Abstract
An apparatus measures temperature of a reciprocating piston and comprises one or more thermocouples of which one end is inserted to a predetermined point of the piston and generates a potential difference according to temperature of the predetermined point. A telemetry unit is mounted on a big end of a connecting rod, computes the piston temperature on the basis of the potential difference, and wirelessly transmits the piston temperature signal.
Claims20
An apparatus for measuring temperature of a reciprocating piston inside an engine, comprising:
- one or more thermocouples of which one end is inserted into a predetermined point of a piston and that generates a potential difference according to temperature at the predetermined point;
- and
- a telemetry unit, which is mounted on a big end of a connecting rod, computing the piston temperature on a basis of the potential difference and wirelessly transmitting a signal of the piston temperature.
An apparatus for measuring piston temperature, comprising:
- at least one thermocouple wherein one end portion of said thermocouple is housed within a piston pin and an operational end of said thermocouple is coupled to a piston near the piston pin such that the thermocouple generates a potential difference of piston temperature near the piston pin;
- and
- a telemetry unit coupled to an end of a connecting rod wherein said telemetry unit computes a piston temperature based on the potential difference and transmits the piston temperature through a wireless communication.
A system of measuring piston temperature, comprising:
- a piston;
- a connecting rod having a first end and a second end;
- a piston pin configured and dimensioned to couple said piston near the first end of said connecting rod;
- a thermocouple having a portion received by said piston pin and an end portion of said thermocouple is coupled with said piston for measuring a piston temperature of said piston;
- and
- a telemetry unit coupled near the second end of said connecting rod wherein said telemetry unit is configured and dimensioned to receive the measured piston temperature from said thermocouple and transmit a signal of the measured piston temperature to a remote location.
