Abstract: An apparatus includes a sensor module, an offset diagnostic module, and a notification module. The sensor module is in operative communication with a cylinder pressure sensor and structured to acquire cylinder pressure data from the cylinder pressure sensor indicative of an actual in-cylinder pressure of a cylinder of an engine. The offset diagnostic module is structured to interpret the cylinder pressure data to determine an offset of the cylinder pressure sensor based on a reference in-cylinder pressure and the actual in-cylinder pressure. The notification module is structured to provide an offset error notification responsive to the offset being greater than a threshold offset.

Abstract: An exhaust gas detection assembly, comprising a sensing system comprising a wide-band light source and a detector, a probe configured for mounting in a port of a component of an engine exhaust system, and a fiber optic bundle connected between the sensing system and the probe to carry source light from the light source to the probe and reflected light from the probe to the detector, wherein the detector comprises a filter that passes reflected light received from the probe in a wavelength range corresponding to a wavelength range affected by the presence of a type of gas molecules in the probe.

Abstract: Systems and apparatuses include a passive device coupled to a mounting boss arranged on a vehicle system, and a sensor structured to engage the mounting boss. The sensor includes a probe structured to sense a characteristic of the vehicle system, and a reader structured to send a query signal to the passive device and receive location data from the passive device associated with the mounting boss.
