Engineers at Waterloo University are improving on the traditional engine by introducing variable hydraulic valves in place of cam-based and camless systems. While the engineering community continues ...

The combination of physical models, including a combustion model of an advanced engine control system, was proposed to obtain sophisticated air/fuel ratio and residual gas fraction control in lean ...

Automatic variation of internal combustion engine valve timing in response to load and speed is an effective technique for reducing emission of oxides of nitrogen and unburned hydrocarbons. The ...

August 5, 2005 Mitsubishi Motors Corporation (MMC) has developed two Mitsubishi Innovative Valve timing Electronic Control (MIVEC) aluminium cylinder block engines to power two new models slated for ...

It seems like every major automaker these days is using tricks like variable-valve timing – often in conjunction with forced induction – to eke better efficiency out of their engines while still ...

If all V engines had sported overhead cams since the beginning of automotive time, someone surely would have come up with the brilliant idea of incorporating a single camshaft deep inside the block ...

One of the interesting things about critical needs is that we tend to take them for granted once achieved. Food, clothing, and shelter have been joined by power and connectivity as survival demands in ...

Essentially, a multi-cylinder engine is a collection of individualengines operating at different combustion and mechanical efficiencies.If we can optimize the power output from each one, the overall ...

Santa Cruz, Calif. — Incentia Design Systems Inc. has added an “advanced” on-chip variation capability (OCV) to its TimeCraft static timing-analysis tool, claiming the function's variable derating ...
