What is BHP? How can you measure BHP?
BHP is ‘Brake Horsepower’. It reflects the powerfulness of the brakes of the
vehicles. BHP stands for how much power will be required to make the engine
stop working i.e. to stop the rotation of the engine.
BHP = 2 times pi times torque times revolutions; all this divided by 550.
Pi is 3.1416 and torque is in pounds-feet, and revolutions are revs per second
What will happen if someone adds oil to the fuel of four stroke bike engine?
This will result in damaging of the engine faster. Adding oil will lead to the
higher wear and tear of the cylinder liner, piston and damage to the piston. It
will lead to abnormal combustion and knocking and detonation. Dark smoke and
abnormal sounds will be generated by the engine. One should not mix oil with
the fuel of four stroke engine.
How will you differentiate between two stroke engine and four stroke engine?
In case of two stroke engine, rotation of crank shaft will be power stroke for
every two rotations. During compression stroke, fuel will flow towards the
crank case(suction) and during power stroke, exhaust will emit the burnt fuel
through the transfer ports.
While in case of four stroke engine, rotation of crank shaft will be power
stroke for every four rotation. Moreover, suction compression power and exhaust
strokes are separate as there will be inlet and exhaust valves.
What is the size of the recommended compressor CFM? Where it can be used?
It is generally used in spray painting of very small areas. It can be used where
painting with brush is very difficult. thus to improve the rate of painting the
spray painting is used as this method is very fast and efficient. Usually
reciprocating compressors are used but size depends on requirements.
What is the range of engine efficiency in case of two stroke engine?
The two stroke engines have very high range to be compared to the four stroke
engines. Because power stroke is generated every two revolution while in four
stroke, power stroke is generated every four revolutions.
What do you understand by CC of engine?
The meaning of CC is cubic centimeters. It represents the total volume of the
engine cylinder. This reflects that the engines with more CC can generate more
powers than the other engines. CC can also be related as inversely proportional
to the fuel consumption.
What is back compressor in engines?
Back compression means the compression capability of the engine. An diesel
engine can compress at the ratio of 14:1 to as high as 25:1. Thus the higher
compression leads to better efficiency of the engine. Thick black smoke is
emitted when the engine’s compression is reduced which leads to the deformed
ead-gasket lead into crankcase.
How air conditioners work in cars?
Air conditioners are based on the principles of evaporation and condensation and
then compression and expansion. The hot air of the car is removed by the
process of evaporation and then the condensation of the evaporated air takes
places which is then further compressed by the compressor and then finally
expanded to us in the form of cold breeze. Somehow, Air conditioning reduces
the average of the car, as the energy is required to remove the hot air and
then compression and expansion.
