When vehicles burn fuel they don’t do it efficiently and it creates undesirable compounds which we call pollution. Vehicle manufacturers are constantly striving to make their engines more efficient with the optimum goal of burnt fuel just producing water, nitrogen and carbon dioxide.<\/p>\n
Governments have passed standards for engine emissions since 1992 when Euro 1 was released. Compared with Euro 1, the current Euro 6 levels are up to 96% less emissions in some of the compounds.<\/p>\n
Euro 1 emission limits (1992):<\/strong><\/p>\n Euro 6 (or Euro VI) emission limits (2015) (petrol):<\/strong><\/p>\n Euro 6 emission limits (diesel):<\/strong><\/p>\n NO and NO2 are released from exhausts. They:<\/p>\n It is:<\/p>\n They:<\/p>\n Hydrocarbons:<\/p>\n Is:<\/p>\n Lead used to be added to fuel to create leaded petrol (hence why we have unleaded petrol now). It interferes with the production of red blood cells, causes high blood pressure and inhibits development in children. Lead no longer appears in exhaust emissions except in a handful of countries that still use leaded petrol. It affects the performance of catalytic converters.<\/p>\n Sulphur dioxide contributes to the formation of ozone and particulate matter. It’s naturally present in petrol at the refining process and is removed. It affects the performance of catalytic converters.<\/p>\n Most vehicles imported into New Zealand must meet approved emissions standards unless they’re either more than 20 years old, are a special interest vehicle, or it’s a car, van or off-road vehicle you’ve owned in another country and you are emigrating here.<\/p>\n Detailed explanations of the emissions standards accepted in New Zealand are available here<\/a>.<\/p>\n As your vehicle’s engine wears out it may start to produce more emissions.\u00a0When you take it for a Warrant of Fitness test it will be check to see if it produces smoke<\/a>. If it does, you may need to get a proper emissions test done.<\/p>\n","protected":false},"excerpt":{"rendered":" When vehicles burn fuel they don’t do it efficiently and it creates undesirable compounds which we call pollution.
