What is the reason for the slow speed after stepping on the accelerator?

The reasons for the slow acceleration of a car after stepping on the accelerator are clutch slip, poor oil quality, carbon deposition on the accelerator, small vehicle displacement and heavy load, engine system failure, ECU control element failure and so on.

Clutch Slip: Clutch Slip is mainly manifested in the fact that when the car accelerates, the vehicle speed cannot be increased with the increase of engine speed, and the power of the engine cannot be fully transmitted to the driving wheels, resulting in driving weakness, especially when going uphill. The main reasons for clutch slip are insufficient friction of clutch friction plate, long-term semi-clutch sports car, clutch slip and so on.

Poor oil quality: poor oil quality will affect the gasoline filter and oil circuit, resulting in poor oil supply and poor acceleration.

Throttle carbon deposit: Throttle carbon deposit will affect air intake.

Engine failure: the power source is the combustion of fuel, and the engine is responsible for providing fuel and converting chemical energy into mechanical energy. Therefore, in the case that the vehicle cannot speed up when refueling, the engine system should also be taken as the key inspection. Any part of the engine air intake system, oil circuit system and ignition system is out of order or abnormal. If the air filter, throttle and other components are blocked or have problems, resulting in insufficient air intake, the air intake system will fail. If the engine oil is insufficient for a long time and the optical power is insufficient, the fuel consumption will increase; The heavy piston hits its door, causing mechanical damage to the relevant connector. In addition, the failure of gasoline pump and the blockage of fuel filter will also lead to the decrease of engine power.
