What is the reason for the lack of power and acceleration of diesel vehicles?

The specific reasons for poor acceleration of diesel engine due to insufficient power are as follows: 1, carbon deposit: carbon deposit includes cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit, etc. These positions are closely related to the power output of the engine. When there is too much carbon in the engine, the ignition energy of the automobile decreases and the intake efficiency decreases, which eventually leads to the decrease of engine power and insufficient power and acceleration. 2. Fuel system: adding an inappropriate fuel label will lead to a decline in the output power and power of the car; Or because the vent hole of the fuel tank cover blocks the switch of the fuel tank, the fuel filter and the fuel pipe between the fuel tank and carburetor can't meet the required oil supply, resulting in too thin mixture and weak engine acceleration. 3. Air intake: If the air filter is not cleaned in time after long-term use, insufficient air will lead to excessive concentration of combustible mixture and reduce engine power. If it is a vehicle with a turbocharger, once the booster fails, even if the throttle is given, the engine is still dull and the power is still insufficient. 4. Engine overheating: insufficient engine oil, insufficient engine coolant and failure of engine cooling device will increase the load of the engine and even lead to poor engine cooling. Engine overheating will cause poor lubrication effect, increase mechanical wear, reduce engine power, and lead to weak engine acceleration.
