Abstract: PCT No. PCT/NL93/00222 Sec. 371 Date May 2, 1995 Sec. 102(e) Date May 2, 1995 PCT Filed Oct. 29, 1993 PCT Pub. No. WO94/10540 PCT Pub. Date May 11, 1995The flow rate of a medium flowing through a channel is measured by using a number of measurement sites along which the medium flows continuously at different velocities. The heating of the medium at the measurement site and the measurements of the temperature changes at the measurement sites are used to measure the rate of flow. Calibration information for the flow measurement for each measurement site is utilized to establish a rule which would include information about the measurement accuracy over the measurement range for each measurement site. The flow rate to be measured is established upon the basis of the measurement result of a measurement site which gives the greatest measurement accuracy according to the predetermined rule. The measurement of the flow at a measurement site comprises heating the medium during a first interval and during a second interval subsequent to the firest interval the temperature reduction is monitored at the measurement site. The flow rate is established on the basis of the temperature reduction.

Abstract: Cette invention concerne un système d'injection de carburant pour moteur à combustion interne de petites machines utilitaires. Le moteur comprend un bloc-cylindre dans lequel est monté à tourillon un vilebrequin dont le volant d'inertie porte un aimant sur son pourtour. Le vilebrequin est raccordé à un piston alternatif disposé dans le cylindre du bloc-cylindre. Une culasse montée sur le bloc-cylindre au-dessus du cylindre comporte un injecteur de carburant relié à un réservoir d'alimentation. Une bobine d'induction est disposée à côté du volant d'inertie et raccordée à l'injecteur pour qu'elle envoie à celui-ci un courant haute tension de commande à chaque tour dudit volant. Une pompe de carburant animée par le vilebrequin alimente l'injecteur en carburant sous pression. Un circuit de distribution raccordé à l'injecteur et à la bobine d'induction règle le fonctionnement du premier. Ce circuit neutralise la bobine d'induction au moyen d'un signal modulé en durée lorsque l'impulsion haute tension empiète sur le temps de fermeture théorique de l'injecteur. Un capteur de pression monté dans la culasse contribue à régler le fonctionnement du circuit de distribution.
