Definitions
- the invention relates to a new laboratory test intended to evaluate the tendency of a petrol, possibly additive, to make deposits during the operation of an engine.
- additives and additive formulations have been developed. These are generally polymeric surfactants comprising a lipophilic part ensuring solubility and a polar part capable of adsorbing on the walls of the engine in order to protect them or on insoluble particles in order to keep them in suspension.
- a carrier oil which can be a polyolefin or a polyether.
- the present invention proposes a new laboratory test intended to evaluate the tendency of a gasoline possibly additive to make deposits on the intake valves and in the combustion chambers.
- the method of the invention can be defined, in general, by the fact that a tube is placed in the oven of the injector of a gas chromatograph; said tube is kept at a constant temperature under a constant air flow regulated by the flow meter of the chromatograph; injecting the gasoline or the additive gasoline to be evaluated through said tube; and the quantity of deposits formed is determined by weighing said tube after dismantling.
- FIG. 1 schematically represents the apparatus used to carry out the test of the invention.
- FIG. 2 shows an arrangement of an oven with a chromatograph tube and a needle such that it can be used to carry out this test.
- the invention is described in more detail below, in conjunction with Figures 1 and 2.
- the numbers in parentheses refer to these figures.
- the tube (5) used consists of one (for example made of glass) of a gas chromatograph injector (1).
- the tube (5) is placed in the oven (4) of the injector. It is maintained at a constant temperature under a constant air flow regulated by the chromatograph flow meter (1).
- Petrol or additive petrol to be evaluated is injected through the tube (5), by means of a needle (6), most often positioned so that the injection takes place at a depth of approximately 10 mm inside the tube (5).
- the gasoline is injected via a pump (2) at a flow rate of 0.5 to 2 kg, preferably of the order of 1 kg per 24 hours.
- the mass injected is checked by weighing using the balance (3).
- the quantity of deposits formed is determined by weighing the tube (5) after dismantling.
- the laboratory test of the invention behaves like a test representative of the intake valves, whereas in the temperature range of 325 to 375 ° C and preferably to 350 ° C, said test is representative of the combustion chambers.
- the gasoline to be evaluated is, before injection, freed from 15 to 25% and preferably 20% by mass of its lighter fractions by sweeping an inert gas at room temperature. Indeed, it is generally accepted that only heavy fractions are responsible for the formation of deposits and such a procedure makes it possible to avoid degassing of the petrol at the level of the pump which would cause its defusing.
- the following examples illustrate the invention but should in no way be taken as limiting.
- a reference gasoline whose characteristics are grouped in Table 1 and from which 20% by mass has been eliminated by argon sweeping at room temperature is introduced by means of an alternating piston pump
- Hewlett-Packard 18740-80190® of a gas chromatograph by a needle positioned so that the injection takes place at a depth of 10 mm in the insert, the temperature of the injector being maintained at 275 ° C.
- the insert is removed and weighed. The mass of deposits obtained is 30.5 mg.
- Example 2 If in Example 1, all other things being equal, different quantities of a commercial detergent additive are added to the gasoline to be evaluated, the following results are obtained which are collated in Table 2. In this same table, appear the results of the Mercedes 102E engine tests (CEC procedure F-05-A-93) carried out with the same fuel samples and expressed in mass of deposits on the 4 intake valves.
