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 ...
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 ...
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 ...
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, ...
