Diesel engine producer Navistar has announced an investment into EcoMotors, a start-up hoping to market a revolutionary new engine design.

EcoMotors International is no stranger to receiving investment funds from well-known outside sources, as several months ago Leftlane reported on a $23.5 million investment by none other than Bill Gates and billionaire Vinod Khosla into the small firm.

Now, it appears that the opposed-piston, opposed-cylinder (or opoc) design has garnered attention from someone actually in the business of building engines - Navistar International. According to a report by FleetOwner, Navistar has partnered with EcoMotors to co-develop a turbocharged diesel engine that they hope to use for production vehicles in the relatively near future.

As previously covered, the advantages to an Opoc motor, as explained by EcoMotors, are that they design is both 50 percent simpler in terms of parts used, and uses 50 percent less fuel, all the while being lighter and capable of reducing emissions. The design can supposedly be expanded for both small, medium and large-sized engines, and can be made to run on several fuel types, including gasoline and diesel.

"[This technology] can provide not only rapid payback but also economic and carbon benefits to large segments of the world's population without the need for subsidies or massive infrastructure investments," said Vinod Khosla, investor in EcoMotors and head of Khosla Ventures.

"Among next-generation propulsion systems, the opoc engine is broadly applicable and can provide lower carbon emissions than almost any other technology," he added. "We are delighted that Navistar has recognized the game-changing promise of opoc."
