How Does A Marine Engine Work?

A marine engine is fundamentally a diesel engine which is used in most large sized cruisers, yachts, and other types of commercial vehicles such as trawlers and work boats.

In a diesel engine, only air is inserted into the cylinder head. This air is then compressed to around six hundred pounds per square inch. This high degree of compression causes the air to get heated to a temperature of around a thousand degrees Fahrenheit. At this precise time period, fuel is injected straight into the compressed air. This results in the fuel getting ignited due to extreme heat, in turn resulting in a high speed expansion of gases which push the piston downwards, and provide power to the crankshaft.

There are many advantages to a diesel engine, for example it uses less fuel as compared to a gasoline engine while performing the same amount of work.
