Euro 6 – 1st September 2015

Euro 6 logo Motability CarFrom 1st September 2015 all new cars sold must comply to the Euro 6 emission standard, light commercial vehicles, ie Vans, are given until September 2016 to comply. It has been the case that all new models released since September 2014 have to be Euro 6 compliant.

Euro engine emission standards were introduced in the early 1990s to reduce pollutants from vehicles. They have led to significant improvements in emissions of nitrogen oxides (NOx), particulate matter (PM) and hydrocarbons from passenger cars, vans and trucks. NOx levels remain stubbornly high in cities and the new legislation aims to combat this.

Euro 6 Table Motability Car

The table shows that petrol engines are not affected by Euro 6 and it is only the Nitrogen Oxide levels for diesel engines that are targeted.

Euro 6 logo Motability Car petrolSome Manufactures including Mazda with their SkyActiv engine have lowered NOx levels at source by using Exhaust Gas Recirculation (EGR), where some of the air in the intake gases is replaced with recycled exhaust gas. Another way to reduce the NOx levels is to destroy the bad gases in the catalytic convertor system and release them harmlessly. The third method, and most common, is Selective Catalytic Reduction which is a system using injected Diesel Exhaust Fluid (DEF), or commonly known as AdBlue, stored in a separate tank in the car. The active additive component, urea, reacts to neutralise the NOx in the exhaust gases.

This may well be the first you’ve heard of AdBlue, but it will not be the last, it will become a household name over the next few years. AdBlue is a solution composed of urea and demineralised water. It is non-toxic, colourless, odourless and non-flammable.

Ad Blue Motability carAdblue is consumed at approximately one litre per 625 miles of driving so a typical 20 litre tank will give you 12500 trouble free miles, enough to make it to the next service (unless you drive a VW Sharan when the first service is at 20 000 miles and the warning sounds the moment you get off the ferry in France.) Should your levels drop you will be warned by a light and miles to empty notice, should you ignore this and run out your engine will not start.

Euro 6 Motability car logoYou would have expected most manufacturers to be ahead of the game and made sure their cars are Euro 6 compliant already, the more premium brands are but this is not the case for all manufacturers. There are a great deal of cars that will need new engines over the next few months our advice is to make sure your new car is Euro 6 compliant, not just for the reduction in pollutants you contribute to the atmosphere but because you will be getting the latest technology, more power and almost certainly, and most importantly, better fuel economy.
