There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

Somewhere there's a perfect balance between peak horsepower, low-speed response, reduced emissions, and something you can afford. Variable valve timing and lift have done their part in getting us all ...

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 ...

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 jargon goes well beyond just names. Car specs are full of abbreviations that may or may not have any meaning at first glance. And sometimes we get so used to seeing those abbreviations that we may ...

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 ...

Imagine a valve control system without compromises, one that isn’t crank-driven and doesn’t play by conventional rules. Such an engine would allow infinitely variable timing on all its valves, ...

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 ...

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 ...
