该论文已在芬兰赫尔辛基举行的第28届CIMAC大会上发表。论文的版权归CIMAC所有。Off-Highway applications such as locomotives, mining trucks, inland waterway carriers, ferries or tug-boats are operated several thousand hours each year and require robust and cost efficient internal combustion engines. Today most of these applications are powered by diesel engines. But tightened emission regulations and limited oil reserves lead to more complex engines and higher costs. This leads to the question: are compressed (CNG) or liquefied (LNG) natural gas an alternative to diesel fuel? Looking at availability, infrastructure, costs and engine-out-emissions good arguments can be found to switch from Diesel to Gas in the future. The motivation is clear but the hurdles are high: availability of gas equipment (fuelling equipment, storage-tanks, engines), operational experience with gas (fuelling, servicing) or clear regulations. Within this paper we will provide a first more deep insight into the development of a 2 MW gas engine based on Series 4000 Diesel and Gas. It will be explained why this product is a promising concept for marine applications in particular. Design details like gas supply and injection System will be presented. Safety issues will be discussed and how these are designed on the engine. Results from the test bench will demonstrate the diesel-like performance while lowering the emissions. Finally there are a lot of challanges beside the engine which are ship design and gas fuelling. Having solved this, gas engines will have a great future in the market.
