Quick Answer: Why are some engines more powerful?

Why do some engines make more power?

Air comes in, gets “exploded” by a spark and fuel and the expansion of the air in that explosion causes pistons to move to create “power”. Everything being equal the bigger the air pump, the more power it is going to produce, and that’s not number of cylinders, it’s volume of air that the engine “holds” at it’s max.

Why are new engines more powerful?

Modern engines are more powerful

People are more concerned with fuel economy now than when cars were new, but they’re also more concerned with engine power because modern cars are a lot heavier. So today’s engines are more powerful than their predecessors – even compared to engines that are just a few years old.

Which engine is most powerful?

Developed by Wärtsilä Corporation, the 14-cylinder Wärtsilä RT-flex96C engine is also the world’s most powerful engine with an output of 80,080 kW (108,920 bhp). The 14-cylinder Wärtsilä RT-flex96C engine is a major breakthrough for ship propulsion.

Does more pistons mean more power?

Generally speaking, it is easier to make more power with more cylinders. If one has two engines of similar displacement, the engine with more cylinders will generally produce more power.

Why do smaller engines rev higher?

Lower piston speeds means less stress on the connecting rods and crankshaft as well as acceptable flame propagation speeds, allowing the engine to rev even higher. … Formula 1 engines and motorcycle engines often have very high bore/stroke ratios, allowing for higher engine speeds (and thus more power).

Why did old v8s make so little power?

Restricted port design means restricted flow, and that translates to less power, especially at high rpm, when the engine is trying to flow large amounts of air and fuel through the engine. High torque at high rpm is where big horsepower numbers are made, and high flow is necessary for high torque at high rpm.

Who had the first V8 engine?

Frenchman Leon Levavasseur was a 39-year-old inventor in 1902 when he took out a patent for the first V-8 engine he called the Antoinette. The V8 since then has become the most reliable and efficient internal combustion engine to power automobiles and to see extensive use in power boats and early aircraft.

Is there a V24 engine?

A V24 engine is a 24-cylinder piston engine where two banks of twelve cylinders are arranged in a V configuration around a common crankshaft. The majority of V24 engines, however, have been “dual V12” engines where two separate V12 engines are placed in line with each other.

What is the fastest engine in the world?

The most powerful version of the Agera, the Agera RS, became the world’s fastest car on November 2017, when Koenigsegg hit an average speed of 277.9 mph.

Koenigsegg Agera RS: 278 MPH.

How much horsepower does a 350 bored 30 over have?

030″ over 350 is actually a 355 cubic incher, and at 1HP per cubic inch for a mild build, we would get 355 HP.

Why do long stroke engines have more torque?

Under Square or Long-stroke Engine

‘It’s because of the higher peak piston acceleration. A long bore engine, as the name suggests, has a longer cylinder. These engines reach their peak torque at a lower rpm when compared to a short-stroke engine. … These engines have a higher volume to surface area ratio.

Why do Harleys make so little power?

Cruisers, like Harley Davidson bikes, are slower than sports bikes because they have push-rod valve trains and are air-cooled, and can therefore not operate at high engine RPMs to develop lots of power. … The ‘real’ bikers in the forums believe cruisers are slow because the owners don’t know how to ride.
