Diesel cars are blamed for poor air quality courtesy of their exhaust emissions

Diesel car sales are falling as drivers turn their back on it because of health concerns. But diesel power is about to hit back with new technology designed to reduce harmful exhaust emissions.

Official figures show that sales of diesel cars were down in the UK by a fifth in May 2017 and by 15 per cent in June. That’s compared with the same period in the previous year. The slump is believed to have been caused by various factors. The high-profile Volkswagen diesel cheat device case raised people’s awareness of the harm of the nitrogen oxide (NOx) pollutants diesel produces. But people are also concerned that diesel cars may be slapped with hefty taxes.

However, we can reveal that diesel is hitting back. Automotive technology giant Continental has worked out how to make a much cleaner diesel car.

Why do we need diesel?

AdBlue: What it is, how it works and why it’s vital for some diesels

Run out of AdBlue and you might struggle to get going again

AdBlue is becoming an important part of our motoring life. And for drivers of diesel cars it could make the difference between miles of trouble-free, low pollution motoring and their car not working at all.

There are currently estimated to be more than 200,000 vehicles using AdBlue in Europe. This is because it’s been popular in the haulage industry for the past 20 years as a means of reducing poisonous exhaust emissions.

Although AdBlue is neither a fuel nor a fuel additive, cars that use it can stop running if they don’t have a sufficient amount in a special on-board tank. That’s because the AdBlue is designed to be injected into the exhaust fumes and remove the harmful nitrogen oxide gases. The trouble is, some drivers aren’t sure what AdBlue is and ignore the car’s reminders to fill it up. Sometimes when the AdBlue tank runs dry the car won’t start and they then have to call us out to get going again. Here’s all you need to know about AdBlue.

How do you know if your car uses AdBlue?
