There is an air plug on Yinglang engine. What is this?

The plug is the one next to the three-way catalyst under the exhaust pipe, which is circulated by the engine. If it breaks down, it will leak water, and the engine will heat up when driving. If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition speed of the cylinder, which will hinder the ignition of the engine and cause insufficient power, and the fuel consumption of the vehicle will naturally increase.

The cause of engine buzzing

The reasons for the humming of the engine with fuel filling may be excessive carbon deposit, poor filtration, insufficient gasoline purity, aging of spark plugs, engine problems, cylinder problems and idling problems. Solve the problem of engine buzzing at the fuel filler door. The hum caused by too much carbon deposit can be divided into too much carbon deposit in engine, too much carbon deposit in throttle and too much carbon deposit in spark plug. Just go to the repair shop and clean it.

Hum caused by poor filtering is the most common problem. The air filter element is too dirty, so it can be cleaned or replaced in the repair shop. For example, 90 # gasoline is not as pure as 93 # gasoline, so it can be replaced by high-grade gasoline. Spark plug aging, engine problems, cylinder problems and idling problems require engine maintenance in the repair shop.
