An LPG system in a car is a convenient and cost-effective solution, but like any other component, it requires regular inspections to ensure proper operation. While a full diagnosis should be performed by a professional service, knowing the most common signs of LPG system issues can help you react quickly and avoid costly repairs. Self-diagnosis can help detect early problems before they become serious.
Loss of Engine Performance
If you notice that your car has lost power, it may indicate problems with the LPG system. A drop in power is one of the most common signs of malfunction and may be caused by:
- Clogged gas injectors – Contaminants in the fuel system can lead to improper gas dosing, affecting engine power.
- Incorrect air-fuel mixture adjustment – An improper ratio of air and gas can weaken engine performance.
- Reducer failure – The reducer regulates gas pressure in the system, and its malfunction can cause engine instability and power loss.
To check whether the problem is related to the LPG system, compare the engine’s performance on gasoline and gas. If the power drop occurs only when running on LPG, the issue likely lies in the system.
If you notice any of these symptoms, visiting an LPG service center in Warsaw can help prevent more severe failures.
Increased Fuel Consumption
A sudden rise in gas consumption may be due to several factors. Pay attention to:
- Leaks in the LPG system – Gas leaks can lead to excessive fuel consumption, as the system won’t function efficiently.
- Worn-out gas filters – Clogged filters restrict gas flow, forcing the engine to burn more fuel to maintain the same power.
- Incorrect LPG controller settings – A poorly configured controller improperly adjusts the fuel mixture, increasing consumption and possibly reducing performance.
Regular replacement of gas filters and calibration of the LPG system controller is recommended to maintain optimal fuel efficiency.
Problems Switching to Gas
If your car has difficulty switching from gasoline to LPG or frequently reverts to gasoline on its own, possible causes include:
- Low reducer temperature – In winter or cold conditions, the reducer may not reach the required temperature, preventing gas operation.
- Faulty gas pressure sensor – If the sensor malfunctions, the system may not recognize when it should switch to gas.
- Defective LPG system controller – The controller, responsible for fuel switching, may be faulty, causing frequent and uncontrolled reversion to gasoline.
If the problem persists, it is best to visit a service center for a detailed system diagnosis.
Rough Engine Operation at Idle
Vibrations and irregular RPMs while idling often indicate LPG system problems. The most common causes include:
- Faulty gas injectors – Malfunctioning injectors can cause unstable engine operation.
- Contaminated air intake – A dirty air filter or intake pipes can lead to rough idling, especially when running on gas.
- Incorrect gas pressure – If the gas pressure is too high or too low, the engine may run unevenly, causing vibrations when idling.
Additionally, monitor whether symptoms worsen after switching to gas or if they occur only at certain RPMs.
A professional diagnosis from a trusted service, such as Gaz Time Warsaw, can quickly detect and fix any issues, ensuring safe and economical driving.
Gas Smell in the Cabin or Around the Car
If you smell gas, immediately inspect the LPG system for leaks. Any gas leaks are dangerous and can lead to serious malfunctions or even fire. The most common causes are:
- Leaky gas pipes – Over time, gas pipes can wear out or get damaged, causing leaks.
- Damaged connectors and seals – The connections between LPG system components must be airtight to prevent leaks.
- Leaks in the reducer – A damaged reducer can be a source of leaks, which are particularly hazardous.
If you notice any signs of a gas leak, immediately contact an LPG service center to prevent serious problems.
Conclusion
While self-diagnosing an LPG system can help detect early problems, professional inspection and maintenance are crucial to ensure safe and efficient operation. Regular servicing, proper adjustments, and timely filter replacements can extend the system’s lifespan and improve overall vehicle performance. If you experience any issues, a visit to a professional LPG service center can prevent costly repairs and keep your car running efficiently.
