摘要： A direct injection fuel injector system includes a fuel injector defining nozzle holes in an optimized cluster configuration. Each hole of a conventional multi-hole nozzle is replaced by two smaller, closely spaced holes in a two-hole-per-cluster configuration. The holes within a cluster are configured one above the other, in two horizontal planes or rows, spaced a distance apart from one another. The distance “d” between the nozzle holes in the cluster configuration, the clustered plume angle “α”, which is the angular separation between the centerlines of the nozzle holes, as well as the included spray angle “β”, are optimized through computational fluid dynamics and combustion modeling so that an optimal compromise can be found between liquid penetration, spray penetration and air entrainment, whereby to minimize soot emissions.

摘要： 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.

摘要： 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.

摘要： 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.
