Definitions

  • the invention relates to a method for cleaning Circuits of internal combustion engines with the help of a Cleaning device, a suction and pressure pump, a Filters, a container, a suction opening and an outlet opening Has.
  • Devices of this type which are in the cycle of a Internal combustion engine, usually a car engine Add a number of chemical substances to the liquid. The Liquid and the substances are then combined with that of the Device self-generated pressure or simply through the the effect of the internal combustion engine caused the water to circulate moved for cleaning by the circuit.
  • the motor circuit located drain plug so that the water with or without the help of a pressure pump from inside the circuit expires, usually under the vehicle. Subsequently the drain plug is reinserted and the circuit again filled, either with water or with water and a suitable one Additive, e.g. an antifreeze.
  • Additive e.g. an antifreeze.
  • WO-A-9 426 431 is a generic device known, with the help of which to be cleaned Liquid in an internal combustion engine Canister can be pumped. Then one Cleaning liquid through the cleaning device in the pumped cleaning engine. If the engine is cleaned, the Cleaning liquid removed again and the original Liquid pumped back into the internal combustion engine.
  • the present invention relates to an improved method for Cleaning circuits of internal combustion engines, in which first the inside of the circuit of the internal combustion engine contained liquid through the suction opening with the help of the suction and pressure pump is sucked off and through the filter into the container is pumped with the liquid pumped into the container Detergent is added and then again with the Suction and pressure pump connected outlet via a predetermined time through the interior of the circuit to be cleaned is pumped.
  • This invention finds application in the device and device manufacturing for the auto accessories industry Industry.
  • the inventive method for cleaning Circuits of internal combustion engines is within the Industry for which it is intended, new.
  • the procedure meets all requirements for an engine wash in a simplified Shape.
  • the cleaning device for circuits from Internal combustion engines consist of a frame, housing or Frame in the form of a parallelepiped, with associated wheels for movement, which can be of any shape.
  • the Device can also have two wheels on the underside of the bottom and have two feet that are horizontal in line with the Stand.
  • the internal combustion engine to be cleaned is immediately over a Hose or the like with one of the openings on the front of the Device connected.
  • suction and pressure pump outgoing suction is the in the circuit of the Internal fluid contained in the internal combustion engine is suctioned off completely.
  • the aspirated liquid in the container of the device arrives, it is filtered to find an existing one in the circuit To be able to determine damage.
  • any metal residues found in the filter can be Break in the circuit itself or on another drive element of the vehicle. Thus it is possible to identify the cause remove before worse damage occurs.
  • the liquid that has flowed into the container after filtering mixes with the liquid already present there with suitable additives and then slowly in pumped back the engine circuit that is cleaned. With a certain speed and a certain force or a certain pressure in the Circuit pumped liquid cleans the circuit and the cooler.
  • the device has a manometer and a clock that it starts and again after the specified time stops. The device then sucks in the liquid the additives again, so that possible residues slowly can expire. After that, the output of the engine, which is called Drain was used, closed, and the cycle and the Radiators are filled with water so that the engine is normal can work.
  • the device is removed from the to be cleaned Engine and engine circuit as well as the coolers any liquid, in the air blown inside the circuit and the cooler to completely clean and dry them. After that they are mixed with water or with water with an additive, e.g. filled with an antifreeze.
  • FIGS. 1 and 2 show, the device for cleaning Circuits of internal combustion engines a frame or a Frame 1 in the form of a parallelepiped in a known manner interconnected angle iron or similar material.
  • the Frame has inner support elements 2, the wheels or feet or one Have combination of wheels and feet, with the wheels in one Direction are arranged continuously and can be free running.
  • a support plate Near the lower end of the frame 1 is a support plate their surface arranged horizontally in the frame.
  • two holding plates 4 and 4 ' arranged the one hand the front of the frame of the Cover device and the other hand as holders for several pipes with built-in valves and regulators, as well serve a filter connected to the internal combustion engine, the Circuit to be cleaned, can be connected.
  • a left tap 15 is used to drain the circuit Contraption.
  • the left tap 15 opens and closes the drain and the water flow for a tap 14, so that in the engine and detergents and water in the coolers can be completely rinsed out.
  • a central valve 15a regulates the pressure of a pump 7 for the Engine and radiator washing, as well as the water flow to the engine.
  • On this line is one of an air inlet and one Manometer 12 arranged device 13 which is removing the water from the engine and the radiators with the help of air regulates and ensures that the water of the circuit from the Inside the engine and the radiator completely in the Device collecting container flows.
  • Another tap 15b is on the right on the front side not far from that Water inflow to the engine arranged. Located on this line the tap 14 for the water supply from the network to the device, i.e. to the water tank.
  • the device for performing the method has a filter 6 for the residues from the engine circuit and the radiators, one Outlet opening 17 for the water from the device to the engine connected to the outlet opening 18, and the suction opening 19 for the water from the engine.
