# Is there any 6 stroke engine?

## Is there any 6 stroke engine?

TWO EXTERNAL ELECTRIC STROKE 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.

## What is the advantage of a longer stroke engine?

Now, while the power produced by a typical long stroke engine is relatively less, it has its own advantages. These engines produce a much healthier torque at the lower range of the rev spectrum lending themselves to torquey, lazy revving machines very well.

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.

Why is the intake stroke important?

Intake stroke: the intake stroke draws air and fuel into the combustion chamber. The piston descends in the cylinder bore to evacuate the combustion chamber. When the inlet valve opens, atmospheric pressure forces the air-fuel charge into the evacuated chamber.

### What are 6 stroke engines used for?

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.

### How do you calculate engine stroke?

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.

How many types of stroke engines are there?

Types of power cycles The thermodynamic cycle used by a piston engine is often described by the number of strokes to complete a cycle. The most common designs for engines are two-stroke and four-stroke. Less common designs include five-stroke engines, six-stroke engines and two-and-four stroke engines.

How does a six-stroke engine work?

In a six-stroke engine prototyped in the United States by Bruce Crower, water is injected into the cylinder after the exhaust stroke and is instantly turned to steam, which expands and forces the piston down for an additional power stroke.

## What are some applications of six-stroke engines?

6 stroke engines involve two additional strokes where water/steam or compressed air is exerted into the combustion chamber and is allowed to expand due to the heat of the combustion chamber. This causes the piston to move down and hence acts as a secondary power stroke. However there are a few drawbacks:

## How many times does a six stroke engine go up and down?

The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. These designs use either steam or air as the working fluid for the additional power stroke.

Who was the first person to invent a six stroke engine?

Leonard Dyer invented a six-stroke internal combustion water-injection engine in 1915, very similar to Crower’s design (see below).

How does a single stroke engine improve fuel efficiency?

In the single-piston designs, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to drive an additional power and exhaust stroke of the piston in the same cylinder in an attempt to improve fuel efficiency and/or assist with engine cooling.
