摘要： An inspection object constructed of an ignition plug and an ignition coil is inserted in an inspection housing that does not have a ground electrode. A voltage generated in the ignition coil is measured while the inspection object is housed in the inspection housing. Electrical discharge does not occur because the ground electrode is not provided. Therefore, the voltage generated in the ignition coil is properly measured for quality inspection of the ignition coil.

摘要： The invention is a method and apparatus for extracting and analyzing features in real time from primary or secondary ignition waveforms, including engine probes, sampling device, and a processor that extracts from the waveform features such as peak firing height, firing line duration, firing line slope, firing line noise, post firing line duration, primary oscillations, and dwell interval duration and compares them against fixed thresholds and running averages to detect anomalies. Anomalies are reported as they occur allowing diagnosis of transient events as well as steady conditions. Waveforms with or without anomalies may be stored and retrieved as needed.

摘要： A digital engine analyzer has an oscilloscope display and is controlled by microprocessors operating under menu-driven stored program control. The analyzer receives analog input signals from an engine being analyzed. The engine calculates and displays real-time cylinder time balance information by calculating for each cylinder the cylinder time period from the firing of that cylinder to the firing of the next cylinder, storing the cylinder time values for each cylinder for a number of successive engine cycles, averaging the time period values for each cylinder over that number of engine cycles, calculating an overall average of the cylinder averages, calculating the percentage difference between each cylinder average and the overall average and then displaying the percentage differences in both numerical and bar graph form along with the overall average value.

摘要： A digital engine analyzer has an oscilloscope display and is controlled by microprocessors operating under menudriven stored program control. The analyzer receives analog input signals from an engine being analyzed. Peak capture circuitry permits the display of a full cylinder period of a waveform, even though it contains very high frequency portions, by selectively switching between normal and high resolution modes. The circuitry samples the analog waveform at a very high rate and selects samples for display at a much slower display rate. The circuitry captures and stores the highest magnitude sample in each cylinder cycle by storing each sample only if its magnitude exceeds that of the previously stored sample. In the normal mode, at each display clock pulse the most recent sample is selected for display, irrespective of its magnitude. In the high resolution mode the stored peak value is selected for display at each display clock pulse.

摘要： A digital engine analyzer has an oscilloscope display and is controlled by microprocessors operating under menu-driven stored program control. The analyzer receives analog input signals from an engine being analyzed. The analyzer is provided with a scanner interface, so that a scanner designed to read data from a vehicle on-board computer, can transfer this data to the analyzer for display on the analyzer oscilloscope. The analyzer processor, when operating in the scanner interface mode, operates under stored program control to reconfigure analyzer keyboard and soft key functions to duplicate scanner control functions, so that the scanner control functions can be effected from the analyzer.

摘要： An improved automotive ignition analyzer is provided for use with electronic ignition systems. A quadrature field magnetic pickup is utilized to detect signals in the secondary circuit of the ignition system. An adaptor including a voltage clamp is connected to the tachometer lead of the electronic ignition system so that a power balance test may be performed in the conventional manner without harming the electronic ignition system.

摘要： An internal combustion engine performance analyzer is described for simultaneously displaying certain operating characteristics, such as ignition waveform, horsepower output, etc., under controlled operating conditions. A plurality of probes are coupled to the engine to provide output signals representative of engine performance characteristics such as cylinder ignition, generator output, starter current, etc.. To provide output signals representative of additional operating characteristics, a dynamometer and an exhaust analyzer may also be coupled to the engine. The analyzer includes an oscilloscope and at least one selectable scale test meter in which a rotatable drum positions one of six possible scales adjacent the meter indicator or pointer at a time. A multiple position program switch controls the drum position to provide the proper scale and couples selected output signals from the engine, dynamometer or exhaust analyzer to the meters and the oscilloscope for a selected test procedure. The program switch also couples one of several sweep signals to the oscilloscope so that signals, for example, representing the spark plug voltages of the cylinders may be displayed in a superimposed pattern or separated in a vertical or horizontal pattern on the oscilloscope. The program switch enables the operator to diagnosis an engine by simply rotating the switch through each of its positions and reading the values of the parameters under test on the scales positioned adjacent the meter indicators. The waveforms of a selected parameter such as ignition voltages, starter current, etc., are simultaneously displayed on the oscilloscope for each switch position.
