Abstract: An engine synchronisation arrangement of an internal combustion engine having a crank-shaft and a camshaft geared together with a fixed rotation ratio includes a crank-shaft wheel cooperating with a first sensor and, a camshaft wheel cooperating with a second sensor, both wheels being provided with peripheral features. Both sensors detect the features and communicate to an ECU binary signals. The features of the crank-shaft wheel are arranged in a sequential pattern, and a sliding window of a specific width covers a unique set of features corresponding to a unique string of consecutive bits mapping to a unique angular position of the crank-shaft.

Abstract: A power take-off (PTO) system for a motor vehicle includes a PTO housing. The PTO housing is mounted to a transmission case. A disconnect clutch assembly is positioned within the PTO housing acting when supplied with a first volume of a pressurized oil from the transmission case to engage an output shaft member. A controlled lube oil circuit is isolated from the first volume of the pressurized oil. The controlled lube oil circuit supplies a second volume of the pressurized oil directly to the disconnect clutch assembly to lubricate the disconnect clutch assembly. A lube oil drain return is connected to the PTO housing. The lube oil drain return receives oil that collects inside the PTO housing to be returned to the transmission case.
