What is Car Engine Decarbonisation?

Engine Decarbonisation is a method of removing carbon deposits from a vehicle's engine, thus improving performance and fuel efficiency. Diesel engine decarbonisation uses unique treatments on parts like injectors and combustion chambers, increasing power output while minimising emissions.

Meanwhile, decarbonising petrol engines includes cleaning the intake valves and combustion chambers. These have carbon deposits and cause low power. For both processes, the decarbonising fluid plays an essential role. It dissolves stubborn deposits, allowing us to flush them out. Using such fluids keeps the engine clean, boosts fuel economy, and prolongs engine life.

Types of Car Engine Decarbonisation Procedures

Decarbonising a car engine involves removing carbon deposits that accumulate over time. The proper method depends on the engine type and the extent of the carbon buildup. Here's an overview of the most common techniques:

Method Description
Chemical Cleaning
  • The chemicals used in this method are special cleaning agents put into the engine. 
  • They are effective in the dissolution of persistent carbon deposits, restoring engine efficiency. 
  • It is a non-invasive way to do regular maintenance. It will increase efficiency.
Manual Cleaning
  • The engine is disassembled. Then, the high-pressure scrapers are used to remove carbon buildup.
  • It is the best choice for cleaning up heavily carbonised engines, but the work is tireless.
  • Mechanics may recommend it for old engines or engines with severe carbon buildup.
Ultrasonic Cleaning
  • This advanced technique utilises sound waves in combination with a cleaning solution.
  • This method is beneficial for tiny components which are too intricate to clean in the engine.
  • With this, the buildup in every nook and cranny will be completely removed from the engine. 

Common Issues Caused by Carbon Deposits in Engines

Car engines can experience carbon deposits with a range of operational issues. They can also negatively impact the performance and lifespan of the system. Here are the most common problems with the carbon build-up:

Low Fuel Economy

When carbon builds up in the fuel injector or intake valve, it affects the air-fuel ratio. Thus creating insufficient combustion. This causes a rise in fuel consumption, which, in turn, decreases the car's fuel efficiency.

Low Engine Power

The decrease in combustion processes happens due to more than a sufficient amount of carbon deposits. This leads to lower combustion, significantly restricting the engine's accelerating performance.

Higher Emission Rate

The incomplete combustion of fuel causes a higher carbon build-up, which might mean the vehicle emits more than the allowed emission control level. This may cause environmental pollution.

Engine Misfire

Deposits clog the spark plugs or intake valves, causing non-uniform ignition. When they trigger more than one ignition cycle, they may also cause stalling, which leads to the engine misfiring.

Mechanical Wear on Engine Components

Over time, carbon buildup can cause wear and tear on valves, cylinders, and even injectors. This makes repairs costly in the long run, increasing your out-of-pocket expenditure.

Key Benefits of Decarbonising Your Car Engine

Decarbonisation has many benefits for a car's engine. It increases both power and longevity. Below is the list of key benefits:

Enhanced fuel efficiency

The decarbonised engine will ensure clean fuel combustion inside it. Hence, there is no waste. It allows the vehicle to travel at the highest mileage per unit of fuel. Thereby reducing the spending on fuel.

Power Restoration

Removing the deposits that block airflow boosts fuel delivery. This improves throttle response and accelerates at a faster rate. In this way, the engine becomes stronger and responds faster.

Lower Emissions

It is only in a clean engine that fuel combustion occurs. Thus, the production of toxic fumes is lesser. Environmental pollution decreases cleaner emissions. This leads to a healthy, sustainable, and safer environment.

Less Maintenance Costs

Cleaning prevents significant problems in engines. This limits the probability of the occurrence of repair expenses. Regular cleaning prevents an engine from becoming unreliable.

Good Resale Value

Proper engine maintenance improves its performance and looks. It attracts more customers and increases resale value. A clean, efficient engine is a marketing tool. Thus, it helps in fetching you a reasonable price.

How is Engine Decarbonisation Performed?

Engine decarbonisation involves several steps depending on the chosen method. The process ensures the effective removal of carbon deposits without damaging the engine. Below is a step-by-step process of a typical decarbonisation :

Step 1

Inspection and Diagnosis

The technicians will begin the process of decarbonisation by inspecting the engine. This helps them assess the engine's performance and decide the carbon build-up level.

Step 2

Preparation

After diagnosing the fault, the professional cleans the engine from the outside. Sometimes, they disassemble the engine's components according to the preferred form.

Step 3

Application of Decarbonisation Method

Here comes the decision to choose the method. You can also get help from the technician for this. There are three primary methods when it comes to decarbonise the engine.

Step 4

Reassembling and Testing

Once they clean and fry out the engine, they will reassemble it into place. The technician will test its performance to ensure proper functionality.

Signs Your Car Engine May Need Decarbonisation

When an engine has too much carbon buildup, it shows signs. The signs would have helped avoid major problems and maintain good engine performance. Here are some signs that show it is time for your car's decarbonisation:

 

  • Sluggish Acceleration: If the engine responds slowly when you step on the gas, it's time to clean it. Carbon deposits may block air or clog injectors, compromising engine performance.
  • Rough Idle: An unbalanced or wobbly idle when the car is stationary. This indicates that carbon deposits are causing abnormal combustion. Moreover, any rough behaviour by the engine means the engine is inefficient.
  • Lower Miles per Gallon: Accumulation might disrupt regular combustion and burn more fuel. Thus, non-proper combustion achieves fewer miles per gallon. Therefore, there will be higher fuel expenses over the long haul.
  • Engine Misfire and Stalling: A stalled car has a carbon issue. The situation shows that the choked valves or spark plugs are causing the problem. This could mean fewer cycles in each ignition, or the car engine may be unreliable.
  • Increased Exhaust Smoke: Black smoke indicates improper fuel combustion in the engine. Carbon buildup contributes to these inefficiencies, which could even exacerbate the problem of increased emissions.
