Over the past decade, engine and turbo technology have increased in complexity and decreased in size as vehicles have been designed, and redesigned, to meet emissions regulations. And where previously, the precision of the settings of the sensitive mechanisms in variable nozzle (or variable geometry) turbochargers was important, it is now absolutely paramount to be accurate. If you want a turbo to operate efficiently, or in fact at all, you cannot guess at the vane setting position for air flow, or risk catastrophic vibrations with an unbalanced core assembly. The Australian Mining Review spoke to GCG Turbos director Brett Lloyd to get the lowdown on building and maintaining these highly sensitive set-ups. According to Brett, the average turbo repair facility…

In 2013, the NSW government released a report analysing all underground metalliferous mine fire incidents from 2008-2012. During this period 128 fires were reported at underground metalliferous mines for an average of 26 underground fires per year, of which mobile plant accounted for 76% of those fires. The report goes on to mention that 20% of all reportable incidents were fire related, and that fire comprised about 25% of all reportable incidents regarding mechanical plant. Of these, 18% were reported as resulting in damage to plant. Thankfully, there was only one fire-related injury during this period. The report also highlighted that the most common heat sources for fires are the exhaust system, engine surfaces and turbochargers, while the most common…

A diesel particulate filter (DPF) is part of a modern diesel engine’s exhaust system and is designed to trap dangerous and toxic metal particles before the enter the atmosphere and human lungs in the vicinity. Diesel particulates are associated with a number of serious health conditions and diesel engine manufacturers are required to contain and eliminate those particles in the interests of worker safety and environmental responsibility. Inside the housing of the filter is a substrate comprising thousands of tiny cells that allow exhaust gases to pass through them but trap the diesel particulate matter.  At various stages of the driving cycle, the on-board computer initiates a regeneration sequence that increases the temperature inside the DPF to 600°C, which converts…
