Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the pistons in the cylinders.

There is no longer any doubt that internal combustion engines are on the way out the door. Most of us now believe that the doom of the ICE will be the electric cars, with their motors and batteries.

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...
