1. On what engines could it be used for?
Basic conception of Adelshin Cycle engine is the internal combustion engine without exhaust of any gases. Adelshin engine is the zero-emission engine. This engine can made on the basis of any 4 stroke Diesel or Otto Cycle engines. No any changes in 3 first strokes. Engine has the changes only in the 4th stroke, only then open exhaust valve. The basic device of new engine is so chip and simple, it looks a like a regular muffler, more of it, it could be mounted in to same place, to same nuts... Basic device is so simple inside too, but in the physical meaning this device is the vortex refrigerator, which work in the physical principals as Ranque vortex energy separation chamber. I mean this is a closed chamber, not a pipe as any mufflers.
2. Basic description - the basic operational principles.
(What is the benefit for fuel accumulating? what comes out of the exhaust? how does it consume energy?) Any regular and well know engines with this vortex device can operate in the physical borders of Adelshin thermodynamic cycle. The basis of operating process of this cycle is irreversible physical and chemical changes of working medium of engine. And the most important of them is cooling exhaust gases down to state of liquid. All exhaust gases goes thru deu point and dropt down to liquid. No more any dangerous for environmental gases, just a neutral liquid for drainage. This is the answer for "what comes out of the exhaust? " The second, most important that inside of a closed volume of cylinder and exhaust system could be generated vacuum. I mean very strong vacuum as a state of gases in the borders of very cold temperature, not a small pressure down as in intake manifold. This strong and powerful vacuum makes additional positive power stroke of piston from bottom dead point to top dead point, as a vacuum engine. The fourth stroke in Adelshin engine is the positive!!! I try to be simple here to explain my new Cycle, because this is a very difficult scientithic field, first of all. In the physical borders of pressure (p), temperature (T) and Volume (V) this cycle have absolute physical parameters as a cycle. Any well know cycles inside of it. More of it, as scientist and inventor, I have no any doubts, that this new thermodynamic cycle, as invented operating process for ICE is the greatest achievement in the history of thermodynamic.

3. What is the saving for a manufacturer in terms of cost and parts?
How long will it last? What is the maintance on it? Exhaust system doesn't need any catalytic devices. Exhaust system without catalytic is cheaper. Basic vortex chamber is the pipe with vortex nozzles. Same size as a regular muffler and the same cost for manufacturer as exhaust system without catalytic device. The most important this is maintenance free exhaust system, no any absorbers, filters and any rechargeable chemical components.

4. What is the benefit for the environment?
Most important in this case is advantages in environmental area. We are, as a people who live in the Earth now, must understand clearly where we are now and where we will. The Global Climate change can destroy our World. Most pollution to atmosphere was made and makes now motor transport. And half of it, motor transport in USA ("Environment defense" research). This is important, because now concentration CO2 in atmosphere is 278 prm, plus 2 prm on every year, and irreversible changes will be in the border of 300 prm just a little later- And no any choice to move it back... Therefore, simply to stop exhaust of gases from engine, its not to decide only one technical problem in only one motor industry--it means more- to safe the Life in the Earth.
