Pressure and temperature sensor assembly for internal combustion engines

摘要

A pressure and temperature sensor assembly for internal combustion engines is disclosed. The sensor assembly is formed by integrating a temperature sensor part with a conventional MAP sensor into a single structure. In the temperature sensor part, a temperature sensing rod (23) is formed by partially extending downward the bottom case (7) of a MAP sensor at a portion around the lower end of a pressure inlet port (9) of the bottom case (7). A temperature sensor chip (24) is interiorly installed in the temperature sensing rod (23) and is electrically connected to the connection terminals of the top case (1). The sensor assembly is commonly used for sensing both the internal pressure and inlet air temperature of a cylinder.
