2003 Engines Preview
Caterpillar says its newest engines, the C18 and the C30, were designed for smooth, fast acceleration. The electronically controlled C18 is Caterpillar's most powerful in-line six to date, with the lowest weight-to-horsepower ratio of any other Cat marine engine, making it ideal for fast, planing hull designs. The state-of-the-art ADEM III electronic control module enhances performance with nearly eight times as much memory, twice the input/output capacity, and a significantly faster processing speed than what was previously available. "These improvements increase engine control, monitoring capabilities, and provide reserve capacity for future enhancements such as multistation controls, optional gauges, and enhanced customer diagnostic capabilities," says Caterpillar. Two engine ratings are available for the C18: 1,000 hp at 2300 rpm, and 875 hp at 2200 rpm.
The C30 is the same size as the popular Cat 3412E but features an additional 148 hp, giving it a top rating of 1,550 hp at 2300 rpm. It is also equipped with the ADEM II ECM and Caterpillar's patented HEUI fuel system, which reportedly maximizes power and torque while offering excellent fuel economy and meeting current emissions standards. This combination not only provides high-performance engine control, but the ADEM II ECM can synchronize up to three engines and offers customer-specified parameters, such as programmable idle speed, trolling mode, and a slow-vessel mode for docking.
Both the C18 and the C30 will receive a new, high-quality, two-layer polyurethane paint, with custom colors and polished castings as options. Both engines are covered by a two-year warranty with an extended five-year warranty on major components and backed by 24-hour worldwide technical support. Phone: (309) 578-6298. www.cat.com.
