The cylinder calculations were carried out for complete open period, from the exhaust valve open to the
intake valve close (EVO to IVC).
Later, an intense tumble motion arises, due to the high
intake valve lift and to the piston position far from the cylinder head.
The
intake valve of a high-mileage car using Caltex with Techron fuel.
These polymerized substances are assumed to be linked to high temperature seen by the
intake valve even if it is difficult to estimate the valve heat distribution.
The
intake valve closing at low speeds is not of great importance; thus it is a low setting, but as the speed gets higher we need more time for the valve closing to achieve optimal power.
At this point, the outflow valve is close and the
intake valve is open.
The exhaust valve of cylinder number 1 and
intake valve of cylinder number 2 were simulated using this method.
This paper focuses on the influences on the performance of the CAE by the variable
intake valve lift and duration.
'
Intake Valve Lift Control works so seamlessly drivers aren't likely to notice it at all,' said Mike Anderson, General Motors' global chief engineer for Ecotec engines.
This is due to a single mechanism that mechanically couples
intake valve lift, opening duration and timing, allowing these three parameters to be varied simultaneously and continuously.
The plane abandoned one takeoff attempt because of a mechanical problem with an air
intake valve near the cockpit.
Olefins are responsible for the gum forming tendencies, the copious
intake valve deposits (cars), short shelf life and the bad smell of autogas.
