26 Claims.

This invention relates to improvements in internal combustion engines of the Diesel or similar oil burning type and more specifically to two stroke cycle double acting engines particularly 5,: adaptable for heavy power purposes such as marine engines, etc., which attain sizes developing several thousand horsepower each.

In engines of this type, the matter of assembling and servicing are among other things of great importance and it is therefore an object of the present invention to provide an engine designed to permit the ready assembling and dismantling of the cylinder construction for servicing or repair without requiring the removal of the exhaust manifold, the scavenging manifold, cylinder piping, platform etc., and without interfering in any waywith the alignment of the engine.

In internal combustion engines of this typ liners in the cylinder are employed and while heretofore it has been the improved practice to make these liners in sections to facilitate their removal or replacement, they have been constructed with shoulders or other variations in cross-section, which resulted in fractures at the joint of the thin and thick 'sections of the liners during operation of the engine.

It is therefore another object of the present invention to provide an improved two cycle double acting engine of this typein which the top and bottom liners are straight bushings of uniform thickness as is also the intermediate or port section thereby avoiding section variations and the resultant fractures.

With these and other objects in view as may appear from the accompanying specification, the invention consists of various features of construction and combination of parts, which will be rst described inv connection with the accompanying drawings,.showing an internal combustion engine of the preferredvform embodying the invention and the features forming the invention will be specifically pointed out in the claims.

Fig. is a bottom plan of 4the cylinder as- Referring more particularly to the drawing corporation of Vir-` 1930. Serial No. 438,703

(Cl. 12S-61) the improved double acting oil burning internal combustion engine is of the two stroke cycle type of Diesel engine and embodies the base 1 upon which the frame 2 is mounted, the frame in turn carries the cross head structure 3, 'which serves to guide the piston rod 4 upon the upper end of which the piston 5 is mounted.

The piston 5 reciprocates in the power cylinder assembly 6 in the usual manner for imparting power to the crankshaft 7 of the engine.

The power cylinder assembly 6 includes the cylinder proper, which is composed of the upper cylinder section 10, intermediate or port section 11, and the lower or inner cylinder section 12. f

The upper cylinder section 19 has its head substantially dome shaped and is closed by the spray valve or injection valve carrying-member 14, while its lower end has an inwardly facing annular shoulder thereon together with a down'-v wardly facing shoulder 16 against which the upper face of the flange 17 of the liner 18 of the upper cylinder engages. The linerl 18 of the upper cylinder section 10 like the liner` 19 of the lower section of the cylinder 12 is of uniform thickness, with the exception of the slight annular flange 17, so as to prevent any weakened joints or sections which have been found subject to fractures in actual operation of the en.

' the annular flange 20, which is formed on the intermediate cylinder'section 1l.

The intermediate Ncylinder section 11 is of substantially uniform thickness throughout its length, departing from such uniformity of its thickness only at the end ilanges 20 and 2l against which the liners 18 and 19 respectively engage. The intermediate section 11 of the cylinder is provided with scavenging air ports 22 and exhaust Jports 23, which ports open out to corresponding ports formed in the intake and exhaust conduit member 24. Therespective scavenging` ports 22 and exhaust ports 23 open through the ports in the member 24 to the scavenging air manifold 25 andexhaust manifold 26. These manifolds 25 and 26 are supported from the intake and exhaust conduit member 24 in any suitable manner as clearly shown in Figs. 1 and 2 of the drawings.

The lower or inner cylinder section 12 has its lower or outer end substantially dome shaped and its inner end is provided with an annular flange 27, which engages Aagainst the lower end of the intermediate cylinder'section 11 and provides an outer downwardly facing clamp-shoulder 28 as well as the inner upwardly facing shoulder 29 against which the annular flange 30 of the liner 19 engages.

The lower end of the lower or inner cylinder section 12 is provided with an opening 31 through which the piston rod 4 extends.

'I'he lower end of the lower cylinder section 12 has 'a housing 32 attached thereto which forms a housing for the stuing box 33, positioned about the piston rod 4 and also forms a closure for the cooling chamber 34, being held in place and attachedr to the jacket 35 by the stuing box tensioning plate or member 36 by means of which the tension on the packing in the stung box is regulated.

'I'he jacket 35 cooperates with the lower cylinder section 12 and with the housing 32 to form the cooling water section 34 about the lower or inner cylinder section 12 and it also serves as a support for the injection valve structures 37 by means of which fuel oil is injected into the cylinder below the piston 5. The injection valves 37 andthe upper injection valve 38 may be of any approved construction.

'I'he ports 22 and 23 in the intermediate cylinder section 11 are bridged by sections of the cylinder or bridging members 39 certain of which are provided with openings 40.

The openings 40 open into the chamber 34 at the lower end of the cylinder and into the cooling chamber 41 at the upper or outer end ofthe cylinder so as to permit circulation of the cooling liquid between the chambers 34 and 41 and through the intermediate section 11 for cooling the cylinder construction. The chamber 41 is formed about the upper or outer cylinder section 10 by the jacket 42, which is attached to the injection valve-carrying block 14 and depends or hangs downwardly about the upper cylinder section 10, having its lower end free from direct connection with the cylinder section so as to permit removal of the jacket and cylinder sections and to accommodate expansion and contraction under temperature variances. A sealing ring 43 is mounted about the jacket 42 and engages the clamp ring 44 for preventing the escape or leakage of cooling/duid from the chamber 41.

It will be also noted in connection with expansion and contraction -of the parts of the engine, that the ends of the liners 18 and 19 are spaced from the respective cylinder sections 10 and 12 as shown at 45, so as to permit expansion and contraction of these members without fracture. y

The clampy ring 44 has an annular downwardly facing shoulder thereon, which engages the upwardly facing shoulder 15 on the upper cylinder section 10 and it is spaced from the upper end of the intake and exhaust conduit member 24, to which it is bolted by a relatively short bolt 47, so as to provide suicient clearance to accommodate expansion and contraction under temperature variances.

.A second clamping collar or ring 48 is provided, which is bolted tightly against the intake and exhaust conduit member 24 and has an annular upwardly facing shoulder 49 thereon thatv en- .j gages the downwardly facing shoulder 28 on the lower cylinder section 12.

The clamping collar or ring 48 is bolted to the intake and exhaust conduit member 24 by the duit member 24 serve as means for securely clamping the various cylinder sections 10, 11 and 12 and the liners 18 and 19 securely and firmly in their positions and provide a structure by means of which the cylinder sections or the piston and its rod may be withdrawn end-wise through the top of the engine with a minimum of dismantling of the engine structure, without affecting the manifolds 25 and 26 or their connections and without in any way affecting the alignment of the engine.

' The intake and exhaust conduit member 24 rests upon the cylinder base or entablature 52 in such manner that in effect, the intake and exhaust conduit member 24 together with the clamp ring 48 are as a part or one with the cylinder base 52 in distributing operating strains from the engine to the cylinder base 52 frame 2 and base 1. The intake and exhaust conduit member 24 is anchored or attached to the cylinder base 52, to the engine base 1 and consequently to the frame 2 by stress bolts 53, so as to administer or deliver the stresses from the operating or cylinder assembly end of the engine to its base and its foundation.

It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown but that these may be modified widely within the invention defined by the claims. y
