Volvo Penta Engines D3 Diesel Stern Drive

Volvo Penta engines D3 common rail marine diesel is completely new and comes in  four different horsepower ratings, ranging from 140 to 220 hp. The basic motor is based on a state of the art Volvo car engine, the 2.4 liter, five-cylinder aluminum block. The engine's piezoelectric injectors can cycle twice as often as magnetically triggered injectors, so short duration injections can  generate more easily ignited mixture flows. Also the circular side opening creates a cone-shaped stream of fuel droplet emanating from the top center of the combustion chamber that can  be timed to produce a charge of varying density.

True to its common rail genes, its very quiet and virtually smoke free. Advanced cross-flow cooling maintains an even engine temperature. Variable geometry turbo-charging builds big torque from very low rpm up to wide-open-throttle with a payoff of shorter time to plane and higher top speed. D3’s emissions meet the very stringent US EPA Tier 3 regulations, which will come into force in 2012.

Volvo Penta’s electronic vessel control platform (EVC) is standard and includes electronic shift and throttle. With EVC it's possible to have instrumentation, or complete helm stations, in up to four locations on board.

The propellers for the DPS are now available in a completely new model. Then new I-series blade has a patented design that makes it highly efficient. The propellers are made of high-strength aluminum, which is die-cast under extreme pressure. The result is propellers with thin yet strong blades. Performance is in the same class as propellers made of stainless steel.
