Definitions

  • the invention refers to the mechanical engineering industry, more properly to the internal combustion engine gas-distributing device configuration improvement.
  • the injecting and exhausting gas valve timing occurs in automatic mode in relation to the load applied to the engine shaft and the shaft speed.
  • the gas valve timing mechanism function is in timed injection of the fuel-air mixture or air in the engine cylinders and the flue gas extraction from them.
  • the mechanism configuration and parameters varies depending on the number of cylinders, their volume or the mode of engine use.
  • the vehicle engines are generally equipped with the valve mechanism, which assure complete gas exchange at a high engine speed, when the engine is reaching the maximal power.
  • the injection and the exhaustion processes are the result of the consistent valves, driving mechanism and camshaft operation.
  • the gas valve timing mechanism efficiency is evaluated in case of the multi cylinder engine by the coefficient of admission and the uniformity of each cylinder admission. To obtain the better cylinder admission and flue gas emission, both the admission and the emission valves should be opened and closed before or after the piston changes its stroke in the dead centers.
  • valves opening and closing angle is assigned depending on the crankshaft rotation angle.
  • the maximal values of the piston stroke and the orifice area, as well as valve timing do not specify in complete mode the valves performance and the valve timing mechanism operation.
  • Such a parameter as time cross-section which specify as orifice area, as well as duration of the flow passage can be used for more complete evaluation purpose.
  • Generally known internal combustion engine valve timing mechanisms are presented on the fig.1 , where: a, b, c and d - are the mechanisms with overhead camshaft and valves; e - mechanisms with overhead valves and underneath camshaft; f - mechanisms with lower valves.
  • the fig.1 positions are as follows: 1 - camshaft with cams; 2 - valve; 3 - spring; 4, 5, 6 - cross member; 7 - pushrod; 8 - cylindrical pusher.
  • the valve timing mechanism is known (fig. 2a), where fore each cylinder there are four gas distribution valves, at that there is a couple of camshafts in the flow head.
  • One of the two is intended for simultaneous closing and opening for the defined time of the two admission ports 9 by means of two valves 10 situated on the same side of the combustion chamber 14.
  • the invention scope is:
  • admission 9 and emission 12 ducts, as well as admission 10 and emission 11 valves all are situated in the engine flow head;
  • the power drive from the crankshaft to the gear 23 is made by the mechanism shaft 15, gear 22 and slide bushing 28, with built-in crosspiece 18, but the gears 19 and 25 teeth have opposite spiral direction;
  • the fig. 2b shows the admission 9 / 10 and emission 12 / 11 ducts / valves arrangement for one cylinder and the gas flows directions according to the invention, to assure the automatic valve timing adjustment;
  • - the fig.3a and 3b show rocker arms 33 arrangement on the axles 32 and 34, as well as the admission 30 and emission 31 cams arrangement on the camshaft and their interaction with the admission 10 and emission 11 valves;
  • - the fig.4 and fig.5 show the proposed device kinematic diagrams for two possible versions of the device realization;
  • the fig.6a, b, c, d show the proposed device admission and emission phase plain state changes during the engine operation in relation to the engine load and speed: a - idle run, b - low speed, c - high speed, d - extremely high speed.
  • the following notations are used on the mentioned figures: 9 - admission duct;
  • gear 23 is driven by the crankshaft.
  • the gear 20 and the camshaft 21 , as well as the gear 27 and the camshaft 26 rotate in the opposite direction to the governor shaft 15.
  • the gear 23 through the shaft 15 drives the gear 22, which is all-the time coupled with gear type slide bushing 28.
  • the gears 19 and 25 are placed at the definite distance one from another and together with the crosspiece 18 can move along the gear 22 in axial direction depending on the weight 17 position. As at the engine low speed the weight 17 centrifugal force is relatively low, the valve timing corresponds to the state, shown in the fig. 6a.
  • the weight 17 centrifugal force also increases and overcoming the spring 24 resistance shifts the gears 19 un 25, which in their turn pivot the gears 20 and 27, and camshafts 21 and 26 each in its direction owing to the opposite teeth spiral.
  • the cams of the camshafts 21 and 26 turn in the opposite directions, thus causing more wide admission and emission valve timing.
  • the valve timing in this case, corresponds to the state, shown in the fig. 6b.
  • the valve timing state at higher speeds is illustrated in the fig. 6c and fig. 6d.
  • the speed of the overloaded engine decreases, causing the weight 17 centrifugal force decreasing. So, the spring 24 through the gears 19 and 25 get the camshafts 21 and 26 back in the initial position, causing gradual valve timing transfer from the state as in the fig. 6d to the lower 6c- state and further to the still lower 6b- and 6a- states.
  • valve timing governor configuration (fig. 4) kinematic diagram is built like four helical gears 19, 20, 25 and 27 all-time coupling, where the gear couples 19 and 20, and 25 and 27 have opposite teeth spiral directions.
  • the admission 10 and emission 10 valves of the engine combustion chamber are disposed as in the fig. 2b.
  • the two camshafts 21 and 26 similar by design to those used on the engine of two camshaft types, that is one for the admission valves and the other for the emission valves per cylinder.
  • Such type of the valves arrangement (fig. 2b) at the inlet creates the turbulent flow, favoring the fuel-air mixing and its combustion process.
  • the emission valve opening occurs the better condition for the exhaust gas exit.
  • valve timing mechanism used to drive the gas-distributing device (fig. 4 or fig. 5).
  • the camshafts 21 and 26 are pivoted in the opposite directions when the engine reaches the certain speed. This pivoting results in the admission cam

  • admission 30 and emission 31 cams on each of the camshafts 21 and 26, which through the axle 34 and the rocker arm 33 operate the admission 10 and emission 11 valves.
  • the camshafts 21 and 26 are pivoted in the opposite directions when the engine reaches the certain speed. This pivoting results in the admission cam 30 on the camshaft 21 acts on one of the admission valves 10.
  • the second admission valve 10 is acted upon through the rocker arm 33 by the admission cam 30, fixed on the second camshaft 26, which, driven by the governor (fig. 4 or fig.5), is pivoted in the direction opposite to the camshaft 21.
  • cams 30 displacement in the opposite directions is realized, thus giving wider valve timing on admission.
  • the camshaft 26 emission cam 31 acts on one of the emission valves 11 , at that the other emission valve 11 is acted upon through the rocker arm 33, fixed on the axle 34, by the cam 31 fixed on the camshaft 21.
  • the gearbox (fig. 4 or fig. 5) turns the camshafts 21 and 26 in the opposite directions. In this way the cams 31 displacement in the opposite directions is realized, thus giving wider valve timing on emission.
  • the device can be made on the base of the existing gas distributing mechanisms elements; - it is possible to reduce the engine idle run speed up to 400 rpm and even lower, at that the engine works steadily without vibrations;
