Decoding BMW Walnut Blasting: Cleaning Your Engine for Peak Performance
BMW is known for its more powerful engines and precision engineering, but even these engines require maintenance and cleaning to keep them operating to peak performance. To maintain BMW engines, we employ a cutting-edge process that cleans the engine and restores its original power. Quality Import Services in Elkhart IN uses walnut blasting to clean the inside of the engine of carbon buildup and oil.
What is Carbon Buildup?
Carbon deposits form due to the combustion process in the engine – where fuel and air mix, ignite by a spark and then burn. Throughout the combustion process, carbon particles from the fuel and oil adhere themselves to the engine’s pistons, intake valves and ports, and other parts. As the carbon deposits build up, they create a hard coating on the engine’s internal parts. Over time, carbon buildup causes many engine problems, including:
- Reduced efficiency as they restrict air flowing into the combustion chamber.
- Power loss occurs when carbon builds up on the intake valves and interrupts the smooth flow of fuel and air.
- Engine knock, or detonation, which could damage the engine’s internal workings.
- Increased emissions.
Why Carbon Builds Up in BMW Engines
Carbon builds up in all engines, but more so in any engine with direct injection, such as most BMW engines. Unlike traditional engines, which mix fuel and air before they reach the cylinder, allowing fuel to clean the valves, direct injection engines introduce fuel directly into the cylinder, bypassing this cleaning step.
Bosch introduced the direct injection technology in 1951, aiming to increase fuel efficiency by cooling the chambers with fuel. Direct injection also creates higher engine compression and increased efficiency, leading to more torque.
As a result of fuel being directly injected into the chambers, there is no fuel flowing past the intake valves to clean them of carbon buildup.
What is Walnut Blasting?
Using crushed walnut shells to clean the inside of an engine came from the aviation industry. Over time, automotive technicians started using the process because it is so effective in getting carbon buildup out of engines.
Walnut blasting works because of the abrasiveness of the walnut shells. They are very hard and have an angular shape when they are crushed, so they have the ability to scrape the carbon off the intake valves and ports without scratching and otherwise damaging the engine’s interior.
The shells are forced into the engine using high pressure. When they hit the carbon deposits, the shells force the deposits to dislodge and break up. While the auto technician blows the crushed walnut shells into the engine, they also use a vacuum to extract the shells and dislodged carbon particles, preventing them from contaminating the rest of the engine.
Benefits of Walnut Blasting at Quality Import Services in Elkhart, IN
Using walnut blasting to clean your BMW direct injection engine has several benefits, including:
- Restoration of Performance: You’ll notice a smoother idle, improved acceleration, and increased power once the carbon buildup has been cleaned from your BMW’s engine.
- Thorough Cleaning: Carbon deposits are hard and stubborn to remove. Walnut blasting effectively removes even the most stubborn, caked-on deposits.
- Precision: Walnut blasting is targeted so it doesn’t damage engine components.
- Non-Toxic and Environmentally Friendly: Since walnut shells are natural and biodegradable, this method is much preferred and works better than running chemicals through the engine.
Vehicles that benefit the most from walnut blasting include high-performance vehicles, as well as those with turbocharged and direct injection engines.
