Motor vehicle internal combustion engine speed-sensitive linear automatic supercharging air supply device

Abstract

The invention provides a motor vehicle internal combustion engine speed-sensitive linear automatic supercharging air supply device. The air supply device is provided with a supercharging chamber communicating with an air inlet pipe of an internal combustion engine. An air inlet of the supercharging chamber faces against the wind generated by a motor vehicle during advancing, and the air pressure in the supercharging chamber and the air supply amount of the internal combustion engine are automatically increased and reduced along with change of the vehicle speed. The supercharging chamber can beof a combined structure, or an eggshell type structure, a whistle type structure, or a horn type structure or a straight pipe type structure. The combined supercharging chamber is composed of a supercharging chamber body and an auxiliary supercharging chamber body on the upper portion. A valve grid is arranged between the supercharging chamber body and the auxiliary supercharging chamber body. Anair pressure valve is arranged on the valve grid and is limited between guide rods to float up and down. The upper end of the auxiliary supercharging chamber body is provided with an auxiliary air inlet used for being sealed when the air pressure valve floats up. An internal combustion engine air inlet pipe communicates with the auxiliary supercharging chamber body. A pipe serves as the air inletand goes into the supercharging chamber body in the tangential direction. Air is fed into the internal combustion engine through the wind pressure generated by the motor vehicle during running to increase the air supply amount and promote sufficient burning of fuel oil. The power of the internal combustion engine is increased. Oil consumption is reduced. Carbon deposit of the internal combustionengine is reduced. The purchase cost and the maintenance cost of the motor vehicle are reduced.

Description

technical field [0001] The invention belongs to a fuel-saving and efficiency-enhancing device, in particular to a speed-dependent linear self-supercharging air supply device for a motor vehicle internal combustion engine. Background technique [0002] If the air intake of the motor vehicle internal combustion engine is sufficient, the fuel combustion is sufficient. As the speed of motor vehicles increases, the power of the internal combustion engine is required to increase accordingly. The speed of the internal combustion engine increases the intake air volume or the oil supply volume needs to be increased accordingly. The naturally aspirated internal combustion engine relies on the speed to increase to generate a higher negative pressure to inhale and supply oxygen. The longer the intake passage, the higher the speed, the higher the negative pressure, and the greater the resistance when the air flows through the air passage, resulting in a lag in air supply instead of a l...

AI Technical Summary

Problems solved by technology

The mechanical supercharging method not only consumes a lot of fuel, but also increases the cost of the motor vehicle and the maintenance cost; the cost of the motor vehicle increased by adding a gas exhaust turbocharger is about 10,000 yuan, and it also increases the subsequent maintenance cost

Since the entire air supply channel of the turbocharger, together with the cooling system, has a total path of two or three meters, the diameter is thin, and the path is not smooth and smooth, so the entire air supply is not smooth before the supercharging intervenes.
