Definitions

  • This invention relates to engines.
  • the present invention provides a novel engine wherein the cylinder of the engine is configured as an annular cylinder having pairs of opposed pistons cooperating therein.
  • the two pistons of each pair are interconnected by a curvilinear tie rod to one end of a rocker arm, there being two such intersecting rocker arms pivotally mounted about a common axis.
  • the rocker arms are joined by a crank apparatus to the gear system for the engine for converting the oscillatory movement of the rocker arms into a rotary motion in the gears.
  • the engine of the invention is suitable for (a) two-stroke, or four-stroke internal combustion engine operation, (b) two-stroke external combustion engine operation, or (c) in combination with a.compressor configuration.
  • Pistons 25 and 27 are mounted to tie rod 18 joined to end 12b of rocker arm 12 while pistons.27 and 28 are mounted to the ends of tie rod 19 secured to end 14b of rocker arm 14.
  • An annular cylinder 11 contains cylinder liners 36 - 39 so that coacting pairs of pistons form compression/ combustion chambers 31--34, respectively, therein.
  • pistons 21 and 28 cooperate in cylinder liner 36 to form combustion/compression chamber 31.
  • the same features are found for each of the remaining pistons 22 - 27, as will be clearly seen from each of Figures 1 - 4.
  • each of compression/combustion chambers 31 - 34 are configured as internal combustion chambers having spark plugs 41 - 44, respectively, mounted therein.
  • the_ reverse movement of each of pistons 21 - 28 is a power/expansion stroke wherein a fuel/air mixture is appropriately ignited and combusted in combustion chambers 31 - 34.
  • each forward movement of pistons 21 - 28 in combination with the respective opposing piston serves as a compression stroke to compress a fuel/air mixture in the respective combustion chambers 31 - 34.
  • Intake and exhaust ports are provided through the walls of annular cylinder chamber 11 and Irrespective cylinder liners 36 - 39 therein.
  • intake ports 61 and 68 are provided for combustion chamber 3 1 while intake ports 62 and 63 provide intake for combustion chamber 32; intake ports 64 and 65 for combustion chamber 33; and intake ports 66 and 67 for combustion chamber 34.
  • Each of intake ports 61 - 68 are selectively interconnected through intake plenum chambers 51 - 58, respectively, each of which is selectively connected to an intake header (not shown) by intake conduits 51a - 58a, respectively.
  • each cfpistons 21 - 28 operates substantially identical to piston 21 in that reverse movement of piston 21 exposes intake port 61 thereby allowing an appropriate fuel/air mixture to be introduced from the intake header (not shown) through intake conduit 51a into intake plenum chamber 51 thence through intake port 61 into combustion chamber 31. Forward movement of piston 21 covers intake port 61 and commences the compression of the fuel/air mixture thus obtained.
  • Exhaust from combustion chamber 31 is discharged through exhaust ports 71 and 78 into exhaust plenum chamber 61 and vented through exhaust conduit 61a into an exhaust header (not shown).
  • Corresponding exhaust ports 72 and 73 discharge into exhaust plenum chamber 61 and through exhaust conduit 62a.
  • Exhaust ports 74 and 75 discharge into exhaust plenum chamber 63 and exhaust conduit 63a.
  • Exhaust ports 76 and 77 discharge into exhaust plenum chamber 64 and exhaust conduit 64a.
  • a fuel/air mixture in combustion chamber 31 is ignited at an appropriate time by a spark produced by spark plug 41 with the resulting increase in pressure forcing apart pistons 21 and 28, thereby transmitting the appropriate power through cranks 48 and 49 to side gears 46 and 47, respectively, and ultimately into main gear 59.
  • pistons 21 and 28 exposes exhaust ports 71 and 78, respectively, allowing the burned fuel/air mixture to be discharged from combustion chamber 31.
  • intake ports 61 and 68 respectively, accommodating the inrush of a.fresh charge of fuel/air mixture with the initial portions of the fuel/air mixture assisting in purging the exhaust products through exhaust ports 71 and 78, respectively.
  • novel two-cycle engine apparatus of this invention provides the additional advantage-in that the end of each power stroke of one set of pistons is balanced by the compression encountered by the opposing pistons, thereby cushioning the same and assisting in the reverse movement of each of the respective sets of pistons.
  • a third preferred embodiment of the novel engine apparatus of this invention is shown generally at 30 and is configured as a four-cycle, internal combustion engine.
  • each of combustion chambers 31 - 34 incorporates therein a set of intake valves 91 - 94 and a set of exhaust valves 95 98 respectively.
  • Intake valves 91 - 94 and exhaust valves 95 - 98 are operated by the appropriate, conventional valve actuation systems (not shown) operated by a cam-driven valve lifter system (not shown).
  • a specified valve system is shown for the novel engine apparatus of this invention, it should be clearly understood that any suitable valve system could be incorporated into the novel engine apparatus and method of this invention.
  • a power cycle is commenced by the ignition of a fuel/air mixture in combustion chamber 31 by spark plug 41 igniting the fuel/air mixture with the resultant explosion, forcing apart pistons 21 and 28.
  • exhaust valve 98 is opened, allowing the exhaust products to be discharged from combustion chamber 31.
  • intake valve 91 is opened allowing a fresh fuel/air mixture to enter combustion chamber 31.
  • intake valve 91 is closed so that as pistons 21 and 28 move toward each other, the fuel/air mixture in combustion chamber 31 is compressed.
  • a spark as suitably timed for the speed of operation, etc., as is conventional, from spark plug 41 initiates combustion of the same, commencing the power stroke.
  • the power thus generated is transmitted to rocker arms 12 and 14 and translated into rotary motion by cranks 48 and 49, respectively, and transmitted by side gears 46 and 47 to main gear 59.
  • combustion chambers 31 and 33 While each of opposed combustion chamber pairs, combustion chambers 31 and 33, as opposed to combustion chambers 32 and 34, may be paired so as to both operate on the same intake, compression, expansion and exhaust cycles, the opposing combustion chambers and valve systems may be configured so as to be directly out of phase with the opposing combustion chamber.
  • combustion chamber 31 While combustion chamber 31 is in the expansion/power stroke mode, combustion chamber 33 would be in the intake mode.. Simultaneously, combustion chamber 32 would be in the exhaust mode while combustion chamber 34 would be in the compression mode of operation. Accordingly, since there are four combustion chambers, combustion chambers 31 - 34, each combustion chamber would be selectively timed so as to fire sequentially, thereby substantially smoothing out the overall operation of four-cycle engine apparatus 30.
  • a combination two-cycle, internal combustion engine/ compressor apparatus is shown generally at 40 and includes combustion chambers 31 and 33 on opposite sides thereof with compression chambers 32:and 34 in place of the previous internal combustion chambers.
  • each of internal combustion chambers 31 and 33 is operated as conventional, two-cycle internal combustion engine apparatus involving the appropriate intake and exhaust ports and fuel ignition as set forth hereinbefore with respect to the two-cycle engine apparatus 20 shown in Figure 2.
  • compression chambers 32 and 34 are configured as compressor chambers with intake valves 92 and 94 and exhaust valves 96 and 98. Accordingly, during a power stroke from each of combustion chambers 31 and 33, the corresponding pistons 22 and 23 compress a gaseous mixture in compression chamber 32 while corresponding pistons 26 and 27 compress the gaseous medium in compression chamber 34.
  • exhaust valves 96 and 98 are opened, allowing the compressed air to be discharged into the high pressure system (not shown).
  • exhaust valves 96 and 98 are closed while intake valves 92 and 94 are opened so that air is drawn into the particular compression chamber.
  • Figure 4 embodiment may be modified so that the combustion chambers are separated by 90° rather than being diametrically opposite, for example chambers 3 1 and 34 are combustion chambers and each are provided with fuel ignition means and appropriate intake and exhaust ports.
  • the compression chambers are then also separated by 90°, for example chambers 32 and 33, and are configured with similar intake valves and exhaust valves.
  • Engine apparatus 10 is shown in perspective and is specifically configured for operations as a diesel engine in that fuel injection is provided through fuel injectors 101 - 104 into the appropriate combustion chambers.
  • the valving system may be provided either as a two-cycle engine apparatus utilizing intake valves 61 - 68 and exhaust valve 71 - 78 ( Figure 2) or as a four-cycle system utilizing intake valves 91 - 95 and exhaust valves 95 - 98 ( Figure 3).
  • the diesel engine apparatus 10 of this particular embodiment incorporates fuel injector systems 101 - 104 and may be supplemented with an appropriate glow plug or spark plug, such as spark plugs 41 - 44 ( Figures 2 and 3).
  • power transmitted to shaft 29 by main gear 59 is directed through gear housing 105 into transmission/differential 106 with the power being directed to shafts 107 and 108.
  • shafts 107 and 108 are shown as axles for a front-drive vehicle. However, only one shaft, shaft 107 and 108, need be utilized for other applications. In the event both shafts 107 and 108 provide power to a front-drive vehicle, transmission/ differential 106 provides the necessary gearing arrangement and differential characteristics to accommodate such an application.
  • engine apparatus 10 The entire structure of engine apparatus 10 is enclosed in an engine housing 100, the engine housing serving also as a support bearing surface for cranks 48 and 49.
  • a take-off pulley 111 is provided on shaft 29 and drives a belt 110 to drive the appropriate auxiliary equipment (not shown), as is conventional.
