8 Stroke Engine
ABSTRACT

The quest for an engine which having the same or more power with higher fuel efficiency than the existing ones has started before many years. As a result of all these researches a new engine concept is formed, which is a six stroke engine. Lot of research works are conducting on this topic nowadays and already six types of six stroke engines were discovered yet. Of these the resent developed three six stroke engines, i.e., Beare head, Bruce crowers and Velozeta’s are undergoing tremendous research works.

During every cycle in a typical four stroke engine, piston moves up and down twice in the chamber, resulting in four total strokes and one of which is the power stroke that provides the torque to move the vehicle. But in a six stroke engine there are six strokes and out of these there are two power strokes. The automotive industry may soon be revolutionized by a new six-stroke design which adds a second power stroke, resulting in much more efficiency with less amount of pollution.

INTRODUCTION

The term six stroke engine describes two different approaches in the internal combustion engine, developed since the 1990s, to improve its efficiency and reduce emissions

In the first approach, the engine captures the waste heat from the four stroke Otto cycle or Diesel cycle and uses it to get an additional power and exhaust stroke

    Just to give an idea of the level of significance of such invention to the world, especially in the motorcycle world, all three Grand Prix Classes have been won by those with two-stroke engines for ‘as long as people can remember’. Nearly all Formula One drivers learnt their craft driving two-stroke Karts and most board powered boats and personal water craft are still cruised or races under two-stroke power. (ref 13) The two-stroke engine was then improved by Joseph Day, an English engineer who designed the Valve-less Two-Stroke Engine in 1889. Originally there were two flap valves in Joseph Day’s design: one in the inlet port where usually a reed valve is found in a modern two stroke engine, and one in the crown of the piston. They were then removed when the engine was modified after coming up with the idea of transfer ports a few years later with the aid of one of Joseph Day’s workmen, Frederick Cock, who made the modification which allowed the skirt of the piston to control the inlet port and do away with valves, giving rise to the classic piston ported two stroke. The two stroke engine is much lighter than its four stroke counterpart. It does not compose of any valves and therefore requires much less lubrication than the four-stroke engine does. It can also be constructed in a…

    Diesel and gasoline are two main sources of energy for today’s cars. Both are from the same source, crude oil but are refined differently. These sources also have different chemical properties and each are burned in different ways. Diesel is easier to refine than gasoline, contains more energy than gasoline and the vehicle’s engine combustion process is more efficient. Diesel is denser and contain’s 11% more energy. It is more efficient in converting mechanical work because it operates at higher compression ratios and temperatures. Large trucks and agricultural vehicles have diesel engines to take advantage of this higher efficiency.…

    should cars be efficient

    Efficient has raised a question in the auto industry; by questionable about whether the world can support the efficient in cars. If a single driver in a car that is able to carry 4 to 6 for a distance of 2 to 300 miles is not so efficient when we need only commute 30 miles each day to work and back. One study is the “heat engine” which is the internal combustion engine. This efficient vehicle can have more of efficient. Cars and trucks account for more than 60 percent of U.S. oil consumption and more than 25 percent of domestic carbon pollution, environmental statistics show. The auto industry has held on to cleaner burning fuels, more efficient engines and advanced battery technologies for gasoline-electric hybrids and full-electric cars that produce few to no emissions. Automakers are growing to boost efficiency, and many cars on the road already meet or exceed the 2016 targets. General Motors and Japan 's Nissan are racing to roll out the first mass-produced electric cars later this year and other manufacturers have designs in the pipeline.…

    Six Stroke Ic Engine

    In the first approach, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air as the working fluid for the additional power stroke. The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. There are two power strokes: one with fuel, the other with steam or air. The currently notable designs in this class are the Crower Six-stroke engine invented by Bruce Crower of the U.S. ; the Bajulaz engine by the Bajulaz S.A. company of Switzerland; and the Velozeta Six-stroke engine built by the College of Engineering, at Trivandrum in India.…
