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： An internal combustion engine with a throttle valve, fuel supply and dilution (EGR) control includes apparatus effective to detect a throttle tipout condition comprising a rate of throttle closing exceeding a predetermined reference rate and decrease the dilution from the scheduled value to its minimum value during the existence of the throttle tipout condition and further apparatus effective to detect the end of the throttle tipout condition and return the dilution to its scheduled value at a controlled rate. Thus, a sudden unscheduled increase in dilution caused by a throttle tipout associated increase in intake manifold vacuum is reduced and driveability improved.

摘要： An internal combustion rotary engine is disclosed having leading and trailing spark plugs with their respective spark electrodes arranged in peripherally spaced ignition openings in the inner peripheral wall of the engine's rotor housing. The leading ignition opening is located in a zone where the leading apex seal of the passing chambers experiences a relatively low pressure differential which decreases in the direction of rotor rotation whereas the trailing ignition opening is located in a zone where the trailing apex seal of the passing chambers also experiences a relatively low pressure differential but which increases in the direction of rotor rotation. Both plugs are fired at the same time by an ignition system that provides a predetermined relatively fast rise time spark ignition potential and an arc of predetermined relatively prolonged duration which is either substantially constant with respect to engine speed or varies inversely therewith and is determined according to the time available from start of ignition to when the trailing apex seal of the passing chambers reaches the trailing plug.

摘要： An LPP ignition timing control for an internal combustion engine of the type having a normal combustion mode characterized by combustion pressure peaks compatible with closed loop LPP ignition timing control and an abnormal combustion mode which may not be so compatible includes a closed loop control apparatus effective to sense LPP in the combustion chamber, generate an LPP value therefrom, store a DLPP value indicative of a desired LPP, and compare the LPP value and stored DLPP value and adjust ignition timing to reduce the difference therebetween. During a sensed abnormal combustion mode, the control changes the ignition timings for ignition events toward predetermined, stored ignition timings and substitutes for the stored DLPP value temporary DLPP values which are a predetermined crankshaft angle in advance of the generated LPP values and limited in the retard direction to the stored DLPP value. After the termination of the abnormal combustion mode the control continues the substitution of the temporary DLPP values for the stored values until the former comes within a predetermined crankshaft angle of the latter. The abnormal combustion mode may be sensed as excessive variation in LPP, excessively advanced average LPP or excessive numbers of undetected combustion pressure peaks.
摘要翻译：具有正常燃烧模式的内燃机的LPP点火正时控制，其特征在于与闭环LPP点火正时控制兼容的燃烧压力峰值和可能不兼容的异常燃烧模式，包括有效地在燃烧室中感测LPP，从其生成LPP值，存储指示期望LPP的DLPP值，并比较LPP值和存储的DLPP值，并调整点火正时以减小其间的差。在感测到的异常燃烧模式期间，控制将点火事件的点火正时改变为预定的存储的点火正时，并将所存储的DLPP值临时DLPP值替换为所生成的LPP值之前的预定曲轴角度，并且在延迟中被限制指向存储的DLPP值。在异常燃烧模式终止之后，控制继续替换存储值的临时DLPP值，直到前者处于后者的预定曲轴角度内。可以将异常燃烧模式检测为LPP中的过度变化，过高的平均LPP或未检测到的燃烧压力峰值的过多数量。

摘要： The air/fuel ratio of the combustion mixture in the cylinders of an engine is sensed and the sensed air/fuel ratio is controlled to a predetermined scheduled air/fuel ratio by controlling the amount of exhaust gases recirculated. When the exhaust gas recirculated is substantially zero, the air/fuel ratio is thereafter closed loop adjusted to a predetermined scheduled minimum air/fuel ratio when the sensed air/fuel ratio is less than the minimum and when the sensed air/fuel ratio is greater than the minimum while the operator command is at a maximum to thereby provide precise fuel limiting at a predetermined fuel limit schedule.
