EURO 6, DIESEL ENGINES AND SELECTIVE CATALYTIC REDUCTION: WHAT IS DEF, HOW TO REFILL AND FAQs

We explain what Euro 6 emissions legislation means for our cars, our drivers and the environment.

WHAT IS EURO 6?

Euro 6 is a piece of European Legislation aimed at making cars more environmentally friendly by limiting their exhaust emissions. The legislation sets restrictions on how much nitrogen oxide (NOx) and hydrocarbon gases may be emitted per kilometre by a road vehicle.

Petrol and diesel cars are subject to different restrictions under the new Euro 6 legislation. For diesel cars, the permitted level of NOx emissions has been brought down to 80 mg/km (from 180 mg/km), while the permitted level of hydrocarbons emissions has been brought down to 170 mg/km (from 230 mg/km). The permitted level of NOx emissions for petrol cars remains at 60 mg/km, while the permitted level of hydrocarbons emissions remains at 100 mg/km.

Along with other car manufacturers, Jaguar is legally obligated to comply with these new regulations by the following dates:


  • From 1st January 2015, all newly introduced vehicles must meet Euro 6 standards. This includes any new models on the market, for example: Jaguar XE

  • Vehicles already on sale must comply with Euro 6 by 1st September 2015, but;

  • Individual vehicles already on sale that were built by, and dispatched from, the manufacturer before 1st June 2015 can continue to be sold until 1st September 2016. However, the manufacturer must apply for derogation in these instances.

PETROL AND DIESEL EMISSION STANDARDS IMPROVEMENT 2000 – 2014

Technical innovations have helped to lower vehicle emissions over the last 15 years. Since 2000, NOx limits for diesel engines have reduced by 84% and particulates by 90%.

The table below outlines the reductions:

2000 - Euro 3 2005 - Euro 4 2009 - Euro 5 2014 - Euro 6
Petrol Diesel Petrol Diesel Petrol Diesel Petrol Diesel
CO (g/km) 2.3 0.64 1.0 0.50 1.0 0.50 1.0 0.50
HC (g/km) 0.2 0.10 0.10 - 0.10 - 0.10 -

DIESEL OR PETROL ENGINES: WHAT YOU NEED TO KNOW

Diesel and petrol engines both have emissions that impact on the environment. In recent years, significant investment by the automotive industry has seen the environmental impacts of engines using either fuel reduced. Jaguar is committed to investing in a variety of fuel types to continue this advancement. The choice between petrol and diesel is a personal one. You might consider financial factors such as price and running costs, lifestyle factors such as how often you travel and how long your journeys are, or environmental considerations. -Today, diesel cars deliver around 25% better fuel economy and less CO2 emissions than equivalent petrol counterparts. -The latest diesel cars are the cleanest in history, with high tech filters capturing hydrocarbons, carbon monoxide and 99% of all soot particles. -Since 2002, buyers choosing diesel have saved almost 3 million tonnes of CO2 from going into the atmosphere. -Diesel engine cars typically have a lower total cost of ownership (factoring in fuel costs, servicing costs, resale value and taxation) than petrol engine cars.

WHAT IS SELECTIVE CATALYTIC REDUCTION, AND HOW WILL IT HELP?

Selective Catalytic Reduction is an after-treatment system active in the exhaust, which converts NOx gases into less harmful gases or water. This is made possible by AdBlue®, a special Diesel Exhaust Fluid (DEF). DEF is an aqueous urea solution (made of 32.5% urea and 67.5% deionized water), which is injected into the exhaust flow. This process produces ammonia, which in turn breaks down up to 98% of the NOx into nitrogen or water. Only a very small amount of DEF is needed for this process to work.

WHAT ELSE THIS MEANS FOR YOU?

For the Selective Catalytic Reduction system to work, the AdBlue® levels in the vehicle’s DEF tank must be properly maintained. Each vehicle’s DEF tank has been designed to limit the need for refills outside of standard service intervals. On average, for All-New XF and XE, one litre of DEF is used for every 550 km you drive. For F‑PACE, one litre of DEF is used for every 400 km (although this can vary depending on driving style). The size of the DEF tank varies by model, between 9 and 17 litres, which means you can drive anywhere between 5,000 to 9,400 km before you need to refill the tank. Refer to your model handbook for more information about your vehicle’s DEF tank.
WHAT ELSE THIS MEANS FOR YOU?

DEF/AdBlue re-fills are covered in all Jaguar Diesel Service Plans between regular service cycles at any Jaguar Land Rover approved service centre. Models with Ingenium engines may also need a top-up before the next servicing is due.

HOW WILL I KNOW WHEN DEF LEVELS ARE LOW?

The Selective Catalyst Reduction systems constantly monitors DEF tank quantity levels. You’ll be alerted many times when low levels of DEF are detected. The first alert will be shown 1,500 km before the tank is empty, and the second alert will be shown 930 km before the tank is empty. When the tank reaches 515 km, you’ll be given a warning stating that the vehicle will not start if the tank is not replenished before the distance countdown reaches zero. A final warning will be displayed 100 km before the tank is empty. Once the countdown reaches 0 km, the vehicle will not restart after the next time you switch off the engine, in line with legislation. The DEF quality and flow rate are similarly monitored. You will be notified if the system detects inferior DEF quality or a malfunction, starting with an alert that gives you 530 km to correct the problem. Once more, the vehicle will not restart if you don't take corrective action in this period.

HOW DO I FILL UP THE DEF TANK OR FIX A FAULT?

Outside of regular service intervals, there are two ways to replenish your vehicle’s DEF levels:


  • Jaguar Service Plans offer free DEF/AdBlue® Top-Ups between regular service cycles at our Jaguar Land Rover approved service centres

  • Alternatively, please call your Retailer to arrange a refill to Manufacturer level

  • Look here to find your nearest service centre


You can also top up DEF levels yourself if they are critically low. This will give you some time to arrange professional replenishment.

  • You will need to buy two Jaguar Land Rover-approved AdBlue® refill bottles from Jaguar Land Rover retailers or independent auto shops. Make sure you buy either the ISO 22241-1 or DIN 70070 standard.

  • You can securely store the DEF in your vehicle between temperatures of -11°C and 25°C.

  • Consult your vehicle’s handbook for instructions on how exactly to top-up.


You must contact your retailer if a problem is detected with your DEF quality or flow rate.

GLOSSARY AND FREQUENTLY ASKED QUESTIONS

What is NOx?
NOx is short for Nitrogen Oxides, which are chemical compounds formed from nitrogen and oxygen. Under high temperatures, such as those resulting from the combustion of fuel in air, nitrogen and oxygen undergo a series of chemical reactions, combining to form NOx.

What Is Diesel Particulate Matter?
Diesel Particulate Matter is a complex mixture of solid and liquid particles suspended in exhaust gases. These particles vary greatly in size, composition, and origin, but primarily consist of very small soot particles, generated during combustion.

How do manufacturers demonstrate compliance with the Euro emissions standards?
Vehicles are regularly tested in a laboratory in accordance with a set of industry-wide legally prescribed procedures in the presence of an independent authority. In addition, manufacturers also have an obligation to periodically test the performance and conformity of newly manufactured cars to ensure that vehicles demonstrate effective emissions control and perform as designed.

I’ve read that vehicles exceed the Euro emissions standards in the real-world. Why is this?
The current industry-wide laboratory testing procedures provide a highly repeatable and standardised approach to measuring the emissions performance of vehicles. However, in practice the conditions experienced in real-world driving – such as environmental conditions, traffic, road speeds and personal driving styles – can be much more variable and can influence the emissions performance of a vehicle.

The development of the test procedures has not maintained pace with advances in vehicle design and functionality. To address this situation, a new laboratory based test procedure is under development and laboratory testing will be supplemented with a Real-world Driving Emissions test (commonly abbreviated to RDE). The RDE test will require manufacturers to measure the emissions performance of vehicles under real-world conditions.

What are the health effects of diesel?
The science is still emerging and it is important to note that there are many sources of these pollutants such as particulates and NOx; diesel engines are only one of these. We are confident that the Jaguar vehicles we build today have dramatically reduced the level of emissions they produce. Yet air quality can only be consistently improved in partnership with industry, government, academics and consumers.

What is a Diesel Particulate Filter (DPF)?
All our diesel engines are fitted with a Diesel Particulate Filter (DPF). The DPF forms part of the emissions reduction system fitted to your vehicle. The DPF removes up to 99% of the carbon microspheres (soot) before they leave the exhaust. It does this by filtering out the particles, which are then stored until they are burnt away automatically and the filter is emptied.

I drive in an urban environment. Is this a problem with a diesel?
Driving in an urban environment is not a cause for concern. Unlike a normal filter, which requires periodic replacement, the DPF has been designed to regenerate, or clean itself, to maintain operating efficiency. This regeneration process takes place automatically while the vehicle is being driven. In some instances e.g. if the majority of your journeys are short or consist of slow speeds the system may not meet the required temperature to allow the DPF to regenerate. In this instance a yellow light will be lit on the driver’s instrument panel. If this occurs, a 20-minute drive at a constant minimum speed of 45mph will ensure the system regenerates.
