Ic Engine Advantages And Disadvantages

CHAPTER 1
INTRODUTION
The increasing trends and demands in the automotive world, there is always tug and tie between the designer and customer. To cope with existing competition in the modern times there is always need for great improvement in compatibility of the engine models. In this chapter the brief introduction about internal combustion engine (IC engine) is presented. The various components, type and recent advancements in IC engine are also presented in this chapter.
As the name implies, the internal combustion engines briefly written as (I.C engines) are those engines in which the combustion of fuel takes place inside the engine cylinder. The I.C. Engines uses either petrol or diesel as their fuel. In petrol engines air and fuel

The distinctive feature of IC engine is that combustion and conversion of heat energy into mechanical work occur inside the cylinder. These engines are noted for their efficiency and low operating cost. Such is the versatility of the IC engines that is development has a wide spread effect on the life of every nation. Petrol, gas and diesel engines, wankle engines, and open cycle gas turbines are examples of internal combustion engines. The advantages of internal combustion engines are greater mechanical simplicity, lower weight due to absence of auxiliary equipment like boiler and condenser and thus lower price, higher overall potency, and lesser demand of water for dissipation of energy through cooling system. IC engines square measure in the main used for transport vehicles, locomotives, agricultural pumping sets and aircrafts etc.,
1.3 COMPONENTS OF IC ENGINE

As a matter of fact, an IC engine consists of hundreds of different parts, which are important for its proper working. The main components, which are important, are described below.

1.3.1

A piston is in cylindrical form that climbs and down inside the cylinder. Cylinder rings give a sliding seal between the external edge of the cylinder and the inward edge of the cylinder. The rings fill two needs:
.
They keep the fuel/air mixture and fumes in the combustion chamber from spilling into the sump duaring pressure and burning. They keep oil in the sump from spilling into the combustion range, where it would be blazed and lost.
The blazing of the fuel-air mixture inside the cylinder applies a weight on the piston, in this manner pushing it downwards. They transmit the power of combustion to the crankshaft through the interfacing road. The activity of the joining rod and crankshaft changes over this descending movement to a turning movement. piston goes about as an aide for the upper end of the joining rod and serves as a transporter for the piston rings used to seal the pressure in the
