High/low temperatures coolant circuits
Thermostatically controlled coolant with separate pumps for high and low tempera-ture coolant.
Individual supply of each cylinder unit via distribution channels cast into the crank-case.
Pistons are cooled by the engine lubricating system. Each piston is supplied with oil by piston
cooling jets.
Fuel filters
Depending on requirements, several filters combinations such as prefilter unit or working filter
ensure the fuel conditioning.
Therefore a high contamination retention capacity between tank and engine is ensured.
Injection system
The high pressure fuel system is supplied by a high pressure pump.
The low pressure system is supplied by the fuel pre-feed pump which ensures the circulation from
the tank and pre-feeds the high pressure system.
The high pressure system leads the pressurized fuel from high pressure pump to the injectors.
The high pressure system is secured by a pressure control valve.
