With direct injection and choice of natural aspiration or turbocharging, the B3.3 offers outstanding levels of power output and fuel efficiency. With the B3.3 you can be sure of a proven design built to the very highest Cummins specifications. And high power comes without a fuel penalty, due to a highly efficient direct injection system. Peak torque is available at just 1600 rpm. More strength less noise Parent bore block with deep, stiff crankcase and optimised rib arrangement with an isolated valve cover provide enhanced strength and lower noise.
Optional pack can reduce noise even further.
Quick start Direct injection and distributor pump with integral timing advance means quicker starting, particularly when cold. Intake air heater option is also available for exceptionally low temperature starting. More uptime Simple, robust design with fewer parts ensures less maintenance and single side service option is available. Cross flow cylinder head ensures even temperature distribution and water cooled design offers maximum efficiency under harsh operating conditions. Even with the high performance output of the B3.3, oil change intervals are increased to 750 hours for the naturally aspirated and 375 hours for the turbocharged version.
