Abstract

A pressure measuring device/system that is capable of measuring the pressures of multiple systems in an automobile, including cylinder pressure, fuel pressure, transmission oil pressure, and engine oil pressure, and is capable of displaying and/or recording the measured pressure values remote from the device taking the measured remote pressures. The pressure measuring system has a remote interface and a sensor configured to communicate wirelessly with each other. The interface may be configured to be included within the device purpose built for displaying and interacting with the pressure values measured by the sensor. Additionally or alternatively, the interface may be configured to be downloaded as a mobile application “app” on a smartphone or other similar device.

Claims

1. A wireless testing system for measuring target operational parameters of a motor vehicle, the wireless testing system comprising:

a housing, and a coupling between said housing and said motor vehicle;

a sensor carried by said housing;

a communicative coupling carded by said housing for coupling the housing with the portion of the motor vehicle to be analyzed to allow said sensor to measure a targeted operational parameter of said motor vehicle;

a remote user interface wirelessly coupled to said sensor;

a local user interface carded by said housing and coupled to said sensor;

a control panel carried by said housing, said control panel operatively coupled with said sensor, said sensor sensing a signal from said motor vehicle comprising at east one of cylinder pressure, fuel pressure, transmission oil pressure, and engine oil pressure;

said remote user interface receiving said signal while said motor vehicle is in moving operation.

2. A wireless testing system according to claim 1, said a coupling between said housing and said motor vehicle comprising a magnetic coupling.

3. A wireless testing system according to claim 1, said remote user interface comprising a mobile phone.

4. A wireless testing system according to claim 1, said local user interface comprising a readout carried by said housing, and a plurality of controls comprising switches for varying at least one of settings, units, modes, and cylinders.

5. A method of measuring target operational parameters of a motor vehicle, method comprising:

providing a sensor sensing a signal from said motor vehicle comprising at least one of cylinder pressure, fuel pressure, transmission oil pressure, and engine oil pressure;

coupling said sensor to an engine compartment of said motor vehicle;

transmitting readings wirelessly from said sensor to a remote user interface spaced apart from said sensor in an interior region of said motor vehicle, physically separate from said engine compartment of said motor vehicle;

logging said readings with said remote user interface while said motor vehicle is in moving operation.
