> 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:

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:

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:

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:
