Definitions

  • the present invention relates to an expansion tank according to the preamble of claim 1.
  • the amount of air which can be supplied to a supercharged combustion engine depends on the pressure of the air but also on the temperature of the air. Supplying as large an amount of air to the combustion engine as possible entails effective cooling of the air before it is led to the combustion engine. Effective cooling of the charge air may be achieved by subjecting it to two steps of cooling.
  • the charge air may be subjected to a first step of cooling in a first charge air cooler by coolant from the combustion engine's cooling system. This first step may cool the charge air to a temperature close to the temperature of the coolant.
  • the charge air may thereafter be subjected to a second step of cooling in a second charge air cooler by coolant from a low-temperature cooling system.
  • the charge air may thus be cooled to a temperature close to the temperature of the surroundings.
  • EGR exhaust gas recirculation
  • Cooling of charge air and recirculating exhaust gases in two stages as above entails using two separate cooling systems.
  • the coolants in the respective cooling systems are of the same kind but have different working temperatures during operation. It is therefore not appropriate for the coolants to be mixed.
  • the coolants become warmer during operation in the respective cooling systems, which means that they assume a larger volume.
  • each cooling system has its own expansion tank. On the occasion of servicing, the coolant levels in the respective expansion tanks in the cooling systems are checked and replenished as necessary.
  • the object of the present invention is to provide an expansion tank which can be used for servicing and liquid replenishment of two separate systems.
  • the expansion tank comprises two expansion chambers which are used for receiving coolant in two separate systems.
  • the expansion tank comprises a passage with an inlet aperture for liquid replenishment of the respective expansion chambers.
  • the passage has with advantage a slope downwards from the inlet aperture so that the liquid runs through the passage by force of gravity.
  • the liquid runs initially through a common portion of the passage.
  • the passage divides into a first branch which leads liquid to the first expansion chamber and a second branch which leads liquid to the second expansion chamber.
  • the expansion tank comprises a wall element which constitutes a dividing wall between the first expansion chamber and the second expansion chamber.
  • a dividing wall effects a simple and functional division of the space existing in the expansion tank into a first expansion chamber and a second expansion chamber.
  • the expansion tank may comprise a wall portion which protrudes into the passage so that the first branch is formed on one side of the wall portion and the second branch is formed on an opposite side of the wall portion.
  • the passage takes the form of, for example, a filling pipe
  • simple branching of the passage is achieved by a suitably shaped such wall portion which protrudes in at a lower end of the filling pipe.
  • the filling pipe has here an extent from an upper end at the inlet aperture to the lower end.
  • the wall portion which divides the passage into the first branch and the second branch constitutes part of said wall element.
  • the wall element which constitutes a dividing wall between the expansion chambers may here have a suitably shaped upper portion which extends into the filling pipe. Branching of the passage is thus achieved in an uncomplicated manner.
  • the passage divides into the first branch and the second branch at a height level which corresponds to a maximum level for the liquid in the first expansion chamber and a maximum level for the liquid in the second expansion chamber.
  • the cover comprises a closure element adapted to closing the first branch and/or the second branch when the cover is in the fitted state.
  • the closure element may comprise a contact surface adapted to coming into contact with at least a contact surface which defines an inlet aperture to the first branch and/or a contact surface which defines an inlet aperture to the second branch when the cover is in the fitted state.
  • the expansion tank comprises with advantage at least one seal element which defines at least one of said contact surfaces.
  • a seal element may be made of an elastic material, e.g. a rubber material. Very reliable closing of the first branch and/or the second branch may thus be achieved.
  • the closure element is adapted to closing the first branch and/or the second branch with a flexible force. It is possible to use for the purpose a spring means applied in such a way that it presses the closure element against a contact surface with a spring force when the cover is in the fitted state. If the pressure in either of the expansion chambers rises to a level above a highest acceptable value, the closure element may lift against the action of the spring means so that the pressure within the expansion chamber is reduced. When the pressure in the expansion chamber is reduced to an acceptable level, the spring means will reclose the closure element.
  • the liquid is a coolant intended to circulate in two separate cooling systems in which the coolants in the respective cooling systems are intended to be at different working temperatures during operation.
  • One cooling system may be a cooling system which cools a combustion engine and the other cooling system may be a low-temperature cooling system in which the coolant will have a significantly lower working temperature than the coolant in the combustion engine's cooling system.

  • the return line 11 comprises an EGR valve 12 by which the exhaust flow in the return line 11 can be controlled
  • a control unit 13 is adapted to controlling the EGR valve 12 on the basis of information about the current operating state of the diesel engine 2
  • the return line 11 composes a first EGR cooler 14 for subjecting the exhaust gases to a first step of cooling
  • the exhaust gases are cooled in the first EGR cooler 14 by coolant from the combustion engine's cooling system A.
