compression ratio r it is the ratio of the total cylinder volume when the piston is at the bottom dead centre vt to the clearance volume vcr
clearance volume vc the nominal volume of the combustion chamber above the piston when it is at the top dead centre is the clearance volume it is
displacement or swept volume vs the nominal volume swept by the working piston when travelling from one dead centre to the other is called the
dead centre the position of the working piston and the moving parts which are mechanically connected to it at the moment when the direction of the
stroke the nominal distance through which a working piston moves between two successive reversals of its direction of motion is called the stroke and
piston area the area of a circle of diameter equal to the cylinder bore is called the piston area and is designated by the letter a and is usually
cylinder bore the nominal inner diameter of the working cylinder is called the cylinder bore and is designated by the letter d and is usually
cam this is an integral part of camshaft a cam is designed in such a way as to open or close the valves at the correct timing and keep them open for
camshaft the camshaft controls the opening and closing of the two valves the associated parts are push rods rocker arms and valve springs the

inlet and exhaust valves valves are commonly mushroom shaped poppet type they are provided on the cylinder for regulation of the charge coming into
exhaust manifold the pipe which connects the exhaust system to the exhaust valve of the engine through which the products of combustion escape into
inlet manifold the pipe which connects the intake system to the inlet valve of the engine through which air or air-fuel mixture is drawn into the
functions of the piston ring to form a seal for high pressure gases from the combustion chamber against leak into the crankcase to provide
desirable characteristics of the piston silent in operation seizure between piston surface and inside of cylinder should not occur sufficiently
functions of the piston to transmit force of explosion to the crankshaft to form a seal so that high pressure gases from the combustion chamber do
combustion chamber or clearance volume combustion chamber is a space between the cylinder head and the piston top when the piston is at top dead

a cantilever has two couples 1stclockwise 15knm placed at 13l from support and 2nd anti-clockwise 10knm at 23l from the support what should be the
working of a four-stroke engine to understand the working of a four-stroke motorcycle engine the whole operation can be divided into four parts known
two wheeler engines engine is a unit of motorcycle that runs the motorcycle by converting fuel energy to mechanical power this power comes from the
basic concept like any fine machine a motorcycle can be split into various systems like lubrication system transmission system electrical system
objectives after studying this unit you should be able to describe how a motorcycle works identify the transmission system and its various part
