Mercedes are highly-recognized cars that provide drivers with a sophisticated drive and a comfortable ride. Mercedes, as a brand, is committed to the future of diesel cars and continues to lead in innovation regarding cleaner engines, and this includes ensuring the combustion process is performed properly.
Any reaction that requires burning something is a combustion reaction. Most of the exhaust from your Mercedes comes from chemical combinations of fuel and oxygen. Combustion systems are used to generate power, but thermal energy is released when fuel burns in combustion reactions. If combustion is off, your engine’s timing will suffer, bringing down its performance. Exhaust emissions will also be toxic.
Symptoms of Improper Combustion in Your Engine
- Popping sounds from the engine: When an engine is running rich, it has too much fuel and too little air, which slows down the combustion process. The exhaust pump might not be bad but it doesn’t indicate anything good. Fuel igniting in the exhaust can cause popping sounds from the engine. This can cause damage to your vehicle either slowly or quickly. Sometimes, if you hear popping sounds from your engine, your car is probably telling you that it needs to be serviced. A clogged fuel filter can also cause popping sounds.
- Increase in fuel consumption: Combustion efficiency is comparable to crumbled coal-fired systems. It is affected by the fuel type and increases with volatile fuel matter content. Combustion efficiency increases with increasing excess air level and then decreases. Fast driving, quick acceleration but stopping your vehicle suddenly, only to accelerate again are the most common actions that lead to high fuel consumption.
- Increase in emissions: Usually your exhaust and catalytic converter work together to limit the number of harmful gases your engine produces. However, it can be less effective when your exhaust is old, damaged, or worn out. An increase in emission can cause the engine to deteriorate. It can also be detected through smoke testing under high-duty diesel inspection and maintenance.
- Difficulty in the engine: Failing fuel pump or bad fuel pump can affect the gasoline between your tank and engine. Also failed alternator and dirty fuel injectors. Your fuel system may cause improper combustion in your Mercedes noticeable when driving your vehicle at a low speed. If enough fuel is not passed to the cylinder, it can be caused by a misfire. Oxygen heavy explosions can occur when there isn’t enough fuel-to-air ratio. On some occasions, it can be as a result of bad gas in your Mercedes.
Reasons For Improper Combustion In Mercedes
The result of incomplete combustion is a misfire due to insufficient fuel entering into the cylinder. On rare occasions, you can have bad gas in your Mercedes, as there are several parts that regulate the amount of fuel that enters the cylinder. An engine misfire is a common issue in Mercedes vehicles that are lacking maintenance and replacement of wear items.
Under normal operation, the fuel and air mixture in the combustion chamber of your Mercedes engine ignites, but when it doesn’t get ignited at the precise time, it does not provide any power to turn the engine. This is detected by the engine control unit and causes the engine to misfire.
There are different problems of improper combustion which are ignition problems, problems with the air and fuel delivery, sensor and module problems, engine mechanical problems.

When the supply of air or oxygen is poor, incomplete combustion occurs. Carbon monoxide is produced 
during incomplete combustion as part of the carbon is not completely oxidized. Whenever a combustion reaction occurs without an adequate supply of energy, it is incomplete combustion. Unlike complete combustion, incomplete combustion produces less energy and carbon monoxide which is a poisonous gas.
Generally, heat, oxygen, and fuel are the three things required before combustion can take place. Mercedes is all about quality, comfortability, and luxury, so if your Mercedes is experiencing symptoms of improper combustion, visit us at Turning Wrenches to get your vehicle serviced.
