Spark plug with pressure sensor
Germany’s Imes has developed the ISP-01 IMES spark plug, calling it an innovative dual-function component that integrates a miniaturised pressure sensor into a long-life spark plug, enabling real-time pre-chamber pressure measurement for combustion optimisation, emission reduction, and condition-based maintenance in gas engines. The main users of IMES cylinder pressure sensors are original equipment manufacturer customers of large gas engines for the auxiliary and main propulsion of ships and power plants, which can also be operated with alternative fuels such as methanol, ammonia or hydrogen in the future....
