Diesel engineswork by compressing only the air. This increases the air temperature inside the cylinder to such ahigh degree that atomized diesel fuel that is injected into the combustion chamber ignitesspontaneously. This contrasts with Spark-ignition engines such as a petrol engine (gasolineengine) or gas engine (using a gaseous fuel as opposed to petrol), which use a spark plug toignite an air-fuel mixture. In diesel engines, glow plugs (combustion chamber pre-warmers) maybe used to aid starting in cold weather, or when the engine uses a lower compression-ratio, orboth. The original diesel engine operates on the "constant pressure" cycle of gradual combustionand produces no audible knock.Inn additional, Diesel engines may be designed as either two-stroke or four-stroke cycles.They were originally used as a more efficient replacement for stationary steam engines. Since the1910s they have been used in submarines and ships and also use in locomotives, trucks, heavyequipment and electricity generation plants followed later.Diesel engine use for large ships have engines of all types, from 2- or 4- stroke dieselengines to turbines similar to those on airplanes or even just several diesel generators that powerthrusters or pods. It all depends on what the ship is designed to do and how it will be operated.The majority of large commercial ships, from freighters to oil tankers, use 2-stroke, slow speeddiesel engines connected to their propeller. Compared to other fuels, this is very cheap but alsoknown for lots of heavy air pollutants including sulfur oxides and nitrogen oxides.
DIESEL ENGINE IN CARGO SHIP Most of the diesel engines are utilized by the entire ship and have different powergenerators. Diesel engines are also used in cargo ships and various types of ships. Typical shipssuch as bots also use diesel engines. All diesel engines (including marine diesel engines) are veryreliable and extremely durable machines. Diesel engines are also fairly economical.
