Definitions

  • Thermostat is a mechanical piece and it gets opened as a result of heat which is caused by engine or due to heating resistor by MAP sensor and it does not include any controlling ability except for this state. Moreover, it shows resistance in the route of water flow (in the open mode), as a result of which further power and fuel will be consumed via water pump. On the other hand, regarding the lack of control on its function, if this segment works properly, serious damages will be caused to the vehicle.
  • Map control thermostat was produced containing an additional heat resistance and from then on, no change has been made on it.
  • the main objective of this invention is to redesign this segment to control engine temperature efficiently and as a result the engine will be in a better condition and greenhouse gases as well as fuel consumption will decrease.
  • the principal solution for the present problem is to redesign the thermostat and change its structure.
  • Thermostat segment is eliminated and is replaced by a butterfly valve which is opened and shut by an engine and controls the water flow toward the radiator (without exerting any resistance in the path and in an open mode) and the exact angle of valve is estimated every moment through a sensor.
  • the angle of valves is determined in a way that the engine temperature will remain stable as long as possible and consequently fuel consumption will reduce.
  • the thermostat functions based on an adaptable smart computer system and according to the considered function, it can adapt itself to the environmental conditions and variables. For instance, if it is used in an automobile, then it can adjust its function according to the environmental conditions and the driving manner and if it is used in air conditioning system, it can adjust itself with the new conditions in case the temperature changes.
  • Fig 1 the segments of thermostat.
  • thermostat body is connected to the engine block on one side and on the other side it is connected to a radiator by a pipe. This segment is used as the main part on which the other parts of thermostat are assembled.
  • Gear box frame 2 this part is the first piece of two-part holding frame of related gears and belts and it is used as the holding container of gears, belts and the sensors which are installed on the shaft valve.
  • Gear box frame 3 this part is considered as the second piece of holding frame of gears, belts and the sensors installed on the shaft valve and form a closed container to protect gears, belts and sensors.
  • this sensor is mounted on the valve shaft and it determines the angle for opening and closing the valve at every moment. This part is placed inside the gear container.
  • Gear on the engine axis 5 this gear is directly installed on the engine axis and it is responsible for transferring engine power through belt and gear to the shaft and also opening and closing the disk.
  • Gear on the valve shaft axis 6 this gear is directly installed on the shaft valve axis and it is responsible for transferring power from the engine to the shaft and to change the angle of disk blocking valve (opening and closing disk).
  • Disk blocking valve 7 this part is installed on the valve shaft by two pins and it rotates together with the shaft, opens and closes the thermostat valve and controls the flow of engine cooling liquid.
  • Shaft 8 this piece is placed in a hole and installed on the body of thermostat which exactly passes the determined path for the flow of automobile engine cooling liquid and the gears, sensor as well as the disk are mounted on it.
  • Pin connecting disk to shaft 9 there are two pins which are responsible for connecting blocking disks to the shaft valve.
  • Engine 10 this is an electric engine which provides the required power for closing and opening the valve and it is installed in a hole, on the thermostat body.
  • thermostat map control is activated only through the sensor map output (just for opening), but in the present invention, the control is done completely, and based on the conditions of each moment, the valve is precisely regulated to increase or decrease water flow by one or two degrees while predicting the conditions by using different parameters and output data of various sensors.
  • the piece is installed inside the automobile ECU and the program which is written for its function is saved into the ECU. Then the present segment replaces thermostat and the engine continues working without any change. However, to adjust the segment with the limited space inside the container of automobile engines, it is better to optimize the engine appearance or do minor model update.
  • This segment is applied in different kinds of automobiles and replaces the present thermostat.

Abstract

Le thermostat est une pièce mécanique qui s'ouvre sous l'effet de la chaleur produite par un moteur ou par un conducteur chauffant du capteur de cartographie, et il ne présente pas d'aptitude à la commande, sauf pour cet état. De plus, il présente une résistance sur le trajet du flux d'eau (en mode ouvert), ce qui résulte en une augmentation de la puissance et du carburant consommés par la pompe à eau. L'objet principal de la présente invention est de revoir la conception de ce dispositif pour commander efficacement la température du moteur, ce qui conduira à un meilleur état du moteur ainsi qu'à une réduction des gaz à effet de serre et de la consommation de carburant. La principale solution au problème présenté est de revoir la conception du thermostat et de modifier sa structure. Selon l'invention, le thermostat est éliminé et remplacé par un robinet à papillon qui est ouvert et fermé par un moteur et commande le flux d'eau vers le radiateur (sans exercer une résistance sur le trajet et en mode ouvert), l'angle exact du robinet étant estimé à chaque instant par un capteur.
