Description
Technical field
The present invention relates to a kind of automobile-used electric injection system, particularly a kind of motorcycle engine electric spray system.
Background technique
Electronic fuel injection engine is to adopt electric control device to replace the fuel feeding process that traditional mechanical system (as Carburetor) is controlled motor.Electric injection system is by the oil spout oil circuit, and sensor groups and electronic control unit (ECU) three parts are formed.The oil spout oil circuit is by electric oil pump, fuel filter, and oil pressure regulator, compositions such as oil sprayer, the electric injection system of motorcycle, oil sprayer is installed on the engine throttle.During work, electronic control unit is according to the temperature of the various sensors of motor with motor, air fuel ratio, the throttle situation, the rotating speed of motor, load, crank position, signals such as traveling state of vehicle input electric control device, electric control device is according to these signal parameters, calculate and the control needed fuel injection quantity of each cylinder of motor and the oil spout moment, gasoline is injected in the engine intake manifold by oil sprayer under certain pressure atomizes, and mix with the air draught that enters, enter the engine chamber burning, thereby guarantee that motor always works in the optimum state.
Electronic fuel injection engine can accurately be controlled the quality of mixed gas, guarantees that the fuel combustion in the cylinder is complete, makes exhaust emissions and the fuel consume can both be well controlled, and charging efficiency, power and the moment of torsion of motor are effectively improved.
The motorcycle electric spraying motor is installed on the engine throttle owing to oil sprayer, owing to the mounting point of oil sprayer and angle and engine intake manifold have the reason of certain-length, the oily Shu Buneng that causes oil sprayer to spray arrives on the valve seat insert of cylinder head, but cause wet wall at the air flue inwall, cause the oil mass wretched insufficiency that enters the firing chamber, particularly, make the engine oil deficiency in the cold machine stage, consequence be may cause car load to be difficult to start, discharging is not up to standard and be short of power.
Therefore, need transform electric injection system, prevent because the oil bundle that oil sprayer sprays causes wet wall at the air flue inwall of cylinder head, and the oil mass wretched insufficiency phenomenon that enters the firing chamber that causes is avoided because the engine oil deficiency car load that may cause is difficult to start, discharge not up to standard and real and potential problem such as be short of power.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of motorcycle engine electric spray system, change the mounting point and the angle of oil sprayer, the fuel oil bundle that assurance is sprayed is over against the valve valve of motor, prevent because the oil bundle that oil sprayer sprays causes wet wall at the air flue inwall of cylinder head, and the oil mass wretched insufficiency phenomenon that enters the firing chamber that causes is avoided because the engine oil deficiency car load that may cause is difficult to start, discharge not up to standard and real and potential problem such as be short of power.
Motorcycle engine electric spray system of the present invention, comprise fueling injection equipment, air feeder and control unit, described fueling injection equipment comprises oil pump and oil sprayer, air feeder comprises air throttle, fuel oil that oil sprayer sprays and combustion-supporting air are successively by being fixedly installed on the engine intake manifold on the air throttle, the engine cylinder head air flue and the engine air family of power and influence that are communicated with engine intake manifold enter motor, fixedly install oil injector seat on the described engine intake manifold, oil sprayer is fixedly installed on the oil injector seat and communicates with engine intake manifold, the position being set and angle a being set of described oil injector seat can guarantee the valve valve of the fuel oil bundle of oil sprayer ejection over against motor, and can make the fuel oil bundle of ejection arrive the valve valve, angle a is the angle between oil injector seat center line and the engine cylinder head air flue suction port center line.
Further, described engine intake manifold is fixedlyed connected with engine cylinder head by flange, and the elasticity heat insulating washer is set between the junction surface of described flange and engine cylinder head;
Further, the junction surface of described flange is provided with annular groove, and described elasticity heat insulating washer is arranged in the annular groove;
Further, described elasticity heat insulating washer is an O type rubber seal;
Further, described oil injector seat and engine intake manifold are set to one.
The invention has the beneficial effects as follows: motorcycle engine electric spray system of the present invention, oil sprayer is fixedly installed on the engine intake manifold by the oil injector seat on the engine intake manifold, change the mounting point and the angle of oil sprayer, the fuel oil bundle that assurance is sprayed is over against the valve valve of motor, prevent because the oil bundle that oil sprayer sprays causes wet wall at the air flue inwall of cylinder head, and the oil mass wretched insufficiency phenomenon that enters the firing chamber that causes is avoided because the car load that the engine oil deficiency may cause is difficult to start, discharge not up to standard and be short of power and wait real and potential problem.
