While the engineering community continues to explore the benefits of electric and hybrid vehicles—i.e., the environmental and renewable energy factors—the automotive market is still dependent on ...

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 ...

Ducati has announced it will introduce new engine technology that will boost power and torque, improve fuel economy, reduce emissions and won’t affect servicing intervals. Ducati Testastretta engine ...

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 ...

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 ...

SMP grows its engine sensor lineup with new coverage across key categories, supporting millions of GM, Ford, Toyota and Lexus ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...
