    摘要: A method and apparatus are provided for introducing a main fuel (12) and a pilot fuel (14) which is more readily flammable than the main fuel and which serves to ignite the main fuel into an internal combustion engine (10) having at least one cylinder having a combustion chamber. A set of conditions are defined to constitute high load conditions on the engine and to constitute low load conditions on the engine. The load conditions are detected. At high load conditions, the main fuel is introduced into the combustion chamber prior to introducing the pilot fuel and the pilot fuel is introduced into the combustion chamber a predetermined amount of time after the introduction of the main fuel. At low load conditions the pilot fuel is introduced into the combustion chamber in advance of the main fuel, and the main fuel is introduced into the combustion chamber a predetermined amount of time after the introduction of the pilot fuel.

    摘要: Device for the injection in internal combustion engines of combustible emulsions with a readily variable ratio, constituted by a hydrocarbon phase and a component poorly miscible with it, which comprises a positive-­displacement pump (10) driven by a portion of the delivery of the injection pump (1) fed with the hydrocarbon phase, said positive-displacement pump (10) carrying out the pumping of the other component of the emulsion; the two components of the emulsion are combined (9), (12) in the injector (8), which incorporates a static emulsifying device upstream the same injector.

    摘要: An improved injection system for a dual-fuel Diesel engine operated by means of main fuel having a low cetane number and auxiliary fuel having a high cetane number, is disclosed herein. The improvements reside in that the injection system comprises a pressure regulating check valve (7) provided in parallel to a delivery valve (6) in a main fuel injection pump (3) and allowing only a fuel flow in the opposite direction to that in the delivery valve, a control valve (16) for feeding the auxiliary fuel pressurized by a fuel feed pump (18) to a fuel injection valve (9) at an appro­priate feed rate and at appropriate fuel feed timing with the aid of a control device (20), and a check valve (13) provided in the proximity of a fuel reservoir (12) of the fuel injection valve (9) in a flow passageway of the auxiliary fuel.

    摘要: Le moyen consommant du combustible est alimenté en excès par une réservoir commun (11) lui-même alimenté en combustibles léger et lourd prélevés chacun dans leur propre citerne (5, 6) par une des canalisations (7, 8) dans chacune desquelles le débit n'est contrôlé que par l'une des vannes (9, 10) qui ensemble ne fournissent au réservoir que l'équivalent du volume du combustible effectivement consomme.
    Ce n'est qu'en sortie de ce réservoir (11) que dans une canalisation (14) rejoignant le moyen consommant le combustible, la circulation de ce combustible est assurée par une pompe (15) qui, contrairement à celui des deux vannes réunies, a un débit supérieur au volume de combustible consommé.
    L'excédent de débit est reconduit au réservoir commun. Application aux moteurs thermiques.
