Piston Skirt, Piston Rod and Trunk Piston
Piston is an important part of the combustion chamber of a marine engine which converts the gas force into mechanical power by reciprocating motion. Piston skirt, piston rod and trunk piston…
An Overview of Common Rail System of Marine Engines
The common rail system, as the name suggest, is a system which is common for every cylinder or unit of the marine engine. Marine engines of the early times had…
Factors Affecting Lift
WHAT FACTORS AFFECT LIFT? The size and shape of the wing, the angle at which it meets the oncoming air, the speed at which it moves through the air, even…
Intelligent Engines – The New Generation Machines
Today the world needs engines that can cope up with the stringent emission norms and higher demands for robust, reliable and smart engines with low operational cost. To achieve the…
Subsonic Wings
WHAT MAKES A WING WORK? Let's use a wing to help get a better understanding of lift at subsonic speeds. With a typical subsonic wing, the upper surface is more…
Air in Motion
FLIGHT BEGINS WITH AIR IN MOTION As an airplane moves through the air, its wings cause changes in the speed and pressure of the air moving past them. These changes…
Aerodynamics of automobiles
Automobiles started using aerodynamic body shapes in the early part of their history. As engines became more powerful and cars became faster, automobile engineers realized that wind resistance significantly hindered…
What Is Aerodynamics?
Aerodynamics is the study of how gases interact with moving bodies. Because the gas that we encounter most is air, aerodynamics is primarily concerned with the forces of drag and…
Introduction to Aerodynamics
Flying... still kind of magic every time. The math describing Fluid Dynamics was extensively studied and eventually written down in a complete set of Partial Differential Equations known as the Navier-Stokes. Those equations…
How to Measure Cylinder Liner Bore Wear?
Cylinder liner ovality has to be gauged at regular intervals as specified in the maintenance manual. The records of gauging are kept for each cylinder and wear rate is calculated.…
