- the other additives different from the copolymer according to the invention chosen from the other known detergent additives, for example from anti-corrosion agents, dispersants, demulsifiers, anti-foaming agents, biocides, re
- a method of keeping clean (keep-clean) and / or cleaning (clean-up) of at least one of the internal parts of an internal combustion engine comprises at least the following steps :
- the internal combustion engine is a spark ignition engine, preferably direct injection (DISI).
- DISI direct injection
- the inner part kept clean and / or cleaned of the spark ignition engine is preferably selected from the engine intake system, in particular the intake valves (IVD), the combustion chamber (CCD or TCD) and the fuel injection system, in particular the injectors of an indirect injection system (IFP) or the injectors of a direct injection system (DISI).
- the engine intake system in particular the intake valves (IVD), the combustion chamber (CCD or TCD) and the fuel injection system, in particular the injectors of an indirect injection system (IFP) or the injectors of a direct injection system (DISI).
- the internal combustion engine is a diesel engine, preferably a direct injection diesel engine, in particular a diesel engine with Common Rail injection systems (IDRC).
- a direct injection diesel engine in particular a diesel engine with Common Rail injection systems (IDRC).
- IDRC Common Rail injection systems
- the internal part kept clean (keep-clean) and / or cleaned (clean-up) of the diesel engine is preferably the injection system of the diesel engine, preferably an external part of an injector of said injection system for example the nose of the injector and / or one of the internal parts of an injector of said injection system, for example the surface of an injector needle.
- the keep-clean and / or clean-up process advantageously comprises the successive steps of:
- the copolymer or copolymers can be incorporated in the fuel, alone or in mixture, successively or simultaneously. Alternatively, the copolymer (s) may be used in the form of a concentrate or an additive concentrate as described above.
- Step a) is carried out according to any known method and is common practice in the field of additive fuel. This step involves defining at least one representative characteristic of the detergency properties of the fuel composition.
- the representative characteristic of the fuel's detergency properties will depend on the type of internal combustion engine, for example diesel or gasoline, the direct or indirect injection system and the location in the engine of the targeted deposits for cleaning and / or maintenance. cleanliness.
- the characteristic characteristic of the fuel detergency properties may, for example, correspond to the power loss due to the formation of the deposits in the injectors or the restriction of the fuel flow emitted by the injector at the fuel injector. during the operation of said engine.
- the representative characteristic of the detergency properties may also correspond to the appearance of lacquering deposits at the injector needle (IDID).
- the amount of copolymer may also vary depending on the nature and origin of the fuel, particularly depending on the level of n-alkyl, iso-alkyl or n-alkenyl substituted compounds. Thus, the nature and origin of the fuel may also be a factor to consider for step a).
- the keep-clean and / or clean-up method may also include an additional step after step b) of checking the target reached and / or adjusting the rate of additivation with the copolymer (s) as a detergent additive.
- the copolymers according to the invention have remarkable properties as a detergent additive in a liquid fuel, in particular in a diesel or gasoline fuel, in particular block copolymers.
- the copolymers according to the invention, in particular the block copolymers according to the invention are particularly remarkable especially because they are effective as a detergent additive for a wide range of liquid fuel and / or for one or more types of motorization and / or or against one or more types of deposits that form in the internal parts of the internal combustion engines.
