Internal combustion engine theory :

Note : Following subjects are expected to cover in this site and now we are in progress

Design theories that embody IC engine concepts

In order to investigate in to chemistry of combustion, Kinematics of internal combustion engine, the gaseous cycles, thermodynamics and heat transfer to the major components, we should have an idea of the basic functioning and component interaction in a modern internal combustion engine, specifically; two and four-stroke cycles as they relate to reciprocating and rotary engine designs.

The function and operation of all major components and systems within a modern internal combustion engine and general thermodynamic concepts governing the operation of an internal combustion engine and its various cycles to compare the principle operational differences of the various fuels used in internal combustion engines, their availability, and understand the applicability of each we shoul be able to identify the operational principles of oscillating engine behind the timing and working relationships among all internal components.
We have now recognized the limitations of the modern internal combustion engine and current designs; implementations of the Enginewos depend not only the on the perform but a basic assessment and evaluation of new, cutting-edge designs and new powertrain initiatives as they apply to the mobility industry.

Subjects covered on this site are :

Fundamental Operating Procedures
Engine Technology Development
Internal combustion process
External combustion process
Spark ignition system
Compression ignition system
Engine Technology and future trends
2-stroke combustion cycle
4-stroke combustion cycle
Crank mechanism, including Pistons, connecting rods and crankshaft

Valve train design and timing gear designs involove deep understanding of the combustion process. Vast research and development activities involve design of valve train camshaft and timing gear. While Valvetrain, Engine block, cylinder and head geometry involve considation of practical aspects on Manifold, surface finish, track length, Fuel systems, carburetors, fuel injection. Introducing Turbo- and super-charger will improve efficiency of the engine. Then also has to taken into consideration of Ignition, timing and spark advance as well as Perfecting Fuel Delivery Systems Air intake systems such as the problem of part throttle operation and Intake manifold design and tuning effecting the emmision.
