TA

Optimal combustion and reduced emissions: the C9.3 propulsion, auxiliary and generator engines stand out for having a common rail fuel system. They are equipped with optionally available cooling systems for the propulsion and auxiliary engines which include heat exchanger with seawater cooling and keel cooling with aftercooler with combined circuit or separate circuit. The generator sets are available with heat exchanger, keel cooling or radiator. These auxiliary engines meet EPA Tier 3 and IMO II emissions standards. The ratings of the propulsion engines are EU Stage IIIA certified, while the generator sets are CCNR Stage II certified.

Why Choosing It

Electronic control system

 

While maintaining fuel efficiency at high engine speeds, the electronic control system provides industry-leading low-rpm torque and acceleration response.

 

Common rail fuel system

 

The C9.3 auxiliary engines are equipped with a common rail fuel system that allows optimal combustion and offers reduced emissions.

 

Positions left and right

RH and LH service positions for fuel and oil filters and dipstick improve ease of maintenance.

 

Compatibility

 

Compatible with Cat® displays.

 

Remote control

 

Remotely mounted display panels available as an option with start/stop functions and engine diagnostics.

 

Electrical Advantages

 

12 V or 24 V electrical system

 

Certificates

 

MCS (Marine Classification Society) certificates: ABS, BV, CCS, CRS, DNV, GL, IRS, KR, LR, NK, PRS, RINA, RS.
