How Carbon Deposits Can Cause Performance Issues and Rob Your Car Fuel Mileage

If you own a car, you have probably heard people talking about how carbon build-up affects the health of your car. When buying a car, fuel efficiency is one of the most basic factors to consider. Most car manufacturers also use fuel efficiency as a selling point so this is something that no one can ignore. Now, let’s have a look at what carbon build-up means and its impact on your car engine.

Carbon build up refers to black soot deposits that form in the combustion chamber. Carbon build-up symptoms include: misfires, hard engine starts, black exhaust cloud that come out during hard acceleration, reduced acceleration, and rough cold idle. All these problems lead to decreased car performance. Below is a detailed description of the impacts of carbon build-up.

First, your car engine will lose its power. Carbon build-up changes the air to fuel ratio of the engine. Such a scenario occurs when sensors start functioning poorly due to carbon build-up that prevents the closure of the valve. This further makes the engine sluggish thus consuming more fuel.

Carbon build-up may occur in different places such as piston rings, head gasket, ports, pistons, and valves. Accumulation of carbon interferes with normal combustion in different ways. It may alter the compression ratio and the engine operating temperature among other factors involved in sensor readings and combustions. Carbon build-up leads to increased compression that further leads to overheating of the engine.

Carbon deposits significantly contribute to abnormal combustion. The most common dramatic effect in most cars today is the ‘sponge effect’. Compression of fuel mixture inside the cylinder causes the carbon to absorb fuel and oxygen. When the ignition sparks fires, flames may spread that end up consuming both the air and fuel. This combustion explains the high consumption rate of fuel.
