Vehicle Emissions: What are they and how are they measured under the new MOT Test?

As of May 20th 2018 the MOT test for vehicles in the UK changed – but what does that mean when it comes to emissions? Never fear, Trust My Garage is here with the answers!

What are emissions?

The Department for Transport (DfT) states that emissions are pollutants created by petrol, diesel and alternatively-fuelled engines. These pollutants are; carbon monoxide, oxides of nitrogen, un-burnt hydrocarbons and particulate matter. The levels of pollutants present in each vehicle can depend on vehicle technology and the state of maintenance of the vehicle – so older cars have a tendency to produce more emissions.

 

Why do emissions matter?

Like all pollutants, they cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, which has been cited as a cause of global warming, acid rain, environmental damage and human health damage. Engine noise and fuel spills also cause pollution. Nitrous oxide emissions have also been shown to contribute to the depletion of the Ozone layer around the Earth.

 

How is the new MOT test combatting emissions?

The MOT test now includes updates for the amount of emissions a diesel vehicle can produce – with garages also having to update their Diesel Smoke Meters to ensure they meet requirements for testing. Find out what the .Gov website states about emissions testing here.

 

As well as this, if your car is new enough to have a Diesel Particulate Filter (DPF), evidence that it has been tampered with – or the presence of exhaust smoke of any colour – will now constitute a ‘major’ MOT fault. This will need to be rectified before a pass can be issued.

What else is being done to help?

Over time, vehicle manufacturers have realised the importance of emissions and pollution for the environment. The ‘Euro 6’ emission standard has provided a benchmark form of legislation, and as of September 2015 all mass-produced cars sold from this date need to meet the set requirements. The aim of Euro 6 is to reduce levels of harmful car and van exhaust emissions, both in petrol and diesel cars.

 

Emissions of air quality pollutants from road vehicles have been reduced by improving the quality of fuels and by setting increasingly stringent emission limits for new vehicles. As an example, it would take 50 new cars to produce the same quantity of air quality pollutant emissions per kilometre as a vehicle made in 1970.

 

How can motorists help?

When you’re driving you may not think about the impact your vehicle could be having on the environment – but if you’re concerned about reducing the effects of pollution, there are some very simple tips to utilise:

Drive Steadily – hard acceleration and braking forces your vehicle to work harder, creating more emissions from your exhaust.

Don’t overload – the additional weight will require you to use extra power. This means that your engine is using more fuel to accommodate the extra kilos.

Have regular services – By keeping your vehicle well maintained you can ensure all its internal parts are working efficiently, putting less stress on your motor and the environment! Don’t forget, you can book a service and find your nearest Trust My Garage member here with our ‘Find a Garage’ map.

Stretch your legs – if you feel comfortable walking or cycling, then do so! Leaving your vehicle at home means it definitely can’t emit any pollutants.

Is your car ready for the school run test?

If you are a parent with a child under the age of 16, you may be feeling a little stressed right now. This time of year is difficult and expensive for parents preparing their children for the start of the new school term. There’s such a lot to think about; uniforms, equipment, textbooks, bags, new shoes – and that’s just for starters. The last thing you are going to need is for your car to breakdown on you during the infamous school run!

About one in five cars is driving a child or children to school in rush hour traffic and with the five million primary school children in the UK living on average of one and a half miles from their place of learning, it means there are a lot of cars on the road doing short journeys, five days a week. These driving conditions can cause much more wear and tear on your vehicle than you would imagine and no busy parent wants the stress or expense of a breakdown at this time of year.

Being aware of what causes damage to a vehicle can help reduce the risk of a breakdown or failure during the school run. Here are our top tips to shield you from unexpected repair costs as the kids go back to school.

schoolrunMake sure your engine is properly lubricated.

Most school runs are quite short journeys, which means that the engine on your vehicle does not have enough time to warm up properly. Engine oil has to reach its full operating temperature in order to lubricate properly This is more likely to be achieved over faster, longer journeys.

What’s the solution?                                        

Let your car ‘idle’ for a few minutes before you begin your journey and this will help your engine warm up ahead of your drive. It will also help to warm, your car up once the cold nights start to draw in. Remember though, don’t go back inside your house while your car warms up – it only takes a few seconds for a thief to take advantage of an empty vehicle.

Concentrate on reading the road.                                                 

Hurried braking causes greater wear on the brake pads, which will lead to more frequent trips to the garage.

What’s the solution?

Rather than stopping and starting in traffic, slow down and concentrate on reading the road. By driving more slowly and anticipating when you need to stop, especially around the school environment where young people are likely to be crossing the road, you will apply less pressure to your brakes and gears. This will also help you to save fuel.

Keep an eye on your engine warning and DPF lights

If you drive a diesel vehicle, your are more likely to find your vehicle suffering from engine management problems if you frequently go on short journeys in your car. This is because of the diesel particulate filter (DPF).

The DPF, which traps larger soot particles within the filter and allows smaller particles and gases to escape, can only operate efficiently once your vehicle is driven at 45mph for more than five minutes.

Stop/start driving and motoring at slow speeds means that the soot accumulates and the DPF cannot create sufficient heat to regenerate. Once the soot concentration reaches about 75%, it will need to be looked at by a professional to be regenerated. Don’t ignore the engine warning light if your diesel car is used mainly for short journeys!

What’s the solution?

Make sure you get your car to the nearest Trusted garage if your engine warning or DPF lights start flashing on your dashboard. This is an indication that there is something that needs attention and if ignored, could incur costly repair expenses. In fact, any warning light illuminated on your dashboard is a signal that your vehicle needs some expert attention.
