摘要： A linearly moving external part of a multi-cylinder internal combustion engine is contacted with a hand-held contact tachometer for producing a waveform signal which, along with a signal responsive to the ignition of each cylinder, are applied to an engine analyzer processor for display of a single engine cycle of the waveform signal on the CRT oscilloscope of the engine analyzer. The variations and amplitude of the waveform signal correspond to speed variations of the moving part over an engine cycle to give an indication of the relative power contributions of the individual cylinders. Cylinder ignition markers and cylinder zone markers are respectively displayed at the top and bottom of the screen, respectively corresponding to the cylinders in their ignition order. Each cylinder zone marker is delayed a predetermined time from its corresponding cylinder ignition marker and indicates the time period during which the engine responds to the ignition event of the corresponding cylinder.

The waveform pattern data derived form the analog input signals is stored in a dual bank waveform memory and read out for display on the CRT screen under hardware control, and address data representing alphanumeric data and screen formats for the various operating modes to be displayed is stored in a dual bank display memory for application to a character generator, a bank switching arrangement being used for both the waveform memory and the display memory to enable the banks of each memory to be alternately written to and read from.

摘要： The apparatus comprises a combustion sensor to sense the combustion event in an engine, and a magnetic sensor to sense top dead center. Electrical signals from the sensors are converted to two trains of pulses which are applied to a microprocessor. Under the stored program, the microprocessor determines the time between pulses in one train and converts such time into engine speed in rpm. Also, the microprocessor determines degrees of rotation between corresponding pulses in the two trains. The offset angle, which is applied to a keyboard is subtracted from the degrees of rotation to provide the timing angle. The engine speed and timing angle appear in digital displays.

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： A refrigerant charging system and method for charging a refrigeration system with a vapor-phase refrigerant includes a refrigerant source, an input line, a sensor and a pressure regulator. The input line connects the refrigerant source to the refrigeration system. One or more valves are disposed between the refrigerant source and refrigeration system to regulate the pressure of the refrigerant being introduced into the refrigeration system, and the sensor measures the pressure of the refrigerant entering the refrigeration system. A pressure regulator can also be used to regulate the flow of refrigerant. Once the pressure of the refrigerant reaches a predetermined pressure, the refrigeration system is fully charged, and the transfer of refrigerant to the refrigeration system is stopped. The system and method are used to charge the refrigeration system of, e.g., an automotive vehicle, and the refrigeration is carbon dioxide.
