opoc engine, fuel efficient 2-stroke, modular powertrain technology

Why EcoMotors?


EcoMotors is a different kind of industrial company, driven by big ideas and intent on empowering change in the world.

EM is redefining how the world is powered by challenging conventions about the size, efficiency and versatility of the internal combustion engine.

Our unique opposed-piston opposed-cylinder (opoc®) engine technology enables endless potential for innovation in vehicle and machine design, giving our customers the opportunity to create distinctive value and to make meaningful, lasting changes that benefit the world.

new solutions.


The opoc® Engine

The one and only opoc®


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 result is an engine family that is lighter, more efficient and economical, with lower exhaust emissions.

Electrically Controlled Turbocharger (ECT)

Electrically Controlled Turbocharger


EM's Electrically Controlled Turbocharger (ECT™) is an exciting step in the evolution of exhaust driven turbo/superchargers for internal combustion engines. It combines a mechanical compressor and exhaust driven turbocharger into a single mechatronik solution by placing a high speed motor between the compressor and turbine wheels. The result is an independently controlled air and energy handling system in a small, low cost package.

Counter Rotating Generator (CRG)

Counter Rotating Generator


EM's Counter Rotating Generator (CRG) applies the benefits of power density, displacement on demand and compact packaging of EM’s dual-module opoc® engine layout to an electrical generator configuration. The result is extraordinary electrical performance in a highly fuel efficient, small, and quiet machine.

EM offers a solution to one of the world’s most pressing problems: how to create more power with less fuel.

We’ve done this by developing a new engine architecture we call opposed-piston opposed-cylinder (opoc) that works far more efficiently with the fuels and fueling infrastructure that we rely on today (and for many years to come).

The opoc engine architecture is also unique in that it is significantly smaller and lighter than conventional engines, it has far fewer parts, and it offers unprecedented power density. What does this mean? More miles with less fuel; more power in less space; more reliability due to fewer parts; more comfort because of less vibration. Savings in engine size and weight can be put to much better use - more cargo, more room, more capacity, more aerodynamic design - more of what you value.

We think the opoc engine is a true enabler, offering endless potential for design innovation in a broad range of vehicles and machines - empowering OEMs and end-users alike.
