Abstract
Various systems and methods are provided for reducing an amount of oil reaching a crankcase overpressure sensor. In one example, a system may include a cast wall protruding perpendicularly from an internal wall of crankcase, the cast wall at least partially surrounding a sensor port for a crankcase overpressure (COP) sensor, the sensor port fluidically coupled to the COP sensor via an internal passage; and a cover plate fixedly coupled to the cast wall, the cover plate parallel to the internal wall. In this way, oil may be blocked from reaching the COP sensor, while air may flow through the internal passage to the COP sensor.
Claims14
A system, comprising:
- a cast wall protruding perpendicularly from an internal wall of a crankcase of an engine, the cast wall at least partially surrounding a sensor port for a crankcase overpressure (COP) sensor, the sensor port fluidically coupled to the COP sensor via an internal passage;
- and a cover plate fixedly coupled to the cast wall via at least two fasteners, at least a portion of the cover plate parallel to the internal wall, extending from the cast wall to an edge of the internal wall, each of the fasteners extending perpendicular to the internal wall.
A system, comprising:
- a cast wall protruding perpendicularly from an internal wall of a crankcase of an engine, the cast wall at least partially surrounding a sensor port for a crankcase overpressure (COP) sensor, the sensor port fluidically coupled to the COP sensor via an internal passage;
- and
- a cover plate fixedly coupled to the cast wall, at least a portion of the cover plate parallel to the internal wall, wherein the cast wall includes a first linear section, a second linear section, and a third linear section, the first linear section perpendicular to the second linear section, and an angle between the second linear section and the third linear section less than 180 degrees, wherein the cover plate extends from the cast wall to an edge of the internal wall, and wherein the third linear section and the edge of the internal wall are separated by a gap.
A method, comprising:
- monitoring a crankcase pressure in a crankcase of an engine based on a signal from a crankcase overpressure (COP) sensor, the COP sensor coupled to an integrated front end housing of the crankcase, and a sensor port of the COP sensor at least partially surrounded by a cast wall and a cover plate, wherein the cast wall is vertically centered with an idler gear and a crank gear, and the cover plate is on an opposite side of the idler gear from the crank gear when viewed from a front of the engine.
