An apparatus for electrically controlling the spark advance of selected cylinders of a multicylinder engine so that the spark of the selected cylinders is advanced beyond others of the cylinders. For example, the selected cylinders may be advanced beyond normal operational advance to increase combustion chamber temperatures and pressures for a relatively short period so as to clean the surfaces of the combustion chamber. The cylinders which are advanced are changed in sequence or at random so that all of the cylinders are cleaned. The system may also be used to control the spark advance of the cylinders to provide differing advances for the respective cylinders to accommodate differences in operational conditions at the cylinders.

Internal combustion engine ignition system

A transponder/interrogator system for remotely identifying objects. The interrogator emits infrared pulses to activate and remotely clock the transponder. Upon such activation, the transponder emits in synchronism with the interrogator pulse a unique code in the form of infrared pulses in accordance with a program stored in a recirculating shift register. The interrogator receives the infrared pulses from the transponder and may be associated with various code utilization devices as described herein.

Object identification system

A dual path analyzer and a single path analyzer are disclosed, each for determining the concentration of one or more gaseous components in a mixture of gases. The preferred analyzer is a single path instrument which includes a source of infrared energy, a detector for the energy, a sample cell for the gas mixture positioned between the source and detector, and a filter wheel having a plurality of filters and a source blocking device positioned between the sample cell and detector for sequentially interposing the filters and the source blocking device between the source and the detector. Means are provided for amplifying the output signal of the detector and for processing the signal to provide a direct readout display which indicates the concentration of the gaseous components being analyzed. The processing electronics preferably include provision for calibrating the analyzer with clean ambient air, for compensating for background levels of radiation, and for correcting the displayed output signal for the effects of absorption band interferences between two or more gases in the gas mixture. The structure of the dual path analyzer includes a source of infrared energy, a detector for the energy, a sample cell for the gas mixture, a cell for a reference gas, and optical path means between the source and detector for sequentially directing the source energy through the sample cell, the reference cell, and through neither cell. Processing electronics similar to the single path instrument can be incorporated to compensate for background radiation and absorption band interferences.
