Combustion Pressure Monitoring System

Home > Product Information > 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
