Apulia cr 150 cold car started, and the throttle was not working.

The subject asked, "Is there any reason why the cold car of Aprilia cr 150 can't start the throttle?" Insufficient engine temperature, ignition system problems, air intake system blockage and other reasons.

1. Insufficient engine temperature: when the cold car is started, the fuel and engine oil temperature of the engine is low, which leads to the decrease of combustion efficiency. This will cause the fuel injection quantity not to reach the optimal mixing ratio required by the engine, and make the acceleration process feel insufficient power.

2. Ignition system problem: improper ignition time adjustment or ignition coil failure, unstable voltage output. This will affect the normal ignition process, make it difficult to start, and feel insufficient strength when accelerating.

3. The air intake system is blocked: the air intake pipe or air filter is blocked by pollutants, which will restrict the air from flowing into the engine. This will increase the resistance of the engine intake circuit and reduce the number of fresh air circuits available for fuel mixture formation and complete combustion. The result is a feeling of insufficient thrust when stepping on the accelerator.
