The direct injection diesel engine system was developed to solve the problems of conventional diesel engine systems: emissions of PM (Particulate Matter) and high emissions of NOx (nitrogen oxides). The common rail pressure sensor is a key sensor in the system, which requires high-pressure resistance of 160MPa and accuracy of ±1%. This paper discusses our development of a new generation of common rail system high-pressure sensors that are structurally simpler than conventional sensors, while meeting the above requirements.
