Abstract
Various methods and systems are provided for separating particles within a gas flow traveling through a gas flow passage of an engine. In one embodiment, a particle separator includes a plurality of vanes positioned across a gas flow passage through which gas flow passes, the plurality of vanes angled with respect to a flow direction of the gas flow, and a particle trap for collecting separated particles, the particle trap disposed in the gas flow passage.
Claims20
A particle separator, comprising:
- a gas flow passage comprising a wall and an interior defined by the wall for passage of a gas flow;
- a plurality of vanes attached to the gas flow passage and positioned across the interior of the gas flow passage, the plurality of vanes angled with respect to a central axis of the interior;
- and
- a particle trap for collecting separated particles, the particle trap attached to the gas flow passage.
1 more element
A system, comprising:
- a flow passage coupled to an engine for passage of a gas flow comprising at least some exhaust gas;
- and
- a particle separator positioned in the flow passage, the particle separator including a plurality of angled vanes across the flow passage and a particle trap positioned at a bottom of the flow passage for trapping separated particles.
A method, comprising:
- collecting particles from a gas using a particle separating element, the gas flowing through a gas flow passage and containing at least some exhaust gas, wherein the particles are collected while allowing the gas to flow downstream to an intake manifold of an engine, and wherein the particle separating element comprises at least one of an inertial particle separating element configured to block the particles which subsequently disengage from the gas and collect at a bottom of the gas flow passage, or a vortex particle separating element configured to produce a rotating flow on the gas as it passes through the vortex particle separating element.
