摘要： A safe, reliable SCR system for reducing NO.sub.x emissions from a lean-burn internal combustion engine utilizes urea in aqueous solution. A modular assembly is provided for mounting inside a urea reagent tank enables controlled feeding an aqueous urea solution to an injector. The assembly includes a reagent quality sensor, a reagent temperature sensor, a reagent level sensor and a pump.

摘要： An injector for delivery of a fluid into a stream of hot gas is disclosed. The injector has a valve body with an elongated chamber in fluid communication with an orifice. A valve seat surrounds the orifice. A valve plunger is disposed within the chamber, an end of the plunger being adapted to sealingly interengage the seat. The plunger is slidably movable between an open and a closed position to open and close the orifice. A fluid inlet and an outlet are disposed within the valve body to deliver fluid to an annular fluid passageway in the chamber adjacent to the valve seat. Fluid is circulated through the annular passageway to cool the valve and a portion of the fluid is expelled through the orifice when the orifice is opened. The plunger is biased into the closed position by a coil spring and movable into the open position by a solenoid actuator mounted atop the valve body. The injector is mounted on an exhaust conduit of an internal combustion engine with the orifice in fluid communication with the exhaust gases. A heat shield surrounding the orifice is interposed between the exhaust gases and the valve body, a radiant heat reflector is positioned between exposed parts of the injector and the exhaust conduit, and an atomizing hook is positioned in a spaced apart relation facing the orifice to control the dispersion characteristics of the expelled fluid.

摘要： A safe, reliable system for automatically dosing diesel truck fuel tanks with a fuel additive is provided. The additive, such as a concentrated solution containing fuel borne catalyst (FBC), is fed by positive feed means in pulsed doses while the engine is on. The frequency and amount of FBC injection is controlled as a function of the time the engine is operated and predetermined values for rate of fuel consumption and intended additive concentrations in the fuel.

摘要： A safe, reliable system for automatically dosing diesel truck fuel tanks with a fuel additive is provided. The additive, such as a concentrated solution containing fuel borne catalyst (FBC), is fed by gravity and dosing is controlled with a signal from a switch located on the ignition switch and/or the fuel tank cap and filler spout. When the ignition switch is in the on position and/or the cap is removed, a solenoid opens a valve and permits a timed or otherwise measured amount of additive to flow into the tank while the cap is off. Replacing the cap and/or turning off the ignition switch preferably stops the flow of additive, the flow rate being set to supply a predetermined amount of additive during an average refueling interval.
