Abstract
An air-fuel mixer includes a body having an inlet, an outlet, and an air passage therebetween. One or more fuel injectors are mounted to the body and positioned to inject fuel into the air passage with little or no space between the injector nozzles and the air passage. The fuel injectors may be inclined in an air-fuel mixer outlet direction whereby they inject fuel into the air passage with momentum in a direction of the outlet. Swirl guides are provided within the air passage. The air-fuel mixer may be installed between an intake manifold and an intercooler. The air-fuel mixer provides good mixing, low resistance to air flow, reduced fuel slip, and crisp responses to throttle up and throttle down commands.
Claims17
An air-fuel mixer, comprising:
- a body having an air inlet, an air outlet, and an air passage extending from the air inlet to the air outlet;
- a fuel injector attached to the outside of the body, wherein the fuel injector has a nozzle positioned to inject fuel into the air passage through a port in the body, the nozzle is angled toward the air outlet;
- and swirl guides projecting into the air passage, wherein the swirl guides are positioned to impart swirl to air flowing from the air inlet to the air outlet;
- wherein the fuel injector is one of two or more fuel injectors provided by and attached to the body by a fuel rail that abuts the body.

- a fuel injector attached to the outside of the body, wherein the fuel injector has a nozzle positioned to inject fuel into the air passage through a port in the body, the nozzle is angled toward the air outlet, and the nozzle is positioned to inject fuel into the air passage through a port in the body;
- swirl guides projecting into the air passage, wherein the swirl guides are positioned to impart swirl to air flowing from the air inlet to the air outlet;
- wherein the fuel injector is provided by and attached to the body by a fuel rail that abuts the body;
- and wherein the nozzle is angled away from a centerline of the air passage.
