Mazda RX-7/RX-8 how many engines are made each year, compared to all auto production? are they pushing trucks? they are merely exotic. with seel problems. like having an engine with square pistons. Role on the liquid ring engine or the scroll with no pistons or rings.

There is a similar looking engine in the Science museum in London, which was removed from a WW 2 German Aircraft. It was a high compression Diesel. Being flat, it fitted into the wing improving the Luft flow thus increasing the furrshluggerindurger. However, I seem to remember another innovative "Hardly any moving parts engine" called the Wankel which was heralded as being extremely wondrous, Whatever happened to it's final development? and would it run on a gasifier product?

The Fairbanks Morse OP engines that propelled the WWII subs were that design. There are still a few cogen plants around today that use those engines as well in dual fuel configuration, but they were supercharged, not turbocharged. JAMES T. LEACH, P.E.

Hi Pete Eco motor is innovative modern IC engine evolution You can see video , animated pictuures too http://www.ecomotors.com/ The opoc® engine comprises two opposing cylinders per module, with a crankshaft between them -- each cylinder has two pistons moving in opposite directions. This innovative design configuration eliminates the cylinder-head and valve-train components of conventional engines, offering an efficient, compact and simple core engine structure. The result is an engine family that is lighter, more efficient and economical, with lower exhaust emissions. EcoMotors' opoc® engine has a number of distinct advantages over traditional internal combustion engines. The opoc® engine has very high power density of nearly one horsepower per pound resulting in an unprecedented lightweight and compact engine. The opoc® engine is perfectly balanced enabling stackable power modules. This unique modular displacement capability is one of the long standing, but elusive goals of engine engineers' quest for high efficiency. In addition, it also results in much less NVH than a conventional engine of comparable power. Its elegantly simple design allows for low cost, efficient manufacturing and increased operating durability: · 50 percent fewer parts than a conventional engine · Straightforward assembly · No cylinder heads or valve-train · Uses conventional components, materials and processes "Consistent with our leadership strategy, Navistar continues to seek innovative products which differentiate us from the marketplace, while others embrace the status quo," said Eric Tech, president, Navistar Engine Group. Power Density The internal combustion piston engine has been the primary means of automotive propulsion for more than a century. Today, thousands of engineers around the world are hard at work trying to improve this 19th century invention. Some are striving to make incremental gains; some are hoping for a breakthrough. For all of them, one measuring stick is the "acid test" for any engine -- power density. As greater power density is achieved, a range of critically important attributes will result, including: · Lower weight · Smaller size · Lower material costs · Lower friction · Greater fuel efficiency · Lower emissions · Lower heat rejection Electrically Controlled Turbocharger EcoMotors' intellectual property also includes an electrically controlled turbocharger technology which incorporates an electric motor in the turbo assembly to regulate boost pressure resulting in a long list of unique advantages: · Improved combustion efficiency to meet emissions · Electrically controlled variable compression ratio · Improved vehicle fuel economy · Enhanced vehicle drivability due to improved low-end torque · Eliminates Turbo lag · Waste heat recovery by generating electricity On Tue, Aug 9, 2011 at 3:09 PM, Pete & Sheri <[email protected]> wrote: What is a two piston ecomotor?
