Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] like Figure 1-2 As shown, the Adam's apple of the engine includes a stepping motor 1, an air passage 2 through which the opening amount is controlled by the stepping motor, an air intake passage 3 communicating with the air passage 2, an oil inlet pipe 4 connected in sequence, an oil injection nozzle 5, Gasoline pressure regulating valve 6 and oil return pipe 7; the intake passage 3 is also connected to the gasoline pressure regulating valve 6; an intake flow measuring sensor 8 is also provided, the input end of which is connected to the intake passage 3, and the output end is connected to the control end of the stepping motor 1 .

[0015] When the engine is working, the air flows into the engine through the intake duct 3, and the intake air flow measuring sensor 8 directly measures the air flow passing through the intake duct 3; Go back to the gasoline pressure r...

Abstract

The invention discloses a motorcycle engine air-fuel ratio control device which is a key part of an engine and comprises an air inlet control mechanism and a fuel control mechanism, wherein the air inlet control mechanism comprises a step motor, an air channel and an air inlet channel, the opening volume of the air channel is controlled by the step motor and the air inlet channel is communicated with the air channel; the fuel control mechanism comprises a gasoline inlet pipe, a gasoline spraying nozzle, a gasoline pressure regulating valve and a gasoline return pipe which are sequentially circularly connected; and the air inlet channel is communicated with the gasoline pressure regulating valve. The device has simple structure and low manufacture cost, can accurately control the air-fuel ratio to reach 16.7:1, has no air resistance and eliminates shortage or interruption of gasoline of the engine.

Description

technical field [0001] The invention relates to a method for controlling the air-fuel ratio of an engine and an engine Adam's apple made according to the method, in particular to a position and a method for an air-fuel ratio component of an electronic control unit of a motorcycle engine. Background technique [0002] Motorcycle EFI control technology started very late. Europe and the United States began to put forward Euro III emission requirements for small-displacement engines in 2007, and the country began to implement the National III emission standards in July 2010. Traditional motorcycles mainly use carburetors to control the air-fuel ratio of the engine, and a small number of electronic control systems use secondary air intake to control the air-fuel ratio. This method makes it difficult to control the air-fuel ratio and cannot achieve accurate combustion control. Contents of the invention [0003] The technical problem to be solved by the invention is that the trad...
