horsepower,l .a ypositive timing of' the pro liminaryfexplosion by-ineans of which the combustible fuel is expelled into the engine ycylinder may be ofV advantage. When the embodiment herein disclosed is employed,

this positive timing of the preliminary ex plosion is readily provided lor by the use of blocks 35, which are j'ii'eferably arranged in air-tight relation in the chamber 32 and are of sullicient'depth to controlboththe openings 33` and tbe openings 3l. The blocks 35 thus act as Valves andthey may conveniently bemade as lugsvwliichdepend from the ex tension 3. t 'y Fig. 3 shows the valve and the oil "cup [28 'when the piston is about to start nuits suction stroke, or 11s )ust completing" its come pression stroke. `When the piston moves and .the cup 28 move one from the position of Fig. to thel position of Fig.y e,

wherein the. valve is distant from the scat' d and the openings 3e are below the blocks 35. The suction developed by the piston in#rv duces the flow of oil and'air through the passages 6 and 7 respectively, into the upper portionof the borel and through tliejpassages 31 which lead from the groove 30 into When the requisite amount or' oil has been passed to thef cup 28, said'cnp' and the valve mfve upwardlyas one from the position of sg, back tothe position'of Fig 3, wherein projectingy arm BEST AVAILABLE COPY l S the blocks 35 Cover .the openings 33 and 3e y and thus shut ofi the communicetion between the openings 3B :und the chamber 32.

'alve and'the reservoir 28j are again operateda but in this latter instance, said valvey and said reservoir are notigiven an axial movement, but are merely turned suliciently to bring the openings 33 and 34 out of line with the blocks 35 and to thus put said openings into communication with' the chamber and the combustion space respectively. This operation, therefore, changes the reser-r voir 28 from the position of Fig. G to the position of Figs. 5, 75 and 9. Thereupon the preliminary explosion inthe reservoir 3, by which the unvaporizedoil in said reservo?" is expelled. into' the engine cylinder. takes place in the manner alreadyl explained. When the unvaporized oil in the reservoir has beene'xpelled therefrom, the valve and the-'reservoir 28 :ire again turned previous to the next suction stroke to the position ol Fig. 6, and in such position', of course, have 'the relations shown in Fig. 3 andare rendf.v
