In order for an engine to run smoothly and efficiently, the combustion
chamber must be free of leakage. An
engine with low compression in one or more cylinders is inefficient and will run
rough or lack in performance.
Low compression may or may not cause the MIL to illuminate.
Low compression ca
The boost pressure of the turbochargers is directly dependent on the flow of
exhaust gas which reaches the
turbocharger turbines. Both the velocity and the mass of the exhaust-gas flow
are directly dependent on engine
speed and engine load.
The engine-management system uses wastegate valves to co
