摘要： A control system that determines a mass air flow through a throttle of an internal combustion engine (ICE) having an intake manifold includes a calculator that calculates an estimated mass air flow based on a throttle position and an adjustment module that determines an adjustment value. The adjustment value is based on the estimated mass air flow, an estimated manifold absolute pressure and a measured manifold absolute pressure. A multiplier multiplies the estimated mass air flow by the adjustment value to determine the mass air flow.

摘要： Adjustment to the lubrication rate for a period of time after startup of a two-stroke internal combustion engine, wherein the magnitude of the adjustment over the period of time is determined from an estimate of the degree the lubricant has receded from the moving parts of the engine exposing the moving parts to an elevated potential for wear, and from an estimate of the rate at which lubricant in the engine may be recirculated to the moving parts to reduce the elevated potential.

摘要： An adaptive learning control method is described for regulating the quantity of air inducted into a fuel injected internal combustion engine to achieve a desired air-fuel ratio, where the amount of fuel supplied to each engine cylinder is determined directly as a function of operator demand for engine output. The rotational speed of the engine is sensed, and indication are derived for the actual mass of air inducted into each engine cylinder and for a desired mass of air for each engine cylinder. For the region in which the engine is operating, open-loop and closed-loop values are determined for controlling engine air flow. A previously stored learning correction value corresponding to the engine operating region is obtained, and the quantity of air flowing to the engine is adjusted in accordance with the sum of the open-loop value, the closed-loop value, and the learning correction value. The learning correction value is periodically updated as a function of the difference between the indicated actual and desired mass of air for each engine cylinder, when the engine continuously operates in the region and a predetermined time has elapsed since the engine first began continuous operation in the region.

摘要： A system for a vehicle includes a time stamping module, a period determination module, a stochastic pre-ignition (SPI) indication module, and an SPI remediation module. The time stamping module generates first and second timestamps when a crankshaft of an engine is in first and second crankshaft positions during an engine cycle, respectively. The period determination module determines a period between the first and second timestamps. The SPI indication module selectively indicates that an SPI event occurred within a cylinder of the engine based on the period. The SPI remediation module selectively adjusts at least one engine operating parameter in response to the SPI indication module indicating that the SPI event occurred within the cylinder.

摘要： A system for a vehicle includes a filtering module, an indicated mean effective pressure (IMEP) determination module, and a stuck mechanism indicator module. The filtering module generates engine speeds based on positions of teeth of a toothed wheel that rotates with a crankshaft and based on a crankshaft position signal generated by a crankshaft position sensor. The IMEP determination module determines an IMEP for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds during the combustion cycle. The stuck mechanism indicator module selectively diagnoses a fault in a variable valve lift (VVL) mechanism of the cylinder based on the IMEP.

The disturbance module determines a disturbance value for a past combustion stroke of a cylinder based on rotation of a crankshaft. The misfire threshold determination module determines a jerk value indicative of a misfire within the cylinder. The disturbance ratio module determines a disturbance ratio for the past combustion stroke based on the disturbance value and the jerk value. The spark control module determines a spark timing for a future combustion stroke of the cylinder, determines a spark timing correction for the future combustion stroke based on the disturbance ratio, determines a corrected spark timing based on the spark timing and the spark timing correction, and generates spark during the future combustion stroke based on the corrected spark timing.

摘要： A dilution control adjusts an EGR valve, variable valve lift mechanism or similar dilution control device in an internal combustion engine in response to the relationship between ignition timing and the timing of peak combustion pressure (LPP) in the vicinity of a desired timing of peak combustion pressure (DLPP). The relationship is derived in the process of controlling ignition timing in response to LPP, wherein LPP is controlled to DLPP or as close to it as possible. In this process, LPP varies slightly back and forth through DLPP or through a maximum retard value, if LPP is not attainable. The apparatus detects whether LPP is retarded with respect to DLPP as it reverses from retard to advance, increases dilution if it is so retarded and decreases dilution if it is not. The engine thus operates with maximum EGR consistent with LPP being equal to the desired value DLPP.
摘要翻译：响应于点火正时与峰值燃烧压力（LPP）的期望值之间的关系，在期望的峰值燃烧时刻附近，稀释控制调节内燃机中的EGR阀，可变气门升程机构或类似的稀释控制装置压力（DLPP）。该关系是在响应于LPP控制点火正时的过程中导出的，其中LPP被控制到DLPP或尽可能接近LPP。在这个过程中，如果LPP不可达，LPP会通过DLPP或最大延迟值稍微变动。该设备检测LPP是否相对于DLPP延迟，因为它从延迟反转到提前，如果延迟则增加稀释度，如果不是则减少稀释。因此，发动机以与LPP等于期望值DLPP一致的最大EGR运行。
