What is the reason for the sound of the engine guard plate of Ruhai?

If the noise is loud after installation, it may be caused by the resonance of the protective plate and the engine during driving. Common engine protection plates are made of resin, steel and alloy steel. The resin engine guard is made of general-purpose resin, and some manufacturers who keep up with the times adopt a fully closed design.

One situation is that the guard plate rubs against the moving parts outside the engine, causing abnormal noise, and the other case is that the guard plate is close to the vibration frequency of the car, resulting in resonance. Keep the engine compartment clean and prevent water and dust from entering the engine compartment.

Under normal circumstances, as long as the brake engine guard is used, there will be friction and noise. If the noise is irregular when using the brake, it is necessary to check whether the running-in surface of the brake is normal.

Frequently asked questions about abnormal noise in cars. It is difficult for ordinary car owners to distinguish which are faulty abnormal noise and which are reasonable abnormal noise. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

The relationship between abnormal noise and engine speed. The existence of most common abnormal noises in the engine depends on the speed state of the engine. Abnormal sounds only exist during idle or low-speed operation.

How about the engine of the sea

1. Average, not bad. It's better than Hangkai. It's similar to Painier. It's not as good as Baisheng. There is no Yamaha Mercury Bull.

2. Superior engine performance Huanghai n1 engine adopts the latest super engine technology, which has better performance, higher power, higher speed, smaller noise, and more environmentally friendly.Its maximum power is up to 110kw, and its maximum torque is up to 190N·m, which meets the various needs of different users.

3. High fuel efficiency and high environmental protection. After years of technological progress, Linhai Engine has made the engine more environmentally friendly, more energy-saving and fuel-saving. The fuel efficiency has been greatly improved, which can help consumers save expenses and greatly reduce pollution, thus improving the environment.
