HEAT ENGINES

Any type of engine or machine which derives heat energy from the combustion of fuel or any other source and converts this energy into mechanical work is termed as a “heat engine”.

Fuel Heat Engines Mechanical Works

ENGINE PARTS

Cylinder Head. In an IC engine, the cylinder head sits atop the

cylinders and consists of a platform containing part of the combustion chamber and the location of the valves and spark plugs.

SPARK PLUG

The spark plug ignites the air/fuel mixture inside the cylinder.

This occurs when high voltage, triggered at precisely the right instant, bridges the gap between the center and the ground electrodes. The end result is an even burning of the air/fuel mixture inside the cylinder..

ROCKER ARM

The rocker arm is a reciprocating lever that conveys radialinformation from the cam lobe into linear information at the poppet valve to open it. One end is raised and lowered by the rotating lobes of the camshaft (either directly or via a lifter (tappet) and pushrod) while the other end acts on the valve stem.

CYLINDER LINER

The circular housing that the piston moves in when the Cylinder is not an integral part of the block. Also known as a "Sleeve”.

CYLINDER BLOCK

The cylinder block or engine block is a machined casting (or sometimes an assembly of modules) containing cylindrically bored holes for the pistons of a multi-cylinder reciprocating internal combustion engine.

PISTON

A piston is a component of reciprocating engines, pumps andgas compressors. It is located in a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transferforce from expanding gas in the cylinder to the crankshaft via apiston rod and/or connecting rod.

CONNECTING ROD

In a reciprocating piston engine, the connecting rod or conrod connects the piston to the crank or crankshaft.The small end attaches to the piston pin.The big end connects to the bearing journal on the crank throw, running on replaceable bearing shells.

CRANKSHAFT

Sometimes casually abbreviated to crank, is the part of an engine which translates reciprocating linear piston motion into rotation. To convert the reciprocating motion into rotation, the crankshaft has "crank throws" or "crankpins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach.

FLYWHEEL

A flywheel is a rotating disc used as a storage device for kinetic energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based (reciprocating) engine

SUMP TANK

The sump surrounds the crankshaft. It contains some amount of oil, which collecting the bottom of the sump (the oil pan).
