What's the matter that the cold car can't add gas?

There are many reasons why cold cars can't be fueled. Common reasons are as follows:

First, the cause of the oil circuit

1. Inferior oil. Dilution of mixed gas leads to insufficient thrust of gas on piston, prolonged combustion time and overheating of engine after ignition and explosion. The reason for judging poor engine oil is poor acceleration in operation. Acceleration with manual throttle or oil pump is improved, but it is weak when rich gas mixture is not used.

2. Rich in oil. The mixture is so thick that the motorcycle can't accelerate at low speed. Due to the lack of oxygen when the mixture is too rich, the combustion of the mixture is incomplete, the power is reduced, and the economy is poor. It is easy to produce a large amount of carbon deposits to block the exhaust device, which further aggravates the phenomenon of acceleration weakness. It can be found that the spark plug is easy to soak in oil, there is carbon black deposition on the central surface, and the muffler smokes abnormally when it works, which leads to ignition. Moreover, the fuel consumption exceeds the standard, but the slight oil concentration has little effect on high-speed operation, and closing the damper during operation will aggravate the fault phenomenon.

Second, the circuit reason

1. Bad high voltage spark. High voltage power failure, due to the high and low voltage components and circuits of the ignition system, may cause high voltage flashover discontinuity, make the engine stop working, and weaken the acceleration; The high-voltage spark is red and weak, and the high-voltage electricity is too weak because of the electrical components and circuit faults of the ignition circuit, which makes the engine work badly. Resulting in bad high-voltage sparks.

2. The ignition time is too early. Premature ignition time will produce high-pressure spark ignition, which will bring great resistance to the piston that is rising and compressing. It will not only affect the acceleration performance, but also lead to engine starting difficulties, poor idle speed and accelerated knocking.

3. The ignition time is too late. The ignition time is too late because the best explosion time is missed, which makes the flame stay in the cylinder for a long time, which not only directly affects the acceleration performance, but also causes the engine to overheat, the exhaust pipe to slap and the sound is dull.

Three. Mechanical reasons

1, the failure phenomena of poor inertia in the running part of the car body mainly include: when neutral stall, the operator finds great resistance when pushing the car, and the motorcycle consumes a lot of power in operation, which will inevitably lead to weak acceleration.

4. The vehicle is overloaded by human factors, the road condition is poor, the driving level is poor, and the carburetor enrichment device is not reset.
