Most of the internal combustion piston engines built for vehicles throughout history have pretty familiar core designs. The majority of fuel-burning vehicles sold today orient their pistons in inline ...

Remarkable innovations have been made to automotive technology since Karl Benz introduced the world to the "Motorwagen" in 1866 and Henry Ford gave rise to the American auto industry with the Model T ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

I love weird engines—give me a rotary, a turbine, or, hell, even a flat-eight and I’ll be happy. That’s why I was so excited when I heard that INNengine of Granada, Spain had produced a opposed-piston ...

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 ...

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 ...

Toyota is famous for its 2JZ engine. Mazda has the Wankel rotary. Subaru gets the "boxer." These engines have earned our respect and admiration, even with their shortcomings. Honda has its own ...
