Power management company Eaton announces it will supply its TVS air pump to manage airflow in the demonstration of the Achates Power two-stroke Opposed-Piston Engine (OP Engine) at the Internal Combustion Engine Fall Technical Conference in San Diego.
Eaton’s TVS air pumps currently supply airflow to several Achates OP Engine prototypes, which will gradually transition to a new Eaton TVS air pump currently under development. Fundamental to the OP cycle is the air pump, which is the key air management technology and an enabler of the engine’s outstanding performance.
The on-road demonstration project is funded by a $9 million grant from the California Air Resources Board (CARB) to CALSTART, an organization supporting clean transportation that is overseeing the project. The OP Engine will power the CALSTART Class 8 commercial truck, which is expected by CALSTART to achieve a 90% reduction in NOx and a 15–20% fuel efficiency improvement.
“Eaton is pleased to contribute to this promising project that has the potential to dramatically reduce emissions and increase fuel economy in diesel engines,” says Mihai Dorobantu, Director, Technology Planning and Government Affairs, Eaton Vehicle Group. “Eaton’s TVS air pump, with its ability to produce a precise, controllable airflow, is the ideal solution for the OP Engine.”
Eaton’s TVS air management technologies will provide the precise airflow needed for the OP Engines. The soot-resistant TVS air pump represents a significant step in technology maturity toward a robust product.
