摘要： An exhaust emission control system for an internal combustion engine diagnoses a NOx storage capacity of a NOx storage type three-way catalyst disposed in an exhaust passage. A control unit of the exhaust emission control system includes a calculating section which calculates a quantity of fuel to a cylinder to bring an air fuel ratio of air-fuel mixture closed to a target ratio and to output an injection signal to a fuel injector based on the calculated quantity of fuel, an executing section which executes a rich-spike treatment for temporally enriching the air-fuel ratio of air-fuel mixture supplied to the engine in a lean condition, and a diagnosing section which diagnoses a NOx storage capacity of said NOx storage type three-way catalyst on the basis of a peak value of the air-fuel ratio during the rich-spike treatment.

摘要： In an intra-cylinder injection type engine, a first fuel cut-off starting rotational speed, a first return rotational speed and a first target idling speed in a compression stroke injection mode, which is superior in both combustion and responsivity, are set at lower speeds than a second fuel cut-off starting rotational speed, a second return rotational speed, and a second target idling speed in a suction stroke injection mode. During operation in the compression stroke injection mode, a fuel cut-off mode and an idle running of the engine are practised at low engine speed, to improve fuel economy without causing deterioration of combustion.

摘要： A fuel filter and boost pump apparatus including a filter chamber (203), a fuel filter (247) on the inside of the chamber, and a fuel pump (201) on the outside of the chamber. The chamber has a bottom mounted remotely actuated discharge valve (265). The fuel pump is in fluid connection with the inlet of the fuel filter by means of valves (223, 309). When the fuel pump is not running, these valves cause the fuel flow to bypass the pump and directly enter the inlet of the filter. A water sensor (267) detects water within the filter chamber. The remotely actuated solenoid discharge valve is operated when the water sensor detects a critical level (269) of water in the chamber.

摘要： A method of air-fuel ratio control for automotive internal combustion engine is disclosed, in which the amount of fuel to be supplied to the internal combustion engine is determined in accordance with the amount of air passing through a main air intake path (16), and the amount of air in a bypass (32) is controlled in a manner to attain a predetermined air-fuel ratio for a lean mixture gas which in turn is determined by a predetermined operating mode (81 to 82) of the automobile. The amount of supplied fuel which changes with the amount of air in the bypass is thus corrected to perform the lean mixture gas operation in the predetermined operating mode.

摘要： Es wird eine Einrichtung zur Regelung des Luft Kraftstoffverhältnisses des Betriebsgemisches einer Brennkraftmaschine und zur Überwachung der Betriebsbereitschaft einer die Regeleinrichtung steuernden, nach dem Prinzip der lonenleitung in Festelektrolyten arbeitenden Ä-Sonde vorgeschlagen. Dabei wird der λ-Sonde eine einstellbare konstante Bezugsspannung, die etwa der mittleren Sondenausgangsspannung entspricht, entgegengeschaltet. Die Höhe der sich unter Mitwirkung des resultierenden Stromes einstellenden resultierenden Spannung mit symmetrisch zur Bezugsspannung liegenden Werten wird durch Vergleichseinrichtungen überprüft, deren Ausgangssignal logisch verwertet ein Signal über den Betriebsbereitschaftszustand abgeben. Zur Erzeugung der Bezugsspannung ist ein hochomiger Spannungsteilerzweig parallel zu einem relativ niederomigen Spannungsteilerzweig gelegt, der weiterhin zur Einstellung der Schwellwerte der Vergleichseinrichtungen dient. Durch die Abkupplung von der Stromaufnahme der Vergleichseinrichtungen kann sehr genau die gewünschte Bezugsspannung und somit auch sehr genau der gewünschte Regelpunkt der Regeleinrichtung eingehalten werden.
