Dimpled pistons might sound strange, but some say they could be the future for diesel power. We've looked at the arguments ...

The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

Piston ring end gaps matter more than you think because they manage pressure and heat, preventing catastrophic failures ...

LiquidPiston says its new XTS-210 solves the efficiency, lubrication and fuel type issues of Wankel rotary engines. This supercharged, liquid-cooled two-stroke claims 5X the power of an equivalent ...

Science isn’t fun if we don’t try to break or bend its limits, but sometimes this rebellion doesn’t work. For instance, we don’t make triangular wheels, perforated windshields, or lead pistons for ...

Ferrari is exploring a groundbreaking approach to the internal combustion engine, as revealed by a recent European patent filing. Departing from the industry-standard round pistons, this new design ...

Cylinder wall scoring can be caused by a lack of oil or oil contamination. It can be prevented through careful maintenance ...

Most of us consider piston rings little more than a necessary evil. That's probably because grinding rings is a time-consuming chore. And who hasn't accidently ground a gap too large and wasted both ...
