Problems solved by technology

However, if the combustion pressure sensor is installed on only one engine cylinder, the data of the engine cylinder without the combustion pressure sensor may not be detected
On the other hand, if combustion pressure sensors were installed on all engine cylinders, the cost could increase significantly

Abstract

Disclosed are a method and an apparatus of detecting a combustion phase of an engine by an angular acceleration signal and combustion data of a single cylinder. The method may include calculating a point of maximum angular acceleration of each engine cylinder during an explosion stroke, detecting a combustion phase of an engine cylinder provided with a combustion pressure sensor, calculating a time difference between the point of maximum angular acceleration and the combustion phase of the engine cylinder provided with the combustion pressure sensor, and determining a combustion phase of an engine cylinder where the combustion pressure sensor is not mounted by using the time difference and the point of maximum angular acceleration of the engine cylinder where the combustion pressure sensor is not mounted.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2013-0150694 filed on Dec. 05, 2013, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a method and a device for detecting the combustion phase (COMBUSTION PHASE) of an engine through angular acceleration signals and combustion data of a single cylinder. More particularly, the present invention relates to a method and apparatus for detecting the combustion phase of an engine cylinder by using a combustion pressure signal and an angular acceleration signal of an engine cylinder having a combustion pressure sensor mounted thereon to detect combustion phase without a combustion pressure sensor Combustion phases of engine cylinders. Background technique [0004] Internal combustion engines that convert thermal energy generated by fuel combustion into mechanical energy c...
