What are the reasons for a gasoline-to-gas converted vehicle stalling when switching to gas?
4 Answers
Main reasons for a gasoline-to-gas converted vehicle stalling when switching to gas include improper gas volume adjustment during the conversion process, which requires readjustment. Below are specific maintenance methods for gasoline-to-gas converted vehicles: 1. Device maintenance: Regular device maintenance is essential for gasoline-to-gas converted vehicles. Due to the special properties of the fuel used, a comprehensive leak test should be conducted on the gas tank every two weeks. 2. Driving habits: Proper driving habits are key to maintaining good performance in gasoline-to-gas converted vehicles. During daily driving, it is also important to ensure that fire extinguishing equipment is available inside the vehicle. If the vehicle is to be parked for an extended period, the CNG should be depleted. Repairing the gas supply system in enclosed garages or workshops is prohibited. 3. Routine maintenance parts: Gasoline-to-gas converted vehicles may experience stalling during driving due to improper cleaning of the air filter, improper adjustment of the fuel injection simulator's injection delay, or issues with the pressure reducer's adjustment.
Oh, I also encountered this problem after converting to a gas system before. It’s really frustrating when the engine stalls during the switch. There are quite a few possible causes: the most common one is insufficient gas supply, such as a faulty gas pump or unstable pressure; it could also be a malfunctioning switch that sends wrong signals during the transition, causing the ECU to lag. Additionally, if the gas filter is clogged, the airflow gets disrupted, making ignition difficult. Another issue could be an imbalanced air-fuel mixture—the conversion system requires precise calibration. If the technician lacks skill or uses outdated equipment, the ratio between gasoline and gas might be off, leading to incomplete combustion and stalling. Oh, and worn-out spark plugs can also cause trouble since gas is harder to ignite than gasoline, so a weak ignition system can fail. It’s important to regularly check these components, especially in cold weather when gas lines are more prone to issues. Make sure to get it professionally adjusted in time to avoid bigger troubles like breaking down on the road.
I've been driving a modified car for several years, and the issue of stalling after converting to LPG (Liquefied Petroleum Gas) essentially boils down to poor coordination in the conversion system. Loose gas pipelines or fittings can cause gas leaks and supply interruptions; improper adjustment of the ECU (Engine Control Unit) may lead to engine RPM instability during fuel switching; a faulty oxygen sensor can disrupt feedback signals, resulting in insufficient gas supply; additionally, excessive carbon buildup on ignition coils or spark plugs can impair ignition efficiency. Once these components fail, starting becomes difficult, requiring step-by-step troubleshooting: first, check if the gas valve opens normally, then listen for abnormal noises during switching; clean the gas filter to prevent clogging; replace spark plugs to see if performance improves. Don’t underestimate routine maintenance—while LPG conversion saves fuel, the system becomes more delicate. Regular upkeep can prevent most issues and ensure a smooth driving experience.
When the engine stalls during gas switching, I always pull over to calmly analyze the key points. Insufficient gas pressure is the prime suspect—a faulty pressure regulator can cause a sudden drop. Poor contact in the converter switch may also lead to instant power loss. Additionally, ECU control disorder with signal errors can disrupt accurate gas supply. Regular checks on gas tank pressure and pipeline sealing save a lot of hassle. Ensuring system upgrades are compatible with the original vehicle computer prevents conflicts.
