Engine: Cat C18 ACERT 930hp

Building off years of success with the Cat C18 ACERT marine engine, Caterpillar Marine Power Systems is announcing an additional engine rating for the in line engine to expand the power range available for global customers. The 930mhp (685bkW) rating for the C18 ACERT propulsion engine provides best in class torque to maximize acceleration and speed. Along with the 1015 and 1150 mhp ratings currently offered on the C18 ACERT engine, the additional rating will meet current industry demand for high power and is one of several marine engines Caterpillar will bring to the market over the next few years. Backed by more than 80 years of engineering excellence, the C18 ACERT propulsion engine is an in line 6, four-stroke, 18.1-liter diesel engine, which is electronically governed, turbo-charged and after-cooled. With a smaller, narrower package, customers will notice the improved ease of service with more room between engines compared to the existing engine ratings. The smaller footprint will also open additional opportunities where hull space prevented the installation of a C18 ACERT engine. A crucial feature of the new engine rating is the best in class power and torque, which results in faster speeds, better acceleration, and overall class leading cruising performance. Another important benefit is an improvement in overall fuel economy compared to other engine packages. In fact, compared to the existing C18 ACERT ratings like the 1150 mhp engine, the new 930 mhp rating will increase fuel efficiency upwards of 25%, which will be well received by customers. Additionally, the C18 ACERT engine will continue to be compliant with all major global emissions regulations, including IMO, EPA Tier 2, and EU 94/25/EC Recreational Craft Directive. Along with the improvements to performance, power and torque, all Cat C18 ACERT marine engines come with an excellent standard warranty, available for up to ten years after initial purchase of the engine. In addition to the standard five year warranty, Extended Service Coverage can be purchased to extend the overall protection of the engine.

Engine: Cat C32 Acert 1925hp

Cat C-series, electronically-controlled, high-speed marine engines are recognised for their sustainable performance, combining high power, low emissions and state-of-the-art fuel consumption. At this year’s Miami International Boat Show, Caterpillar presented another high-performance rating for its C32 ACERT model used in pleasure craft applications. Produced to highest standards the Cat C32 ACERT is a vee-type, 12-cylinder, 4-stroke marine engine with 145 mm bore and 162 mm stroke displacing total 32.1 litres. With its new EPA Tier 2-compliant E-rating, this engine provides 1417 kW - 1925hp at 2,300 rpm. The new C32 ACERT rating with 1925hp is specifically designed for pleasure craft applications, has 15 percent more power than the former C32 version without ACERT technology. Introducing a smaller and more robust engine block, the C32 ACERT engine is designed to be particularly durable, reliable and fuel-efficient. It offers the latest Mechanically actuated Electronically controlled Unit Injection (MEUI) fuel system, Caterpillar’s latest ADEM A4 Electronic Control Unit ECU and responsive twin turbo-charging and after-cooling. In addition, maintenance and robustness have been improved for the C32 ACERT engines. All standard maintenance items are mounted on the service side for easy access. The gear-driven water pump is self-priming. A titanium plate heat exchanger with integrated fuel cooler offers extended durability. ADEM software, which precisely determines fuel delivery, air management and all other engine functions, has been modified for the increased power rating and EPA Tier 2-compliant emission levels. Multiple fuel injection inserts fuel into the combustion chamber in a series of accurately timed “micro bursts”. These features combine to provide lower specific fuel consumption, particularly at part load, and also reduce smoke and emissions while delivering reliable maximum power output. Improved performance from advanced Cat C-series engines not only means more power overall, but also better acceleration, more reserve and rated power available at a wider speed range. Needless to say for an engine with ACERT technology, the C32 ACERT operates virtually smoke free under steady-state operation as well as under acceleration.
