Thermal efficiency is over 40%, they say. Avadi says its engine can replace “virtually anything that uses an internal combustion engine. Anywhere from lawn equipment and scooters to automotive ...

The incident at the Dundee Engine Plant follows the death of a worker last year at the Stellantis Toledo Assembly Complex. The incident was described as a workplace accident, but details were limited.

I have already written about LiquidPiston and its XTS-210, but Avadi's idea is even more striking: it is a reciprocating engine that works as a rotary. Imagine an ICE with a single piston.

From the patent drawings, it appears the engine uses a mechanism on the crankshaft to vary the stroke of the piston as it proceeds through the combustion cycle. If the patent diagrams are anything ...

Essentially, it’s a six-stroke engine that relies on a different stroke length for one of the strokes. The first three strokes are very like those in a four-stroke: intake, compression ...

Most people are familiar with the importance of oil for the internal combustion engines that power our modern vehicles. The petroleum-based fluid is designed to provide lubrication to the vast ...

If you have a basic understanding of how a turbocharged engine like the 2023 Toyota GR Corolla's souped-up three-cylinder works, it's not hard to figure out that they pose reliability issues you ...

But reinventing piston-powered engines? Not so much. Well, an American company called Avadi is undaunted by all that EV momentum and doing just that, reinventing the piston-powered engine ...

After launching a modern pulsejet engine for UAVs back in March, Wave Engine Corporation announced this week that it's delivered the first units. The loud, pulse-combustion fire-breather is ...
