16V 4000 M73L

Widely used on naval vessels such as corvettes and frigates, the 16V 4000 M73L is a robust and versatile engine designed to meet stringent maritime demands. This powerful 4-stroke diesel engine from the Series 4000 family offers a maximum continuous rated power of 2720 kW at 2100 rpm, making it suitable for both propulsion and generator applications. The engine’s high power density is complemented by its common rail injection system, which ensures efficient fuel delivery and performance. With bore and stroke dimensions of 170 mm and 190 mm respectively, the 16V 4000 M73L is built to withstand the harsh marine environment. The 16V 4000 M73L is compliant with IMO Tier II emissions standards and can operate on a variety of fuels, including Marine Diesel Oil (MDO) and Marine Gas Oil (MGO). It features sequential turbocharging with two water-cooled turbos, enhancing its performance and reliability. Despite its robust design, common issues that may arise include raw water pump seal failures leading to saltwater corrosion, and fuel contamination causing damage to the high-pressure common rail injection system. Regular maintenance is crucial to prevent these issues and ensure optimal operation of the 16V 4000 M73L.
