EcoMotors International and Generac Power Systems, Inc. will jointly develop the EcoMotors opoc (opposed-piston opposed-cylinder) engine for Generac products. The agreement is designed to enable Generac to apply the opoc technology to its range of residential, commercial and industrial power generation solutions.
Since 1959, Generac has been a manufacturer of backup power generation products serving residential, light commercial and industrial markets. Generac’s power systems range in output from 800 watts to 9 megawatts and are available through a network of independent dealers, retailers and wholesalers.
The opoc engine comprises two opposing cylinders per module, with a crankshaft between them—each cylinder has two pistons moving in opposite directions. This design configuration eliminates the cylinder-head and valve-train components of conventional engines, offering an efficient, compact and simple core engine structure.
In February, Navistar International Corporation reached a development agreement with EcoMotors International in support of the company’s opoc engine architecture. EcoMotors International’s first product targeted for commercial application is a turbo-diesel version of the opposed-piston, opposed-cylinder engine.
The two primary investors in EcoMotors are Khosla Ventures and Bill Gates.
