One Stroke Engine

A inventor named bourke invented one stroke engine called bourke engine 30.

Here's about it;

Bourke 30

Built in 1954. This is Russell's first 30 cubic inch, 30+ HP production engine built for public use. The claims made, except for the unusually high rpm's or the workability of extremely high compression ratios, are true based on real world tests. The key to it's much higher efficiency is simply increased time at Top Dead Center 'TDC'.

Back in the 1940's Russell Bourke set out to solve various problems with the conventional engines of that era. During his career as an instructor on internal combustion engines he soon ended up discarding many pre-conceived notions, fixed ideas and incorrectly duplicated theories of how to create the same end result as a steam engine using pressure as the prime mover by converting hydrocarbon based fuels to create pressure against a piston driving it downward in a cylinder and converting it into rotary motion.

The first basic and workable theory was in order to create the needed pressure against a piston, combustion of hydrocarbons and air in an enclosed chamber was mandated! In order to accomplish real work it was theorized that 4 separate cycles. 'INTAKE' of air and fuel, 'COMPRESSION' thereof, spark or pressure ignited expansion of those gasses ' POWER' and finally removal of the spent gasses, 'EXHAUST' was necessary.

Long ago, Dr. Otto came up with the first practical working engine based on this theory which was a 4 stroke type. It completed 4 cycles in a very literal way in that it had an INTAKE stroke, a COMPRESSION stroke, a POWER stroke and finally and EXHAUST stroke. Do you see the literal translation? The 4 Stroke Cycle was born.

The combustion chamber had to be valved in order to enable the cylinder to admit air and fuel and to emit spent gasses and it needed a crankshaft to drive things. There was quite a bit of parasitic power robbing equipment added to accomplish the above complete cycle. Anyway, the first internal combustion piston engine was born and basically it hasn't changed one bit since!

Ever since then we have been basically stuck with the Otto cycle to drive anything that requires a 4 stroke/cycle diesel or gasoline engine. The problem isn't so much in Dr. Otto's interpretation of original theory or Dr. Diesel's decision to stick with what works.

This includes 2 stroke and turbine engines as well. They are although much simpler and able to yield more power per pound of weight, still prone to similar limitations.

Thermodynamically speaking they are flawed relative to their stoichiometric limitations and their complete inability to achieve even a hint of adiabatic efficiency.

Although they do work, none of these engine types are capable of adiabatic operation in that their efficiency is gauged based upon fuel rich stoichiometric ratios.

Regardless of an engine, be it 2 stroke, 4 stroke or turbine type, they are all inefficient stoichiometric engines in that they emit harmful waste products into the atmosphere! They needlessly pollute our world due to an incomplete combustion process with a great deal of lost heat energy that could and should otherwise be put to work!

Regardless of that and to be fair, It remains a fact that conventional engines have worked well for decades and kept the world chugging along faithfully for a long time. But at what cost?

We are all seeing the cost now as Russell Bourke predicted decades ago and tried to help prevent! I don't have to tell you what that is as you wouldn't be reading this now if you didn't know or at least suspect that something can be done about it! Yes, the effect is overall environmental degradation due to improperly and incompletely converted hydrocarbons and other toxic substances and gasses!

The work engineers and chemists have done, their innovations as well as improvements of conventional engines and hydrocarbon fuels of all types are greatly acknowledged and appreciated. From my perspective, engineers are generally extremely bright intelligent people who solve problems and create! The greater majority of them have a passion for helping their fellow inhabitants live better, take care of and preserve our natural resources.
