Pressurization air filter for four-cylinder four-stroke generator

Abstract

The invention discloses a pressurization air filter for a four-cylinder four-stroke generator. The pressurization air filter comprises a main pipeline. The two ends of the main pipeline communicate with the outside world and an air inlet end of an engine correspondingly. An air pump is fixed to the middle of the main pipeline. The side, close to the engine, of the main pipeline is divided into a first air purification cavity and a second air purification cavity. The other end of the main pipeline is divided into a first air inlet cavity and a second air inlet cavity. The first air purificationcavity, the second air purification cavity, the first air inlet cavity and the second air inlet cavity are each internally provided with a valve. The pressurization air filter has the advantages thatthe air pump pumps air from the air inlet cavities to the outside world and injects air into the air purification cavities, at the same moment, an air inlet door of only one cylinder of the engine isopened, while the air pumping quantity of the air pump is larger than the air suction quantity of the single cylinder, thus pressurization can be generated on the engine, the effect that sufficient oxygen can enter the cylinder of the engine is ensured, sufficient burning of fuel oil is facilitated, and the purposes that power performance of the engine is improved, specific power is improved, fuel economy is improved, and exhaust emission and noise are reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle engines, in particular to a booster filter device for a four-cylinder four-stroke generator. Background technique [0002] The engine is the most important part of the car. During the working process of the engine, when the intake valve of the cylinder is opened, it will generate negative pressure and inhale outward, but the negative pressure inhalation cannot inhale enough gas, so it is difficult to ensure the combustion of fuel in the cylinder Sufficiently, the engine supercharging methods in the prior art include two kinds of turbocharging and supercharging, and the effect of supercharging is better than that of turbocharging. Too much is pressed into the engine, and the engine must inhale the clean gas filtered by the air filter. The existing supercharging method does not have the effect of cleaning the air filter part of the engine, resulting in a shorter service life of the engine air filter...

[0002] The engine is the most important part of the car. During the working process of the engine, when the intake valve of the cylinder is opened, it will generate negative pressure and inhale outward, but the negative pressure inhalation cannot inhale enough gas, so it is difficult to ensure the combustion of fuel in the cylinder Sufficiently, the engine supercharging methods in the prior art include two kinds of turbocharging and supercharging, and the effect of supercharging is better than that of turbocharging. Too much is pressed into the engine, and the engine must inhale the clean gas filtered by the air filter. The existing supercharging method does not have the effect of cleaning the air filter part of the engine, resulting in a shorter service life of the engine air filter, especially When the vehicle is driven in a harsh environment, the life of the vehicle air filter will be greatly shortened. If the air filter cannot be cleaned or replaced in time, the vehicle will cause serious damage
