Definitions

  • the invention relates to a device for venting a crankcase an intake engine comprising an internal combustion engine with a Outlet for gases on the crankcase and a return line the crankcase gases into the intake area.
  • crankcase gases When operating internal combustion engines, it is unavoidable that gases from Pass the combustion chamber past the piston rings into the crankcase. These gases are commonly referred to as blowby gases and Condition especially in a piston movement in the direction of the lower Tot Vietnameses UT a pressure increase in the crankcase. Usually, therefore provided a vent for the crankcase, via which a Pressure reduction can be done.
  • the discharged crankcase gases are by means of a vent line, for example in the intake of the Internal combustion engine recirculated, sucked from there and combustion fed.
  • due to the operational movement and Crankcase temperature is due to the crankcase breather oil to be discharged. If these oil-laden gases are burned, are an increased jingle hazard, a shortened catalyst life and / or deteriorated exhaust emissions, the result. It is therefore necessary Oil separation measures to meet the oil loading of at least reduced crankcase gases.
  • a Crankcase breather for an internal combustion engine with an arrangement for the separation of oil from the discharged air, which is within the Crankcase arranged in the region of a vent line, includes rotating impeller with blades.
  • the spinner wheel body is formed like a disk and carries radially extending blades, which in Schleuderradachscardi in the direction of Lucasabströmstutzens extend.
  • the inlet opening of the Lucasabströmstutzens is at least arranged approximately coaxial with the blast wheel and the opening plane at the spin wheel level at least approximately parallel, so that the inlet end of the Lucasabströmstutzens with the airabststutzen side Blade edges of the rotating blast wheel one Includes flow gap.
  • the in the German patent application 102 36 332.3-13 described crankcase ventilation is very compact constructed, consists of only a few components and is therefore inexpensive to manufacture. and mountable. Furthermore, the crankcase ventilation is characterized by a particularly good effectiveness especially at a high Application of oil to be discharged gases. It has, however proved that this single action is very powerful Internal combustion engines as well as with particularly stringent requirements exhaust emissions reach their limits.
  • DE 100 53 096 A1 discloses a device for venting a Crankcase of an internal combustion engine by means of a valve, wherein the Valve stationary in a partition wall, which is the interior of the crankcase is divided into an upper space and a lower space is arranged.
  • the described arrangement leads by the reduction of Air pressure fluctuations in the crankcase to a lower oil load in the crankcase and less oil foaming in the oil circuit.
  • both power and torque are the Internal combustion engine by reducing friction losses on the crank mechanism elevated. Also this individual measure is very effective in itself, However, in very powerful internal combustion engines as well as in particularly stringent exhaust emission requirements alone sufficient.
  • German patent application 102 36 332.3-13 and the DE 100 53 096 A1 belong to the full extent with all features Disclosure of the present application. They contribute to technical aim of the invention and thus to solve the according to the invention according to the invention underlying technical task at.
  • the request for protection may apply to all characteristics, individually or in Combination, extend.
  • the object of the invention is to provide an aforementioned device for Ventilation of a crankcase of a intake area comprehensive Internal combustion engine with an outlet for gases on the crankcase as well a line for returning the crankcase gases in the To provide intake, which is also very powerful Internal combustion engines and / or particularly stringent requirements for the Exhaust gas values is sufficiently effective.
  • the partition advantageously divides the interior the crankcase in an overhead crank chamber and a underlying oil space. As it is considered very useful if the Valve is pressure controlled or actuated by an actuator.
  • the second one Functional area formed by a blast wheel with blades whose Blade with the entry area of a vent line a (ring) gap lock in.
  • the blast wheel in the process Operation on the bleeding flow in the opposite direction.
  • the third functional area is according to a particularly preferred Embodiment formed with a knitted fabric separator, which advantageously in the vent line the impeller immediately is subordinate. It is very useful when recording the Knitted separator the vent line a diameter-expanded Has area.
  • the Knitted fabric separator made of a metallic or organic material or from a fuel and oil resistant plastic.
  • the vent line is Appropriately, starting from the crankcase to the intake arranged steadily rising.
  • FIG. 1 shows a two-cylinder internal combustion engine 100 in box construction in sectional view from the front.
  • the internal combustion engine comprises two cylinders which enclose an angle of 180 °, with opposite in operation moving piston 106.
  • this Type is due to the at the same time to UT or top dead center OT moving piston 106, the device according to the invention particularly advantageous. For clarity, only one page is referred to in the present case.
  • the pistons 106 delimit combustion chambers 120 in the direction of the crankshaft 122, for sealing the combustion chambers 120 in the region of the piston 106 against the Cylinder running piston rings 112 are provided.
  • At very high pressure in the combustion chambers 120 in particular in the combustion cycle, can nevertheless according to the arrows as blowby gases designated gases from the combustion chambers past the Kolberingen 112 in the crank chamber 114 penetrate, causing a pressure increase in the crank chamber 114th entails.
  • the crankcase 102 by means of a partition 118 in an upper space 114 and a lower space 124 divided.
  • a valve 110 for example, a diaphragm valve provided, which at an elevated Pressure in the crank chamber 114 a pressure equalization according to drawn arrow into the lower space 124 allows.
  • the valve 110 is particularly suitable, which goes back to the piston movement To smooth pressure pulsation.
  • the lower space 124 is associated with an oil sump 116 and wells 108th for receiving timing chains, not shown here, through which a further discharge of blowby gases according to the drawn Arrows in the direction of the cylinder heads 104 takes place.
  • a discharge the oil-laden blowby gases according to the arrows past a blast wheel 232, soft by means of a shaft 230 is drivable in a vent line 238.
  • the Shaft 230 a camshaft, which end the impeller 232 receives.
  • the blower wheel 232 has a disk-like base body which extends in the direction of the inlet of the vent line 238 extending, radially arranged wing carries. The outer wing edges when rotated with the inlet of the vent line 238 (Ring) gap, which the blowby gases pass in the ventilation direction.
  • the blower wheel 232 promotes rotation against the flow direction the blowby gases, so that a first oil separation is achieved by Oil drops of turbulent flow can not follow, on blades of the impeller 232 knock down and back to the oil sump 216 be supplied.
  • Knitted fabric consists for example of a metallic or organic Material or from a fuel and oil resistant plastic. At the Passage through the fabric bounces in the blowby gas still entrained Oil drops against the conduction walls or fibers, agglomerate, run Gravity down along the walls or fibers down, collect there and finally by means of the paddle wheel 232 promoted back to the oil room.
  • vent line 238 extends from the crankcase 202 steadily rising and flows into the intake 236 of the Internal combustion engine 200.
