Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

It is the only diesel engine operating on the road capable of meeting CARB’s 2027 regulation, which requires a 90% reduction in emissions of NO x compared to current standards. The catalyst light-off mode delivers the capability that allows Achates to manage extremely low engine-out NO x and also very high exhaust gas temperatures.
