Caterpillar's Engine Products Division has introduced the availability of a new, totally electronic 3412E marine diesel engine with ratings from 503 to 1,400-bhp (375-1,044-bkW) for commercial marine application.
As compared to previous Cat 3412C engines, 3412E has upgraded horsepower, improved emissions control and enhanced midrange performance - with faster acceleration and improved cruising characteristics. The engine's superior reserved power enables it to respond quickly to increased load caused by adverse conditions such as swift currents, loaded nets and hard turns.
Test engines rated at 624-bhp (465-bkW) at 1,800 rpm are offering stellar results in two 70 ft. (21.3 m) twin-screw inland waterway tow boats - allowing for improved trip times. Compared to the 3412C, the upgraded engine provides the same strong 27-liter displacement, 12 cylinder vee, 4-stroke cycle diesel with the additional new electronic control and fuel systems
, turbochargers and pistons.
