Abstract: Apparatuses, systems and methods are disclosed for separating oil from a blow-by gas of an engine. An example includes a method that includes passing the blow-by gas to a first oil separating apparatus and a second oil separating apparatus, wherein the first oil separating apparatus and the second oil separating apparatus are physically coupled together along interfacing surfaces and in fluid communication with one another as an array, separating the blow-by gas by passing the blow-by gas through respective filters of the first oil separating apparatus and the second oil separating apparatus, removing the oil from the blow-by gas with the respective filters and recombining the blow-by gas after passing from the respective filters; passing the blow-by gas as a single flow stream from the first oil separating apparatus and the second oil separating apparatus.

Abstract: An air shutoff valve for use on an internal combustion engine includes a gate that is moveable between armed and triggered positions by springs when a release pin is retracted and allows a spring loaded retention pin to retract and release the gate, which is also spring loaded, to drop. The release pin is operated by an actuator.

Abstract: Apparatuses, systems and methods are disclosed including apparatus for separating oil from a blow-by gas of an engine. The apparatus can include an outer housing, an inner housing, a filter, one or more ports, a first cover and a second cover. The inner housing can be positioned within the outer housing and defines an inner cavity. The inner housing and the outer housing can form a jacket therebetween. The filter configured to separate the oil from the blow-by gas positioned within the inner cavity. The one or more ports can be configured for fluid communication with the jacket. The first cover can have at least a first port therein to receive the blow-by gas or allow the blow-by gas to pass from the first cover. The second cover can have a second port therein to receive the blow-by gas or allow the blow-by gas to pass from the second cover.
