Self-locking cam washer
13 Apr 20
A cam washer for a vehicle suspension system includes a point of rotation about which the washer is configured to rotate, and an outer surface profile where any point along the outer surface profile is configured to provide a friction angle less than a predetermined value to prevent the cam washer bolt from rotating under a load acting on the outer surface profile, the outer surface profile being a function of: i) a shortest distance from the point of rotation to the outer surface profile, ii) a longest distance from the point of rotation to the outer surface profile, iii) a position angle of the outer surface profile, and iv) a coefficient of friction of a material of the washer.

A system and method of utilizing a pre-turbine wide-range oxygen (WRO2) sensor during both individual cylinder fuel control (ICFC) and scavenging of a turbocharged engine involve receiving, by a controller and from the WRO2 sensor arranged in an exhaust system of the engine at a point upstream of a turbine of a turbocharger of the engine, an unfiltered WRO2 signal indicative of a fuel/air (FA) ratio of exhaust gas produced by the engine, performing, by the controller, ICFC by controlling the engine using the unfiltered WRO2 signal, performing, by the controller, engine cycle average filtering of the WRO2 signal to obtain a filtered WRO2 signal, and, while the engine is scavenging, performing, by the controller, engine FA ratio and emissions control using the filtered WRO2 signal.
