17 Automobile Engineering Questions and Answers:

1 :: WHY BIG TYRE USED IN REAR OF VEH?

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.

4 :: Explain different between two stroke engine four stroke engine?

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.
