Nutating intake systems:
An innovative approach to optimising engine performance
The intake system is a strategic component of an internal combustion engine, responsible for the precise supply of the right amount of air into the combustion chamber, which directly translates into optimum performance of the drive unit. Unfortunately, as a result of use, contaminants build up on the internal surfaces of the intake system. The solution to this problem is peanutblasting - an advanced cleaning technology for intake systems that effectively removes carbon build-up and other deposits, while guaranteeing complete safety for the system's delicate components.
Contaminated intake systems
- the invisible enemy of your engine
Over time, contaminants such as carbon deposits, soot and oil residues build up in the intake system. The problem particularly affects modern engines with exhaust gas recirculation (EGR) and direct injection. These contaminants can lead to serious problems such as:
- Decreased engine power and rough running.
- Increased fuel consumption.
- Problems with the turbocharger and EGR valves.
- Difficulty starting the engine and the ‘check engine’ light on the dashboard.
Can this be remedied?
Many motorists are looking for solutions to restore their intake system to full working order. Unfortunately, traditional cleaning methods are time-consuming, require the disassembly of many components and can be costly. In addition, the use of chemical cleaning products is not always effective and can be hazardous to delicate engine components. This is why the innovative peanut method is gaining in popularity.

Peanut cleaning - precision cleaning of intake systems
Walnut blasting, also known as walnut blasting, is an advanced method of cleaning intake systems that uses ground walnut shells as the cleaning medium. The process involves introducing the pellets under high pressure into the intake system, where the shell particles effectively remove carbon build-up and other deposits, while maintaining the integrity of delicate metal surfaces.
Key benefits of peeling technology:
- Efficiency: Innovative technology enables precise removal of carbon build-up even from hard-to-reach areas such as intake valves and flow channels.
- Safety: Walnut shell pellets are sufficiently soft to avoid damage to metal surfaces or seals.
- Ecology: The process is completely ecological – no aggressive chemicals or harmful waste generation.
- Minimal disassembly: Cleaning of the intake system is carried out without taking the engine apart, reducing service time and operating costs.

Benefits of regular cleaning of the intake system
Regular cleaning of the intake system is an investment in the long-term performance and reliability of the engine. It carries with it benefits such as:
- Improved engine performance: With a clean intake system, the engine runs at full power, resulting in better performance and a smoother ride. Optimised airflow allows for efficient combustion of the fuel mixture, which increases the dynamics of the drive unit, especially under demanding conditions.
- Lower fuel consumption: Efficient combustion of the fuel-air mixture, achieved through a clean intake, reduces fuel consumption in daily operation. In the long term, this not only means financial savings, but also a smaller carbon footprint, which fits in with modern environmental standards.
- Longer life of the turbocharger and EGR valves: A clean intake system minimises deposits on the turbocharger and in the EGR valves, which are key to the proper functioning of the engine. Fewer deposits reduce the risk of mechanical and chemical overloads, significantly extending the life of these costly components.
- Reduced risk of faults: Regular maintenance of the intake system prevents the build-up of deposits, which can lead to serious malfunctions such as blocked swirl flaps or damage to the injection system. This avoids unexpected repair costs and longer service downtimes for the vehicle owner.
Consequences of ignoring the problem
Ignoring the problem of a dirty intake system can lead to serious consequences:
- Shortened engine life: Contamination adversely affects its operation, which can lead to premature wear.
- More expensive repairs: A neglected intake system often leads to damage to the turbocharger, EGR valves or even the entire engine.
- Reduced driving comfort: Decreased power and increased fuel consumption directly affect the quality of use of the vehicle.
Peening is an effective and safe way to restore the efficiency of the intake system. With this method, drivers can enjoy better performance, lower running costs and longer engine life.
