Automobile Engineering

In a two stroke engine, for every two rotations of the crank

shaft there will be one power stroke.Hence during

compression stroke, fuel will be drawn in to the crank case

(suction) and during power stroke, burnt fuel will be thrown

out through transfer ports (exaust).

In a four stroke engine, for every four rotations of the

crank shaft there will be one power stroke.

Here, suction, compression,power & exaust strokes are seperate

as there will be inlet and exaust valves.

spray painting it is generally used for painting in a very

smaller areas of any part and where it is very hard to paint

in a brush .... And to improve faster rate of painting,,

spray painting r used........usually reciprocating

compressor r used but size depends upon requirement...........

Tuning: The adjutment of a system or circuit to bring the optimum correctness

Mapping: Making or design of maps

Boiler horse power (BHP) is a power unit used for measuring the power output of boilers, widely used in the past, but now confined to North America. The boiler horsepower conversion formula is as follows.

1 Boiler Horsepower = 9,809.5 Watts

A geometric parameter which is positive if the kingpin axis

intersects the wheel plane at or below ground level, or is

negative if the point of intersection is above ground level.

Also called scrub radius

Tractors have big rear tires because ,the larger the surface

area of the tractor's wheels touching the ground, the more

pulling power you have. Like how tractor pullers have large

tires.

Another reason is that the tractor doesn't have to operate

at a higher speed to get the same ground speed with larger

tires. Gear ratios don't have to be as high b/c of the

larger tires.

When we accelerate our vehicle, it provide more fuel into the cylinder from fuel injector. Yes you are right valve operating time is fixed bt in this short period of opening we provide more quantity of air-fuel mixture.

it depends on pascal law. As the pressure in the system is the same, the force that the fluid gives to the surroundings is therefore equal to pressure x area. In such a way, a small piston feels a small force and a large piston feels a large force

the range of two sroke engine is too high compare to the

four stroke engine be cause of each revalution one power in

two sroke engine . i canot see the 2 sroke engine in

car.power loss is more.

During the process of vulcanisation of rubber to make it

sheer resistant to make tyres out of it, a certain

proportion of carbon is mixed into it. Without this

procedure the tyres will not be able to withstand the

friction n stress of the road. This carbon is responsible

for giving tyres the characteristic black colour.. When

ozone combines with ultraviolet light from the sun, it

attacks the tire polymer. To prevent tires from rapidly

deteriorating, a sacrificial absorber is used, "carbon

black" - which, fittingly, makes tires black

"SAE" STAND "SOCIETY OF AUTOMOTIVE ENGINEERS" (USA).

SAE20W40 :4WHEELER ENGINE,2 WHEELER ENGINE, GEAR BOX &CLUTCH.

for maximum torque provied

CC stands for Cubic centimeter. CC represents the total

volume of an engine cylinder. The engine which has more

CC , can produce more power than others.

BHP stands for Brake horse power

As the name implies it is the braking power required to

stall a engine Means horse power required to stop engine

rotation

yes, absolutely .. It leads to higher wear and tear in

cyclinder liners,piston and damage of the piston .. It even

leads to knocking and detonation where abnormal combustion

appears and dark smoke and harsh sound will be produced by

the engine.

No, the type of fitting & design does not vary for automotive

segment. Its the same. However, its different in case of

aerospace & other sector.

In the fittings, usually of hole/shaft one of those is made at

the basic size so that it can accommodate the other one.

IN BS2 there is No catalytic converter to reduce formation

of co and HC whereas in BS3 catalytic converter is

available to reduce the formation of HC and CO. So less

emission of HC and co will take place in BS3

injecter pressure is 220 kg/cm square

it is weight of drive torque which is bolted to chassis of the car.
