Eccentric swing impeller engine air intake pressurizer

Abstract

The invention discloses an eccentric swing impeller engine air intake pressurizer. The pressurizer can improve air intake efficiency of an engine, correspondingly improves output power of the engine and reduces fuel consumption. The pressurizer mainly comprises a driving mechanism, a swing impeller rail chamber, an eccentric swing impeller air squeezing pressurization cavity and a pressure release valve. A belt wheel at the front end of an engine crankshaft rotates, the driving mechanism is driven by a belt to drive an impeller shaft which is located inside the eccentric swing impeller air squeezing pressurization cavity and eccentrically installed in a cavity sleeve to rotate, when the impeller shaft rotates and drives swing impellers to rotate and to be unfolded, intake air filtered by an air filter is sucked into, when the swing impellers are folded, intake air for pressurization is squeezed out, and unfolding and folding of the swing impellers are controlled by swing rail arms inside the swing impeller rail chamber according to rail rotation in a linkage mode; the pressure release valve directly release air pressure higher than the rule, so that it is guaranteed that air pressure of intake air is smooth and steady; the eccentric swing impeller engine air intake pressurizer is installed on the engine, requirement space is little, convenience is achieved, and performance is not influenced by high temperature and the like and is quite stable.

Description

Technical field: [0001] The invention specifically relates to an eccentric swing vane engine intake supercharger, which belongs to the technical field of engine intake. Background technique: [0002] Supercharging the intake air of the engine improves the intake efficiency of the engine, and the output power of the corresponding engine is also greatly increased. In particular, the working speed does not need to be too high, and the pulley at the front end of the engine crankshaft is driven and installed by a belt. An eccentric swing vane engine intake supercharger that requires small space, is convenient and has stable performance. At present, the air intake of most engines is naturally aspirated, and some engines are equipped with exhaust gas turbochargers. Naturally aspirated means that when the engine is in the inhalation process, the intake air is naturally inhaled under the negative pressure and pressure difference generated by the downward movement of the engine pisto...

AI Technical Summary

Problems solved by technology

Naturally aspirated means that when the engine is in the inhalation process, the intake air is naturally inhaled under the negative pressure and pressure difference generated by the downward movement of the engine piston, so that the intake efficiency of the engine is limited and cannot be improved, and the output power of the corresponding engine is also reduced. Not getting higher fuel consumption increases

Although the exhaust gas turbo intake supercharger supercharges the intake air of the engine, so that the intake efficiency of the engine is improved, and the output power of the engine is increased accordingly, and the fuel consumption is reduced, but because the working speed is too high, it needs to be driven by the exhaust gas of the engine, and The installation of the supercharger is limited due to the complex structure of the exhaust gas exhaust pipe of the engine; due to the high temperature of the exhaust gas, the intake air temperature is high, and the intake air cooler is required to cool the intake air; the installation space is too large; the high temperature of the exhaust gas also affects the exhaust gas turbine. The service life of the intake supercharger oil seal copper sleeve and other components leads to unstable performance; the exhaust gas turbo intake supercharger can only be driven when the engine reaches a certain speed, and the intake pressure exceeds the specified value when the intake air is boosted. Stop the turbine rotation to reduce the intake pressure, making the boosted intake pressure unstable
