Ignition timing is easily the single most important tuning adjustment on an internal combustion engine and yet the concept of ignition curves continues to be elusive for many enthusiasts. Yet all it ...

The Advance CurveAll engines require an ignition curve based both on the requirements of engine rpm and cylinder filling (volumetric efficiency). This means that at 3,000 rpm with the throttle open ...

Engine knocking, or detonation, occurs when fuel in the cylinders ignites unevenly, causing metallic pinging sounds, reduced power, and potential engine damage. Key causes include low-octane fuel, ...

Mixture formation and the ignition process in 4 cycle 4 cylinder spark ignition engines were investigated, using an optical combustion sensor that combines fiber optics with a conventional spark plug.

Car manufacturers are delving deep into their boxes of tricks to make internal combustion engines more efficient. Infiniti unveiled a variable compression ratio engine last year, and hybrid technology ...

At the heart of an internal combustion engine lies a series of cylinders, cylindrical chambers that house the fiery combustion process. These cylinders, arranged in various configurations such as ...

November 27, 2004 A white paper on a revolutionary new approach to engine design has been released at the Global Powertrain Conference (GPC) in Dearborn, Michigan, USA. Quasiturbine technology uses ...
