Heat transfer in internal combustion engines governs both performance and durability by controlling temperatures within the combustion chamber, cylinder walls, piston crown and cylinder head.

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel's potential energy while the rest is lost as heat through exhaust. Now, a study demonstrates how to convert exhaust ...

In this video, we conduct a detailed comparison of petrol (spark ignition) and diesel (compression ignition) engines, ...

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 ...

Internal combustion engines have long received flack for how wasteful they are. And while you can't argue about how inefficient they may be, the truth is that internal combustion has led the way for ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...

From heavy-duty trucks and agricultural machinery to shipping fleets, aviation, and power generation, internal combustion engines STILL remain indispensable to both global infrastructure and mobility.
