In order to set a stage for what follows, let's first revisit some of the fundamentals involved in how valve timing relates to power output. And to further clarify how "power" is defined in the ...

Once upon a time, picking a cam for a given engine combo was all about compromise: improve top-end power at the expense of low-end torque, run well at wide-open throttle but sacrifice idle stability ...

The first production car engine with variable valve timing (VVT) came from Alfa Romeo in 1980. It was installed in the fuel-injected Alfa Romeo Spider. Before this, a few experimental systems existed, ...

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 ...

In addition to the core elements listed below, the new engines announced today incorporate other new and proprietary technologies. Mitsubishi Innovative Valve timing Electronic Control (MIVEC)Aluminum ...

Engines are complex bits of machinery. At their core level, yes, it's easy to understand what is happening. Air and fuel enter the engine where they are ignited and combustion occurs resulting in ...

Among Honda's many technologies, none ranks as synonymous with the brand as VTEC. The company's unique, dynamically adjustable valvetrain is, in large part, what helped make '90s-era Civics and ...

The problem is as old as the internal combustion engine itself: Static valve timing is always a compromise. Figures that produce good power at lower engine speeds aren't ideal for higher-rpm operation ...

Not too long ago, we reported on the news that Indian Motorcycle had a new liquid-cooled engine in the works. That engine was suspected to be the same one that appeared under the Victory name a few ...
