What are the symptoms of a faulty LPG pressure reducer valve?
2 Answers
Damage to the LPG pressure reducer valve manifests as unstable idling and poor acceleration. Below are specific maintenance methods for LPG-converted vehicles: 1. Device maintenance: Regular device maintenance is essential for LPG-converted vehicles. Due to the special nature of the fuel used, a comprehensive leak inspection should be conducted on the gas tank every two weeks. 2. Driving habits: Proper driving habits are crucial for maintaining the performance of LPG-converted vehicles. Before driving each day, in addition to following the original car manual checks, inspect all pipelines for cracks or oil leaks. If the vehicle is to be parked for a short period, ensure the main power switch and the CNG cylinder valve are closed. Additionally, always keep fire extinguishing equipment inside the vehicle during daily driving. For long-term parking, the CNG should be completely used up. Never repair the gas supply system in enclosed garages or workshops. 3. Routine maintenance parts: LPG-converted vehicles may experience stalling during driving, which can be caused by improper cleaning of the air filter, incorrect adjustment of the fuel injection simulator's delay, or improper adjustment of the pressure reducer.
I remember when the pressure relief valve was broken, driving became extremely uncomfortable. The car felt powerless, and stepping on the gas pedal was like dragging a huge mountain—acceleration was painfully slow. After struggling to climb a hill, the RPM would suddenly drop, and the entire engine would shake with uneven power output. Starting the car was even more troublesome—it took several presses of the ignition button, and if luck wasn’t on my side, I had to wait for someone to help push-start it. Idling was unstable, fluctuating up and down, and the car would shake like it was dancing disco even when parked. Sometimes, a hissing sound could be heard from the engine bay, as if there was a gas leak, which was quite alarming. If the leak worsened, it could pose a safety hazard. Fuel or gas consumption would increase, wasting all the money saved on cheaper fuel. I initially converted to gas for cost savings, but after this issue, not only were repairs expensive, but it also caused delays. Once, it broke down during a long trip, which was incredibly frustrating. My advice is to get it checked as soon as these symptoms appear—don’t wait for a major problem to occur.
