperature is up to 750-1000K (and the mixture pressure that gasoline engine is at this moment can be for 0.6-1.2MPa simultaneously, temperature reaches 600-700K), substantially exceed the autoignition temperature of diesel oil.Therefore diesel oil is after spraying into cylinder, gets angry burning with air after mixing within a very short time the most voluntarily.Air pressure in cylinder rises to 6-9MPa rapidly, and temperature is also raised to 2000-2500K.Under gases at high pressure promote, piston moves downward and band dynamic crankshaft rotates and work done, and waste gas is equally in exhaustor enters air.
One cycle of operation of single cylinder four-stroke engine (bent axle rotates two weeks) the external work done of only one of which stroke, necessarily causes internal combustion engine and work mechanism to rotate lack of homogeneity.In order to improve smoothness of operation, improve balance, automobile engine typically uses the combination of multiple single cylinder engine.Two or more cylinders of all employings, and the piston connecting rod unit of each cylinder shares the internal combustion engine of a bent axle and is referred to as multi-cylinder engine.Diesel car for transport mostly is 6 Cylinder engines.For straight-six engine, between each cylinder, sequencing mostly uses 1-5-3-6-2-4.
Under normal circumstances, six cylinders of six cylinder engine are operated according to the order of 1-5-3-6-2-4, and to ensure the service behaviour of electromotor, this, when Engine full load works, more needs.And, in the traditional consciousness of people, once partial cylinders does not works, and just belongs to electromotor and breaks down.But, due to automobile engine, particularly goods vehicle electromotor, its workload is often change, such as through often there is situation when empty wagons returns or drives to highway from common road after goods delivers to destination.If now six cylinders continue to work, certainly will occur that engine power is superfluous, fuel oil exorbitant expenditure, thus increase the practical problem of cost of transportation.In order to solve cost of transportation problem, driver through sliding frequently with neutral gear, the way such as coasting with engine off, this brings hidden danger to driving safety.
Summary of the invention
Being to provide a kind of hexa-cylinder diesel automobile engine fuel-saving apparatus, this device can select cylinder all to work or part work according to the load condition of electromotor the mesh of the present invention, is ensureing that electromotor operates steadily under ground premise, and saving fuel oil improves operating benefit.
The present invention certainly technical problem is adopted the technical scheme that: hexa-cylinder diesel automobile engine fuel-saving apparatus, including injection pump and connect injection pump to the pipeline road of each combustion chamber of air cylinder, it is characterized in that, being serially connected with electromagnetic valve corresponding with oil circuit in the pipeline road of injection pump to the first cylinder and/or the 6th cylinder combustor, the control knob of described electromagnetic valve is arranged on the position that driver easily manipulates.
The invention has the beneficial effects as follows:
Owing to being serially connected with electromagnetic valve corresponding with oil circuit in the pipeline road of injection pump to combustor, by controlling corresponding electromagnetic valve, thus whether control the work of this cylinder, thus the work of achievement unit sub-cylinder artificially, the fuel oil consumption making electromotor adapts with workload, improve the economy that electromotor runs, reduce operation cost.
Owing to applying on six cylinder engine, the fuel oil of the first cylinder and/or the 6th cylinder is controlled, the operation stability of electromotor is had substantially no effect at high speed transport condition, and fuel path controlled cylinder other side, the most do not change in terms of intake and exhaust, lubrication etc., so not interfering with the life-span of electromotor.
Using during the general high-speed cruising in the car of the present invention, during low speed, electromotor is likely to occur operation shakiness.Can be switched at any time by electromagnetic valve.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention；
In figure: 1 first cylinder, 2 second cylinders, 3 the 3rd cylinders, 4 the 4th cylinders, 5 the 5th cylinders, 6 the 6th cylinders, 7 injection pumps；11 first cylinder solenoid valves, 12 first cylinder solenoid valve switches, 61 the 6th cylinder solenoid valves, 62 the 6th cylinder solenoid valve switches.
Detailed description of the invention
Below by embodiment, the technical program is further described.
Embodiment 1:
Hexa-cylinder diesel automobile engine fuel-saving apparatus, including a shared injection pump 7, six independent pipeline roads of connection injection pump to each combustion chamber of air cylinder.1 first cylinder, 2 second cylinders, 3 the 3rd cylinders, 4 the 4th cylinders, 5 the 5th cylinders, 6 the 6th cylinders.
Being serially connected with the first cylinder solenoid valve 11 in the pipeline road of injection pump to the first cylinder 1 combustor, this electromagnetic valve is controlled by the first cylinder solenoid valve switch 12 being arranged in driver's cabin.In like manner, being serially connected with the 6th cylinder solenoid valve 61 in the pipeline road of injection pump to the 6th cylinder 6 combustor, this electromagnetic valve is controlled by the 6th cylinder solenoid valve switch 62 being arranged in driver's cabin.
Can be switched at any time by electromagnetic valve during high-speed cruising in the car.Realize single cylinder or two cylinder oil-break misfires.The control knob of described electromagnetic valve is arranged on the position that driver easily manipulates, and is preferably located on the operating knob panel of driver's cabin.
Owing to being serially connected with electromagnetic valve corresponding with oil circuit in the pipeline road of injection pump to combustor, by controlling corresponding electromagnetic valve, thus whether control the work of this cylinder, thus the work of achievement unit sub-cylinder artificially, the fuel oil consumption making electromotor adapts with workload, improve the economy that electromotor runs, reduce operation cost.
Owing to applying on six cylinder engine, the fuel oil of the first cylinder and/or the 6th cylinder is controlled, the operation stability of electromotor is had substantially no effect at high speed transport condition, and fuel path controlled cylinder other side, the most do not change in terms of intake and exhaust, lubrication etc., so not interfering with the life-span of electromotor.
This device is particularly suitable for when shipping diesel car travels under high speed state using.This device was once applied on the shipping diesel car in Shanghai to Hangzhou, used the heavy truck that loading capacity is identical, and result of the test is, under identical mileage, identical road conditions, when using the carload of this device, fuel-economizing reaches 17%, and time unloaded, fuel-economizing reaches 33%.There is obvious oil-saving effect.
