What You'll Learn
Black smoke from the exhaust
Black smoke coming from the exhaust is an indicator that the engine is running excessively rich, or using too much fuel. When the carburetor fails and delivers too much petrol or diesel to the engine, you’ll notice dark smoke. A faulty regulator can increase pressure in the system and your car’s fuel economy will suffer greatly. In some cases, the excess fuel will burn as black smoke.
The carburetor is the main component responsible for metering and delivering the air-fuel mixture required for the engine to run. So if it develops any sort of issue, it can throw off this mixture and affect engine performance. A bad carburetor may result in an engine with sluggish acceleration, and a noticeable reduction in power and fuel efficiency.
Fuel injectors control the amount of fuel delivered to the combustion chamber. When the parts go bad, you might notice your car shakes when the engine is idle. If the injectors deliver too much fuel, the excess will often burn as black smoke. It could be a sign that the parts need to be replaced.
Black smoke leaving your engine is often a sign that too much fuel is being burned. It could also be caused by a clogged air filter. If you catch either fault early, they are usually easy to fix.

Sluggish acceleration
Black smoke leaving your engine is often a sign that too much fuel is being burned. It could also be caused by a clogged air filter. If you catch either fault early, they are usually easy to fix.
Fuel injectors deliver petrol or diesel into the engine as a high-pressure mist. They can become clogged up with dirt or low-quality fuel, or leak because of wear and tear to the seals. Both the seals and injector itself can be replaced by a qualified mechanic.
A faulty regulator can increase pressure in the system and your car’s fuel economy will suffer greatly. In some cases, the excess fuel will burn as black smoke.
A bad carburetor may result in an engine with sluggish acceleration, and a noticeable reduction in power and fuel efficiency. The carburetor is the main component responsible for metering and delivering the air fuel mixture required for the engine to run. So if it develops any sort of issue, it can throw off this mixture and affect engine performance.
Older cars use a carburettor to mix air and fuel. When the part fails and delivers too much petrol or diesel to the engine you’ll notice dark smoke. It’s important to get the problem checked as soon as possible by a professional, as your car will be burning too much fuel and therefore producing excessive emissions.
