DIESEL TESTING
As part of the MOT test your vehicle will be checked for smoke emissions. This helps the environment by minimising pollution & testing the fuel efficiency of your vehicle. It also helps you by checking that the engine is working correctly & reduces wasted fuel.
HOW DIESEL EMISSION ARE TESTED
The test has been developed so that it should not damage your engine. The tester will check the maintenance history of your vehicle by asking you some questions. The tester can refuse to test your vehicle if he thinks that the smoke test will damage the engine.
TO REDUCE THE POSSIBILITY OF DAMAGE & INCREASE THE CHANCES OF YOUR VEHICLE PASSING YOU SHOULD
Keep your vehicle maintained at all times
Go to the test centre with a fully warmed up engine - it will produce less smoke & is safer to test.
Have the camshaft drive belt replaced at the recommended intervals
Do not tamper with the governor settings. They have been set to help ensure the engine runs efficiently.
THE TEST
After checking the oil temperature to ensure the engine is warm, the tester will accelerate the engine from idle until the governor cuts in at a maximum of 6 times. Your engine will not be held at full speed for any length of time. If your engine has been maintained, the test should not cause any damage to your engine.
