초록 ▼

Diagnosis of an electronically fuel-injected engine equipped with sensors connected to an on-board microcomputer. Use of a standard personal or portable computer and a connector for electrical connection to the sensors and the on-board computer. An interface device is connected between the connector and the computer to enable the computer to read the values of the operational parameters of the engine as detected by the sensors, and to perform a diagnostic software comparison of the measured values with predetermined values or ranges. The interface device is switchable to a selected sensor or the on-board computer under software control from the computer, and includes a multiple mode measurement device which is also selectively switched to a desired measurement mode by the computer. The computer is then able to selectively measure the operational parameters of the engine, test for correct operation, and display the appropriate diagnostic or tutorial instructions for fault location and rectification. The computer is also able to feed data to the on-board computer for testing same.

대표청구항 ▼

Apparatus for diagnosing an internal combustion engine having a plurality of sensors connected to an on-board microcomputer via a two-part multiwire connector, the apparatus comprising: external computer means having an associated display screen; input means having a multiple input connector connected between the two parts of the multiwire connector, and first switching means responsive to the computer means for selectively connecting each input of the multiple input connector to a respective sensor and the respective sensor\s connection to the on-board computer; and an interface circuit connected between the computer means and the input means, the interface circuit comprising a multiple-mode measurement means responsive to the computer means to switch to a selected measurement mode, second switching means responsive to the computer means to selectively connect the measurement means to a selected input of the multiple input connector, an analog-to-digital converter for converting to digital form the value, as measured by the measurement means, of an operational parameter sensed by a sensor corresponding to the selected input, and output means for outputting the digitised measured value directly to the computer means; wherein in use, the computer means is programmed to perform a diagnostic comparison of the measured value with a predetermined operating range and to display the result of such diagnostic comparison on the display screen.
