摘要： A valve overlap period is increased as a desired torque of an engine increases by advancing an opening timing of an intake valve at a rate greater than that of retarding a closing timing of an exhaust valve in a low engine-torque area in which the desired torque of the internal combustion engine is relatively low (step S16). The valve overlap period is increased as the desired torque of the engine increases by retarding the closing timing of the exhaust valve at a rate greater than that of advancing the opening timing of the intake valve in a high engine-torque area in which the desired torque of the internal combustion engine is relatively high (step S17). Accordingly, the drivability can be improved by obtaining the proper torque and the smooth torque curve in the wide driving area.
摘要翻译：随着发动机的期望扭矩的增加，阀重叠周期增加，因为在低发动机 - 转矩区域中以大于延迟排气门的关闭正时的速率推进进气门的打开正时，其中期望扭矩的内燃机相对较低（步骤S16）。随着发动机的期望扭矩的增加，阀重叠周期增加，因为在高发动机扭矩区域中，通过将排气门的关闭正时以比进气门的打开正时大的速率延迟，的内燃机相对较高（步骤S17）。因此，可以通过在宽行驶区域中获得适当的扭矩和平滑的扭矩曲线来提高驾驶性能。

摘要： An intake manifold for a multi cylinder internal combustion engine has a common upstream passage and individual downstream passages, leading individually to cylinders of the engine, respectively. These individual downstream passages are connected between a downstream end of the common upstream passage and the cylinders. Upstream end portions of the individual downstream passages are symmetrically located around a fuel injector, disposed downstream relative to the common upstream passage, and are joined together. At a center of the symmetrically joined upstream end portions of the individual downstream passages, fuel passages are provided to open independently into the upstream end portions so as to introduce fuel from the fuel injector into the individual downstream passages.

The intake system includes an intake manifold having a plurality of discrete intake passages connected to the plurality of cylinders, respectively, and two intake pipes, each intake pipe being arranged in such a way as to descend substantially vertically downwardly from a communicating portion where the intake pipe communicates with each of two groups of the intake passages, turns to extend horizontally in one longitudinal direction of the engine body and then turns back to extend in the opposite longitudinal direction of the engine body surrounding the discrete intake passages. The two groups of the discrete intake passages are connected to two groups of the cylinders which in each and the same group are not intended to be fired one after another.

摘要： Three or more independent passages are coupled to respective cylinders which are different from each other, and a collective portion where the independent passages collect is provided. An exhaust turbocharger is arranged downstream of the collective portion. Rotary throttle valves are arranged respectively in the independent passages upstream of the collective portion. At least two of the throttle valves are supported by a common rotary axis. The independent passages with the throttle valves supported by the common rotary axis are coupled to cylinders which have exhaust strokes which are not adjacent to each other. Accordingly, the exhaust gas can be supplied to the exhaust turbocharger efficiently.

摘要： There is provided a method of controlling an engine system comprising an internal combustion engine, a supercharging system having at least one supercharger to boost intake air to the internal combustion engine, a turbine, and a motor. The turbine receives an exhaust gas flow through flow restriction and is capable of at least partly driving the supercharging system. The motor is capable of at least partly driving the supercharging system. The method comprises reducing the flow restriction and increasing power to drive the motor as a desired intake airflow of the engine increases. By reducing the flow restriction, such as increasing nozzle opening of a variable geometry turbine (VGT), as desired intake airflow of the engine increases, such as when the engine speed increases, an excessively high pressure in the exhaust passage may be prevented. Therefore, the residual gas in the combustion chamber may be decreased so that the knocking may be prevented without retarding the ignition timing or enriching the air-fuel ratio while more air is charged into the engine. At the same time, by increasing the power to drive the motor, such as increasing electricity supplied to an electric motor to drive a compressor, desired amount of the intake air may be charged into the engine even when the flow restriction is decreased and the turbine efficiency may be decreased accordingly. Consequently, the engine can output more torque without degrading the engine fuel economy.
摘要翻译：提供了一种控制发动机系统的方法，该发动机系统包括内燃机，具有至少一个增压器的增压系统，以增加内燃机，涡轮机和电动机的进气。涡轮机通过流量限制接收废气流，并且能够至少部分地驱动增压系统。该电机能够至少部分驱动增压系统。该方法包括当发动机的期望进气气流增加时减少流量限制和增加驱动马达的功率。通过减少流量限制，例如增加可变几何涡轮机（VGT）的喷嘴开口，如期望的发动机进气量增加，例如当发动机转速增加时，可以防止排气通道中的过高的压力。因此，可以减少燃烧室中的残留气体，从而可以在不延迟点火正时的情况下防止爆震，或者在将更多的空气充入发动机的同时增加空燃比。同时，通过增加驱动电动机的功率，例如增加供应给电动机的电力来驱动压缩机，即使当流量限制减小时，也可以将所需量的进气充入发动机，并且涡轮机效率可能相应地降低。因此，发动机可以输出更多的扭矩，而不降低发动机的燃油经济性。
