Abstract

A microwave generator (1) feeds the energy to a diesel engine cylinder (4) through a conductor (2). The droplets of fuel (3) become agitated by oscillation of the molecules increasing the separation of the molecules and reducing the surface tension of the droplets, improving vaporisation and combustion of the fuel. The microwave activity may also be used to pre-heat the cylinder for cold-start conditions.

Description

1. Der Mikrowellengenerator (1) erzeugt Mikrowellen (5), die per Leiter (2) in den Zylinder (4) geleitet werden.1. The microwave generator ( 1 ) generates microwaves ( 5 ) which are conducted into the cylinder ( 4 ) by means of a conductor ( 2 ).

  • 2.1 Die Mikrowellen bringen die Molekülen des Kraft­ stoffes, das als Gemisch von Luft und Kraftstofftropfen (3) in dem Zylinder reingesogen werden, in Schwingung, und vergrößern damit den Abstand zwischen den Molekülen in den Tropfen. Die gegenseitige Vergrößerung der Entfernung zwischen den Kraftstoffmolekülen führt gleichzeitig zur Verminderung der gegenseitigen Anziehungskräften und der Oberflächenspannung der Tropfen und damit zur schnelleren Verdampfung.2.1 The microwaves vibrate the molecules of the fuel, which are sucked into the cylinder as a mixture of air and fuel drops ( 3 ), thereby increasing the distance between the molecules in the drops. The mutual increase in the distance between the fuel molecules simultaneously leads to a reduction in the mutual attractive forces and the surface tension of the drops and thus to faster evaporation.
  • 2.2 Außerdem treffen die Molekülen der Komponenten wegen der erhöhter Bewegung schneller aufeinander und verbessern zusätzlich das Verbrennen des Kraftstoffes.2.2 Also, the molecules hit the components because of the increased movement faster on each other and improve additionally the burning of the fuel.
  • 2.3 Die Schwingungen der Molekülen unter der Wirkung von Mikrowellen werden auch einen erhöhten Anstoß für die Braunische Bewegungen, die bei der Erhöhung der Temperatur während der Verbrennung ansteigen, geben,was bei allen gleichen den Druck unproportional erhöht.2.3 The vibrations of the molecules under the action of Microwaves are also a heightened impetus for that Brown movements that increase in temperature increase during the combustion, give what at all same increases the pressure disproportionately.
  • 3. Die Mikrowellen kann man auch für die Vorwärmung anstatt der Glühkerzen beim Kaltstarten der Dieselmotoren verwenden.3. The microwaves can also be used for preheating instead of glow plugs when cold starting diesel engines use.
