A single-cylinder diesel engine slows down when it dreams of refueling.

If the diesel engine fails to supply oil intermittently, it is mainly because the throttle is blocked. There are many reasons for the blockage of the oil circuit, such as the blockage of the gasoline filter, the blockage of the oil nozzle, and the insufficient pumping pressure of the gasoline pump. It is also possible that the three-way catalyst and exhaust pipe of the exhaust system are blocked, too much carbon is deposited in the throttle, and the idle position sensor and air flow meter are broken.
