Canadian inventor, Kazimierz Holubowicz, has come up with an environmentally friendly and transmission-free engine based on the same mechanics as how a bullet is shot from a gun. Initial test results showed 92% efficiency.
Very promising retrofit technology with increases in fuel economy of between and two- and three-times better.

A group in Utah has been helping with prototype refinement, but recently has run into some personality issues and conflicts over intellectual property and control; which may stymie if not derail the project. Some are accusing Ron Mansfield of outright fraud. He has three felony convictions on his record.

Production prototyping nearing completion. They're looking at a retrofit solution that could double or even triple a vehicle's mileage.

- Abstract
- This presentation deals with inefficiency of vehicles. First it presents causes of the inefficiency and then solutions to flagged problems. Finally it presents a transmission free vehicle, the mileage of which exceeds 200 miles/gallon of fuel. The vehicle runs on any fuel including Hydrogen and that is possible as the vehicle uses a novel engine. The novel engine has many things in common with a traditional engine: crankshaft, piston, induction and exhaust evacuation valves, yet it is different. The engine is different since its cylinder is cooled with injections of water. Another difference is that the energy release from fuel is much faster. The speeding up of energy release is through detonations of homogenous fuel, yet a shielding of piston from explosions of fuel, prevents over excessive stress in crank and related parts, as the explosion of fuel acts rather on an additional piston floating on air pocket. Also traditional camshaft and associated gears, to manipulate valves, are replaced with electromagnetic or hydraulic actuators, controlled with an electronic controller similar to that in robotics. The engine could operate in a four stroke cycle during starting and after reaching a preset speed it switches automatically to a novel twelve stroke cycles. Its torque is independent from speed, which eliminates need to employ energy wasting transmission. Also the engine converts heat, disposed in traditional engine through cooling, into extra work. The conversion does quadruple its efficiency. Both, the elimination of transmission and extremely efficient engine contribute to mileage of the proposed vehicle. In addition, a hydrogen generation from water that uses solar panel for electrolysis enhances the mileage above 400 miles/gallon during sunny periods, since the vehicle fuels itself with hydrogen and that costs nothing.

Prototype
First prototype was destroyed from too much torque to shaft.
Prototyping is presently being done by a professional group in Orem, Utah. -- SilverThunder 12:26, 23 Oct 2007 (EDT)

A fossil fuel engine that is worth some attention
Ken Rauen provided the following comment on May 2, 2006.
Wow! This is a fossil fuel engine that is worth some attention! His basic idea is marvelous! I just wrote about long dwell time at TDC with the "tiny" engine, but this addresses the issue MUCH more elegantly! Though the inventor does not understand thermodynamics (he did not understand his son's laughter and does not know why he can get such large improvements in efficiency), he can get large improvements in efficiency within classical thermodynamics processes. Have you ever heard of experimental diesels that get 80% absolute efficiency? Mark Goldes told me about that one, a prototype made by a retired NASA engineer who made a ceramic diesel that ran on hydrogen and oxygen (no air present). I believe it. Peak engine temperature can be gigantic, and this allows the Carnot efficiency to be equally gigantic. 3000 degrees F down to 100 degrees F is a Carnot efficiency of about 85%.
Part of the problem of conventional ICEs is what happens at TDC. I think it is too confined of a space for proper utilization of the energy release in the combustion. Too much heat is lost to relatively cold metal. Allowing that space to expand rapidly and 1) convert heat quicker to mechanical energy in the "bullet" of the "gun" that is later transferred to the crank at slower speed, and 2) less restriction of the combustion process can result in better conversion of the liberated heat of combustion into useful work. Water injection has been well-documented through the years; it achieves its efficiency boost by moderating peak temperatures. Higher temperatures result in higher heat transfers to useless metal heating, so giving the burning gases more room to stay away from heat sinks is a great idea in my estimation.

Comments
Bourke Engine Also a 'Gun Engine'
Gil Walker made the following obsarvation on May 2, 2006
The article (http://pesn.com/2006/05/02/9500266_Gun_Engine/) about the gun engine is interesting. The "Bourke Engine" is a GUN ENGINE. The fuel/air mixture is detonated.
Roger Richard has built a working prototype engine, there is web video available. The efficiency of this engine is very high, can use any fuel, and replicates the HCCI engine principles.
- Reply: "I disagree. Detonation is not all that constitutes a gun engine. The inventor is using a free piston as an analog to a bullet, too. If you want to zero-in on the detonation issue, why not call it a bomb engine?" -- Ken Rauen (May 3, 3006)
Similar to pulse detonation engine
On May 3, 2006, Jeff Bennion <jbennion {at} gmail.com> submitted the following by email:
Hi Ms. Haliburton, I read the article (http://pesn.com/2006/05/02/9500266_Gun_Engine/) you posted from Bon Kulman regarding the "gun engine". [Holubowicz's] invention sounds a lot like a pulse detonation engine, currently under investigation for use in aviation. Here is a good article about if from Popular Science (http://www.popsci.com/popsci/aviationspace/e46d5b4a1db84010vgnvcm1000004eecbccdrcrd.html).
The hard part seems to be getting the timing right, and they have a huge noise issue.
- Reply by Kazimierz (May 4, 2006): Surprisingly quiet probably due to:
- 1. Explosions of fuel are contained and;
- 2. Valve opens up to release exhaust when little after expansion completed. "The little later" because expansion is below atmospheric pressure to prevent sucking in air. The better expansion is caused by much longer cylinder.
