Abstract

The invention provides an air cleaner for an engine, belonging to the technical field of vehicle air purification. The air cleaner comprises an air blower, a main air filtrating screen, a subsidiary air filtrating screen and an air outlet. A shell of the air blower is provided with an air inlet and an air outlet; the main air filtrating screen is connected on the shell of the air blower directly or through a main body, or the main air filtrating screen and the subsidiary air filtrating screen are connected on the shell of the air blower together through the same main body; the main air filtrating screen is connected on the main body directly or through a main body air inlet cavity; the subsidiary air filtrating screen is connected on the main body directly or through a main body air outlet cavity; and the air outlet is positioned in the subsidiary air filtrating screen or the main body air outlet cavity. The air cleaner for the engine increases pressure through the air blower, and is in parallel connection with an original natural air inlet system to operate; the air inflow of the engine is increased; under the condition of guaranteeing safety and reducing energy consumption, the pollution is relieved, and the engine output power is increased.

Description

technical field [0001] The invention relates to the technical field of vehicle air purification, in particular to an engine air filter. Background technique [0002] The existing air intake air filter for the engine engine is a natural air intake structure. Air is drawn into the engine cylinders by creating a pressure differential between atmospheric pressure and engine suction. [0003] The disadvantages of the natural intake air filter are: insufficient air intake, especially when the engine is running at high speed, the intake air flow increases, and the resistance of the filter screen increases with the increase of air flow, resulting in insufficient air supply, reduced engine efficiency, and exhaust gas serious pollution. [0004] The disadvantages of turbocharged air filter and exhaust gas driven turbocharged are: the engine temperature is high, there is a risk of spontaneous combustion, and the low speed effect is not obvious. [0005] The disadvantage of the exist...
