A number of studies have demonstrated that the variable valve timing technology can potentially improve engine torque and power, reduce automotive emissions and fuel consumption [4, 5] .
Does VVA consume more fuel?
VVA uses the first cam between 0rpm to 7400rpm. This cam offers better low-end grunt. At 7400rpm, an actuator pushes a pin in the rocker arm to activate the second cam profile with a larger lobe. The second camshaft also opens the intake valves by an additional 2mm, letting in more air and fuel for higher combustion.
