Cat ® C32 <strong>Marine</strong> Propulsion Engine Provides Quick Acceleration and<br />
High Reserve Power, with Less Weight and Space<br />
<strong>Caterpillar</strong> <strong>Marine</strong> Power Systems announces the C32 marine propulsion engine, which<br />
provides quick acceleration and high reserve power, with a relatively small footprint and<br />
light weight. The engine’s light weight meets requirements for crew boats and other<br />
marine applications where lower weight can be directly translated into fuel savings and<br />
increased dollars.<br />
With a high displacement (32.1 liters), the C32 delivers outstanding levels of torque,<br />
providing noticeably better acceleration than its commonly used predecessors: the Cat<br />
C30 and 3412E engines. This fast acceleration is especially well suited for pleasure craft,<br />
lobster boats and patrol craft. Other applications include workboats, fishing boats,<br />
commercial utility vessels and tugs.<br />
The C32 employs the most advanced fuel system on the market today – <strong>Caterpillar</strong>’s<br />
patented HEUI (Hydraulically actuated, Electronically controlled, Unit Injector) fuel<br />
system. The C32 is configured as a V-12, twin turbocharged and aftercooled engine.<br />
Modeled after the durable and reliable Cat 3412 engine, the C32 features a HEUI fuel<br />
system that maintains high injection pressures across a broad range of rpms and<br />
guarantees maximum fuel efficiency. Fuel consumption at the engine’s maximum rated<br />
speed is 327 L/hr (86.4 gal/hr). See Table 1.<br />
The C32 is IMO, EPA and EU compliant and features low emissions, with virtually no<br />
smoke or soot.
The C32 has a flat power curve between its vessel cruising speed of 1900 rpm and its<br />
maximum speed of 2300 rpm. This power band allows the engine to draw on reserve<br />
power for easy acceleration.<br />
Comparing maximum power outputs at 2300 rpm, the C32 delivers 7 percent more power<br />
than the C30 and 18 percent more power than the 3412E. Yet, the C32 is similar in size<br />
and weight due to its “V” block design, which provides for a compact engine package.<br />
Pleasure and selected commercial marine applications benefit from this compact design<br />
as well as the engine’s power-to-weight ratio of 1.52 kg/mhp (3.4 lb/bhp).<br />
Requiring no sequential turbochargers or high-pressure fuel pumps, the Cat C32 is easier<br />
to service and less complex than many alternative engines. Its new Electronic Control<br />
Module (ECM) gives the engine superior levels of control, monitoring, and data input<br />
and output capabilities. Faster processing capabilities of the ECM allow for the addition<br />
of multiple inputs and outputs for future enhancements.<br />
The C32 features a two-piece forged steel piston designed for extended wear and capable<br />
of handling engine firing pressures without damage. The engine’s crosshatched hardened<br />
liners feature longer life due to better oil retention on the liners, and its through hardened<br />
crankshafts withstand higher cylinder pressures for longer life.<br />
It is available in both keel cooled and heat exchanger cooling options and can be fully<br />
integrated with <strong>Caterpillar</strong>’s Engine Vision Display (EVD), <strong>Marine</strong> Power Display<br />
(MPD), <strong>Marine</strong> Analog Power Display (MAPD) and Multi-Station Control System<br />
(MSCS).<br />
