Abstract: A supplemental fuel system includes a fuel mixer. The fuel mixer includes a nozzle and a stem. The nozzle is configured to be positioned within a conduit of an air supply system for a compression-ignition engine. The nozzle has a body defining a first inlet positioned at a first nozzle end thereof, an outlet positioned at a second nozzle end thereof, a second inlet positioned between the first nozzle end and the second nozzle end, and a nozzle passage extending from the first nozzle end to the second nozzle end that is configured to receive air flowing through the conduit. The stem has a first stem end interfacing with the second inlet. The stem is configured to extend through a wall of the conduit such that a second stem end is positioned outside of the conduit.

Abstract: A supplemental fuel system for a machine having a compression-ignition engine includes an air intake tube. The air intake tube has a first end configured to interface with an air cleaner of an air supply system that provides air to the compression-ignition engine, a second end configured to interface with a compressor of a turbocharger of the air supply system, and a sidewall extending between the first end and the second end. The sidewall includes a fuel interface configured to facilitate providing a supplemental fuel into the air intake tube to mix with the air upstream of the compressor of the turbocharger.

Abstract: A supplemental fuel system includes a supplemental fuel tank, an electronic valve, a temperature sensor, and a controller. The supplemental fuel tank is configured to store a supplemental fuel configured to supplement a primary fuel used by an engine. The electronic valve is configured to be positioned between the supplemental fuel tank and an air supply system for the engine. The temperature sensor is configured to acquire temperature data regarding a temperature of the engine. The controller is configured to control the electronic valve such that the electronic valve is (i) closed to prevent the supplemental fuel from being provided to the air supply system in response to the temperature being less than a temperature threshold and (ii) open or openable to permit the supplemental fuel to be provided to the air supply system in response to the temperature being greater than the temperature threshold.

Abstract: A supplemental fuel system includes a supplemental fuel tank, a first pressure regulator, a second pressure regulator, and a nozzle. The supplemental fuel tank is configured to store a supplemental fuel at a first pressure. The first pressure regulator is configured to reduce the first pressure of the supplemental fuel received from the supplemental fuel tank to a second pressure. The second pressure regulator is configured to reduce the second pressure of the supplemental fuel received from the first pressure regulator to a third pressure. The nozzle is configured to be positioned (i) downstream of the second pressure regulator and (ii) within a conduit of an air supply system for the compression-ignition engine. The nozzle is configured to receive a flow of the supplemental fuel and provide the supplemental fuel to air flowing though the conduit.

Abstract: A supplemental fuel system includes a fuel mixer having a nozzle and a stem. The nozzle is configured to be positioned within a conduit of an air supply system for an engine. The nozzle has a body defining a first inlet, an outlet, a passage extending from the first inlet to the outlet, and a second inlet positioned between the first inlet and the outlet. The body has a first cross-sectional dimension that is configured to be less than a second cross-sectional dimension of the conduit such that (i) a first portion of air flowing through the conduit flows through the passage and (ii) a second portion of the air flowing through the conduit flows around the nozzle. The stem has a first end that interfaces with the second inlet. The stem is configured to extend through a wall of the conduit.
