The story of how Honda developed an oval-piston race engine that ultimately failed but still made history along the way.

The first recognizable internal combustion engine was developed by Nikolaus Otto in 1861. Since then, the gasoline-powered engine has evolved immensely. However, the principles that underlie how ...

Ferrari has signaled a willingness to challenge one of the most fundamental assumptions in engine design by filing a European ...

The piston ends its downstroke and begins moving upward, compressing the air/fuel mix until combustion happens and the whole cycle begins anew. This means that the high torque efficiency of the ...

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 ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both ...

General Atomics Aeronautical Systems Inc. said Tuesday the transaction strengthens its capabilities in high-performance propulsion systems and reflects its commitment to advancing propulsion ...

The Toyota 2GR-FKS is considered to be quite a reliable motor, but there may be trouble brewing within some older examples. Early 2GR-FKS V6 engines may suffer premature piston and cylinder wear. Main ...

A straight-twin engine, also called an inline-twin or parallel-twin, is a two-cylinder setup where both cylinders sit side by side, upright, and share a single crankshaft. It's the simplest way to ...
