Engine monitoring system The engines are equipped with common rail system and electronically controlled injectors. The injectors contain an electro-magnetic valve which sets the amount of fuel injected and the correct timing. The monitoring system measures the charge air pressure and temperature, and calculates the available air mass. This determines the maximum amount of fuel that can be injected (smoke limiter function).

To protect the engine at too high coolant or charge air temperatures and boost pressure as well as oil pressure, the monitoring system reduces the amount of fuel (reduced engine output) until the current values are normalized. The engine monitoring system also has a diagnostic system, which helps users and service technicians to determine the cause of any malfunctions in the system quickly by using the or a diagnostic tool.
Diagnostics
Engine speed
The system also limits the maximum torque available at the engine speed registered to protect the engine and transmission from overload.

Any fault is shown on the EVC system tachometer/ EVC system display and the VODIA diagnostic scan tool. The diagnostic tool supports in several languages.
