Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet

Green Car Congress

This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process.

Fairbanks Morse Engine and Achates Power team up on opposed-piston engines

Green Car Congress

In the early 1990s, Fairbanks Morse Engine introduced dual-fuel combustion technology that reduced NO x exhaust emissions to levels previously achievable with only lean-burn spark-ignited gas engines. Achates Power began modernizing opposed-piston engines in 2004, inspired by the record-setting Junkers Jumo 205 diesel aircraft engine.
