The marine diesel engine or ship’s main engine is the heart of the ship; and it needs maintenance too for smooth operation. With all major loading and discharge schedules made in advance; any critical damage leads to a huge loss…
What is the starting air distributor? It is the part of the starting air system responsible for providing pilot air to starting an air valve as per the correct starting order. For an idle six-cylinder engine; the injection timing of…
You must have noticed the heat coming from an engine if you ride a motorcycle or monitored heavy / large diesel engine. Where does this heat come from? Heat is produced in cylinders during the power stroke of an engine.…
Understanding scavenging requires us to understand why we need scavenging in the first place. We knew that an adequate amount of oxygen is required to start and sustain any combustion. Now since air contains 21% of oxygen; something engine needs…
Fuel pump and injector directly affects the performance of a marine diesel engine. The quality of combustion in an engine depends on the working of a fuel injector; which leading to proper automation and optimum injection timing. Atomization is the…
Proper ignition and combustion of fuel is the key to efficient marine engine. With use of residual fuel for ignition other less important factors become critical; such as the delay period between the fuel injection and ignition. With most of…
Have you wondered, whats is the use for variable injection timing or “VIT” if we always learn and told to avoid early and late ignition ! Why am i asking this question? Variable injection timing is a process to alter…
A Marine diesel engine consists of many working parts. Even different components make few modification in its design but their function remains the same. Each component has a definite function and location in its working. Chances are, you already know…
You have heard the term “Air starting system”; but don’t know what it is? 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…
