Engine air inlet system with continuously variable air inlet resistance, engine air inlet adjusting method and engine

Abstract

The invention discloses an engine air inlet system with continuously variable air inlet resistance, an engine air inlet adjusting method and an engine. The system comprises a fixed air outlet pipe and a moving air outlet pipe capable of moving relative to the fixed air outlet pipe; the fixed air outlet pipe is fixed on an air inlet component of the engine; the moving air outlet pipe is mounted in the air inlet component; and an operating mechanism is arranged on the moving air outlet pipe and can control the moving air outlet pipe to move, so that the moving air outlet pipe makes contact with and is connected with the fixed air outlet pipe and is gradually separated from the fixed air outlet pipe. With the engine air inlet system with the continuously variable air inlet resistance, the engine air inlet adjusting method and the engine, smooth torque output is realized, the air inlet resistance has the relatively large change range and is fast in response relative to the displacement of the moving air outlet pipe, the action distance is short, and the requirement for arrangement space is not high.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine intake system with continuously variable intake resistance, an engine intake adjustment method and an engine. Background technique [0002] When the engine is working at a low speed, an intake system with a large intake resistance is required, while at a high speed, an intake system with a small intake resistance is required. The traditional engine variable intake system has two forms: one is to set up two intake systems, and realize the switching of the two intake systems by changing the two position states of the valves. The low speed adopts the long intake passage, and the high speed adopts the The short intake channel, however, adopts the "switching" method, which is not a continuously changing variable intake system, and the torque output is not smooth; The total length, its variable length is equal to the movement distance of the operating mechanism, and the inta...

The traditional engine variable intake system has two forms: one is to set up two intake systems, and realize the switching of the two intake systems by changing the two position states of the valves. The low speed adopts the long intake passage, and the high speed adopts the The short intake channel, however, adopts the "switching" method, which is not a continuously changing variable intake system, and the torque output is not smooth; The total length, its variable length is equal to the movement distance of the operating mechanism, and the intake resistance is linearly related to the movement distance. In a limited space, the variable range of the intake resistance is small, and the intake resistance is relatively small compared to the Slow displacement response
