摘要： Heat recovery systems are useful, for example, in vehicles that generate large amounts of heat energy during operation. The heat energy is used to drive a turbine that produces useful work. In order to fully utilize the great majority of the heat energy produced, the engine exhaust is used to convert a fluid to a gas and superheat the gas to a preselected temperature at a preselected pressure. If the fluid entering the heat exchanger in the exhaust system is to cool, soot collects on the heat exchanger thus greatly reducing system efficiency. Also various oxides precipitate out of the exhaust and chemical attack the elements in the exhaust system. The present heat recovery system utilizes the heat energy from the oil cooling system to preheat all of the fluid before it reaches the exhaust system. Furthermore, the heat energy from the jacket water of the engine is used to convert a portion of the preheated fluid to a gas. The system converts the remaining portion of fluid to a gas and superheats the gas to a higher preselected temperature. A first stage of a dual pressure turbine receives the superheated gas and directs the gas at a supersonic velocity against the blades of the rotor. The gas exiting the first stage and the superheated gas at a lower preselected temperature is controllably and substantially separately directed to a second stage at substantially the same velocity.

摘要： In order to accurately determine a life of a turbocharger, the specific use, herein referred to as a “duty cycle” of the turbocharger, should be monitored. However, in order to directly monitor the duty cycle of the turbocharger, there are additional costs of assembly and installation of a turbocharger rotational speed sensor. The present invention determines a life of a turbocharger by indirectly monitoring the duty cycle of the turbocharger through sensors that generally serve a pre-existing purpose within a vehicle or machine. A compressor inlet pressure sensor and compressor outlet pressure sensor are in communication with an electronic control module that includes a life determining algorithm. The life determining algorithm determines the life of the turbocharger based on a relationship between a sensed compressor inlet pressure and a sensed compressor outlet pressure. By monitoring the relationship between the sensed compressor inlet pressure and the sensed compressor outlet temperature, the fatigue and the creep of at least one component of the turbocharger is monitored.
摘要翻译：为了准确地确定涡轮增压器的使用寿命，应该监视涡轮增压器的具体用途（这里称为“占空比”）。然而，为了直接监视涡轮增压器的占空比，涡轮增压器转速传感器的组装和安装有额外的成本。本发明通过间接地监测涡轮增压器的占空比来确定涡轮增压器的寿命，该传感器通常用于车辆或机器内预先存在的目的。压缩机入口压力传感器和压缩机出口压力传感器与包括寿命确定算法的电子控制模块通信。寿命确定算法基于感测的压缩机入口压力和感测的压缩机出口压力之间的关系来确定涡轮增压器的寿命。通过监测感测的压缩机入口压力和感测的压缩机出口温度之间的关系，监测涡轮增压器的至少一个部件的疲劳和蠕变。

摘要： A unitary system for removing particulates from the exhaust gas of an internal combustion engine includes a main flow passage and a by-pass flow passage for conducting the exhaust gas from an inlet portion to an outlet portion of a housing which contains the system. A valve for selectively directing the exhaust gas through one of the passages is provided, with a particulate trap mounted in the main flow passage for trapping particulates within the exhaust gas when the exhaust gas is directed therethrough. A regeneration system is positioned intermediate the valve and the particulate trap with an oxidation catalyst being positioned downstream of the particulate trap and in both the main flow passage and the by-pass flow passage. Further, a control system is provided for selectively activating and deactivating the regeneration system in response to predetermined operating conditions of the unitary system.

摘要： Exhaust gases from diesel and some other engines vary in temperature from about 100.degree. C. to about 800.degree. C. Exhaust is passed along with ammonia to a first reactor wherein the ammonia reduces nitric oxide at temperatures down to a threshold temperature between about 220.degree. C. to about 280.degree. C. Above this threshold temperature the effluent from the reactor is passed to the exhaust. When the first reactor effluent is at a temperature below the threshold temperature, it is passed through a second reactor after intermediate cooling, wherein it contacts an ammonium halide on activated charcoal catalyst at a temperature of 100.degree. C. to 170.degree. C., which catalyst catalizes the low temperature reduction of nitric oxide with ammonia.
