Abstract: An aftertreatment device for reducing NOx, PM, HC, and CO generated by a compression-ignition engine. In this device, lean exhaust air generated in the engine is enriched using a reactor together with an oxygen sorption device according to a target deNOx efficiency value, and heat energy is recovered. The enriched exhaust gas then passes through an oxidation catalyst, where NOx is reduced with CO and HC. PM in the exhaust gas is further trapped in a DPF. To lower energy cost, an heat exchanger is used for more effectively heating the DPF during regeneration, and an exhaust gas compressor positioned upstream from the DPF is employed to control engine back pressure. When exhaust gas temperature is low, to regenerate the DPF with minimum energy consumption, an electrical heater is used to heat dosing fuel before it is mixed with exhaust gas, and a regeneration heating process is then jump-started.

Abstract: A fluid delivery apparatus for delivering fluid according to a fluid delivery rate command including a fluid tank, a pump, a buffer, in which a pressure sensor is positioned, an injector, a pump controller, a fluid delivery controller, and a diagnostic controller. When a motor driven pump is used, the diagnostic controller is able to detect issues by comparing a measured pressure change with an expected value calculated using pressure sensing values and the power applied to the motor. If an air driven pump is employed, pressure sensing values, fluid delivery rate commands, and pump operating status can be used for calculating compressed air volume in the pump and trapped air volume in the buffer, and for further triggering pressing and suction strokes of the air driven pump, diagnosing issues in the fluid delivery apparatus, detecting fluid level in the fluid tank, and refilling trapped air in the buffer.

Abstract: A fuel injection apparatus with a piston device that includes a channel and a piston in the channel. A position sensor is used to detect the piston movement inside the channel when the fuel injection apparatus is energized and de-energized, and the sensing value is used for controlling fuel injection rate in real-time and diagnosing failures in the apparatus. With an actuator installed, the piston can also be used for independently modulating fuel pressure during fuel injection. Thereby the shape of fuel injection pulses is controlled. The fuel injection apparatus has three injection states, and flexible fuel injection timing and multi-pulse injection are allowed. Furthermore, in all injection states, fuel supply has no direct contact to combustion chamber. As a result, when a malfunction sticks the apparatus open, no fuel is supplied. This feature provides a safety nature to the fuel injection apparatus.

Abstract: A standalone thermal energy recycling device in which exhaust air emitted from an internal combustion engine exchanges heat with that being heated during regeneration of after-treatment devices. By using the thermal energy recycling device, heat generated for regeneration is used to compensate energy loss during heat exchange rather than provide the overall energy needed for boosting exhaust flow temperature to target. Inside the thermal energy recycling device, heat exchanger is bypassed during normal engine operations for decreasing back pressure.
