Definitions

  • the object of the invention is to remedy this, and proposes to heat the window washing liquid using a heat exchanger by means of the air which is led to the air filter and heated by the outlet collector and to spray the liquid thus heated onto the window.
  • the heated windscreen washer fluid also effectively removes stubborn dirt.
  • the outlet collector is the collector pipe in which the hot combustion gases coming from the individual cylinders are collected, where high temperatures occur immediately after the engine is started.
  • the heat exchanger is switched on via the two pipe sections 4,4A in the preheating duct.
  • a coil 1A of good heat-conducting material, preferably copper, is inserted at 6 and 6A into the line for the windshield washer fluid. About 2 minutes after starting the engine, enough hot air flows through the heat exchanger to heat the windshield washer fluid passed through coil 1A so that the ice on the windshield can be removed.
  • the windscreen washer system consists of the pump 7 to be switched on via the switch TA, the reservoir 8 and the spray nozzles 6B.
  • the preheating flap 3 in front of the air filter 5 is actuated by a valve 3A controlled by a thermostat, this flap being fully open at the beginning and being closed successively as the temperature of the motor increases; this also regulates the temperature of the washing liquid reaching the pane in the desired sense.

Abstract

Pour dégivrer de façon efficace le pare-brise d'un véhicule, le liquide du lave-glace traverse un échangeur de chaleur (1) avant de parvenir aux buses de giclage (6B). Le liquide de lavage est conduit à travers un serpentin (1A) dans l'échangeur de chaleur. Afin de permettre un rapide chauffage du liquide de lavage dès le démarrage du moteur, l'échangeur de chaleur (1) est inséré dans le canal de préchauffage (4, 4A) entre le collecteur des gaz d'échappement (2) et le filtre à air (5).
