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 ...

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 ...

The reciprocating engine has been all the rage for at least three centuries. The first widely adopted engine of this type was the steam engine with a piston translating linear motion into rotational ...

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 ...

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 ...

Reciprocating engines in sizes from a few kilowatts to several MW are used to generate electricity by utilities, hospitals, manufacturing plants and commercial buildings. For many years these engine ...

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 ...
