LPG system maintenance: 10 instructions from BRC

Learn 10 tips from BRC for LPG system maintenance: guaranteed safety, efficiency and durability with the right care for your vehicle. 

The LPG system is an increasingly popular solution for those who want to reduce fuel costs and emissions. However, to ensure safety and optimal performance, it is essential to follow proper maintenance. Some checks can be done independently, while others require the services of a trained technician.

Below you will find 10 essential instructions from BRC, divided between checks you can do yourself and work that requires a specialized technician.

Checks you can do independently

Some checks on the LPG system can easily be done independently, without the need to call in a technician. Performing these checks regularly will allow you to keep the system efficient and extend its life, avoiding inconvenience and costly repairs.

1. Refuel only at reliable distributors

The quality of LPG can vary depending on the supplier. Poor quality fuel may contain impurities that, over time, could impair the operation of the injectors and pressure reducer.

To avoid inconvenience, always choose reliable distributors.

Also, make sure that when refueling, the LPG tank filling does not exceed 80% of the total capacity.

In this way, risks of damage to the parts of the tank's multivalve, the device that regulates various safety-related controls, such as overpressure, level indication, and proper charge flow, can be avoided.

2. Properly alternate LPG and gasoline

To preserve the engine and the system, it is important to use gasoline mode as well. This helps keep the fuel system running efficiently and prevents any malfunctions to the original gasoline system.

Prevent the gasoline tank and the LPG tank from emptying completely. It is necessary to always keep 1/4 or 1/2 of the tank filled with gasoline and renew it periodically.

This is also because some systems include the option of activating a strategy that allows the vehicle to run for short periods on gasoline, without any warning to the driver from the switch.

3. Check for gas odors

If you detect a gas odor inside the passenger compartment or near the vehicle, switch to gasoline mode and go to an authorized BRC workshop for an inspection. A gas leak, while rare, could indicate a need for maintenance on the pipes or valves.

It is important not to ignore these signs, as an LPG system in perfect condition should never release unpleasant odors.

4. Monitor fuel consumption and vehicle performance

Monitoring the fuel level is critical to avoid running out of gas. BRC systems are able to recognize the inability to properly fuel the engine due to running out of gas or due to low gas supply pressure.

In such a situation, with the button in the “automatic” position, an automatic switch from gas to gasoline is implemented and the vehicle can run for short periods on this type of fuel.

The system can automatically switch back to gas operation if it is able to feed the engine properly.

If, on the contrary, the system recognizes that it can no longer feed the engine on gas, the driver is alerted by a repetitive beeping sound and the lighting of the gasoline LED on the switch. The beeper can be turned off by pressing the switch in gasoline mode.

At this point, refueling is required to achieve normal gas vehicle operation again.

The gas-petrol switching strategy can also be adopted, in special cases and for brief moments, in order to optimize vehicle operation.

5. Start the engine properly

During winter, the engine may take longer to switch to LPG mode. Avoid forcing the switch and let the system switch automatically when the engine has reached the ideal temperature. This reduces the risk of damaging the system and improves combustion.

Interventions that require a trained technician

Other interventions on the LPG system require the services of a specialized technician who has the skills and tools needed to ensure accurate and safe work. These interventions are essential to ensure that the system is working properly. Relying on qualified professionals is essential to maintain the efficiency and safety of the LPG system.

6. Have a free service within the first 1,000 to 1,500 km.

After the LPG system has been installed, an initial check-up should be carried out at the workshop that performed the installation. This coupon is used to check that the system has been installed correctly and is working optimally. The early check allows for early action on any minor settlements in the system.

You can look for the specialized technician at an authorized BRC workshop.

7. Subject the system to periodic inspections.

To ensure optimal performance and safety, the LPG system should be checked every 20,000 km or once a year, however, following what is stated in the LPG system owner's manual. Revisions may include checking emissions, the reducer, injectors, and the tank.

In addition, according to Ministry of Transport Circular No. B76/2000/MOT, the LPG tank must be replaced 10 years after testing. The operation must be performed by an authorized workshop to ensure compliance with regulations and proper operation of the system.

8. Check the LPG filter.

The LPG filter is essential to retain any impurities in the gas. A dirty filter can affect the proper functioning of the injectors.

It is recommended to replace it every 20,000 km or otherwise according to the instructions in the BRC maintenance booklet. Regular maintenance of the filter improves combustion and reduces the risk of carbon deposits in the engine.

9.Check the carburation parameters.

The correct balance of the mixture between Butane and Propane in LPG is essential for the proper functioning of the system.

Any irregularities in the carburation parameters can cause power loss or anomalies in the system. For this reason, it is important to perform periodic checks using the appropriate diagnostic tools supplied to BRC network workshops.

10. Inspect pipes and fittings periodically.

The pipes and fittings of the LPG system are the pipes and joints that connect the various components of the system, such as the tank, pressure reducer, injectors and engine. They should be checked regularly for signs of wear or leaks.A qualified technician can check the condition of the seals and connections, ensuring maximum system safety.
It is advisable to perform these checks at each service to ensure that the system remains in perfect working order at all times.

Conclusion

Following proper maintenance of the LPG system is essential to ensure safety, efficiency and durability.
Some checks can be done independently, such as monitoring consumption or choosing quality fuel, while others require the intervention of a specialized technician.
Complying with periodic reviews and relying on BRC-qualified professionals will allow you to travel with peace of mind, optimizing vehicle performance and reducing the risk of mishaps.
