摘要： The combination of an intake air supply system with an internal combustion engine (10) having a charge air cooler, a cylinder charging air intake and an exhaust discharge is provided. The intake air supply system includes a Roots-type positive displacement blower (37) having inlet (38) and outlet (40) means and an exhaust gas driven turbo-compressor (41) connected in series with the blower (37). The intake air supply system further includes a bypass passage (58) connecting the blower inlet (38) and outlet (40) and a valve (54) in the bypass passage (58) to control the flow of fluid through the bypass (58). The valve (54) is operative to open and close the bypass passage (58) in response to engine operating parameters and to modulate the flow area of the passage (58) in response to the same engine operating parameters so as to infinitely vary the flow area between the open and closed positions of the valve (54). The valve (54) is modulated to operatively maintain the bypass passage (58) at least partially open at engine idle, whereby the valve means (54) permits bypass flow to recirculate air flow from the blower outlet (40) to the inlet (38) to reduce or limit the engine power absorbed by the blower (37) or to conduct additional air flow around the blower (37) directly from the turbo-compressor (41) to the engine intake to avoid the restriction of the blower (37) to increased charging air flow. A single valve means thus provides a dual function capability.
摘要翻译：提供了进气供应系统与具有增压空气冷却器，气缸增压空气进气和排气排气的内燃机（10）的组合。进气供应系统包括具有入口（38）和出口（40）装置以及与鼓风机（37）串联连接的排气驱动涡轮压缩机（41）的罗茨式容积式鼓风机（37）。进气供应系统还包括在旁路通道（58）中连接鼓风机入口（38）和出口（40）和阀门（54）以控制通过旁路（58）的流体流动的旁路通道（58）。响应于发动机运行参数，阀门（54）可操作以打开和关闭旁路通道（58），并且响应于相同的发动机运行参数调节通道（58）的流通面积，从而无限地改变流量阀（54）的打开和关闭位置之间的区域。阀（54）被调节成在发动机怠速时可操作地维持旁路通道（58）至少部分打开，由此阀装置（54）允许旁路流动以使空气从吹出口（40）再循环到入口（38 ）以减小或限制由鼓风机（37）吸收的发动机功率，或者将直接从涡轮压缩机（41）到鼓风机（37）周围的附加气流引导到发动机进气口以避免鼓风机（37）的限制，以增加充气空气流量。单阀装置因此提供双重功能。

摘要： A method for controlling an engine of a system having an air-charger system connected to the engine includes sensing air-charger system temperature; comparing the air-charger system temperature to a temperature threshold; and adjusting an engine control parameter when the air-charger system temperature exceeds the temperature threshold. A system for controlling engine operation is also provided.

摘要： An engine controller capable of operating in both a torque governing mode and a speed governing mode simultaneously, and a method of operation whereby speed governing may be enabled and disabled while simultaneously providing a valid speed request signal to the controller is disclosed. A speed governor signal having an enabled state and a disabled state is generated external to the controller and monitored by the speed governor. A speed request signal is simultaneously monitored by the speed governor. The speed governor is operative to control the speed of the engine proportional to the speed request signal while the speed governor signal is in the enabled state. The speed governor is disabled by setting the speed governor signal into the disabled state. A torque governor may also be operational within the controller. The torque governor monitors a torque request signal which it uses to control a torque generated by the engine.
