San Diego’s Achates Power says today it has raised $35.2 million in a Series C round of venture financing to advance its opposed-piston engine, saying its cleaner and more fuel-efficient design is gaining traction throughout the automotive industry.

Achates says its design weighs about a third less than a conventional engine, requires less machining and assembly, and is less expensive and easier to manufacture.

After developing and demonstrating the advantages of its design over the past nine years, Johnson said the company is moving into much more of a structural commercialization phase, in which Achates is working closely with customers to
