Crankshaft position limiting system after flameout of automobile engine

Abstract

The invention relates to a crankshaft position limiting system after flameout of an automobile engine, aiming at solving the problem that the engine cannot be quickly started up. The crankshaft position limiting system comprises an engine flywheel, a crankshaft position locking mechanism, a crankshaft position sensor, a crankshaft signal panel and an ECU (Engine Control Unit). The crankshaft position locking mechanism comprises a locking gear, a transmission shaft, a locking wheel, an electromagnetic valve, a traction pushrod, a traction disc, a return spring and an engine body shell. The locking gear is installed at the front end of the transmission shaft. The transmission shaft is assembled with the locking wheel. The electromagnetic valve is arranged at the front of the traction disc. The traction disc is fixedly assembled with the rear end of the traction pushrod. The front end of the traction pushrod penetrates through the locking wheel and then is assembled with the locking gear. The return spring is sheathed in the inner chamber of the engine body shell. The crankshaft position limiting system after the flameout of the automobile engine has the characteristics of simple structure and stable performance, the improvement of quick response performance of vehicle power is facilitated, the engine can be flamed out when the vehicle is stopped for waiting, and not only can the oil consumption of the vehicle be reduced, but also the emission of tail gas can be reduced.

Description

technical field [0001] The invention relates to a system for limiting the position of a crankshaft of an engine, in particular to a system for limiting the position of a crankshaft after an automobile engine is turned off, and belongs to the technical field of internal combustion engines. Background technique [0002] Cars running on urban roads often encounter red lights and other short-term parking waiting situations. Because the existing engine has a start-up delay phenomenon, the engine is in an idling state during a short parking waiting time, which consumes in vain. If a certain amount of fuel can solve the problem of delay in starting the engine, so that the engine can start quickly after receiving the work order, then the engine can be turned off when the vehicle is parked and waiting, which can not only significantly reduce the fuel consumption of the vehicle, but also reduce exhaust emissions , Improve the economic performance and emission performance of the vehicl...
