Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging. Scavenging continues until a 230° crank angle, at which time the exhaust ports close.

Projected conditions for internal combustion engines in 2025 push light-duty engine exhaust temperatures into the low end of gas turbine regimes, Haynes said. The increasing piston, cylinder, head, exhaust valve and turbocharger temperatures represent significant structural materials—and cost—challenges.
