What the Colour of Smoke from Your Car’s Exhaust is Trying to Tell You

The exhaust system of a car has three primary responsibilities- manage the amount of fumes that the vehicle generates, reduce its noise and improve its fuel efficiency. It does so by employing many smaller components working in sync with each other within a network of pipes. In doing so, it withstands an astounding amount of heat and pressure as long as the car is turned on.

The exhaust system is one of the sturdiest parts of any car. It has a service life of over 50,000 miles which can extend up to 100,000 miles if one performs periodic maintenance. As important as the exhaust system is, its maintenance is often not part of an average car owner’s regular maintenance schedule. The results may be catastrophic both for your car as well as the environment.

A malfunctioning exhaust system increases the air and noise pollution emitted by a car like no other component. Take your car to Terry Elsey Tyres for inspection immediately if you notice that your exhaust is malfunctioning in any way. Along with fixing the exhaust, they’ll inspect and repair other essential parts of your car like the battery, tyre balance and Wheel Alignment in Malton.

Detecting Car Issues Based on Smoke Colour

When the tailpipe of your car starts belching out more smoke than it should, that’s a legitimate cause for concern. Not only is it bringing down the performance and fuel efficiency of your vehicle, but also causes environmental pollution. There are other consequences as well.

British road laws are particularly stern about vehicular emission, and if you are found driving in a car that’s emitting any visible smoke, you may be pulled over and fined. Furthermore, you won’t clear your MOT check with a faulty exhaust.

The colour of smoke coming out of the tailpipe may be a silent indicator of the underlying problem. If you notice the following colour of smoke from your car’s tailpipe, take it to a professional auto garage for an Exhaust Repair Malton immediately.

  • Blue Smoke

Blue smoke from the exhaust pipe indicates that there’s an oil leak inside the combustion chamber. It may be caused by a leaky valve, worn-out cylinder walls or piston rings. If you are burning oil in the combustion chamber, it’ll lead to slower acceleration, poorer mileage and drop in oil level which may further affect the performance of your engine.

  • Black Smoke

Black smoke indicates that the ratio of fuel in the air-fuel mixture is more than necessary. Gasoline engines require an optimum level of this mixture to perform adequately. More fuel in the mixture may be caused by malfunctioning injectors, a clogged air filter and/or fuel pressure regulator.

  • White Smoke

Normally, the exhaust system may produce trace amounts of clear or white smoke, which is nothing but water vapour and oxides of carbon. That’s nothing to be worried about. However, if the smoke is thick, it may be because the coolant has made way to the combustion chamber. Other possible explanations include blown out head gasket, overheated engine and cracked engine block.

Exhaust malfunction is not something to be taken lightly. Be responsible for the environment and perform exhaust maintenance and repairs regularly.
