摘要： An integrated thermal and exhaust management unit for a vehicle comprises a housing defining a chamber and having an inlet through which engine exhaust gas flows. A fuel-fired heater is adjacent to the housing and is operable to heat the engine exhaust gas flowing through the chamber. A catalytic converter is adjacent to and in downstream flow communication with the chamber for catalyzing the engine exhaust gas flowing therethrough. An exhaust gas heat recovery unit is radially adjacent to and in downstream flow communication with the catalytic converter for exchanging exhaust gas heat to liquid heat for transferring to heat-requiring areas of the vehicle. A controller controls the operation of the management unit whereby the fuel-fired heater is powered if the catalyst temperature is less than a catalyst light-off temperature for efficient treatment of vehicle emissions. The exhaust gas heat recovery unit is only powered if the catalyst temperature is at or above the light-off temperature and there are heat-requiring areas in the vehicle.
摘要翻译：用于车辆的集成热和排气管理单元包括限定腔室并具有引擎排气流过的入口的壳体。燃料加热器邻近壳体并且可操作以加热流过腔室的发动机废气。催化转化器邻近并与下游流动连通，用于催化从其流过的发动机废气。废气热回收单元与催化转化器径向相邻并且与下游流动连通，用于将废气热量交换到液体热量以转移到车辆的需热区域。如果催化剂温度低于用于有效地处理车辆排放物的催化剂熄灭温度，则控制器控制管理单元的操作，由此燃料加热器被供电。如果催化剂温度等于或高于起燃温度并且车辆中存在热需要区域，则废气热回收单元仅供电。

摘要： A power control system for an electric motor driven cooling fan that directs air over the radiator and air conditioning condenser of a motor vehicle. The system includes a pulse width modulated voltage control device for controlling the voltage applied to the cooling fan motor from the vehicle engine driven generator. The voltage applied to the cooling fan motor can be controlled in response to engine coolant temperature, vehicle road speed, engine speed and the "on"/"off" state of the vehicle air conditioning system. A digital system that determines voltage pulse width in accordance with the above-mentioned variables is disclosed.
摘要翻译：一种电动机驱动冷却风扇的动力控制系统，其将空气引导到机动车辆的散热器和空调冷凝器。该系统包括用于控制从车辆发动机驱动的发电机施加到冷却风扇电动机的电压的脉宽调制电压控制装置。可以根据发动机冷却液温度，车辆道路速度，发动机转速以及车辆空调系统的“开/关”状态来控制施加到冷却风扇电动机的电压。公开了根据上述变量确定电压脉冲宽度的数字系统。
