Opposed piston engines
Another technology we have been working on is the opposed piston engine.
These engines provide a promising alternative architecture to conventional gasoline vehicles, potentially offering enhanced fuel efficiency, lower CO2 emissions and lower pollutant emissions than conventional gasoline vehicles.
Here’s how it works:
The engine uses two pistons per cylinder, working in opposite reciprocating motion, eliminating the need for the cylinder head and valve-train components – reducing weight, cost and energy loss in the engine due to heat loss and friction.
This unique prototype reduces heat losses and overall friction, making the engine more efficient.
When operated in a two-stroke architecture, the opposed piston design can potentially deliver better fuel economy and lower CO2 emissions, while achieving significantly lower NOx emissions, than conventional gasoline vehicles.
Together with our partners, we are making great strides towards realizing the potential of opposed piston engines for commercial transport.
