INTERNAL COMBUSTION ENGINE & GAS TURBINES Module - I INTRODUCTION Heat engine: A heat engine is a device which transforms the chemical energy of a fuel into thermal energy and uses this energy to produce mechanical work. Air enters the engine through the intake that leads to the combustion chambers (cylinders). Detection of fault is also difficult for maintenance technicians due to broad range of faults and combination of the faults. After combustion of fuel, much heat energy is generated, this is converted into mechanical energy.There are two types of IC engines: rotary and reciprocating engines. Classification of Internal Combustion Engines - View presentation slides online. Passages for the cooling water are cast into the block. They all operate on the internal combustion principle, and the application of basic principles of construction to particular needs or systems of manufacture has caused certain designs to be recognized as conventional. The expanding gases are used to directly move a piston, turbine blades, rotor(s), or the engine itself thus doing useful work. Internal combustion engines - If the combustion fuel takes place inside the engine cylinder, it is an internal combustion engine. Signals containing a large number of engine cycles are used to obtain a number of observations of each feature. A naturally aspirated engine is an internal combustion engine in which oxygen intake depends solely on atmospheric pressure and does not rely on forced induction through a turbocharger or a supercharger.
