Definitions

  • the present invention relates to an installation according to Claim 1.
  • An installation of this type is disclosed in the publication:
  • Sequential injection is known for the injection of petrol in vehicle engines. This means that the cylinders are supplied with fuel in ignition sequence.
  • an installation of this type comprises a central rail to which one or more injection valves are connected for each cylinder, which injection valves are activated electrically. Said injection valves will be activated for only part of a revolution of the crankshaft.
  • the aim of the present invention is to employ a construction of this type in internal combustion engines which operate on gas, such as natural gas, hydrogen or LPG.
  • said opening corresponds with an opening adjoining the individual feed to each of the cylinders.
  • Metering takes place by moving the piston with respect to the stationary opening.
  • the passage is made V-shaped in order to provide accurate metering.
  • Positioning of the piston is effected by a stepping motor. Sequential injection is not proposed in this publication. Instead of a single Schlitz it is also possible to use a multiple Schlitz as disclosed in the prior art, which multiple Schlitz is likewise installed upstream of the distributor. Moreover, it is possible to install a number of Schlitz devices upstream or downstream of the distributor.
  • the Schlitz device as a shut-off valve, that is to say to install no further shut-off valve downstream of the latter. This means that during continuous operation said device gradually opens further or less far, depending on the operating status, and that the Schlitz makes a very rapid movement during starting or deceleration.
  • Fig. 1 shows, diagrammatically, a first embodiment of the invention
  • Fig. 2 shows a cross-section of the Schlitz device according to Fig. 1;
  • Fig. 3 shows, highly diagrammatically, a number of alternative embodiments with a "Monoschlitz" element;
  • Fig. 4 shows an alternative embodiment with a "Multischlitz" element.
  • FIG. 1 A first embodiment of the invention is shown diagrammatically in Fig. 1.
  • the installation shown here is suitable for operation both with petrol and with LPG and to this end a switch 11 is fitted.
  • the pressure in the inlet tract is measured via a MAP sensor 12, which is likewise connected to microprocessor 6.
  • the fuel supply comprises a feed line 13 for liquefied gas originating from, for example, a tank.
  • the liquefied gas is fed through shut-off valve 14 into vaporiser/pressure regulator 15.
  • the latter is equipped to dispense so-called dry gas, i.e. gas in vapour form, under a pressure of between 1.3 and 2.0 bar absolute into discharge line 16.
  • the pressure level is dependent on the load and is partly determined by the pressure prevailing within connection line 17.
  • Said gas in vapour form is fed through a dry gas shut-off valve 18, which is actuated by relay 19, which, in turn, is controlled by microprocessor 6.
  • the gas is fed into a distributor unit 20 where gas is, on the one hand, uniformly distributed over the individual lines 21-24 for the individual cylinders and, on the other hand, is metered.
  • An installation of this type is known as a Schlitz element. The functioning of this element is described in the International Patent Application 92/11448. This installation is shown in cross-section in Fig. 2. It can be seen from this figure that a plunger 25 can be moved upwards and downwards by the action of a stepping motor 26, as a result of which movement opening 27 is exposed to a greater or lesser extent.
  • shut-off valves 28-31 are installed in the lines 21-24. Said shut-off valves are connected via lines to a control 32, which, in turn, is connected to microprocessor 6.
  • Control 32 works in conjunction with microprocessor 6 or is integrated therein and in this way a system is obtained with which, at the point in time when, for example, the gas supply has to be terminated, as in the case of deceleration, where the throttle valve is closed and the engine has appreciable revs, the termination signal for the metering of fuel is not given immediately to all cylinders but is given in such a way that no new metering cycle of gas to a new cylinder is started but, on the other hand, the metering cycle for gas which is already in progress is completed.
  • Fig. 3 shows embodiments having a metering element or Schlitz device with a single in- and outlet. The latter is indicated by 33.
  • Said metering element can be any metering element known in the prior art which is able accurately to control the quantity of gas supplied.
  • a number of individual shut-off valves 36 corresponding to the number of cylinders are arranged downstream of the Schlitz element.
  • a multiple Schlitz is used, downstream of which a number of shut-off valves are installed.
  • the sequence is precisely the reverse.
  • Fig 4 the construction according to Fig. 1 is shown diagrammatically.
  • the installation according to the present invention is preferably driven in such a way that during the major part of the operation fluctuating loads are compensated for with the aid of the Schlitz device.
  • the shut-off valves are subjected to appreciably less wear.
  • the effect of sequential injection during continuous operation of conventional internal combustion engines which are driven by a gas is barely measurable if the composition of the exhaust gas is taken as the reference.

Abstract

La présente invention concerne une installation alimentant un moteur à combustion interne à plusieurs cylindres en un courant de gaz sous forme de vapeur. Cette alimentation se fait, d'une part, grâce au montage d'un organe distributeur (20) dans lequel l'alimentation commune en gaz (16) sous forme de vapeur est divisée et répartie entre tous les cylindres et, d'autre part, au moyen d'une soupape d'arrêt (28-31) montée dans la conduite de liaison (21-24) entre l'organe distributeur (20) et l'admission (3) du moteur à combustion interne. Cela permet la commande séquentielle du courant de gaz d'admission, de telle façon que, à l'instant où un signal de fermeture ou d'ouverture est reçu, l'alimentation en gaz, ou son interruption, pour le cylindre qui est en train d'être alimenté, se poursuit, et l'alimentation est arrêtée ou reprise, selon le cas, seulement au début de l'étape d'alimentation du cylindre suivant.
