An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

Ferrari has signaled a willingness to challenge one of the most fundamental assumptions in engine design by filing a European ...

For as long as internal combustion engines have existed, pistons have been round. This wasn't necessarily because circular shapes were optimal for performance. It was simply the easiest and most ...

As the industry’s transition to electrified vehicles continues, albeit at a slower pace, you wouldn’t think many would be working on developing more sophisticated internal-combustion engines. Oh, to ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

1. EcoMotors is developing high-efficiency engines — specifically the unique opoc (Opposed Piston Opposed Cylinder) engine — for use in cars, light trucks, marine applications, agricultural vehicles, ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

This file type includes high resolution graphics and schematics when applicable. Automotive engineers are concerned with weight-to-power ratios when designing vehicles. While light-weighting is a ...

Over the roar from a 110-cc, two-cylinder engine, Pinnacle Engines founder James Cleeves (nicknamed Monty), pointed out a window in the block. "You can see the cylinder sleeve moving for the intake ...
