What does a five stroke engine have that makes it more efficient?

The goal of the five-stroke engine is to have higher efficiency with lower fuel use. To increase efficiency a secondary cylinder is added as an expansion processor to extract more energy from the fuel. The exhaust gas from the two HP work cylinders is fed into a one larger central low pressure (LP) expansion cylinder.

Is there a six-stroke engine?

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.

Is there such thing as a three stroke engine?

A three-stroke internal combustion engine completes a complete combustion cycle of exhaust, intake, compression, ignition, and expansion within a single revolution of a crankshaft by a single stroke of a first piston and a single stroke of a second piston within a single cylinder.

What are the advantages of a 4 stroke engine?

Upon completion of the 4 events, the cycle is complete and ready to begin again. 4-stroke engines deliver a good balance of power, reliability and efficiency. When it comes to emissions, 4-strokes separate each event mechanically, which reduces unburned fuel emissions.

Do all cars use the four-stroke cycle?

Nearly all cars use the four-stroke cycle. Four-stroke engines carry several benefits, including improved fuel economy, more durability, more power and torque, and cleaner emissions. However, compared to two-stroke engines, they are more complicated and expensive to make, and require the use of valves for the intake and exhaust of gases.

What are the steps of a 4-stroke engine?

On a four-stroke engine, there are four steps the engine takes as it burns gasoline: intake, compression, power, and exhaust [source: CompGoParts.com ]. These steps all occur when as piston moves up and down two times.

What is a 2 stroke engine used for?

2-stroke engines are also common, however they do not power cars or light trucks. 2-strokes are found on small engines, such as dirt bikes, chainsaws, outboard marine engines, lawn care equipment, scooters and mopeds, and so on.
