We are therefore reduced to trial and error with success or failure according to these parameters in question. Still, the main interest of "VSLAs" is to reduce intake turbulence especially by causing a swirl that envelops the valves, instead of colliding with them and therefore increasing the turbulence.tilt to the left (coriolis swirl cyclone-northern hemisphere)
hello, the motors act as air aspirators, their movements (in revolutions per minute) inevitably cause air in the intake chamber: there are therefore fuels and air and possible oxidizers that the air carries, delivered to the only tubes which channel them, and the engines work, however, thanks to the cyclones aerodynamic air, (turning to the right or to the left) these flows follow their forced and induced rotations, the engines are please, they do not give us their opinion, also engineers engineers, users who know perfectly (or very well) the behavior of their vehicles, give us their valuable advice, after several routes, urban, expressways, highways, mountains. ..as soon as modifications were made, and this is confirmed by their consumptions (no aperitifs) but the 100 km between each full score ...
it is true that the number of valves also influences the speed of admissions, and their sealing also ... the elasticity of these combined systems also pushes me to continue to search, and to produce various models of cyclones ... hoping that it still helps, and still our small ones or big fuel savings ...
