engine start control system

Abstract

The invention discloses an engine start control system which comprises a starter, a starting gear ring, a flywheel and a one-way clutch, wherein the starter is used for providing starting power; the starting gear ring is connected with the starter and driven by the starter to rotate; the flywheel is connected with an engine; the one-way clutch is arranged between the starting gear ring and the flywheel, and used for connecting the starting gear ring with the flywheel to enable the starting gear ring to drive the flywheel to rotate. The engine start control system provided by the invention can quickly start the engine timely according to the will of a driver in a shutdown process of the engine, and improves starting performance and driving comfort of a vehicle.

Description

technical field [0001] The invention relates to the technical field of engine starting, in particular to an engine starting control system. Background technique [0002] When the vehicle is driving in the city, due to the relatively high density of pedestrians and vehicles on the city streets, the vehicle starts and stops very frequently, resulting in most of the energy generated by the engine being consumed in the form of friction and heat during frequent starting and braking. , causing problems such as high fuel consumption and aging of the vehicle. On the other hand, in order to achieve the purpose of flexible braking and quick start, vehicles generally have an idling state, but when actually driving in an environment with a relatively high density of pedestrians and vehicles, there may be medium, short or even long periods of parking. Due to the situation, the engine needs to continue to be in the idling state during this process, resulting in problems such as fuel cons...

Problems solved by technology

[0002] When the vehicle is driving in the city, due to the relatively high density of pedestrians and vehicles on the city streets, the vehicle starts and stops very frequently, resulting in most of the energy generated by the engine being consumed in the form of friction and heat during frequent starting and braking. , causing problems such as high fuel consumption and aging of the vehicle

On the other hand, in order to achieve the purpose of flexible braking and quick start, vehicles generally have an idling state, but when actually driving in an environment with a relatively high density of pedestrians and vehicles, there may be medium, short or even long periods of parking. Due to the situation, the engine needs to be in the idling state continuously during this process, causing problems such as fuel consumption waste and pollution. However, if the engine idling state is canceled and the engine cannot be started quickly, this problem has been plagued by technical personnel in the industry.

Starting system When the engine is shut down, the speed of the flywheel and the starter ring gear gradually decreases. Due to the large mass of the flywheel, the pinion gear of the starter cannot mesh with the starter ring gear, otherwise serious gearing will occur, resulting in equipment failure Or scrapped, that is to say, during the engine shutdown process, the starter cannot provide starting power in a timely manner, and can only be restarted to provide power after the engine is completely shut down, which causes the vehicle to start again. Starting performance and driving comfort are greatly reduced
