Abstract
Systems are provided for a crankcase ventilation system. In one example, a crankcase ventilation (CCV) system for an engine configured to transmit crankcase gases into a clean side air duct, the clean side air duct comprising a sensor and a crankcase ventilation spigot, wherein the crankcase ventilation spigot is configured to be disposed downstream of the sensor, the crankcase ventilation spigot having an outlet configured to direct crankcase gases emerging from the crankcase ventilation spigot away from the sensor.
Claims20
A system comprising a crankcase ventilation (CCV) system for an engine configured to transmit crankcase gases into an interior volume of an air duct, the system, comprising:
- a sensor arranged in the interior volume upstream of a crankcase ventilation spigot relative to a direction of intake air flow;
- wherein
- the crankcase ventilation spigot comprises an outlet configured to direct crankcase gases emerging from the crankcase ventilation spigot away from the sensor, wherein a diameter of a cross-section of the outlet is reduced relative to other portions of the crankcase ventilation spigot.
A engine system, comprising:
- an intake passage comprising a mass air flow sensor and a turbocharger;
- and
- a spigot arranged between the mass air flow sensor and the turbocharger, wherein the spigot is configured to direct crankcase gases directly into an interior volume of the intake passage in a direction towards the turbocharger.
A system, comprising:
- a crankcase fluidly coupled to an intake passage via a spigot, wherein the spigot comprises a first portion extending from the crankcase into an interior volume of the intake passage and a second portion extending from the first portion within the interior volume, wherein one of the first portion or the second portion comprises a tapered cross-sectional flow-through area reducing in a direction of crankcase gas flow.
