Methanol Fueled Marine Diesel Engine

Now a day’s concerns about methanol have increased from the viewpoints of environmental protection and versatility of fuels at a global scale. Energetic research on methanol-fueled automobile engines has been forwarded from the viewpoints of low environmental pollution and the use of alternate fuel since the oil crisis, and they are now being tested on vehicles in various countries in the world. Desire for saving of maintenance cost and labour prevails as well as the environmental problems in the field of marine engines. From these motives scientists have carried out research and development of a methanol fueled marine diesel engine which is quite different from automobile engines in the size, main particulars, working condition and durability. Although scientists have made a great use of invaluable knowledge from automotive technology, some special studies were necessary due to these differences. Ignition method is a typical one. Dual fuel injection system was tried for trouble-free ignition of methanol fuel. This system is thought to be the most favorable ignition method for marine diesel engines which have to withstand quick load change and accept no misfiring.
