A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

A mixing valve of an exhaust-gas recirculation device of an internal combustion engine of a motor vehicle includes an intake flap and an exhaust-gas flap coupled rigidly to one another via a coupling rod. During driving of the exhaust-gas flap, the intake flap is first pivoted in the opposite direction via the coupling rod. The exhaust-gas flap and intake flap are pivoted in the same direction only above a provided pivoting angle.

An internal combustion engine includes an engine block including a cylinder having a cylinder axis, a piston positioned within the cylinder and configured to reciprocate along the cylinder axis, a crankshaft configured to rotate about a crankshaft axis, an air-fuel mixing device configured to provide an air-fuel mixture to the cylinder, a cyclonic air filter positioned entirely below the air-fuel mixing device, and a duct coupling the cyclonic air filter to the air-fuel mixing device and configured to provide air filtered by the cyclonic air filter to the air-fuel mixing device.

Described is a jet fuel filter assembly. The jet fuel filter assembly includes an elongated filter cartridge and a filter element formed to fit within the bottom of the filter cartridge. The filter element consists of a hollow tube member and flow vanes extending from an interior wall of the hollow tube member toward a center of the hollow tube member. The flow vanes redirect jet fuel entering the filter cartridge in a helical path, thereby preventing premature rupturing of the filter cartridge due to jet fuel surges.

Embodiments of a combustion section including a fuel injector assembly are provided. The combustion section includes the fuel injector assembly coupled to an outer casing and a liner assembly. The fuel injector assembly includes a body defining a first inlet opening and a second inlet opening spaced apart from one another along a first direction. The body further defines a fuel-oxidizer mixing passage therewithin extended along a second direction at least partially orthogonal to the first direction. The first inlet opening and the second inlet opening are each in fluid communication with the fuel-oxidizer mixing passage. The body defines an outlet opening at the fuel-oxidizer mixing passage at a distal end relative to the first inlet opening and the second inlet opening. The first inlet opening and the second inlet opening are each configured to admit a flow of oxidizer to the fuel-oxidizer mixing passage. The fuel-oxidizer mixing passage is configured to provide a flow of fuel-oxidizer mixture to a combustion chamber via the outlet opening.
