We might have heard these words SI and CI engines when buying a brand new vehicle. But do you know what these words mean and what is the significance of them? SI engine or Spark Ignition engine and CI or Compression Ignition engine are the two most common classifications of an internal combustion engine. But…
The basic definition of an internal combustion engine states that it is a component that converts chemical or fuel energy into mechanical energy. This is governed by the law of conservation of energy. This definition is well established to all kind of components which converts chemical energy to mechanical energy, from huge marine engines to…
Construction:- The sketch shows a typical turbocharger fitted in large slow speed engines. The main parts are the turbine rotor with blades and the impeller mounted on a common shafted enclosed in a volute casing. The exhaust gas enters the water-cooled turbine casing through a grid, which prevents any broken pieces of piston ring from…
Hello Everyone! We all know, vultures are called scavengers, because they eat up the left-over of animals helping in keeping the environment clean. Scavenging in engines is something similar, done with the intention of cleaning. So, what are we waiting for! Let me take you on a ride where you will learn about the concept…
As soon as we see warships, anywhere around the sea, or in an image, we immediately know that they are made to be stealthy. But we never ask what exactly makes the ship stealthy, and from what object does the ship hide itself to become stealthy. We will start from right from the basics, and…
What are Tie Rods and its Function?For better understanding the use of tie rods and tie bolts let us first understand what is happening inside the cylinder of an IC Engine. The processes that take place inside an IC engine are Suction, Compression, Expansion, Exhaust. Do refer to this article for further information if needed….
Oily Water Separator (OWS) is of utmost importance on board ship. They are used to separate oil from oily wastewater I.e., bilge water before discharging this wastewater into the environment. These waste discharge water must comply with the requirements laid out in Marpol 73/78. The International Maritime Organization (IMO) has published regulations through the Marine…
First of all, we should know about Cylinder cover which is also known as Cylinder head is tightened down against the top of the cylinder liner by means of nuts and studs. The nuts are tightened by means of hydraulic jacks. It seals the top end of the cylinder space. Sealing between the cylinder cover…
Fresh water is required for domestic purpose, cooling intricate spaces. Although costly, freshwater cooling doesn’t lead to corrosion. The generation of fresh water onboard uses two things which are available in abundance onboard- Heat and Seawater. The generation of fresh water onboard takes place in two ways:- Distillation Osmotic de-salinators Freshwater generator (also called evaporator…
The following processes take place during one cycle of an Internal Combustion Engine. Suction Compression Expansion Exhaust Suction:- The charge which is usually a mixture of air and fuel is drawn into the engine during suction. Due to the downward movement of the piston, the charge is taken inside the engine because the pressure inside…
