Combustion Pressure Monitoring System

1. Main functions

Measurement durability of parts for engine units by checking exact engine combustion condition
Raising availability and reliability of engine and reducing maintenance cost
Providing the following information through combustion pressure monitoring for all cylinders
· Check of oil leak at a cylinder by monitoring combustion chamber pressure
· Check of Abnormal increase of cylinder pressure or knocking of compression pressure by carbon, etc.
· Detection Malfunctions of injection system at a cylinder
· Real-time monitoring information for engine operation condition
Combustion Pressure Monitoring System

2. Features

Design of Integrated CPMS
· Reduced inductance between wires and conducted-noise thanks to less wiring
· Easy to install, move, and maintenance , economically-feasible and expandable
Independent AMP Module (A/D Converter-mounted) installed for each cylinder
· Easy maintenance and economic feasibility; only need to change the individual module unit for the problem cylinder when a problem occurs
· Independently processing and sending pressure signals from the individual cylinder
include Simultaneous calibration function of pressure sensor and AMP Unit
· High maintainability owing to the improved accuracy in measuring pressure and cartridge-type products used
include Simultaneous calibration function of pressure sensor and AMP Unit
· High maintainability owing to the improved accuracy in measuring pressure and cartridge-type products used
Equipped with temperature compensation circuit (minimizing AMP signal drifts caused by changes in temperatures)
AMP self-diagnosis functions
· Gaining individual AMP and correcting inconsistencies in A/D converter
· Generating reference signals at integrated CPMS regularly to check inconsistencies in AMP; setting off the alarm when error margin was exceeded.
Knocking-detection algorithm design applied
