Abstract

The invention discloses an electronically-controlled gasoline injection system for motorcycles. The system comprises an electronic control unit, an engine operation condition data collection subsystem, an electronic throttle valve control subsystem, a common rail gasoline injection subsystem and a digital ignition subsystem. According to the system, the electronic control unit serves as a control center, and optimal working parameters are obtained through data collection of the engine operation condition data collection subsystem; according to the shifting degree of an accelerator, the electronic control unit adjusts the air inflow of an electronic throttle valve by driving and controlling a stepping motor; according to the fuel output pressure, the electronic control unit adjusts the fuel injection quantity and the fuel injection time by controlling the common rail gasoline injection subsystem; and according to the position of an engine crankshaft, the electronic control unit controls the ignition time and the charging time of a high pressure pack through the digital ignition subsystem. Thus, fuel injection and ignition can be accurately controlled, the air-fuel ratio can be controlled in real time, an engine can work on the optimum condition, and fuel conservation and emission reduction of the motorcycles can be realized.

Description

technical field [0001] The invention relates to the technical field of gasoline injection, in particular to an electronically controlled gasoline injection system for motorcycles. Background technique [0002] At present, my country's motorcycle output ranks first in the world, but most of the motorcycle's oil supply system still uses carburetors. The carburetor is generally controlled mechanically through the throttle cable, and uses the opening of the metering hole and the throttle valve to control the fuel supply of the engine under various working conditions. It has the disadvantages of high fuel consumption and difficulty in controlling exhaust emissions. With the continuous development of the market and the promulgation of National IV emission regulations for motorcycles, carburetors will be difficult to meet the needs of motorcycle development. Therefore, the use of EFI technology for motorcycles is an inevitable trend in future development. Contents of the inventio...
