Definitions

  • the present invention is concerned with the take to avoid a heating up of injection valves and therewith to prevent an evaporation of the fuel.
  • the underlying problems are solved according to the present invention in that the injection valve is secured at the internal combustion engine under interposition of a head-insulating bush or sleeve.
  • the head-insulating sleeve may exhibit only a small contact area with the part of the internal combustion engine at which it is secured.
  • the heat-insulating bush or sleeve can be advantageously so constructed that is has no contact whatsoever with the injection valve itself.
  • the bush or sleeve can consist in a simple manner of a polyamide of any conventional type possibly reinforced with glass fibers.
  • Another object of the present invention resides in an injection valve for an internal combustion engine, particularly for an internal combustion engine with electronic fuel injection, which greatly improves the starting behavior and idling of the engine even after long high engine loads and/or high outside temperatures.
  • Still a further object of the present invention resides in an injection valve for internal combustion engines which avoids an evaporation of the fuel within the injection valve.
  • Another object of the present invention resides in an injection valve for internal combustion engines, particularly with gasoline injection, which avoids by simple means entailing few expenditures all of the aforementioned shortcomings and effectively achieves all of the aforementioend aims.
  • FIG. is a partial cross-sectional view through an injection nozzle for an internal combustion engine wit gasoline fuel injection in accordance with the present invention.
  • reference numeral 1 designates therein the cylinder head of an internal combustion engine which is equipped with an electronically controlled gasoline injection system of known type.
  • An injection valve 3 of any conventional construction is arranged in the cylinder head 1 under interposition of a rubber ring 2.
  • the injection valve 3 is secured at the cylinder head 1 by interposition of cup-shaped sleeve or bush 5.
  • the sleeve 5 consists of a heat-insulating material, of any suitable known type, for example, of a conventional polyamide possibly reinforced with glass fibers, and it has only a small area as contact area with the cup-shaped cylinder head I.
  • the sleeve or bush 5 has no contact whatsoever with the injection valve 3.
  • the temperature threshold at which an evaporation of the fuel takes place on the inside of the injection valve 3 is exceeded.
  • This temperature threshold lies at approximately 90 to 100 Celsius.
  • An injection valve arrangement for an internal combustion engine comprising: an injection valve secured at the internal combustion engine, a heatinsulating sleeve means interposed between said injection valve and the engine, said heat-insulating sleeve means being provided with only a small area contacting that part of the internal combustion engine at which it is secured, an elastic ring means interposed between said injection valve and said heat insulating sleeve means, said heat-insulating sleeve means having no contact whatsoever with the injection valve.
  • An injection valve arrangement for an internal combustion engine comprising: an injection valve secured at the internal combustion engine, a heatinsulating sleeve means interposed between said injection valve and the engine, an elastic ring means interposed between said injection valve and said head insulating sleeve means, said heat-insulating sleeve means having no contact whatsoever with said injection valve.
  • An injection valve arrangement for an internal combustion engine having a cylinder head, the arrangebase portion.
