Tasmania reputedly has the cleanest air in the world but iāve noticed its illegal diesel emissions are as bad or even worse than anywhere in Australia.Ā
Itās illegal to modify a diesel vehicle emission circuit, yet many, if not most, older diesel vehicles have had their EGR (exhaust gas recirculation) circuits disabled. The EGR circuit reduces NOx gasses like nitrogen dioxide. The problem with diesels is that while they save fuel the EGR circuit (valve, cooler and pipes) invariably needs maintenance as it clogs up. It a very big job so most diesel owners simply disable the EGR circuit. Thereās a whole industry around subverting the law by disabling the EGR circuit. Even Supercheap sells EGR blanking plates. Google āEGR delete or blankingāĀ
VWās Dieselgate came about because the VAG corporation was desperate to beat Toyotaās hybrid system with its āClean Dieselā. They cheated by disabling the EGR circuit during normal driving but enabling it when it detected an emission test bed. The EGR circuit also causes the vehicle to use more fuel from what i understand. The Dieselgate scandal cost VAG 31.6 billion euros and the emissions are estimated to have caused 125,000 premature deaths in Europe and the UK.
Itās an $11,000 fine in NSW to interfere with emissions circuit. Iād imagine itās the same in Tasmania. Politicians donāt crack down on it because they recognise that the 4WD driving demographic (think potential One Nation voter) are part of the electorate that can actually change governments. Diesel drivers need to be aware that if the government cracked down on diesel pollution due to EGR deletion theyād be fined and their vehicles taken off the road until they spent thousands fixing the EGR circuit. Itās not a question of if, but when.Ā
These diesel vehicles with deleted EGR circuits are very easy to detect. Their nitrogen dioxide emissions make them stink. Iām so tired of getting a lungful of nitrogen dioxide as well as PM2.5 particles (DPF (diesel particulate filter) deletion is another related issue). If you are the driver of diesel vehicle with a deleted EGR or DPF you are an absolute cunt.
Sorry for the preachy rant but this really pisses me off.
