Abstract

The invention provides a wireless measuring device for internal combustion engine piston temperature, which comprises a resistor temperature detector, a Teflon wire, a wireless transmission module, a receiving antenna, a data receiving module, and a computer. The wireless transmission module adopts high temperature epoxy resin that is adhered to the connection rod body and the switch is connected with the wireless transmission module. The receiving antenna penetrates into the engine cylinder through the signal hole processed at the engine oil bottom housing. The receiving antenna is connected with the data receiving module. The data receiving module is connected with the computer. The wireless measuring method and the device for internal combustion engine piston temperature proposed by the invention are based on Bluetooth transmission, which increases the measuring reliability and reduces the measuring difficulty. Properly designed, the device is practical in use and of great application value. Suitable for the real-time measurement of the temperature on the surface of the piston, the device can be applied conveniently to the performance estimation and optimization under the different working conditions of the piston.

Description

technical field [0001] The invention relates to the technical field of engine testing, in particular to an internal combustion engine piston temperature measuring device based on Bluetooth wireless transmission. Background technique [0002] With the enhancement of people's environmental awareness and the implementation of stricter emission regulations, engine manufacturers have higher and higher requirements for engine thermal efficiency. Although engineers reduce the piston mass and friction by reducing the thickness of the piston, this puts forward higher requirements for the strength and durability of the piston. At the same time, the current direct injection method needs to be configured with the compression ratio to meet the fuel economy and low emission of the engine to the greatest extent. As an important factor in the working of the piston, the temperature can directly show the performance of the piston under different working conditions. By determining the temper...
