Definitions
- the present invention relates to a method of controlling a supercharged spark ignition internal combustion engine.
- Each tubing is equipped with at least one fuel injection means, such as an injector, to be able to introduce fuel into the tubing and thus obtain a fuel mixture at the outlet of this tubing.
- a fuel mixture is formed upstream of the combustion chamber in at least one duct to be able to meet the operating conditions of the engine. More specifically, at low load, one of the tubes is closed while the other remains open by injecting sufficient fuel to produce a homogeneous fuel mixture close to the richness 1 and this mixture is then introduced into the chamber. combustion. For average loads, the two pipes are open and one of the pipes is supplied with fuel to obtain a fuel mixture substantially richness 1 while the fuel does not feed the other tubing. This makes it possible to have a stratification between the fuel mixture with richness 1 and the non-carbide fluids (recirculated air and / or flue gases) introduced into the combustion chamber by the pipes.
- the two pipes are supplied with fuel so as to obtain a homogeneous mixture close to the richness 1 in the combustion chamber.
- the performance capabilities of the engine can not be used at their maximum and the mixture introduced into the combustion chamber does not limit the risk of rattling.
- the filling of the combustion chamber is poor considering that only a part of this chamber is occupied by a carburetted mixture.
- the fuel mixture introduced into the chamber is a homogeneous mixture with a richness close to 1.
- Such a richness is conducive to local autoinflammation (rattling) given the location of a part of the fuel mixture at a distance from the spark plug and consequently at a distance from the initiation of the ignition of this fuel mixture.
- the present invention proposes to overcome the drawbacks mentioned above by means of a control method of a combustion engine which makes it possible to use all the potential of the engine while avoiding creating zones in the combustion chamber favoring rattling. .
- the present invention relates to a method for controlling a supercharged spark ignition internal combustion engine, in particular of gasoline type, comprising at least one cylinder with a combustion chamber, at least two admission means, at least two a fuel injection means, at least one exhaust means and an ignition means, characterized in that: - a fuel mixture with a richness greater than or equal to 1 is produced,
- the two carbide mixtures are introduced into the combustion chamber so as to obtain a part of this chamber containing a carbureted mixture with the richness greater than or equal to 1 and the remaining part of the chamber containing the carbureted mixture with the richness less than 1 .
- the two carbide mixtures can be introduced simultaneously into the combustion chamber.
- the ignition means can be placed in the part of the chamber containing the fuel mixture with a content greater than or equal to 1.
- At least one of the carbide mixtures may be introduced with a gyration movement along a horizontal axis, referred to as a "tumble" movement.
- FIG. 1 schematically shows, seen from above, a cylinder of a motor using the method according to the invention and
- FIG. 2 is a partial sectional view along line 2-2 of the cylinder of FIG. 1.
- FIGS. 1 and 2 there is shown a supercharged internal combustion engine 10 with indirect injection of gasoline which comprises at least one cylinder 12 of longitudinal axis XX (FIG. 2).
- This cylinder comprises a combustion chamber 14 delimited by the top of a piston 16 subjected to a reciprocating movement, the side wall 18 of the cylinder and the surface 20 of a cylinder head 22 which usually close the cylinder.
- intake means each comprise a pipe 32, 34 carrying a means for closing the outlet of the pipe in the combustion chamber, such as a valve 36, 38.
- a fuel supply means such as an injector 40 and 42 preferably carried by each pipe, allows to introduce fuel into the pipe upstream of the inlet valve.
- the exhaust means each comprise an exhaust pipe 44 and 46 provided with an exhaust valve 48 and 50. As illustrated in the figures, the intake and exhaust means are arranged in such a way that an exhaust means is substantially facing an intake means being included in the same cylinder portion and more particularly in the same half-cylinder.
- each half-cylinder therefore contains an intake means and an exhaust means, respectively 24, 28 and 26, 30.
- the cylinder head also carries an ignition means 52, such as a spark plug, to ensure ignition of the fuel mixture present in the combustion chamber.
- ignition means 52 such as a spark plug
- At least the intake manifold 32 of the half-cylinder C1 has a direction such that it allows a gyration movement along a horizontal axis to the fuel mixture once the latter is introduced into the combustion chamber 14.
- This movement of gyration is a rotational movement of the fuel mixture in the extension of the intake manifold 32 and around an axis which is substantially perpendicular to the axis XX of the cylinder 12.
- the intake manifold 34 in the other half-cylinder C2 has a direction such that it also makes it possible to introduce the fuel mixture that it conveys with a rotational movement of "tumble" type.
- the exhaust valves 48 and 50 are conventionally closed.
- the intake valves 36 and 38 are open and an intake fluid, such as supercharged air or a mixture of supercharged air and recirculated flue gas (EGR), circulates in the intake pipes 32 and 34.
- EGR supercharged air or a mixture of supercharged air and recirculated flue gas
- the fuel injectors 40 and 42 are controlled so that the injector 40 introduces a quantity of fuel into the tubing 32 sufficient for the fuel mixture introduced into the combustion chamber to be a rich mixture or at least stoichiometry , that is to say with a richness greater than or equal to 1.
- the other injector 42 is controlled so that the introduction of fuel into the pipe allows to obtain a lean fuel mixture, that is to say with a richness less than 1, which is also introduced into the combustion chamber.
- the rich fuel mixture is located in the half-cylinder C1 which preferably carries the spark plug and combustion of the fuel mixture will occur more rapidly. The combustion will continue in the other half cylinder without the phenomenon of burning with knocking can occur.
- the lean fuel mixture can be introduced into the combustion chamber with a gyration movement, called "tumble" movement, in order to further accentuate the lamination of the carbide mixtures.
- tumble a gyration movement
- the present invention is not limited to the example described but encompasses all variants and all equivalents.
