Definitions

  • the present invention generally relates to a structure of oil control valve for variable lift of engine valve, and more particularly to a structure that prevents an oil control valve from interfering with maintenance operations of other components and shortens a controlling oil passage between the oil control valve and an oil-control driving mechanism so as to reduce loss of oil pressure and also make the oil control valve controlling and driving the oil-control driving mechanism more precisely.
  • FIG 1 An arrangement of oil passage for a variable valve lift mechanism used in a conventional engine 1 is illustrated in FIG 1 , where an electromagnetic valve 2 is mounted atop a cylinder head 11.
  • Lubricant oil flowing through an oil pressure inlet is guided by an oil tube 21 to directly introduce the external oil pressure into the electromagnetic valve 2 to allow the electromagnetic valve 2 to conduct the lubricant oil into oil passages inside the cylinder head 11 so that the oil pressure can be used to drive the variable lift mechanism of each cylinder to cope with switching between intake and exhaust valves of different lifts at different rotational speeds of the engine 1.
  • the conventional engine 1 adopts the arrangement of the electromagnetic valve 2 and the oil tube 21 to achieve switching between intake and exhaust valves of different lifts for matching the rotational speeds of the engine 1.
  • the electromagnetic valve 2 since the electromagnetic valve 2 is mounted by a plurality of bolts 22 to the cylinder head 11, the assembling is complicated. Further, the oil tube 21 externally connected to the electromagnetic valve 2 is susceptible to oil leaking and in addition, it is exposed outside the engine 1 so that it may get embrittled and thus damaged due to high temperature of the engine 1. Further, since the electromagnetic valve 2 is arranged atop the cylinder head 11, the electromagnetic valve 2 may easily interfere with a component on the upper side, such as a storage box, when the engine 1 swings.
  • EP 2 381 074 A1 describes an engine having an oil control valve. However, no discussion has been provided by EP 2 381 074 A1 regarding the arrangement of the oil control valve to prevent heat accumulation around the oil control valve and to protect the oil control valve from damages caused by high temperature of the engine.
  • the primary technical solution of the present invention is that a structure of oil control valve for variable lift of engine valve is provided.
  • the engine at least comprises a crankcase, a cylinder block mounted on the crankcase, and a cylinder head mounted on the cylinder block.
  • the cylinder block comprises a timing chain compartment, which extends upward to the cylinder head.
  • the timing chain compartment receives a timing chain mounted therein.
  • the cylinder head comprises a rocker arm compartment, which comprises a cam assembly, a rocker arm assembly, and a valve assembly mounted therein, wherein the rocker arm assembly comprises an oil-control driving mechanism and the oil-control driving mechanism is controlled by an oil control valve.
  • An oil control valve mounting base is mounted on a surface of the cylinder head that is on the same side as the intake port.
  • the oil control valve mounting base comprises a coupling seat and an insertion seat.
  • the oil control valve comprises a valve body and an insertion section.
  • the insertion seat of the oil control valve mounting base receives the insertion section of the oil control valve to insert therein, wherein the insertion seat of the oil control valve mounting base and the cylinder head are spaced from each other by a spacing distance.
  • the oil control valve is set distant from the high temperature site of the engine to prevent the oil control valve mounting base from forming a heat accumulation object thereby improving the durability of the oil control valve, easing the installation of the oil control valve, and preventing the oil control valve from interfering with the maintenance operation of other components. Further, this also helps shorten the controlling oil passage between the oil control valve and the oil-control driving mechanism to thereby reduce loss of oil pressure and make the oil control valve controlling and driving the oil-control driving mechanism more precisely.
  • the present invention provides an engine 3, which at least comprises a crankcase 31, a cylinder block 32 mounted on the crankcase 31, and a cylinder head 33 mounted on the cylinder block 32.
  • the cylinder block 32 comprises a timing chain compartment 34.
  • the timing chain compartment 34 extends upward to the cylinder head 33 and a rocker arm compartment 35 formed on the cylinder head 33.
  • the timing chain compartment 34 receives a timing chain 341 mounted therein.
  • the cylinder head 33 comprises the rocker arm compartment 35 and the rocker arm compartment 35 comprises a cam assembly 351, a rocker arm assembly 352, and a valve assembly 353 mounted therein.
  • the rocker arm assembly 352 comprises an oil-control driving mechanism 354.
  • the oil-control driving mechanism 354 is controlled by an oil control valve 4.
  • the oil control valve 4 comprises a valve body 4a and an insertion section 4b, whereby the oil control valve 4 controls and drives the oil-control driving mechanism 354 and the oil-control driving mechanism 354 in turn causes the valve assembly 353 to do movements of different high and low lifts.
  • the cylinder head 33 comprises an intake port 331 located at the intake side.
  • the intake port 331 is connected to an intake duct 3311 and the intake duct 3311 is connected to a throttle valve 5 and an electronic control unit (ECU) 6, as shown in FIG 2 .

  • the oil control valve mounting base 334 is mounted in such a manner as to form a spacing distance between the insertion seat 3342 of the oil control valve mounting base 334 and the cylinder head 33, as shown in FIG 2 .
  • the insertion seat 3342 of the oil control valve mounting base 334 is set to extend in a direction toward the crankcase 31 and is arranged on the cylinder head 33 to be substantially parallel to or form an acute angle with respect to the intake duct 3311.
  • the oil control valve mounting base 334 and the oil control valve 4 are set on the surface of the cylinder head 33 that is on the same side as the intake port 331 between the intake port 331 and the igniter mounting base 333 in such a way that the oil control valve mounting base 334 is located on the second quadrant of the engine 3, as shown in FIG 5 , whereby a controlling oil passage 41 between the oil control valve 4 and the oil-control driving mechanism 354 can be effectively shortened, as shown in FIG 2 , and thus, the operation of the oil control valve 4 controlling and driving the oil-control driving mechanism 354 can be made more precisely. Also, it is possible to prevent the formation of a heat accumulation object on the oil control valve mounting base 334 and prevent high temperature from transferring from the cylinder head 33 to the oil control valve mounting base 334 and the oil control valve 4 to thereby improve durability of the oil control valve 4.

  • the engine 3 can be an air-cooling engine 3a or a water-cooling engine 3b.
  • a cooling fan 311 is provided at one side of the crankcase 31 and an airflow guide hood 7 encloses the cylinder block 32 and the cylinder head 33.
  • the oil control valve mounting base 334 and the oil control valve 4 are mounted to the cylinder head 33 at the same side of a cylinder axis A as the cooling fan 311.
  • the cooling fan 311 draws in cold air from the surroundings and the airflow guide hood 7 conducts the cold air toward the cylinder block 32 and the cylinder head 33 so as to cool and dissipate heat from the cylinder block 32 and the cylinder head 33. As shown in FIGS.
  • the oil control valve mounting base 334 and the oil control valve 4 are mounted to the cylinder head 33 in such a way that the insertion seat 3342 of the oil control valve mounting base 334 is set at a spacing distance from the cylinder head 33 and extends in a direction toward the crankcase 31 and is arranged on the cylinder head 33 to be substantially parallel to or form an acute angle with respect to the intake duct 3311.
