Low speed engines for ships

How to choose this product

A low-speed ships engine is a diesel engine which operates at less than 350 revolutions per minute (rpm). Normally, it is a two-stroke engine burning low-grade fuel.

Applications

These engines are commonly used to power ships, since they generate great power.

Technologies

Such engines are very large, with cylinder bores between 700 and 1060 millimeters. Each cylinder can generate up to 4500 hp. Diesel engine fuel is ignited by pressure. Since diesel fuel contains high levels of acid-forming sulfur, each cylinder is individually lubricated with high-alkaline oil to prevent corrosion of piston rings and cylinders.

How to choose

Choice will depend on available engine room space, ship power requirements, operating rpm, type of fuel and similar factors.

Advantages

- Powerful
- Economical

Disadvantages

- Bulky
- Fuel requires pre-treatment
