Engine crankshaft torque sensor cartridge

In various aspects, an engine crankshaft is disclosed. The engine crankshaft comprises a rear bearing journal having an output end. The rear bearing journal defines a cylindrical cavity extending from the output end into the bearing journal. The cavity may intersect oil channels disposed within the crankshaft. A sensor capsule may be disposed within the cavity. The engine crankshaft may comprise at least one torque sensor operatively coupled to the rear bearing journal. The at least one torque sensor may be coated with a sealant to prevent contact with pressurized engine oil. The at least one torque sensor may generate a torque signal corresponding to a torque exerted on the rear bearing journal. The torque exerted on the rear bearing journal is indicative of a torque output of an engine. The at least one torque sensor may be electrically coupled to electrical elements within the sensor capsule.
