Beiqi Wangwei 306 gas-to-vehicle ran 82,000 kilometers. What's the matter with burning oil and gas, stepping on the clutch to shift gears and then turning off the fire?

First of all, find out the cause of the flameout. The reason of flameout after changing oil to gas is that the intake air increases at a high speed, which leads to the lean mixture in the cylinder. Secondly: ① If you modified the direct injection type at that time, you can use PC to adjust the gas computer data, increase the injection amount of CNG or replace the injection rail with a slightly larger injection hole; ② If it is self-priming, you can adjust the idle valve on the pressure reducing valve, which is also the simplest way to increase the CNG gas supply. It is easy to seal a part of the intake pipe with sealant tape, or replace the special spark plug for Hunan torch three-pole gas or clean the idle motor on the accelerator, so as to ensure that the problem is solved. Sealing a part of the intake pipe with sealant tape is the simplest way to solve the problem of stalling or stepping on the clutch in high-speed gas burning. Its purpose is to reduce the intake air and indirectly increase the concentration of mixed gas in the cylinder when burning gas, and it has no effect when burning gas. However, when burning engine oil, due to the reduction of intake area, the intake air volume decreases, which will lead to problems such as excessive mixture and increased fuel consumption. So students who rarely burn oil can use this method.
