When we think of a typical four stroke internal combustion engine, we think of metal. And for any type of longevity or performance, that’s certainly the right choice. But [Integza] wanted to see what ...

Volkswagen isn't reinventing the way your internal combustion engine works. The automaker has, however, created a new twist on the Otto cycle that's a revised version of the Atkinson cycle. Your ...

The demise of the internal combustion engine has been greatly exaggerated, or so Mercedes-Benz thinks. The company’s position stems from empirical observation, based on all rational evidence: Internal ...

Quantum work: A quantum thermochemical engine operating in an Otto cycle with a weakly interacting 1D Bose gas as its working fluid. The initialization and exhaust strokes are performed by coupling ...

Real-world engines have to trade off between efficiency–how well they convert heat into work–and power, how quickly they accomplish this conversion. Generally, the more powerful an engine is (the ...

AMONG the names of the hundreds of inventors through whose individual efforts the internal combustion engine has reached its present state of efficiency, that of Nikolaus August Otto will always be ...

Quantum mechanics could be used to improve the efficiency of heat engines, according to Marlan Scully of Texas A&M University in the US. Scully has calculated that exhaust energy from an engine could ...

diagrams shown opposite. In location 1 the piston is at the bottom of the cylinder (max. volume; BDC) and the inlet valve has just closed. From: Moran & Shapiro, "Fundamentals of Engineering ...
