摘要： A valve shaft scraping and filtering device for use in an engine valve includes a woven mesh annulus disposed within a valve assembly and surrounding the valve shaft such that the annulus gently scrapes the valve shaft as the valve shaft reciprocates within the valve assembly without interfering with shaft actuation. The annulus may be made with a high density weave and utilized as a filter or particulate seal to trap loose particulates which may be present within the valve.

摘要： A fluid feed duct, which may be used for feeding a stream of recirculated exhaust gas into a stream of intake air for an internal combustion engine. The feed duct includes a hollow structure (10) into which a feed connection (12) is introduced via a joint structure (34). A ceramic pipe (16) is used to prevent heat from the exhaust gas stream from being conducted to mounts in the hollow structure (10) which represents the intake duct of the engine. Consequently, the intake duct can be manufactured of a thermoplastic synthetic resin material, since the risk of thermal overstressing is avoided. The feed connection also has a deflecting segment (19) which is provided in its sides with outlet openings (20). This enables the exhaust gas to be introduced in the direction of flow of the intake air, so that optimal mixing is assured and the hot exhaust gas stream is prevented from passing directly to the wall of the thermoplastic intake duct, thereby preventing the intake duct from being melted.

摘要： For reduction of toxic components in exhaust gases of internal combustion engines, particularly of nitrogen oxides in motor vehicles, a portion of the exhaust gases, essentially operating as inert gases, are recirculated into the combustion chamber of the engine for the purpose of reducing the peak combustion temperature. In the air intake region the engine is fed an adjustable mixture of partially recirculated exhaust gas and air, wherein the mass of in-flowing air and the mass of exhaust gas recirculated from the engine following its cleaning and cooling are fed respectively to its own flow rate sensor. From the determined mass flow amounts of in-flowing air and recirculated exhaust gas, an actual value signal is formed and compared with a target value signal dependent upon the respective performance specification. A regulation deviation of the actual value signal leads to an adjustment signal, which intervenes into the exhaust gas recirculation for the purpose of adjusting the amount recirculated.

摘要： A system is disclosed for estimating the mass flow of recirculated exhaust gas (EGR) from an exhaust manifold to an intake manifold of an internal combustion engine via an EGR conduit disposed therebetween and a fraction of EGR attributable to a mass of charge flow entering the intake manifold. An engine controller is responsive to current values of various combinations of the engine exhaust temperature (ETE), intake manifold pressure (IMP), differential pressure (nullP) across an EGR valve, and EGR valve position (EGRP) to determine an estimate of EGR mass flow. The controller is further operable to estimate EGR fraction as a function of the estimated EGR mass flow value, mass flow of charge entering the intake manifold, and engine speed.

摘要： A malfunction-detecting-device for an EGR stepping motor is provided wherein a circuit structure is furthermore simple and also more detailed malfunction information can be obtained by detecting the malfunction of the stepping motor during initialization drive of the stepping motor when an engine is just started. In order to determine that excitation coils of the EGR stepping motor have wire breaks, a driving-signal monitoring circuit is provide for monitoring a voltage surge as a monitoring signal generated by turning off a switching element for driving each of the excitation coils so as to cause self induction in the excitation coil. Malfunction detecting means of the EGR stepping motor is also provided for counting the number of monitoring inputs to the driving-signal monitoring circuit during initialization driving of the EGR stepping motor so as to determine the presence of wire breaks in the excitation coils when the number counted is less than the number of times the coils are driven.

摘要： A target homogeneous mode throttle opening TA1 that is suitable for homogeneous stoichiometric combustion without EGR is computed regardless of the current combustion mode. During homogeneous stoichiometric combustion without EGR, the opening of a throttle valve is controlled based on the target opening TA1. During homogeneous stoichiometric combustion with EGR, an opening adjustment value TAo is added to the target opening TA1 and the resultant is set as a target EGR throttle opening TA2. The opening of the throttle valve is controlled based on the target opening TA2. During stratified lean combustion, the fuel injection amount is controlled based on a hypothetical throttle opening TA1, which corresponds to the target opening TA1. In either combustion mode, the engine torque is adjusted based on a common control value, which is the target opening TA1. Therefore, the engine torque is not abruptly changed when the combustion mode is switched.
摘要翻译：无论当前的燃烧模式如何，都可以计算适合于无EGR的均匀化学计量燃烧的目标均匀模式节气门开度TA1。在没有EGR的均匀化学计量燃烧期间，基于目标开度TA1控制节流阀的开度。在与EGR的均匀化学计量燃烧期间，将开度调节值TAo加到目标开度TA1，并将结果设定为目标EGR节气门开度TA2。基于目标开度TA2控制节流阀的开度。在分层稀燃燃烧期间，基于与目标开度TA1相对应的假想节气门开度TA1来控制燃料喷射量。在任一燃烧模式中，基于作为目标开度TA1的公共控制值来调整发动机转矩。因此，当切换燃烧模式时，发动机扭矩不会突然改变。
