If you don’t know what Euro 4 and Euro 6 are, these are the European Emission Standards, with Euro 6 being introduced in 2015. The standards have been set up in place to protect the environment and reduce the level of emissions, especially carbon oxide, particulate matter, and nitrogen oxides.
But how to actually take your car from Euro 4 to Euro 6? Let’s find out!
How to convert from Euro 4 to Euro 6?
If your car is running on standard petrol, retrofitting your car will most probably not be a viable solution. It’s often too complex to integrate a solution that lowers emissions to a ęsatisfying level in cars with petrol engines, making the conversion very expensive, if even possible.
Switching to LPG might be one solution, but it’s not only costly, but also comes with a range of downsides. A standard LPG conversion might cost you up to £2,000, and while you’ll save a lot on fuel costs, there are tons of additional regulations that LPG cars have to abide by, like not being able to use underground car parks. You might also convert to an electric engine, but that’s going to cost you around 10 times as much as an LPG conversion would, which doesn’t make much sense with older vehicles.
However, if you’re an owner of a Diesel vehicle, you’re in luck - there might be a way of handling Euro 4 to Euro 6 conversion at a low cost.
Euro 4 to Euro 6 conversion in Diesel vehicles
Since lowering emission in Diesel cars often boils down to changes in the exhaust system, it’s much more affordable than in petrol cars. While some older vehicles will need a full SCR system conversion, others might do with a simple change of the NOx sensor.
As NOx sensors tend to be faulty and easily damaged, and their repair and replacement is very expensive, drivers opt to use an NOx emulator instead. It’s an easy and cheap way of fixing your NOx sensor, without permanently interfering in your car’s electronics.
Additionally, investing in a NOx emulator can help your car meet the Euro 6 emissions standard, especially if you’ve tampered with your car’s ECU - it’s definitely worth a try, potentially saving you thousands in expensive conversions!
