    • A method for calibrating an engine is provided. The engine includes a cylinder for combustion of a fuel. The method includes setting combustion parameters of the engine, detecting a combustion noise during combustion proximate to the cylinder, detecting an engine sound radiated from the engine during combustion, adjusting the combustion parameters and repeating the steps of detecting a combustion noise and detecting an engine sound. The method further includes generating a relationship between the combustion noises and the engine sounds, determining a combustion noise level that correlates to a predefined engine sound threshold from the relationship, adjusting a speed of the engine and a load on the engine and repeating the previous steps to determine a combustion noise level for each engine speed and engine load setting, and calibrating the engine using the combustion noise levels.

    • An EGR system compensates for differing EGR flows and/or exhaust temperatures and can maintain the cooler exit temperature above the critical temperature, thereby reducing the possibility of EGR cooler fouling. A plurality of exhaust gas recirculation cooler modules is disposed between an exhaust gas passage and an air passage. The cooler modules receive exhaust gas from the exhaust gas passage and supply the received exhaust gas to the air passage for recirculation into an intake manifold. Each of the cooler modules includes a cooler portion, a bypass portion, and a flow control device. The cooler portion and the bypass portion are arranged such that fluid flowing through the cooler portion and the bypass portion flows therethrough without flowing through the other of the cooler portion and the bypass portion. The cooler portion reduces a temperature of the fluid flowing through the cooler portion.
    • EGR系统补偿不同的EGR流量和/或排气温度,并可将冷却器出口温度保持在临界温度以上,从而降低EGR冷却器结垢的可能性。 多个废气再循环冷却器模块设置在废气通道和空气通道之间。 冷却器模块从废气通道接收废气并将接收的废气供应到空气通道以再循环到进气歧管中。 每个冷却器模块包括冷却器部分,旁路部分和流量控制装置。 冷却器部分和旁路部分布置成使得流过冷却器部分和旁路部分的流体不流过冷却器部分和旁路部分中的另一个而流过。 冷却器部分降低流过冷却器部分的流体的温度。

    • Exemplary embodiments of the present invention are directed towards an apparatus and method for control of fluid flow through a conduit of an exhaust system for an engine, particularly prior to an exhaust treatment device. In one embodiment, a fluid flow control device for receiving and guiding exhaust gas from an engine towards an exhaust gas treatment device is provided. The fluid flow control device includes a nozzle disposed within an exhaust conduit of the engine. The nozzle includes an inlet opening and an outlet opening for forming a first flow path through the nozzle. The nozzle is spaced from the exhaust conduit for forming a second flow path between the nozzle and the exhaust conduit. The fluid flow control device also includes an injector disposed adjacent the nozzle. The injector may be oriented to direct a pressurized fluid to the first or second flow path.
    • 本发明的示例性实施例涉及用于控制通过用于发动机的排气系统的导管的流体流动的装置和方法,特别是在排气处理装置之前。 在一个实施例中,提供了一种用于从发动机向排气处理装置接收和引导废气的流体流量控制装置。 流体流量控制装置包括设置在发动机的排气管道内的喷嘴。 喷嘴包括用于形成通过喷嘴的第一流动通道的入口和出口。 喷嘴与排气导管间隔开,以在喷嘴和排气管之间形成第二流路。 流体流量控制装置还包括邻近喷嘴设置的喷射器。 注射器可以被定向成将加压流体引导到第一或第二流动路径。
