Definitions

  • the invention relates to a method for regulating the heat balance of an internal combustion engine for a vehicle with a fluid circuit provided as a coolant circuit and controllable means for influencing the heat balance of the internal combustion engine, wherein a fluid temperature and further operating parameters of the internal combustion engine detected and the controllable devices in dependence of the fluid temperature and the other Operating parameters of the internal combustion engine are controlled.
  • a method of the type mentioned is from the document DE 102 28 355 A1 known.
  • a fluid temperature and other operating parameters of the internal combustion engine are detected and the controllable devices controlled in dependence of the fluid temperature and the further operating parameters of the internal combustion engine.
  • the invention has the object to perform a method of the type mentioned above in such a way that the distribution of the heat energy available in the vehicle from the heat sources optimally distributed taking into account the needs of individual heat users, so that a reduction in fuel consumption and emissions , Especially during the cold start of the internal combustion engine, is feasible.
  • a method in which an internal combustion engine, a transmission oil heat exchanger, an engine oil heat exchanger, a store for heated fluid and / or an exhaust heat exchanger deprived of heat and a passenger compartment heating heat exchanger, the internal combustion engine, the transmission oil heat exchanger, the engine oil heat exchanger, the memory and / or the exhaust gas heat exchanger is supplied heat.
  • This makes it possible that, for example, during a cold start of the engine different heat sources depending on the specific vehicle and aggregate conditions and / or customer requirements, for example, to the passenger compartment heating heat exchanger, exploited. In this case, a maximum of comfort and a minimum of consumption is realized in particular on the order of activation and deactivation of individual heat generator and heat user.
  • the accumulator is emptied by means of a particularly electrically driven pump and the warm fluid, in particular water, is fed into the internal combustion engine.
  • operating parameters are, for example, outside and inside temperature of the vehicle, temperature of the internal combustion engine, time, the state of the locking system of the vehicle, driving speed, brightness, speed and torque request of the driver and so on.
  • the pumps are switched off. This makes it possible that the warm fluid remains in the internal combustion engine and gives off heat to this.
  • the pump is switched on, the engine supply valve and the Abgastownübertragerumgehungsventil closed and the engine bypass valve are opened, wherein the fluid, bypassing the internal combustion engine, is passed through the exhaust gas heat exchanger to the passenger compartment heater.
  • the pumps arranged in the cooling circuit are driven electrically, mechanically, pneumatically and / or hydraulically.
  • a pressure equalization tank in the fluid circuit is used as storage for the heated fluid. This makes it possible that the heat energy can be stored independently of the operating state of the heat generator.
  • the surge tank as a memory, it is possible to dispense with a separate heat storage, which space in the vehicle can be saved. Also, the mass of the vehicle decreases, resulting in a reduction in fuel consumption and emissions.
  • the reservoir and / or the pressure compensation container have a volume which corresponds to the volume of the fluid lines in the internal combustion engine. As a result, the volume of the memory and thus the space requirement in the vehicle is limited to a necessary amount of fluid.
  • the invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below.
  • This shows a designed as a coolant circuit of an internal combustion engine 1 of a vehicle fluid circuit.
  • the fluid circuit has controllable devices 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 for influencing the heat balance of the internal combustion engine 1, wherein a fluid temperature and other operating parameters of the internal combustion engine 1 detected be and the controllable devices 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 depending on the fluid temperature and the other operating parameters of the internal combustion engine 1 are driven.
  • the internal combustion engine 1 a transmission oil heat exchanger 2, a motor oil heat exchanger 3, a memory 4 for heated fluid and / or an exhaust heat exchanger 5 heat withdrawn and a passenger compartment heating heat exchanger 6, the internal combustion engine 1, the transmission oil heat exchanger 2, the engine oil heat exchanger 3, the memory 4 and / or the exhaust heat exchanger 5 heat supplied.
  • the method according to the invention makes it possible, for example, for the accumulator 4 to be emptied as a function of at least one operating parameter of the vehicle and an operating parameter of the internal combustion engine 1 by means of a pump 7 and for the warm fluid to be conducted into the internal combustion engine 1.
  • the pumps 7, 8 are switched off at the start of the internal combustion engine 1.
  • the pump 7 is switched on, the engine supply valve 9 and the exhaust gas heat exchanger bypass valve 11 are closed and the engine bypass valve 10 is opened, whereby the fluid bypasses the internal combustion engine 1 and is guided through the exhaust gas heat exchanger 5 to the passenger compartment heat exchanger 6.
