LEMONT - Researchers at the U.S. Department of Energy's Argonne National Laboratory have joined forces with Caterpillar Inc. to develop a potential new piston design for heavy-duty diesel engines.

Perhaps the biggest challenge facing the diesel engine business today is “re-orienting” design efforts away from a focus on exhaust emissions to fuel economy, performance, and component integration – ...

Diesel engines are some of the simplest combustion concepts in use today, with a design that has not changed much in half a century. But what has changed is the complexity of the systems that surround ...

Across more than a century of automotive history, a handful of engines have earned reputations for surviving abuse, neglect, and astronomical odometer readings. The most durable designs share a common ...

A "cool flame" may sound contradictory, but it's an important element of diesel combustion—one that, once properly understood, could enable better engine designs with higher efficiency and fewer ...

Some engines earn a reputation not just for power or refinement but for an almost absurd ability to survive neglect, abuse, and high mileage. When mechanics talk about designs that are “nearly ...

THE Diesel engine has now been constructed successfully in. so many different types that any book on its design which is not restricted to one particular line of development must almost necessarily ...

Rocket engines and the internal-combustion cycle get a remake, thanks to engineering ingenuity. When it comes to engines, smaller and more powerful are always better. Throw in less expensive and ...

Sandia National Laboratories researchers (left to right: Nathan Harry, Christopher Nilsen, Drummond Biles, and Charles Mueller) show off their prototype of ducted fuel injection module for diesel ...

A team of engineers at the University of New South Wales (UNSW) in Sydney has figured out a way to run a diesel engine on a mix of diesel and hydrogen, dramatically lowering its emissions. Why do we ...
