A gasoline engine is a machine that converts chemical energy into mechanical energy.
A gasoline engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually a process of working cycle. Simply put, it burns the fuel in the cylinder to generate kinetic energy to drive the reciprocating movement of the piston in the engine cylinder. Drive the connecting rod connected to the piston and the crank connected to the connecting rod to make a reciprocating circular motion around the center of the crankshaft to output power.
Gasoline engine is mainly composed of crank connecting rod mechanism, valve mechanism, driving mechanism, fuel supply system, cooling system, lubrication system, starting and ignition system.
1. Crank connecting rod mechanism: The function of the crank connecting rod mechanism is to convert the linear motion generated by the gas expansion work of the piston into the rotational motion of the crankshaft during the power stroke; while in other strokes (intake, compression, exhaust), The crank connecting rod mechanism performs the opposite task, which is to transmit the rotational force of the crankshaft to the piston to make the piston produce linear motion.
2. Valve mechanism: The function of the valve mechanism is to ensure that when the piston is in a certain position, the valve is opened and closed, so that the combustible mixture enters the cylinder and the exhaust gas is discharged out of the cylinder.
3. Drive mechanism: The function of the drive mechanism is to drive the valve mechanism, distributor, generator, water pump, oil pump and other parts.
4. Fuel supply system: The function of the fuel supply system is to form a combustible mixture of air and gasoline, and to distribute the mixture evenly to each cylinder according to the engine load, and to discharge the burned exhaust gas out of the cylinder.
5. Cooling system: The function of the cooling system is to cool the cylinder block, cylinder head, valve, piston and other parts in the engine that are in contact with high temperature gas to ensure that these parts are not damaged due to overheating, so that the engine works reliably.
6. Lubrication system: The function of the lubrication system is to ensure that the lubricating oil is continuously supplied to the friction pairs of the engine to reduce the wear and friction loss of the friction pairs and reduce their temperature.
7. Starting and ignition system: The function of the starting system is to start the engine. The function of the ignition system is to ensure that the combustible mixture in the cylinder is ignited at a certain moment.

In modern agriculture, irrigation is a key link to ensure the healthy growth of crops and increase yields. With the development of technology, agricultural machinery and equipment are constantly being upgraded to meet the demands of more efficient and environmentally friendly agricultural production. The Chongqing agricultural gasoline engine water pump, as an important irrigation tool, plays an irreplaceable role in rural areas due to its powerful pumping capacity and portability. The Chongqing agricultural gasoline engine water pump typically consists of two parts: a gasoline engine and a water pump. The gasoline engine serves as the power source, driving the water pump through a transmission device. The water pump uses the centrifugal force generated by the rotation of the impeller to draw water from the source and transport it to the fields through pipes. This equipment is not only compact, small in size, but also lightweight, making it easy to carry and move, which is very suitable for use in various situations such as fields, orchards, and vegetable plots. In practical applications, the agricultural gasoline engine water pump demonstrates many advantages. Its strong pumping capacity can quickly draw groundwater or river water into the fields to meet the irrigation needs of crops. This is undoubtedly a great boon for arid areas or farmland with scarce water resources. The gasoline engine, as the power source, features quick start and stable operation, allowing it to maintain normal work even under harsh weather conditions.
