System Overview
The cold test checks the functioning of the mechanical engine components. Mainly these are crank mechanism, valve train and lubricating system. Today it is also possible to check the ignition system, the injection system, the wiring harness as well as the sensors and actuators. By measuring the sequence of various signals such as intake depression, exhaust back pressure, turnover torque it is possible to form conclusions on the mechanical integrity.
