Pneumatic energy storage turbocharger

Abstract

The invention relates to a gas-pressure energy-storage type turbocharger. The gas-pressure energy-storage type turbocharger comprises a turbocharger body and a gas storage chamber. The gas output end of the turbocharger body is communicated with a gas cylinder through a gas inlet pipeline, the gas storage chamber is communicated with the gas inlet pipeline through a first valve, and the first valve is used for controlling connection between the gas storage chamber and the gas inlet pipeline. The gas storage chamber can store high-pressure gas generated when an automobile decreases speed, the high-pressure gas is fed back into the gas inlet pipeline when the automobile is accelerated, in this way, the turbo lag is relieved, fuel waste is reduced, and the gas-pressure energy-storage type turbocharger saves energy, reduces emissions, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of engine combustion and emission, and relates to a pneumatic energy storage type turbocharging device. Background technique [0002] Since the car supercharger can increase the output power of the engine, the car supercharger is becoming more and more popular in today's market. At present, there are three kinds of automobile superchargers, exhaust gas turbocharger, mechanical supercharger and mechanical exhaust gas turbo double supercharger. [0003] The traditional exhaust gas turbocharger is powered by the exhaust gas of the engine, which does not increase energy consumption, but has a turbo hysteresis effect, which not only affects the driving experience of the driver, but also causes insufficient fuel combustion and increases pollutant emissions; mechanical The power of the supercharger is provided by the engine, which can be boosted synchronously with the engine. Although the hysteresis effect is well...

Problems solved by technology

[0003] The traditional exhaust gas turbocharger is powered by the exhaust gas of the engine, which does not increase energy consumption, but has a turbo hysteresis effect, which not only affects the driving experience of the driver, but also causes insufficient fuel combustion and increases pollutant emissions; mechanical The power of the supercharger is provided by the engine, which can be supercharged synchronously with the engine. Although the hysteresis effect is well solved, it will waste the engine output power and increase fuel consumption. The acceleration effect at high speed is insufficient; the mechanical exhaust gas turbo double supercharge The supercharger can effectively make up for the shortcomings of the above two superchargers, but the structure is complex, it takes up a lot of space, and the cost is high, so it is difficult to popularize
