| 摘要 |
<p>An electronically controlled fuel injection system of a single-cylinder air-cooled diesel engine, comprising an electric fuel pump (1), a fuel line (2), an electronically controlled fuel injection pump (3), a high-pressure fuel pipe (4), an electronically controlled fuel injector (5), a fuel inlet metering valve (9), and an electronic control unit (6). The fuel inlet metering valve (9) is arranged on the electronically controlled fuel injection pump (3). The fuel inlet metering valve (9) is capable of adjusting the fuel pressure in a pressure accumulation cavity (8) of the electronically controlled fuel injection pump (3). An output end of the electric fuel pump (1) is connected to an input end of the electronically controlled fuel injection pump (3) via the fuel line (2). An output end of the electronically controlled fuel injection pump (3) is connected to an inlet end of the electronically controlled fuel injector (5) via the high-pressure fuel pipe (4). The electronic control unit (6) is connected to the fuel inlet metering valve (9) via an electronic control circuit. The electronic control unit (6) is connected to the electronically controlled fuel injector (5) via the electronic control circuit. The electronically controlled fuel injection system is of automated operation and control and of increased reliability, ensures fuel injection by the electronically controlled fuel injector at an increased pump-end pressure, reduces emission, and increases fuel economy.</p> |
