What is the reason for the slow acceleration of auto start?

Pacific car network may be an engine or gearbox problem, which is caused by a fault and needs to be investigated in time. It may also be because the vehicle has a small displacement and a heavy load, and it may not reach the supercharged speed when starting, so it is normal to feel tired when starting.

There are many reasons for the weak start of the car, such as lax valve seal and insufficient cylinder pressure; Due to excessive carbon deposition at the air inlet; Spark plug carbon deposit or incorrect clearance; Nozzle blockage, insufficient fuel injection and so on.

The most common encounter is throttle carbon deposition. Throttle carbon accumulation will affect the intake, and then affect the engine power shortage and automatic start. The solution is to clean the throttle. Failure of gearbox clutch will lead to weak starting of the car. The function of the clutch is to transmit and cut off the power of the engine. Manual gearbox, double clutch and other gearboxes all adopt friction plate clutch. If the friction plate is used for a long time, it will wear seriously, leading to slipping, and then the car can't start.

In addition, too dirty and insufficient transmission oil will also lead to weak starting of the car. For automatic transmission, gearbox oil not only plays the role of lubrication, but also is the medium of internal hydraulic mechanism. These hydraulic mechanisms control the clutch and shift mechanism. Too dirty or insufficient will cause these mechanisms to work badly. (Photo/Text/Photo: Pacific Auto Network Chen Jie 2)
