What Causes the Jerking When Refueling a Natural Gas Vehicle?

[SanAdaline]

Natural gas vehicle jerking during refueling can be attributed to the following reasons: Natural gas vehicles often experience backfiring: Backfiring is caused by an overly lean air-fuel mixture, which can result from various factors. These include improper adjustment of the mixer leading to a lean mixture, lack of regular maintenance causing air leaks in the intake manifold and resulting in a lean mixture, and prolonged driving on mountainous or uneven roads that displace the air filter covers, allowing excessive air to enter the cylinders and creating a lean mixture. Insufficient power in natural gas vehicles: When converting a vehicle to run on natural gas, the original engine structure remains unchanged to accommodate both fuel and gas conditions. As a result, the vehicle's power output typically decreases when using natural gas, usually by about 5-15%.
