Description

Technical Field

[0002] The cylinder of a car engine is an important component of the engine, and the compression ratio is an important performance parameter of the engine. From the theory of thermodynamics, it can be known that the compression ratio directly determines the thermal efficiency and emissions of the power machinery. The higher pressure and temperature in the cylinder provided by the high compression ratio at the beginning of combustion can achieve better atomization effect and help increase the propagation speed of the flame. At the same time, the high compression ratio will reduce the residual exhaust gas, which can also improve combustion and increase thermal efficiency.

[0048] The working principle of the engine cylinder structure is as follows: when in use, air enters the cylinder chamber 211 through the intake valve 220, so that air and oil enter the cylinder chamber 211, and as the steel crankshaft 280 rotates, it drives the steel connecting rod 270 to move up and down, and the steel connecting rod 270 drives the piston 260 to move up and down, squeezing the space in the cylinder chamber 211, and ignites through the spark plug 240, so that the oil is ignited and burned, and as the piston 260 moves up and down, it squeezes the space and drives the engine to work, and air is taken in through the dual intake valves 220, so that the oil is fully burned in the cylinder chamber 211, and works together through the exhaust valve 230, so that the water vapor and smoke after combustion are discharged through the smoke outlet, and the engine cylinder burns, so that the cylinder body 210 generates a lot of heat, and through The coolant in the wet air jacket cylinder 250 absorbs heat, so that the heat energy generated by the cylinder block 210 is absorbed by the coolant in the wet air jacket cylinder 250, thereby achieving a cooling effect. By configuring a cylinder head 290 for each cylinder block 210, the single cylinder head 290 has a sufficient cooling area to ensure sufficient cooling. When the cylinder is used, the temperature rises, and the temperature sensor 311 transmits a signal to the controller 330, so that the controller 330 controls the water pump 310 to pump water and send water, and the coolant is circulated into the cooling pipe 320 for cooling. The heat dissipation fins 321 of the cooling pipe 320 dissipate the heat. By turning on the fan 350, the fan 350 blows air to cool the cylinder head 290 of the cylinder block 210, thereby further achieving a cooling effect.
