Variable valve lift vs variable valve timing - VVL vs VVT
What is VVL? What is VVT? How does VVL/VVT work? What is variable valve lift? What is variable valve timing? We're going to ...
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 ...
Most modern variable valve-timing (VVT) systems use a cam phaser that rotates the position of each camshaft relative to the timing chain. Think of making a record turntable go faster or slower by ...
The bike that won the title of “world’s fastest production motorcycle” at the turn of the century could soon sport a bit of tech that will support hi-rev performance at lower emissions… but at what ...
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 ...
Every aspect of an engine is a compromise: torque for horsepower, efficiency for emissions, performance for fuel economy, compression for octane tolerance. During the evolution of the internal ...
Without variable valve timing, these intake and exhaust valves would operate in the same manner regardless of the engine’s RPM (revolutions per minute) speed or the driving environment. This isn’t ...
