Abstract

The system has an intake manifold (200) comprising a runner, and an opening / closing part (340) for varying runner length of the intake manifold. An actuator drives the opening / closing part, and a vacuum part forms a vacuum chamber to drive the actuator. The vacuum part is disposed on an upper portion of the intake manifold such that noise from the engine is decreased. A cover is disposed on an opening portion of a body.

Description

technical field [0001] Generally, the present invention relates to vehicle engines. More specifically, the present invention relates to adjustable roll-in systems for vehicles. Background technique [0002] Typically, there are several types of vehicle engines. Among them, the engine with an adjustable intake system can change the effective length of the intake manifold flow path according to the driving conditions of the vehicle, and the research on the adjustable intake system is still going on. [0003] As we all know, the adjustable intake system can change the effective length of the intake manifold flow path, which usually includes: a throttle body; a compression chamber connected with the throttle body; an intake manifold, which has multiple A flow path of air; a passing member placed on a predetermined portion of the intake manifold; an opening / closing member that can open and close the passing member according to vehicle driving conditions (eg, vehicle running spe...
