MOT's - Assisting you along with your Car being Greener3408330
An MOT now tests diesel emissions in order to lower emissions, to view how efficient your motor vehicle is and be sure it's running at its full efficiency rate and that there aren't any faults using the engine. It will help you chop down your CO2 emissions and, in turn fuel costs. As you may know, fuel emissions are some of the major contributors to high numbers of pollution. Diesel fuel requires less refining than petrol and produces cleaner emissions than petrol when burnt; however, when the engine isn't working properly, the engine has got to work much harder, in turn using more energy. The more fuel wasted, greater CO2 is emitted from the car.
A good way to tackle wastage of fuel and increased CO2 emissions is actually testing should your engine is working correctly. This in an MOT is named the 'Smoke test', which tests the degree of emissions.
The Smoke Test:
Before you take a smoke test it is recommended that you continue your vehicle well kept, that you make sure the tail pipe is damage free, contain the camshaft drive belt replaced regularly and go into the MOT having a warmed up car, which has a decent level of fuel in. The tester when preparing may also look at your MOT past and decide accordingly if it's safe being tested you aren't.
To begin with an MOT tester will make certain the oil is heated up before completing test. After that is okay, he'll accelerate the engine from the idle position until the governor cuts in. A smoke meter will measure the degree of emissions, which is to be recorded. Your automobile will be tested for starters a maximum of three times, in the event the reading is unsatisfactory, he or she will then perform the test another three times. The Mot Bay Reading might create a general average, which will then let you know should your car is roadworthy you aren't.
The final results:
Should your car passes your safe to be on your way, however, if not clearly there should be something faulty with your engine, which must be repaired. The passing rate for the non-turbo charged engine is below 2.5m-1 3.0m-1 or under for turbocharged engines.
Even though you might pass this test, there might be some other because of not passing the emissions section in a MOT, including excessive smoke and vapour, discoloured emissions and strange noises. All of these suggest there is a fault using your engine or it's connected parts.
