Abstract

The invention relates to an apparatus and method for correction of intake pulsation. The method for correction of intake pulsation is provided. The method includes calculating a basic air charge amount of a cylinder or a charge amount conversion coefficient based on a measurement value of a sensor disposed in an intake system of an engine. A basic pulsation compensation coefficient for correctingan intake amount from a basic waveform of pulsation is calculated based on opening / closing of an intake valve and engine RPM. The basic pulsation compensation coefficient is then corrected when the basic waveform of the pulsation is changed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0119416 filed on September 18, 2017, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a device and method for correcting intake pulsation, and more particularly, the present invention relates to a method for compensating intake pulsation generated in an intake system of an engine of a vehicle according to factors affecting intake pulsation Apparatus and methods. Background technique [0004] The air intake of a car engine should be accurately calculated to improve the performance and fuel efficiency of the engine. In addition, the intake air volume of the automobile engine is also an important factor in determining the composition of the exhaust gas. Specifically, fuel is injected into the gasoline engine according to the intake air volume of the engine to perform the...
