2.7 Fuel Supply System
In petrol engine a device called "carburetor" is used to send the correct proportion of air-petrol mixture in to the cylinder in a petrol engine (spark ignition engine) and diesel engine (compression ignition engine) are different.
In petrol ...

2.6 The Diesel Cycle
In actual spark-ignition engines, the upper limit of compression ratio is limited by the self ignition temperature of the fuel. This limitation on the compression ratio can be circumvented if air and fuel are compressed separately and ...

2.5 The Otto Cycle
Nicolaus Otto (1876), proposed a constant-volume heat addition cycle which forms the basis for the working of todays's spark-ignition engines. The cycle is shown on p-V and T-s diagram in fig (a) and (b) respectively.
When the engine ...

2.4 Working of IC Engines
The four-stroke-cycle principle can be described as follows:
During the intake stroke, the piston travels downward in the cylinder from TDC to BDC, the volume of the cylinder chamber is enlarged. This enlargement of the cylinder chamber ...

Introduction to Internal Combustion (IC) Engines
Posted by Vishnu on April 12th, 2010 12:12 AM | No Comment
2.1 Introduction
The purpose of internal combustion (IC) engines is the conversion of mechanical energy from chemical energy contained in the fuel. This energy is released by burning or oxidized the fuel inside the engine.
JJE Lenoir (1822-1900) developed the first marketable ...
