A little more indepth about car functions?

Hello, I just turned 16 and I am really getting into cars the more I am around them, but there are a few things i do not know what they mean. Could you give me a brief description of what the following do or what purpose they are for.


BHP?


Horsepower?


Torque?


RPM?


Liters?





That is all for now, thank you.
A little more indepth about car functions?
BHP stands for Brake Horse Power. the British use it. its a way of measuring HP with a Braking device. We just say "horsepower"

Horsepower and Torque are kinda related. Horsepower is calculated with Torque and speed in a math equation.


this is a GOOD page on both.

RPM is "Rotation Per Minute"





and Liters are like Gallons or Cubic Inches (either is a form of Volume)except they are about the size of a Quart of oil. 3.785 liters make a gallon.


16.5 Cubic centimeters make a Cubic inch


1000 cubic centimeters make a Liter

Bulk Horse Power - horsepower that the engine produces as a certain rpm.


Horsepower - the amount of power an engine produces.


Torque - the 'turning' power produced by an engine.


RPM - Rotations Per Minute.


Liters - European measurement for an engine versus Cubic Inches.





There are different ways to say the above, but you get the point. See link below for lots more info.


Good question.
Reply:BHP Brake Horsepower - measured at the crankshaft


Horsepower - measured at the tire


Torque is the force of twisting, likely expressed in foot pounds


RPM is Revolutions per minute


Liters is the displacement of the cylinders.
Reply:BHP Brake HP. To the Flywheel(Engione only baiscly)


Horsepower the more the better.


Torque its what pushes you to the seat when u acc.


RPM revloutions per minute. How fast the engine is turns.


Liters The displacment ofr the engine.More the better
Reply:BHP = flywheel horsepower (the B stands for break as I recall)


horsepower = power, compared to a horse.


torque = how willing the engine is to move the wheels under load (why cars can spin tires or smack you back into your seat)


rpm = how fast the engine is turning


liters = engine displacement is measured with these, if an engine has 3 liters it means you could theoretically fill the engine with 3 liters of air and gas in 1 rotation.
Reply:BHP is brake horsepower, a measure of the vehicle's ability to do work. It is different from horsepower in the BHP generally refers to the engines "net" ability to produce power, often horsepower is a measure of the engine's ability without the inclusion of things like an alternator or water pump.





http://en.wikipedia.org/wiki/Horsepower





Torque is the ability of the engine to generate a torsional moment, that is turning force. It is measure in ft-lbf, that is so many pounds of force at a 1 ft radius. Torque is important as it is what gets you moving. Diesel engines produce huge amounts of torque, but not so much power as this type of engine cannot operate at high speeds. Gasoline engines can generate more power as they run faster, less torque per cycle multiplied by many more cycles/minute means more power.





RPM - revolutions per minute, a measure of how fast the engine is turning.





Liters, a measure of the displacement of the engines cylinders. All things being equal, torque is generated by the combustion pressure acting on the piston face. larger pistons, more area, more force more torque more power. It's not really that simple though as the bigger engines cannot operate as fast, but more displacement is generally a great idea if more power is desired, a very bad idea if efficiency and low fuel consumption is desired.
