Abstract
The utility model relates to a cylinder deactivating and oil saving device for an engine, which is used for solving the problem of fuel waste. The technical scheme is that: the oil saving device comprises an ECU of the engine, an ignition device and fuel injectors of various cylinders; a pressure release channel is arranged between a combustion chamber of each cylinder and an air inlet; the pressure release channel is provided with a pressure release solenoid valve; and a control coil of the pressure release solenoid valve is connected with the ECU of the engine. Compared with the conventional cylinder deactivating and oil saving device for the engine, the cylinder deactivating and oil saving device can control four cylinders to alternately deactivate, not only can make the engine stably operate, but also cannot cause compressor pump air power loss.
Description
Technical field
The utility model relates to a kind of engine fuel-saving apparatus, and particularly the four cylinder four-stroke internal-combustion engine reduces discharging the device of mode fuel saving by cylinder deactivation under idling or low loading condition, belongs to technical field of engines.
Background technique
Automobile becomes the main traffic tool of people's trip just gradually, and the continuous increase of automobile pollution has aggravated energy crisis, makes the energy-saving and cost-reducing of automobile seem important further.Cylinder deactivation (the part cylinder is quit work) is a kind of effective power-economizing method that present people adopt, for the four cylinder four-stroke motor, existing power-economizing method is to stop three cylinders or the long-time cylinder deactivation of single cylinder, and stop for a long time a cylinder will inevitably cause engine running not steadily, disequilibrium, make automotive body vibration aggravation, noise increases, and reduces taking advantage of of automobile and drives travelling comfort.In addition, when cylinder quit work, piston was done passive to-and-fro motion, and the compression gas in the jar can cause the loss of engine compresses pumping work rate, and engine efficiency is reduced.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can make the running of motor held stationary and not produce the motor cylinder-down oil saver of compressor pump qigong rate loss.
Problem described in the utility model realizes with following technical proposals:
A kind of motor cylinder-down oil saver, ECU, ignition mechanism, each cylinder oil sprayer of comprising motor in the formation, be provided with pressure release passage between each cylinder chamber and intake duct, described pressure release passage is provided with the pressure release solenoid valve, the ECU of the control coil sending and receiving motivation of described pressure release solenoid valve.
The above-mentioned motor cylinder-down oil saver of stating, described pressure release passage one end leads to the firing chamber, and an end is communicated with intake duct.
Above-mentioned motor cylinder-down oil saver, described motor are the four cylinder four-stroke motor.
The utility model all is provided with pressure release passage and pressure release solenoid valve between the firing chamber of each cylinder of motor and intake duct, by the break-make of ECU by pressure release electromagnetic valve pressure release passage, when motor is in idling or low load condition, ECU makes four cylinders according to ignition order cylinder deactivation in turn successively, each cylinder is during cylinder deactivation, its oil sprayer stops oil spout, spark plug and stops igniting, and fuel saving has been avoided the unbalanced phenomena of four cylinders.Its pressure release solenoid valve conduction makes the firing chamber be communicated with intake duct by pressure release passage simultaneously, prevents to produce the loss of compressor pump qigong rate.Compare with the available engine cylinder-down oil saver, the utility model can not only make the running of motor held stationary, and can not produce the loss of compressor pump qigong rate.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is the cylinder sectional view.
Each label is among the figure: 1, bent axle; 2, connecting rod; 3, wrist pin; 4, piston; 5, firing chamber; 6, spark plug; 7, air outlet flue; 8, cylinder head; 9, valve spring; 10, exhaust cam shaft; 11, admission cam shaft; 12, oil sprayer; 13, intake duct; 14, pressure release solenoid valve; 15, pressure release passage; 16, cylinder block; 17, cylinder sleeve; 18, connecting rod bearing shell; 19, connecting-rod bolts; 20, distributor; 21, spark coil; ECU, electronic control unit.
Embodiment
The working state of four cylinder four-stroke internal-combustion engine: when normal working of engine, four cylinders are according to the work of doing work successively of 1,3,4,2 ignition order, under this igniting strategy, ignition-powering is once in the time in two weeks of bent axle revolution (720 degree) for each cylinder.Under normal load condition, this working state of motor can satisfy the automobile need of work, do not have too many idle work, but when engine loading less or under the situation of idling, motor does not need too many power output, thereby can reach the purpose of fuel-economizing by single cylinder cylinder deactivation at intermittence.
Referring to Fig. 1, the utility model comprises ECU, ignition mechanism, oil sprayer 12 and pressure release solenoid valve 14, oil sprayer 12 and pressure release solenoid valve 14 all have four, four cylinders of the corresponding motor of difference, and ignition mechanism comprises four spark plugs 6, distributor 20 and spark coil 21.Whether whether ECU be in the decision of cylinder deactivation state at its time of ignition output firing pulse according to certain cylinder.
Referring to Fig. 2, pressure release solenoid valve 14 is installed on the cylinder head 8, and when normal working of engine, pressure release solenoid valve 14 is in closed condition, and the air pressure in the gas combustion chamber 5 can not revealed, and cylinder keeps normal acting; When some cylinders are realized cylinder deactivation, when promptly stopping the oil spout igniting, steam-cylinder piston 4 is under the drive of bent axle 1, move reciprocatingly, in the time of as compression and working stroke, pressure release solenoid valve 14 is opened, and then the air pressure in the cylinder chamber 5 will make cylinder internal communicate with intake duct 13 by pressure release passage 15, like this in-cylinder pressure will with the air-distributor pressure balance, make that the pump atmosphere pressure losses drops to minimum in the cylinder.
The cylinder deactivation of motor depends on the working condition of motor, when engine operating condition enters cylinder deactivation arteries and veins spectrum operating range, ECU will control pressure release solenoid valve 14 on the one hand and open and close in good time, on the other hand, ECU also will control the in good time cylinder deactivation of each cylinder, promptly stop oil spout igniting in good time, solve and stop the running imbalance problem that a cylinder job brings separately.Be by the control of ECU arteries and veins spectrum specifically, make four cylinders replace cylinder deactivation, guarantee the transient equiliblium of motor.Control arteries and veins spectrum is set four the work cycle cylinder deactivations in the every interval of each cylinder of motor once, and four cylinders have also been realized dynamic running balance according to 1,3,4,2 sequence alternate cylinder deactivation in fuel-economizing.
Table 1 is an example of control arteries and veins spectrum, abscissa is engine speed (n), y coordinate is engine load (%), arteries and veins spectrum controlling value is that pressure release solenoid valve 14 opens and closes signal, as seen from Table 1, under the control of this arteries and veins spectrum, under middle and slow speed of revolution and low-load, pressure release solenoid valve 14 is opened (controlling value is 0), realizes cylinder deactivation.
Table 1
Table 2 is four cylinders orders of cylinder deactivation successively, and the cylinder deactivation process of each cylinder by ECU control oil sprayer 12, can not enter in the cylinder deactivation cylinder fuel all from exhaust stroke.In compression stroke, pressure release solenoid valve 14 is opened, and makes in the cylinder to be interlinked to the outside with cylinder, has reduced the resistance that piston 4 makes progress.
