Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines ...

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...

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 ...

For hundreds of years of human history, the invention that has defined our ability to travel, explore, and expand our boundaries has been the combustion engine. This hallmark of mechanical development ...

Combustion efficiency in internal combustion engines refers to the proportion of chemical energy in the fuel that is converted into useful mechanical work. Attaining high combustion efficiency is ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

In-cylinder pressure measurement forms the foundation of advanced combustion control by providing direct insight into the thermodynamic processes within an engine cylinder. Accurate pressure traces ...

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.

Automakers once bet big on bizarre ideas—from swirling airflows to variable compression—and the results were as fascinating as they were short-lived. Automotive engineers have invested countless ...
