A power system for a work vehicle includes an alcohol tank configured to store alcohol; a catalytic converter fluidly coupled to receive alcohol from the alcohol tank and configured to convert the alcohol into ether; and an engine including one or more piston-cylinder sets configured to selectively receive the alcohol stored in the alcohol tank and the ether converted by the catalytic converter and to combust the alcohol and the ether with air to produce mechanical power and exhaust gas.

A system is provided. The system includes a controller communicatively coupled to an industrial combustion engine and an exhaust gas recirculation (EGR) system, wherein the EGR system is configured to route exhaust gas generated by the industrial combustion engine from at least one exhaust system to at least one intake system, the EGR system includes multiple EGR circuits, each EGR circuit of the multiple EGR circuits includes an EGR cooler unit including at least two of a high temperature non-condensing cooler, a low temperature condensing cooler, an adiabatic gas/liquid separator, and a reheater. The controller includes a processor and a non-transitory memory encoding one or more processor-executable routines, wherein the one or more routines, when executed by the processor, cause the controller to control operations of both the industrial combustion engine and the EGR system.

The present invention provides an EGR cleaning station and method of use for efficiently cleaning EGR from soot and debris. The gas recirculation cleaning station is primarily comprised of: a cleaning tank; a water tank; a heating system; a pump; an inlet hose; an outlet hose; and, exterior housing. The EGR cleaning station isolates the EGR while mounted onto the internal combustion engine. The cleaning of the EGR occurs without the need to remove the EGR from the internal combustion engine.

An embodiment apparatus for reducing fouling of an exhaust gas recirculation (EGR) cooler includes an exhaust gas transfer part configured to connect a diesel oxidation catalyst (DOC) of an exhaust gas post-treatment system extending from an engine through an exhaust line to an EGR cooler installed in an EGR line and configured to recirculate exhaust gas discharged from an exhaust manifold to an intake manifold, a valve installed in the exhaust gas transfer part, and a controller configured to selectively open the valve as the exhaust gas post-treatment system enters a predetermined diesel particulate filter (DPF) regeneration condition and allow exhaust gas discharged from the DOC to be supplied to the EGR cooler through the exhaust gas transfer part.

A fuel reformer for producing a steam reforming reaction between fuel and water on a reforming catalyst includes a fuel injection part that injects and supplies fuel into the reforming catalyst, and an injection control part that controls an injection amount of fuel by the fuel injection part. The injection control part controls the injection amount in order that a temperature of the reforming catalyst is not lower than a preset given temperature. The fuel reformer further includes a temperature obtaining part that measures or estimates the temperature of the reforming catalyst, and a target value calculation part that calculates a target value of the injection amount, such that the temperature of the reforming catalyst after fuel is injected by the fuel injection part is equal to or higher than the given temperature. The fuel injection part is controlled such that the injection amount coincides with the target value.

A method of operating an dedicated exhaust gas recirculation engine including a water gas shift catalyst by supplying ambient air and fuel to a dedicated cylinder at a first fuel to air equivalence ratio in the range of greater than 1.0 to 1.6 for a first number of engine cycles and, for a second number of engine cycles, supplying ambient air and fuel to the dedicated cylinder at a second fuel to air equivalence ratio in the range of 0.7 to less than 1.0. During the second number of cycles, spark timing of the dedicated cylinder is adjusted and a time delay when exhaust recirculated from the dedicated cylinder will be inducted into the cylinders is determined. At the end of the time delay, a second spark timing of the main cylinder is adjusted and the amount of fuel supplied to the main cylinders is increased.
