Difference Between Medium And High Speed Marine Engines
Aug 24, 2018



The difference between high and medium speed marine engines is as follows:


1. The general marine engine belongs to the category of low-speed engine, the engine speed is generally below 800rpm (except for special speedboats), because the marine engine needs to be matched with the propeller, the propeller speed is about 600-800rpm. Considering the efficiency of the matching, too high engine speed is not helpful; other large cargo ships or cruise ships use engines that burn heavy oil (the worst kind of oil), which is usually a two-stroke low-speed engine, but also a high-power four-stroke medium-speed engine, which is usually used as an auxiliary engine on board ships. Electricity and so on.


2. the automobile engine is more general. General commercial vehicles (heavy trucks) and construction machinery are mainly used by diesel engines, six cylinders and four strokes compression ignition type is the majority. For passenger cars (cars, etc.) are generally gasoline engines (except for special off-road vehicles), need to be ignited by spark plugs, the engine structure varies with different displacement.
