How can we increase the power of an engine? To generate more power we require more Fuel and Air. Conventionally this was achieved by increasing length of piston stroke or the number of cylinders. But what if there’s a way to achieve all without making any change in the engine. Yes! Using Turbocharger we can […]

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 ignition timing early or late for affecting engine performance. We all know early ignition can

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 something about them even more for few; you already be used to reassembling them in

The hot topic among marine engineering students and seafarer preparing for the exam has been of Tappet Clearance. The clearance in between the valve stem and rocker arm is termed as tappet clearance. They facilitate the operation of rocker arm in a four-stroke engine; by providing sufficient space for thermal expansion. Tappet clearance is taken

Exhaust valves are subjected to high temperature and shoot. This can sometimes lead to valve seizure, heavy shoot deposits, and local Overheating. A Rotocap is used to protect the exhaust valve from above concerns extending its overall life. It is fitted on the exhaust valves of auxiliary or medium-speed engines. Main engines have rotating vanes

Centrifugal pumps are one of the most commonly used pumps on the earth with ever growing applications. They are simple and reliable machine of any machinery space. On ship they are the simplest of machinery installed in the engine room. They are unique for its high flow rate at variable dynamic head with less repairs.
