With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...

Small, ultra-fast, primary and “afterburner” secondary combustion events promise to deliver brake thermal efficiency as high as 69 percent. A better mousetrap? Even now, as electrification seems ...

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 ...

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 ...

Effective management of the ratio between air and fuel in internal combustion engines underpins both performance optimisation and emissions reduction. The air–fuel ratio (AFR) determines combustion ...

During a seminar focused on hydrogen-powered internal combustion engines (H2 ICE), Volvo, Bosch, Cummins, and Cespira executives highlighted the work their companies are doing to advance H2 ICE ...

As someone who has spent decades analyzing and predicting the trajectory of the automotive industry, I’ve often witnessed revolutionary moments, from the rise of hybrid technology to the advent of ...

Volvo’s hydrogen-powered trucks are being developed to provide higher energy efficiency, lower fuel consumption and increased engine power compared to conventional hydrogen combustion engine ...

The world is facing a shift toward more sustainable and eco-friendly methods of power. The construction industry has been dealing with alternative options to the diesel engines it knows and loves. But ...

Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal combustion engines developed over the course of more than century.

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.

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 ...
