C7.1 TIER 3/IMO II
Key Specifications
Length
1095 mm
Height
891 mm
Minimum width
798 mm
The C7.1 TIER 3/IMO2 II propulsion engine stands out for its immediate response time and prompt acceleration. The electrical system can be 12 V or 24 V. The jacket water pump and the gear-driven sea water pump make it reliable like few others.
The valve train requires no maintenance with valve lash adjusters.
Its ease of use is evident: it is compatible with Caterpillar displays and electronic components; the fuel system is self-priming to always guarantee smooth starting.
Three reasons to choose it?
- Its common rail fuel system allows for optimal combustion with low levels of emissions and no visible smoke.
- Advanced electronic control lowers combustion noise levels.
- The crankcase ventilation system is closed to allow better cleaning of the engine room.
