HAMBURG, Germany -- Caterpillar Marine Power Systems has received DNV clean design notation for a number of high-speed marine engine families. The engines were developed to meet both DNV clean design, EU Stage III A Inland Waterway (EU 97/68/EC), and US EPA Tier 2 Commercial Marine (40 CFR 94) requirements.
The following products are now available with DNV clean design notation: 3500C propulsion, C32 ACERT propulsion and auxiliary, C18 ACERT propulsion, C12 ACERT propulsion, and C9 ACERT propulsion and auxiliary.
The engine families exceed the requirements of DNV clean design with a further NOx reduction of at least 15% on average. DNV clean design notation is also available for the latest generation of MaK medium-speed marine engines comprising M 20 C, M 32 C, M 43 C, and the new M 25 C.
