Starting Systems In Marine Diesel Engines

starting systems in marine diesel engines

Well, the Starting air system uses compressed air to start the main engine. Compressed air is inserted into various cylinders in a proper sequence to provide the initial torque; required to overcome the inertia of reciprocating parts. Normally, compressed air at 20 to 30 bar pressure is required to start an engine in a certain direction.

Independently driven pumps were provided to prime the system for starting. Later systems used hydraulically operated injectors, the delivery of fuel being controlled by a cam operated valve. Fuel quantity was controlled by an eccentric on the cam follower.

Diagnose and fix marine diesel engine problems

The auxiliary diesel engine is mostly started with the help of compressed air,depending upon the size of the engine. Other means of starting includes Electric start (battery) and air motor (engaged in the flywheel). The most common method is the use of compressed air. The lay out for starting the auxiliary engine is given below.

Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the ...

For model-specific Troubleshooting, refer to SUBJECT, DIAGNOSTIC, or TESTING articles available in the section(s) you are accessing. NOTE: Diesel engines mechanical diagnosis is the same as gasoline engines for items such as noisy valves, bearings, pistons, etc.

Types And Working Of Starting System Diesel Engines

In diesel engines, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons, transforming chemical energy into mechanical energy. In 1919, Clessie Lyle Cummins founded Cummins Engine Company to improve diesel technology and produce the world’s finest engines.
