Mitsubishi Marine Diesel Engine: workshop manuals PDF

Marine diesel engines occupy a solid niche in the market of power plants; they are used in most modern ships and vessels as the main and / or auxiliary element of the power system. Its task is to ensure the progress of the vessel, the operation of pumps, electric generators and other units. A diesel internal combustion engine is more economical in comparison with gas turbine and steam plants, easier to maintain and operate. We offer you modern, highly reliable marine engines, which you can buy from an authorized dealer of Mitsubishi, a recognized world leader in the production of diesel engines for various fields of activity.

Marine diesel engines are two- or four-stroke internal combustion engines in which the thermal energy of the fuel burned in the cylinders is converted into the mechanical energy of the movement of the piston and the speed of the crankshaft. The four-stroke duty cycle is carried out in 4 piston strokes or two crankshaft revolutions, in a 2-stroke cycle - in two piston strokes and a crankshaft revolution.

Classification

• Rotation frequency. They are divided into low-speed - from 100 to 350 rpm, medium-speed - from 350 to 750 rpm and high-speed - from 750 to 1500 rpm.
• Diesel power. They are divided into low power motors — up to 73.5 kW, medium - from 73.5 to 735 kW, and high-power motors with a capacity of more than 735 kW.
• According to their purpose, they are divided into main (ensuring the progress of the vessel) and auxiliary (ensuring the operation of fans, electric generators, pumps, etc.).
• The shaft rotation method is reversible and non-reversible. The latter can provide the possibility of reverse through the use of additional equipment - a special reverse gear.

The main requirements are:

• Great resource of work.
• Automation control with the possibility of monitoring from the cabin, long work without manual adjustment of the mode.
• Ability to work on heavy grades of diesel fuel.
• Resistance to high ambient temperatures.
• Compact size.
• Simplified access to the main nodes, low labor-intensive maintenance.

All of the above requirements are fully consistent with Mitsubishi marine engines. High quality solutions provide the authority of a leading global manufacturer, the use of innovative developments, strict adherence to international quality requirements and environmental safety.

Mitsubishi diesel engines are widely used in many classes of ships - from pilot boats to tankers and cruise liners. One of their main advantages is high reliability in operation, which guarantees high financial return on invested funds. High-quality materials and components, innovative technical solutions (in particular in lubrication and cooling systems) ensure long-term and successful operation of the equipment.

I would also like to note a modern, compact design that provides ease of installation and maintenance of a diesel engine. Thanks to the separation of the heads, separate maintenance of each cylinder can be carried out. A modern fuel supply system, high-pressure fuel pump and a turbocharger contribute to maximum combustion, high efficiency, from 95.5 percent or more.
