Stroke Length based on the total engine displacement, number of cylinders and the bore. Piston Position based on the crank angle, crank radius, and rod length. Total Volume (displacement) of a Combustion Engine based on the bore, stroke and number of cylinders.

The stroke length is how far the piston travels in the cylinder, which is determined by the cranks on the crankshaft. Engine displacement is calculated by multiplying the cross-section area of the cylinder (determined by the bore) by the stroke length.

For example, if we have a bore of 4 inches and a stroke length of 3.52 inches on an 8-cylinder engine: Displacement = (4 in./2) x (4 in./2) x 3.1416 x 3.52 in. x 8 = 353.86 cubic inches.

The six-stroke engine is a advance version of internal combustion engine based on the four-stroke engine, but with additional two electric stroke intended to make it more efficient and reduce emissions. It uses fresh air for the second suction (clean air from atmosphere ) the fifth stroke.

The term six-stroke engine has been applied to a number of alternative internal combustion engine designs that attempt to improve on traditional two-stroke and four-stroke engines. Claimed advantages may include increased fuel efficiency, reduced mechanical complexity and/or reduced emissions.

The three stroke engine does not exist in reality but according to the patent this cycle can be termed as 3 stroke. In real it is a 2 stroke engine. The term “three-stroke” indicates that, to quote from the patent, “total cycle displacement (of) the engine equals approximately three expansion ratios.

The latest generation Ford Fiesta ST is finally in Australia, and contained within its snout is arguably the world’s best three-cylinder engine. It’s physically tiny and displaces just 1.5 litres, but thanks to plenty of turbo boost pressure it manages a stout 147kW and 290Nm.

the volume compression is more in 3 cylinder than 4 cylinder. this is because to meet more power generation to meet 4 cylinder engine power generation. during this more blast sound will generate inside the cylinder due to more compression volume and that is to at a time two cylinder. so more noise.

As others here have said, there is nothing inherently less reliable about a three cylinder engine vs four cylinders. However, in the real world, several factors conspire to make three cylinder engines less reliable. So right off the bat, these engines are less reliable simply because they are not BUILT to be reliable.

3 Cylinder Engines | Disadvantages

• Less Responsive Engine: The lower amount of cylinders makes the engine respond in a bit delayed manner.
• Not Refined: A 3 cylinder engine requires more work than a 4 cylinder engine due to the lower number of cylinders present.

Many new four cylinder engines can beat V8 engines for power, but other are still far behind. That said, there are still some woefully slow 4-cylinder sports cars and entry-level vehicles that really make us wish for a decent V6 or V8 under the hood.

Most four cylinder motors can withstand up to eighty horsepower worth of nitrous oxide being injected without suffering any adverse effects.

Originally Answered: Can a V6 beat a V8? That generalization, like most, is false. An engine does not “know” how many cylinders it has nor how they are arranged.

While V-6 engines often provide more engine output, four-cylinder models can often offer better fuel efficiency. The fewer cylinders and lighter engine mean that less fuel goes farther with these engines.

The engine will only have 10,000 miles left after 100 years. The motor may last a few hundred years before it needs to be rebuilt. mileage is used to calculate how long an engine will last.

While most high-end sports cars have a V-6 or V-8 under the hood, when properly tuned, a four banger can put out plenty of power and speed, often at a much more affordable price point. Shockingly, the fastest 4 cylinder car on our list has a top speed of 165 mph and the quickest zero to 60 mph time is 4.1 seconds.

4-cyl is more than sufficient for long-distance driving and speeding. Porsche 944 – Wikipedia from the ’80s still has as much or more power than than many current larger engines, and 4-cyl engines have improved since then.
