Wei Chai's 350-horsepower muck truck sped up and became bored.

The reason why the 350 HP muck truck in Wei Chai is jammed when it is speeding up is that the throttle valve is improperly adjusted and cannot be fully opened.

The air filter is clogged. Malfunction of air flow meter or intake manifold vacuum sensor, coolant temperature sensor and throttle position sensor. If the compression pressure of the cylinder is too low or the valve timing is misaligned, the engine will be weak.

There are other reasons for Wei Chai's 350 HP speed increase: 1. Accelerate the blue smoke, and infer whether it is a problem of piston clearance. It is recommended to check four sets.

2。 It is normal for the accelerator to emit black smoke (if it is a national second, or a mechanical pump). If the throttle doesn't emit black smoke, the engine must accelerate slowly.

3。 The exhaust is blocked, and the vacuum degree of the intake manifold is obviously low when the engine is loaded. The fuel injector is blocked or poorly atomized.
