The article discusses Power Skills Organization's (PSO's) role in developing the training framework for the Energy sectors, encompassing gas, renewable energy, and electricity generation and distribution. Topics include identifying skills and workforce requirements, mapping career pathways, developing vocational education and training (VET) products, fostering collaboration between industry and training providers, and serving as a source of intelligence on sector-related issues.

Gasoline particulate filters (GPF) recently entered the market and are already regarded as state-of-the-art for gasoline exhaust aftertreatment systems to enable EU6d-TEMP fulfillment and beyond. Due to its rapid market introduction, the field of GPF lifetime evaluation is still open for research. In this context, the paper describes the advantages of a method for accelerated investigation of filter ash loading during the development of particulate filters. The central task is the simulation of real-world lubrication oil consumption and combustion, which is the major source of ash in the exhaust gases. For that purpose, a burner test bench designed for catalyst aging was additionally equipped with an oil injection unit. The injection unit enables control of the oil volume and the droplet sizes as precursors for the ash particulates. The results obtained with the new filter aging method are compared with data from vehicle endurance runs and with burner test investigations in which the fuel is doped with oil. The latter method is currently considered as the state-of-the-art method for accelerated ash generation. The new method proofed to be vehicle-equivalent in terms of ash-induced backpressure, filtration efficiency, wall ash layer formation, and wall/plug ash ratio. In this context, it turned out that it is important not to atomize the oil droplets too far, since smallest particulates accumulate mainly at the walls and cause unrealistically high backpressures. Furthermore, the ash loading process should include different mass flows in order to achieve stable backpressure results.

The most difficult part of making any tablesaw sled is attaching the miter runner(s) accurately so that the fence is square to the blade. If the sled has moved slightly off square, you can make a small adjustment by loosening the head of the miter gauge as well as the front screws that attach it to the sled, and tapping the front end of the sled sideways. Standard miter gauge of decent quality If sled isn't quite square to blade, loosen head of miter gauge, loosen pan-head screws that attach it, tap front end of the sled sideways, and retighten everything.
