The invention relates to a diesel / methanol combined combustion diesel engine, in particular to a diesel / methanol combined combustion diesel engine accelerator position signal collection device and method. The diesel / methanol combined combustion diesel engine accelerator position signal collection device comprises an L-shaped support, a support rocker arm 7, a sensing rotating shaft 14 and an angular displacement sensor 4. The device and the method for collecting the position of a traditional line pump diesel engine accelerator can be realized, the real-time monitoring of the diesel injection quantity of a traditional mechanical diesel engine can be realized, the diesel / methanol composite combustion fuel is precisely controlled, the methanol and the diesel are mixed to be combusted at a gaseous state, and not only is the good performance of the pressure combustion way of the diesel engine guaranteed, but also the emission of promethium (PM) and nitrogen oxide (NOX) of the diesel engine can be reduced.
Description
Technical field: [0001] The invention relates to a diesel / methanol combined combustion diesel engine, and further relates to a device and method for acquiring throttle position signals of a diesel / methanol combined combustion diesel engine. Background technique: [0002] Due to its good economy and reliability, diesel engines are widely used not only in trucks and city buses, but also in cars. However, the inherent particulate PM and nitrogen oxide NO of the diesel engine X The emissions are relatively high, and there is a trade-off relationship between these two emissions. As people's requirements for the environment are getting higher and higher, and regulations are becoming stricter, PM and NO X Emissions have become the key to restricting the development of diesel engines. The existing methods to solve this contradiction include: (1) adopting high-pressure common rail technology combined with exhaust gas post-treatment and other high-tech technologies on diesel engine...
