8 Claims.
The invention relates to V-type combustion engines and consists in a new type of frame construction for such engines, providing unusual strength and rigidity with minimum weight per horse-power, being particularly suitable for twocycle port-scavanged engines. The principle of the new construction is shown by way of example in the accompanying drawing, wherein Fig. 1 is a vertical transverse section on line I---I of Fig. 2, and
Fig. 2 is a plan view in the direction of the arrows IIII of Fig. l.
The new frame is composed of similar cylinder blocks each containing several combustion spaces or cylinders, and symmetrically set at a V-angle of 45 more or less. Each block is constituted of substantially flat longitudinal side walls I and 2 connected at their tops by a top plate 3, and between adjacent cylinders by cross partitions 4, as well as by the port passage belts 5, all as will be plain from the drawing. The detail construction of the cylinder blocks is not of importance to the present invention, it being noted that the cylinders proper of any appropriate number, occupy the circular openings 6 and are intended to be covered'by cylinder heads not sho n but bolted to the top plate 3.- The frame is shown as formed of a single casting but may be in parts welded or otherwise united, as preferred.
According to this invention the two angularlyrelated cylinder blocks are cross-bonded each to the other by a number of vertical cross plates, transepting the trough between them and uniting their longitudinal walls into a structure which is essentially that of a girder. There is one set of such cross plates, marked 1, aligned with the cross partitions 4 of the right- -hand cylinder block and another set, 8, aligned with the cross partitions 4 of the left-hand cylinder block. Owing to the offset of opposing cylinders, necessary for the accommodation of their connecting rods on common crank-pins, the cross partitions 4 of the opposing blocks are not in common planes and the corresponding cross plates 1 and 8 overlap each other, in the trough, being spaced from each other by a short distance in each case corresponding to the amount of ofiset. The cross plates of both sets are prefmg angularly-related cylinder blocks forming a 50 erably flanged along their top edges, as indicated at l and 8 respectively. and such top edges are sloped downwardly from one cylinder block toward the other, that is to say, the flanges I on the plates 1 which are aligned with the cross partitions 4 of the right-hand block slope down- (Cl. l21194) wardly to points of connection with the wall of the other block and similarly the top flanges 8 or the cross plates 8 slope from the left block to points low down on the right block. In both cases the points of connection just referred to are located below the rows of openings 9 which I lead from the trough into the cylinder ports.
It is preferable that the cross plates of each pair be connected to each other where they overlap in the trough and to this end the top flange 10 of one plateis extended as a fillet to the adjacent plate. The fillets are marked 1 and 8 respectively. Also recesses or apertures III are formed in the cross plates 1 and 8 at the bottom of the trough which allow for draining the trough when necessary through the drain hole marked II in one of the end walls.
The girder system constituted, as above described, by the longitudinal angularly-related block walls and the transverse cross plates, each a virtual continuation of a cross partition 4, and all interconnected, is exceptionally wall adapted to resist the torsional strains that occur in V- type combustion engines, and constitutes an important factor in the adaptation of Diesel-type engines to vehicular propulsion where a low weight-power ratio is required.
