In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single ...

The Achates Power opposed-piston engine I saw in the Calstart webinar was a heavy-duty diesel for use in 18-wheelers. The 10.6-liter three-cylinder (with six pistons) makes 400 hp at 1700 rpm and ...

Boxer engines may not be that popular in cars, but they're a common sight in smaller aircraft. But why do these small planes use horizontal engines?

Hydrogen-powered opposed-piston engine can potentially power hard-to-electrify vehicles for long-haul transit. Invented more than 100 years ago, the opposed-piston engine had its heyday during ...

The engine you see here has three opposed-piston engines in a chain, forming a triangle. This setup made 3,700 hp when turbocharged. A much simpler bank of six cylinders (12 pistons) could power ...

Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group, a collaborative forum to advance sustainable ...

Opposed-piston engine technology has been touted as a possible alternative to conventional engine designs for years. Now, opposed-piston engine developer Achates Power reports that its 10.6L ...

The opposed-piston concept is hardly revolutionary; the Fairbanks-Morse 38 1/8 has been powering marine vessels since World War II. French engineer Eugene Brillié was designing opposed-piston ...

That’s why I was so excited when I heard that INNengine of Granada, Spain had produced a opposed-piston engine that packed a pretty powerful punch in an extremely tiny package. There’s no ...

Leveraging years of research and development and more than 500 hours of dynamometer testing, Pinnacle Engines’ ultra-efficient engine is based on a four-stroke, spark-ignited (SI), opposed ...
