This development in turbocharger technology incorporates an electric motor into the turbo assembly. In essence, it provides a supercharger, driven by the electric motor, as an adjunct to the exhaust-driven turbocharger. Boost pressure can be created by the electric motor, the turbocharger, or both. The ECT effectively eliminates turbo lag because the electric motor provides much faster turbine response, and also provides boost when there is low energy from the exhaust flow. The motor is actuated by an electronic controller, which can be integrated with the engine control unit. When it is being spun by the turbocharger, the electric motor acts as generator, producing electricity.
This patented design creates a ground-breaking internal combustion engine family architecture that will run on a number of different fuels, including gasoline, diesel and ethanol. The opoc's new opposed piston-opposed cylinder direct gas exchange operation provides the well known emissions benefit of 4-cycle engines, the simplicity benefits of 2-cycle engines, the power density of the less well known opposed piston engine, and the extraordinary developments in computer and thermodynamics all tied together in a new and proprietary engine architecture. It 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. Here you can see this revolutionary engine in operation, which helps to illustrate the simplicity, elegance and compactness of its design.
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. Why is this so important? Because, if you achieve greater power density, a range of critically important attributes will result, including:
