Intake-air control system of the automobile engine has been improved for fuel economy and low emission. The electronically controlled throttle spreads, and the variable intake valve is being attempted to apply more. This study is to find the control indices for raising the charging efficiency of the cylinder. As a candidate of the control indices, the intake-air pulsation, namely resonant vibration, was extracted by the simulation using GT-POWER* which is the general-purpose model of the engine. In continuing, the experiment with 4-cylinders engine that the pressure sensors were installed in air flow line is carried out. The pressure pulsation which generated in the inlet port and propagated to the manifold against the air flow, was able to be detected successively. * trademark of CD-adapco Co. Ltd
