what does horse power, RPM and CC specify in car?

Question

is it like more horse power means more speed? and if yes then what does RPM and CC specify? whats the relation between these three?

Answer 1

Horse power specifies the useable power devoloped in the engine. Speed is directly propotional to horse power. The greater the horse power you have, the faster you can go.

RPM stands for Revolutions Per Minute.It indicates the speed at which the engine is running.

CC stands for Cubic Centimeters.It specifies the displacement of the engine,the amount of air fuel mixture required for one cycle of operation.

There exists a direct relation between the three.

To increase the Horse Power of an Engine we have to increase the amount of air fuel mixture fed to the engine.This can be done in the following ways
1) Increase the CC.
Increasing the CC of the engine increases the amount of air fuel mixture consumed by the engine(thus increasing power)
2) Increasing the RPM
Increasing the RPM increases the amount of air fuel mixture consumed by the engine within a given interval of time(thus increasing power) although the physical size of the engine remains the same


So the Horsepower is dependent on both the RPM and CC

Answer 2

These are three different specifications of a car. The horse power gives the power of the engine which in turn depends on CC, i.e the cubic capacity. The cubic capacity is the total swept volume of the engine. For example if an engine has four cylinders the cc or cubic capacity of the engine is 4 x swept volume of each cylinder. Swept volume is calculated by multiplying stroke length of piston by area of each cylinder section. The RPM of an engine varies with acceleration and gear selection. However the maximum torque developed by an engine is specified at a particular RPM, i.e revolution per minute.

Answer 3

Horse power refers to the Power of the engine. One HP equals 746 Watts.
RPM refers to the revolutions per minute ie the speed of the piston moving in the engine.
CC refers to the cubic capacity ie. the volume displaced by the piston in the engine.

yes. more horse power means more speed. the horse power of the engine is an indication of the engine's power, while the rpm is a component in calculating the power. so more the rpm more is the horse power. CC indicates the consumption of the air-fuel mixture and so more the CC more is the acceleration and so more is the fuel consumption.

Answer 4

Horse power tells you the power of your car.

CC - cubic centimeter is the piston compressionin one cycle of the car. That is the volume of the cylinder in which the piston moves.

RPM - rotations / revolutions per minute is the speed at which your engine roatates. The higher the speed the higher the rotation. Also rotation will be higher if the gear is lower.

Answer 5

cubic centimeters refers to how much air/fuel mixture passes through the engine (on the intake stroke) in one revolution. = cc
-- a larger cc number means a bigger engine.
--rpm = rotation per minute of the crankshaft
--horse power = the more air/ fuel mixture the engine can burn- that is take in, burn ,and pump out the tailpipe- the higher the horse power. an engine is just a pump really- the bigger the pump - the more horsepower could be produced.

Answer 6

rpm= revolutions per minute, its how fast the engine is turning at the crank shaft.

CC is cubic centimeters, its a measure for the combustion chamber of the engine, also called displacement.

Horsepower is the measure of power the engine puts out. And horsepower is torque(the ability in power to start moving the car) over a distance.

Answer 7

cc=cubic centimeter..is the volume swept by the piston in the cylinder...bigger cylinder used for producing more power...hp=horse power , it is the power produced but this power is not completely used as there are significant friction losses in the engine thus reducing it considerably and brake horse power is the actual useful power available...rpm=revolutions per minutes represents the rotational speed of crankshaft...greater the speed less torque and less power..

Answer 8

horsepower and CC are measurements of size in an internal combustion engine. The larger the number, the greater the power. RPM is revolutions per minute and counts how many times the crankshaft turns in one minute. Of course, the greater the power, the faster potential rpm you have, ergo, speed.

Answer 9

RPM = Revolutions Per Minute
CC= Cubic Centimeters

The more revolutions per minute the engine is doing the fast the car is goiong.

Cubic centimeters refers to how much the engine weighs.

Horse power is a way of measuring how fast the engine is capable of going at it's top speed.

Answer 10

not enough information to make any judgment. All else being equally (quality of manufacture, quality of design, mass of vehicle, etc) the slower revving one will last longer, and will accelerate faster. The top speed will be the same if the gearing is appropriate for each so that the peak power will occur just below the top speed. Define "better" Note torque is directly related to horsepower and rpm.
