摘要： An apparatus and method for converting a fuel injected internal combustion engine normally operated with a conventional fuel such as gasoline to operate with an alternative fuel are disclosed. The apparatus comprises an alternative fuel introduction assembly having at least one alternative fuel injector, a temperature sensor, and an electronic translator. The electronic translator is adapted to receive conventional fuel injector control signals generated by an electronic control module, and to receive an output signal from the temperature sensor. The electronic translator then calculates an alternative fuel injector control signal to facilitate the supply of a required energy amount of the alternative fuel. The calculation is based upon the energy content of the alternative fuel, the temperature of the alternative fuel, and the flow and operating characteristics of the alternative fuel injector relative to a conventional fuel injector. Preferably, the alternative fuel is natural gas.

摘要： A device for the angular adjustment of a camshaft of a combustion engine according to speed and load conditions and to the angular position of the camshaft with respect to a driving wheel being controlled by an adjustable mechanism. The technical problem is the angular adjustment of the single or multiple camshafts with respect to the crankshaft according to speed and load conditions. Tooth pulses, or counting pulses, corresponding to the angular position of the crankshaft (2) and reference pulses corresponding to a particular angular reference position (singular tooth) are generated by a transducer, or pulse generator, controlled by the toothed ring associated with the crankshaft and the ignition circuit (13). An address counter (10) is reset by the reference pulses and incremented by the tooth pulses so that the output of the counter provides digital address signals corresponding to the actual angular position of the crankshaft (2). The output signals of the address counter and digital signals corresponding to load conditions are input to a correction processor with memory, (20) the output of which provides a camshaft adjustment signal. During pre-set engine operational periods, a buffer memory ( 21), controlled by the tooth-pulse time base signal, stores an adjustment signal used as a camshaft correcting variable, which is then delayed under asynchronous clocking and fed into an electromechanical control device (FIG. 3) which effects a rotary-then-linear displacement of a control member (31) and subsequently an angular corresponding displacement of the camshaft(s) to the correcting variable.

摘要： An electronic controlled carburetor includes sensors for sensing engine speed, intake air pressure and water temperature. An arithmetic unit digitally processes output signals from the sensors and generates signals for controlling the air-fuel ratio of a mixture supplied to an engine on the basis of the output signals from the sensors. The carburetor system includes means for sensing atmospheric pressure and intake air temperature, and means for adjusting at least one of the amount of intake air of the engine and the amount of fuel. The arithmetic unit digitally processes the output signals from the atmospheric pressure and the intake air temperature sensing means to thereby produce a signal representing air density change and automatically controls at least one of the amount of intake air and fuel on the basis of the air density changing signal, to thereby control the air-fuel ratio of the mixture with higher accuracy.

摘要： A command signal drives a carburetor metering valve to provide the carburetor fuel flow which will establish a desired air-fuel ratio; simultaneously, the command signal drives a control unit which purges fuel vapor from a fuel vapor storage region. The control unit minimizes purge flow when either maximum fuel flow or minimum fuel flow is commanded and maximizes purge flow when an intermediate fuel flow is commanded; accordingly, fuel vapor is purged from the vapor storage region only when the purge flow cannot unduly enrich or unduly lean the mixture.
