Why do same size engines have different horsepower?

Why do same size engines have different horsepower?

The main reason is that the engine is dependent on the intake and exhaust routing to make maximum horsepower. A more restrictive airbox and ducting on the intake side and more restrictive exhaust will reduce peak hp. Also, there could be different tuning parameters in the ECM .

Does bigger engine mean more horsepower?

The bigger the engine size, the more space there is for air and fuel inside it. This largely explains why modern, small engines can often produce more power than older, bigger engines. The amount of power produced by an engine is usually quoted in horsepower.

Is a 2.4 liter engine a V6?

Most cars have four, six, or eight cylinders. If the car has four cylinders, called the straight-four engine, all of its cylinders are designed to be in a straight line. This configuration is common to cars that have a 2.4-liter engine displacement. An engine of a car with six cylinders is called a V6 engine.

Why do smaller engines rev higher?

Smaller engines have to rev up more to achieve the same power as larger engines. Every cylinder has it’s own reciprocating weight in the piston and connecting rod. The length of the stroke affects how high it will rev.

What is the difference between BHP and CC in an engine?

i.e more the more mass ,more cc is required ,to produce more bhp. Eg:- in bigger engines like the ones in truck ,they are big cc but produce less bhp. Less cc in bikes but more bhp. These bhp and cc thing is inter-related and only a true expert can explain it.

Do all cars have the same cc engine but produce different power?

Many cars have same displacement (CC) engines but produces different power. But that depends how engine is tuned up. In India cars are tuned up to get more fuel efficiency/ mileage but some brands focus on the power output hence they tune up engine to get more power.

Why do trucks with the same engine have different engine options?

A truck with the same engine would get a more torque oriented cam, manifolds, and possibly head (along with a more appropriate ECU). And an automaker may detune other vehicles using the same engine as their top vehicle in order to get people to buy their top vehicle.

Do all engines with the same refinement levels produce the same power?

Engines with same refinement levels aren’t designed to produce same power, some are biased towards torque while others towards power. (hope you are aware of torque-power relation). Let me explain this with an example, Maruti Alto K10, 1000cc inline four producing roughly 65bhp and 90N.m torque (can’t recall exactly, but approx).
