The Ultimate Guide to LPG Carburetor

table of contents


LPG is an increasingly popular alternative fuel source for a variety of applications including petrol generators, small gasoline engines.Switch your petrol engine to LPG and enjoy lower emissions, fuel costs and longer engine life. A key component of an LPG conversion is the carburetor, which efficiently mixes LPG with air for optimum engine performance. In BISON's concise guide, learn about LPG carburetors, their advantages, installation, common questions, and safety tips.

What is an LPG carburetor?

LPG carburetor and air are mixed in the proper ratio before being introduced into the engine. Its primary function is to ensure the correct mixing of the fuel and air mixture, promoting optimum engine performance, smooth operation and increased efficiency. Precise mixing enables complete combustion, reduces emissions and supports cleaner engine operation. Overall, LPG carburetors play a vital role in the successful conversion of gasoline engines to LPG fuel systems.


Advantages of Using LPG Carburetor

Several benefits of using an LPG carburetor generator conversion include:

Reduced Emissions: LPG burns cleaner than gasoline, reducing harmful emissions such as carbon monoxide, nitrogen oxides, and particulate matter. This makes LPG a more environmentally friendly fuel option.

Lower fuel costs: LPG is generally cheaper than gasoline, which can provide significant cost savings over time, especially for high fuel-guzzling applications like engine generators. For supply and wholesale businesses, this can translate into higher profitability.

Longer Engine Life: Compared to gasoline, LPG has a higher octane rating, resulting in a more efficient and smoother combustion process. This reduces engine wear and potentially increases engine life.

Versatility: Many BISON LPG carburetor allow dual fuel operation, meaning the engine can still run on gasoline if desired. This provides flexibility and ensures that you always have a fuel source available to your customers.

Premium Components: BISON is known for its high-quality components and reliable performance, ensuring successful conversions and long-lasting results. This reputation can be an asset to supply and wholesale businesses looking to offer LPG carburetors to their customers.

How does LPG generator carburetor work?

LPG generator carburetor converts liquefied petroleum gas (LPG) into the combustible gases required by the engine. Liquefied petroleum gas and air mix in the carburetor chamber to form an atomized mixture. This mixture is then sent to the engine's cylinders where it is burned to generate electricity for a generator.

How to Install an LPG Carburetor - Step by Step Guide

Before starting the installation, make sure your specific engine model is compatible with the LPG conversion and gather all necessary tools and safety equipment. The following steps outline the general installation process:

Step 1: To remove the air filter, first locate the air filter housing on the alternator. Remove it with a screwdriver or wrench - tool depends on the fasteners used. Don't unlearn to save the screws, as they will need to be fastened back later.

Step 2: Next, tear down the fuel line from the carburetor. Once took it out, remove the carburetor and set it aside.

Step 3: Using the hardware provided to install the LPG carburetor, attach the regulator to the designated mounting location on the gasoline generator. Make sure the adjuster is securely fastened.

Step 4: Reinstall the air filter housing by securing it with the original screws or bolts.

Step 5: Follow the instructions included with the LPG carburetor to connect the LPG tank to the regulator. Make sure all connections are tight and secure.

Step 6: Test the generator by turning on the LPG fuel supply and starting the generator according to the manufacturer's instructions. Check for leaks around the connections and listen for unusual sounds. If all is well, you have successfully converted your generator to run on LPG fuel.

Common problems may occur in the LPG carburetor

While LPG carburetors are generally reliable, there are some common problems that can arise:

Poor engine performance: If the engine is running poorly or has reduced power after switching, it may be due to an improper air-fuel mixture. Adjust carburetor settings according to the manufacturer's best-mix recommendations.

Difficulty starting: If the engine is having difficulty starting, make sure the LPG tank valve is open and there are no obstructions in the fuel line. Check the ignition system, including the spark plugs and wires, for any problems.

Fuel leaks: If you smell gas or see signs of a leak, immediately close the LPG tank valve and check all connections for tightness and damage. Repair or replace any damaged parts before resuming operation.

Inconsistent Fuel Supply: If the engine is experiencing intermittent fuel supply issues, BISON considers it necessary to check that the LPG regulator is functioning properly and that the carburetor is heating the LPG as required. Replace any failed components as necessary.
