how to know about engine hoursepower Rating?

Question

people say that my car is having 1300cc engine so what does it mean send me with mathimatical solution

Answer 1

Too many variances that you have to know to come up with a one size fits all math equation.

Besides cubic inches or cubic cc's, there is the physical design of the motor and heads and camshaft(s). Every motro design will change the hosepower as will the camshaft and valves and combustion chamber of the heads. Some pistons, for example, have a round head and fit tighly into a cylinder head that is cut to receive it. Some have flat topped pistons and some old models had concave pistons. The number of intake and exhaust valves makes a difference and the duration of the lift from the camshaft makes a difference. The exhaust system adds to or takes away from the "usable" horsepower, too. HP that makes it to the drive train and isn't wasted on back pressure and engine accessories and so on.

If you are talking about a modern car, an engine diagnostic test can determine your HP output. What the window sticker says is not always the actual HP on that car. This is a computer estimated HP (just like the gas mileage) and real world is different.

Good Luck!

Answer 2

There is no certain mathematical solution to derive horsepower from engine size. You need to know cylinder filling efficiency, air flow thru throttle, fuel flow capacity, etc etc
Find a service manual for your car. It should help you identify your engine based on car model & year. Should be a chart that lists factory horsepower ratings. Your public library may have those manuals in their reference section.

Answer 3

Could you clarify your question?
Are you asking how to figure the horsepower of your engine?
There are several factors that go into calculating hp, so to answer, the question should be a little clearer.
Thanks!
