Types of LPG Car Conversion Kits

Many countries are now adopting the use of LPG as a vehicle fuel. This is because it is cheaper than petrol and more environmentally friendly. A report shows that converting a car to run on LPG cuts CO2 emissions by 15% and almost eliminates NOx and particulate emissions. For business owners looking to reduce their carbon footprint, adopting the use of LPG-powered vehicles is a good decision. However, an LPG car conversion kit is required to convert a petrol or diesel car to run on LPG. There are different types of LPG car conversion kits as explained below.

• Sequential Systems

  The most common type of LPG conversion kit for modern cars with electronic fuel injection is the sequential system. This system injects liquid petrol gas (LPG) into the intake valves of the engine, similar to how petrol is injected in a petrol-fueled car. The LPG injection occurs in a sequence that matches the firing order of the engine's cylinders. The LPG conversion kit uses an LPG distributor to ensure that the gas is injected into the correct cylinder at the right time. As a result, the engine runs more efficiently and with optimal performance. Cars with sequential systems tend to have smoother performance when using LPG.

• Venturi Systems

  Venturi systems are older and simpler compared to the sequential system. This type of LPG car conversion kit is mostly used in older cars that have conventional carburetors instead of electronic fuel injection. Venturi systems use a venturi tube in the carburetor to mix air, petrol, and LPG. The venturi tube creates a vacuum that draws LPG from the storage tank and injects it into the airflow. Unlike the sequential system, venturi systems do not have LPG injectors. Instead, the venturi tube itself acts as a pump to mix the LPG with air. Venturi systems are less precise in controlling the LPG-air mixture, which can result in less efficient combustion and slightly lower engine performance. Due to their simpler design, venturi systems are generally more affordable than sequential systems.

• Bi-Fuel Systems

  Another type of LPG conversion kit is the bi-fuel system. This system allows the car to run on both petrol and LPG. When installing a bi-fuel system, a petrol-fueled car is converted to use LPG. The car's engine management system is also upgraded to handle the switch between the two fuels seamlessly. The bi-fuel system provides flexibility and convenience for drivers. When starting the engine, petrol is used automatically. As the engine reaches its optimal operating temperature, it can seamlessly switch to LPG. This ensures smoother fuel transition, better emissions control, and improved engine performance over its lifespan.

Specifications and maintenance of lpg car conversion kits

• Regular Inspection:

  Inspect all components of the conversion kit regularly, including the tank, valves, pipes, and injectors. Check for any signs of wear, damage, or leaks. Do a visual inspection of the LPG tank and distribution pipes for corrosion, cracks, and deformation. Check whether all valves and connections are intact to avoid gas leaks. Even minor damage can result in dangerous LPG leaks. It is necessary to ensure the safety of vehicle operation by regular inspection of conversion kit components.

• Replace Filters:

  Gas filters in the LPG system should be replaced periodically according to the manufacturer's recommendations. These filters prevent impurities and particles from entering the gas supply. If the filters are clogged or dirty, they can reduce gas flow and affect engine performance. It is better to change the filters before they start to influence the system's efficiency. The interval for gas filter replacement may be about 20,000-30,000 kilometers or once a year, whichever comes first.

• System Bleeding:

  After performing any maintenance work or replacing components, bleeding the LPG system is essential to remove any trapped air or impurities. To bleed the system, open the bleed valve (if available) or loosen the gas lines at the injectors. Allow any air or residual gas to escape before tightening the connections. System bleeding ensures the proper operation of the LPG injection system and prevents potential problems.

• Professional Maintenance:

  It is advisable to have the LPG conversion kit serviced by qualified professionals. Certified specialists have the necessary knowledge and skills to perform complex maintenance and repair tasks. They use specialized tools and diagnostic equipment to ensure the LPG system's safety and efficiency. Moreover, some manufacturers may require professional maintenance to keep the warranty valid.

• Tank Replacement:

  LPG tanks have a limited service life, usually 10-15 years. After this period, the tank must be replaced, even if no damage or wear is visible. Professional LPG specialists should carry out tank replacement due to the complexity and safety requirements of the procedure. They ensure proper installation of the new tank and tightness of all connections.

• Valve and Regulator Check:

  The LPG conversion kit contains several important components, including valves and regulators. It is necessary to regularly check their performance and adjust them if necessary. The valves control the flow of gas, and the regulators maintain the required pressure level in the system. Improper operation of these components can lead to gas supply problems and affect engine performance.

• Quality Spare Parts:

  When replacing any components of the LPG conversion kit, use only original spare parts or high-quality analogs recommended by the manufacturer. This will ensure compatibility and reliability of the system. It is better to avoid using cheap or unknown brands of spare parts, as this may lead to malfunctions and reduce the lifespan of the LPG system.

How to Choose LPG Car Conversion Kits

Wholesale buyers can consider the following factors when purchasing LPG car conversion kits:

• System Type

  Selecting the appropriate type of system is essential. Venturi systems are less complicated and more affordable, while mixer and injection systems offer better performance and efficiency for more modern and higher-performing vehicles.

• Quality and Compliance

  It is important to ensure that the kits meet local standards and regulations. The kits should be sourced from reputable manufacturers that have obtained relevant certifications to ensure safety and quality.

• Vehicle Compatibility

  It is essential to consider the type and model of the vehicle that will be installed with the LPG kit. Some kits are specifically designed for certain makes and models, so buyers should ensure that the kit they purchase is compatible with their vehicle.

• Tank Size and Placement

  The size of the LPG tank is determined by the vehicle's available space and the required driving range on LPG. Additionally, the location of the tank should be considered, as it must be installed in a safe and suitable area on the vehicle.

• Installation and Support

  Buyers should consider the ease of installation of the kit and whether installation instructions and technical support are provided. Some suppliers may offer installation services or technical support, which can be helpful for buyers who are not experienced in installing LPG systems.

• Price and Warranty

  Comparing prices from different suppliers is essential to ensure that the kits purchased offer reasonable value. Additionally, buyers should check the warranty and after-sales service provided by the supplier to ensure that they can obtain support and assistance if needed.
