Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions ...

The process of transforming a barrel of oil into these products is managed in the discipline of chemical engineering, through which high-temperature vessels (called “columns”) allow fluids to be split ...

DTNA 2027 engines lineup expands with Cummins B6.7 Octane, new X10 platform, and Detroit Gen 6 diesel engines.

What makes a diesel engine different to a regular gas engine, and is one better than the other?

Caterpillar is putting that century-old design to work in its heaviest tracked dozer yet – and the efficiency gains are incredible.

American drivers notice soaring gas prices. But another fuel – diesel – is also on the rise, and at a much faster pace.

Inside a diesel engine's cylinder, compressed air raises the temperature to ignite injected fuel, and the resulting force drives pistons to power the vehicle's main gears. Chief to this combustion ...

Gasoline rarely freezes, usually becoming waxy between -40°F and -200°F; issues often involve water. Diesel fuel "gels" at 10°F to 15°F, with winter blends and additives preventing gelling. Prevent ...

When the temperature drops into the negatives, your vehicle faces several challenges. Cold weather thickens engine oil, saps battery power, and causes tire pressure to plummet. However, aspect of ...

DAYTONA BEACH, FLORIDA - FEBRUARY 14: William Byron, driver of the #24 Raptor Chevrolet, drives through the garage area during practice for the NASCAR Cup Series Daytona 500 at Daytona International ...

While diesel engines don't need spark plugs, they do need air ventilation for proper combustion. This is a problem for vessels traveling underwater, such as submarines. Yet diesel submarines exist and ...
