Fixed orifice vs variable orifice
WebSome manufacturers utilize a fixed-orifice restrictor instead of or in addition to a conventional variable-flow valve. Any oil droplets incorporated into PCV flow eventually wind up as soot particles that can foul exhaust oxygen or air/fuel sensors or degrade catalytic converter substrates. WebVariable Orifice. (To be removed) Generic hydraulic variable orifice. The Hydraulics (Isothermal) library will be removed in a future release. Use the Isothermal Liquid library instead. (since R2024a) For more information on updating your models, see Upgrading Hydraulic Models to Use Isothermal Liquid Blocks.
