2004 Engines Preview
|Diesels: Volvo Penta|
Volvo Penta has three new engines for 2004: the 130 and 160 hp D3 inboards for smaller applications, the D4 DuoProp, and the D6 DuoProp; all three meet 2006 emissions standards.
The lightweight (683 pounds), all-aluminum D3 is a five-cylinder engine that features vertical dual-inlet manifolds, electronic controls, common-rail fuel injection, and a variable-geometry turbocharger that generates output as needed, enhancing acceleration, performance, and fuel efficiency. Volvo Penta claims that the engine’s performance is actually better than that of a four-stroke outboard and that no other diesel compares with it. It comes in two power ratings: 130 and 160 hp.
The four-cylinder D4 and six-cylinder D6 in-line diesels feature Electronic Vessel Control (EVC), which integrates engine control, instruments, and accessories into one system, and Volvo Penta’s common-rail fuel-injection system, which increases performance and fuel efficiency while reducing emissions and noise. Both engines are compact; the D4 measures 36.7"x29.9"x30.7", with an output of 210 hp and a maximum rpm of 3500. In terms of performance, the company says the “D4 is similar to a V-6 gasoline-powered engine, while the external dimension is comparable to a V-8.” The larger and more powerful D6 measures 46"x29.9"x30.7" and has a 310-hp output at a maximum rpm of 3500.
Both are available with DuoProp drive or as inboards with hydraulic transmissions.
