Abstract

A device for testing exhaust emissions of an internal combustion engine utilizes wireless real time data transfer to permit outdoors testing via an indoors base station (14). A hand portable display device (18) provides instructions to an operator, and a gas sensor/analyser (16) detects combustion gas content. The base station, display device and sensor/analyser preferably communicate by radio.

Claims

1. A device for testing the exhaust emissions of an internal combustion engine and comprising a base station, an exhaust gas sensor, and a hand portable display device having data input terminal, wherein said base station, sensor and display device include at least one of a wireless real-time data transmitter and receiver whereby data can be transmitted and received therebetween.

2. A device according to claim 1, wherein said at least one wireless real-time data transmitter and receiver uses radio signals so that data can be transmitted and received therebetween.

3. A device according to claim 1, wherein the gas sensor includes a gas analyser.

4. A device according to claim 1, wherein the base station includes a memory and printer.

5. A device according to claim 1, wherein a docking port is provided on the base station for said gas sensor.

6. A device according to claim 5, wherein said docking port includes a heater whereby said sensor can be maintained at a desired operating temperature.

7. A device according to claim 5, wherein said docking port is adapted to transfer data between the base station and the gas sensor.

8. A device according to claim 1, and further including a docking port for the display device.

9. A device according to claim 8, wherein said docking port orientates the display device for use on the base station.

10. A device according to claim 1, and further including an engine oil temperature probe having at least one of a wireless real-time data transmitter and receiver for communicating with the display device.

11. A device according to claim 1, wherein the base station includes a smart card access device for enabling a test routine.

12. A device according to claim 1, and further including an engine speed sensor having at least one of a wireless real-time data transmitter and receiver for communicating with the display device.

13. A device for testing the exhaust emissions of an internal combustion engine and comprising a base station, an exhaust gas sensor, and a hand portable display device having data input terminal, wherein said base station, sensor and display device further include at least one of a radio transmitter and receiver whereby data can be transmitted and received therebetween.

14. A device according to claim 13, wherein the gas sensor includes a gas analyser.

15. A device according to claim 13, wherein the base station includes a memory and printer.

16. A device according to claim 13, wherein a docking port is provided on the base station for said gas sensor.

17. A device according to claim 16, wherein said docking port includes a heater whereby said sensor can be maintained at a desired operating temperature.

18. A device according to claim 16, wherein said docking port is adapted to transfer data between the base station and the gas sensor.

19. A device according to claim 13, and further including a docking port for the display device.

20. A device according to claim 19, wherein said docking port orientates the display device for use on the base station.
