The 188F multi-fuel carburettor is a fuel switching system designed for medium-displacement engines for a wide range of medium-sized equipment, such as standby generators, large water pumps or machinery on construction sites. This carburetor allows the engine the flexibility to switch between petrol, liquefied petroleum gas (LPG) and natural gas (NG) depending on availability and cost-effectiveness. For the 188F, the ‘188’ identifies the model of the engine, which typically represents a displacement of approximately 389cc to 420cc. This carburettor is designed for GX390, GX420 and corresponding 8HP to 9HP engines that fit into this displacement range, with applicable power from 2 kW to 6.5 kW. Not only does this provide versatility in fuel usage and help reduce daily running costs, but the choice of the 188F multi-fuel carburettor is an ideal solution for those seeking to reduce their environmental impact and improve engine suitability.

A 168F multi-fuel carburettor usually refers to a device for switching fuel types such as petrol, natural gas or liquefied petroleum gas (LPG) for use in small engines such as small generators, water pumps or engines for agricultural machinery. This type of engine is usually identified by its displacement, and in the case of the 168F, ‘168’ usually refers to an engine displacement of 163cc.

The 188F carburetor set can be equipped with a GX390 generator set. Such units typically include gasoline engines, generators, 188F carburetors, and other related accessories and components. As the core component of the engine fuel system, the carburetor is responsible for mixing gasoline and air in a certain proportion to form a combustible mixture to supply the engine to burn and do work.

Diaphragm carburetor is a special type of carburetor, its main feature is the use of diaphragm structure to control and regulate the mixing degree of fuel and air. This type of carburetor is usually used in small engines, such as chainsaws, lawn mowers, etc., and some specific working environments, such as equipment that needs to work in a tilt or flip state.

The 188F series cylinder heads match GX390 engines, GX420 engines and GX460 engines. The essential difference is capacity. The cylinder head is made of gray cast iron or alloy cast iron, but in recent years, because aluminum alloy has good thermal conductivity and can improve the compression ratio, the use of aluminum alloy cylinder head is more and more widespread. As a part of the combustion chamber, the shape of the cylinder head has an important impact on the work of the engine. Because of the different combustion modes of gasoline engine and diesel engine, the parts of the combustion chamber on the cylinder head are also very different.

The 120F cylinder head and cylinder body together constitute the combustion space, and are equipped with inlet and exhaust valve seats and valve guide holes for the installation of inlet and exhaust valves. The 120F cylinder head also has a cooling water channel to cool the high-temperature gas. In addition, for multi-cylinder engines, the 120F cylinder head must be separated from the combustion chamber of the adjacent cylinder to prevent air leakage or cross-fire.

The cylinder head, also known as the cylinder head, is an important part of the engine. It is located in the upper part of the cylinder block, and plays the role of sealing the cylinder and forming the combustion chamber. Due to the high temperature and high pressure gas, the cylinder head bears a huge thermal load and mechanical load. For water-cooled engines, there is usually a cooling water jacket inside the cylinder head to cool high-temperature parts such as the combustion chamber by circulating water.

The 168F cylinder head series has three products, which are 5.5HP cylinder head, 6.5PH cylinder head and 170F cylinder head, and the difference is essentially the capacity.

Diaphragm carburetor is a special type of carburetor, its main feature is the use of diaphragm structure to control and regulate the mixing degree of fuel and air. This type of carburetor is usually used in small engines, such as chainsaws, lawn mowers, etc., and some specific working environments, such as equipment that needs to work in a tilt or flip state.

Pump carburetor, as the name suggests, is a carburetor adapted to the pump engine. When using and maintaining the 168 carburetor, it is necessary to follow certain operating specifications and precautions to ensure its normal work and extend its service life. For example, the filter screen or filter element needs to be cleaned and replaced regularly to prevent impurities and metal particles from entering the carburetor; Need to check the oil level and oil quality regularly to ensure the stability and quality of fuel supply; It is necessary to avoid long idling or high load operation to prevent overheating or damage to the carburetor.
