Older petrol engines relied on fuel injectors to spray fuel into the air intake manifold where the air and fuel would mix. This mixture then moved through the engine cylinders at timed intervals and to the spark plugs where it ignited and boomed. It was a highly inefficient process that resulted in poor mileage and wasted fuel. However, due to the fuel injectors normally sit on top of the valves, they don’t get the carbon deposit build up that often because the valves get washed by injectors, means they don’t need the carbon clean service as much as the newer ones.
So why the late model engines need carbon clean service often? Newer vehicles have direct injection engines. In these engines the fuel is transferred directly to the combustion chamber, skipping the air intake manifold and cylinder changes. This process creates a ‘lean’ mixture of fuel and air,The leaner mixture of fuel/air to burns better and more efficiently. The combustion chamber uses higher levels of heat than in a traditional gasoline engine, so it burns fuel better, so you get more mileage per gallon and reduced fuel emissions.


- Petrol engines – Advanced Mobile Mechanics offer carbon clean service on petrol & diesel engines. But how does it happen? Carbon buildup occurs as the fuel burns in your car. Just like a log burning in a fire deposits soot and grime on the inside of a chimney, carbon deposits will begin to form in your new engine. This problem occurs mainly in more modern cars with engines from 2012 to the present. Why is this happening? Aren’t these cars supposed to last longer? The reason carbon build-up is occurring is a new engine technology, referred to as direct-injection technology. At Advanced mobile AutoCare, our mobiles can do a carbon clean service at your place or at work to ensure that your engine stays healthy at all time.The carbon build-up problem occurs because of the high efficiency of the direct injection engine. High combustion pressure in a direct injection engine causes the build-up on intake values and other parts of the engine. The fuel and the detergents in it bypass the valve and don’t clean it off like in a traditional gas engine which compounds the problem.
- Diesel Engines – Carbon deposit buildup on diesel engine components such as piston heads, fuel injectors and intake valves is a bigger problem than it is for petrol engines. There is a federal requirement that certain detergents be added to gasoline at the refinery itself, but there is no such mandate for adding detergents to diesel fuel. For this and many other reasons, diesel engines are more susceptible to carbon deposit buildup.Most of the blame, however, has been assigned to the fact that the fuel spray from a diesel injector goes directly into the cylinder bypassing, for example, the back of the intake valve where deposits are likely to form. The increasing use of high pressure common rail fuel systems have also increased engine deposits. Other reasons for diesel engine carbon deposits are the use of low-quality fuel, short cold weather trips, excessive idling, infrequent oil changes and even dirty air filters.Once carbon buildup begins to accumulate on various surfaces inside the engine and is left untreated, the vehicle loses power, becomes sluggish and causes a significant increase in emissions and reduction in fuel economy.
