2009 Ruifeng gasoline utility vehicle cannot start while idling. It must be refueled to start.

1. Black smoke coming from the exhaust:

This means that the engine mixture is too rich, resulting in insufficient combustion. When the air filter is too dirty, the spark plug is defective, the ignition coil is defective, etc., the engine will emit black smoke.

2. White smoke coming from the exhaust pipe:

This means that the injector has poor atomization or the oil is leaking, preventing some of the gasoline from burning; essence ; there is a problem with the cylinder head and cylinder liner. There are cracks invisible to the naked eye, the cylinder seal is damaged, and water enters the cylinder. The machine temperature is too low; It can be solved by the following methods: cleaning or replacing the injector, adjusting the injection pressure; eliminate moisture in the fuel tank and oil system; do not buy cheap and substandard oil; cylinder head.

3. Blue smoke comes from the exhaust pipe:

This means that engine oil enters the combustion chamber to participate in the combustion of the ring piston and cylinder liner. are not completely broken in and engine oil is entering through the gap; the piston ring is stuck in the groove and the piston ring cone is installed upside down and the oil scraping effect is lost excessively; worn out and oil flows into the combustion chamber from the opening space; the oil level in the oil pan is too high; the valve and guide are worn and the gap is too large. It can be solved by the following methods: new cars or overhauled locomotives must operate in the engine according to regulations so that all parts can mesh normally; clearly read the assembly marks and correctly install the piston rings by segmenqualified or enlarged piston ts; sizes; check the oil base. The reason why the hull oil level rises is to drain excess oil from the oil pan, reduce the oil in the filter oil pan, and replace the valve guide;
