What Causes an LNG-Powered Vehicle to Lose Throttle Response?
1 Answers
When an LNG-powered vehicle experiences throttle response loss, first check if the pressure gauge reading is normal. If there are pressure issues, inspect all pipelines for potential gas leaks. Next, focus on examining the vehicle's fuel injectors, as LNG vehicles are prone to carbon buildup and rapid aging of injectors during rough operation. If this is the issue, simply replace the corresponding fuel injectors. Here are specific solutions: Refueling: Severe fuel shortage in the vehicle's gas cylinder can be identified through the dashboard fuel level indicator. If levels are critically low, promptly refuel. Fuel Replacement: Poor fuel quality with low calorific value may cause insufficient power output and torque deficiency, leading to acceleration problems. Replace with higher calorific value fuel. Valve Adjustment: Incomplete opening of the gas cylinder outlet valve restricts fuel supply, resulting in weak acceleration. Fully open the valve to resolve. Regular Maintenance: Check for clogged air filters and fuel injectors. Perform regular cleaning and replacement of air filters and fuel injectors.
