摘要： In order to avoid the danger of overheating the separate exhaust jacket of a water-cooled internal combustion engine with a sound-absorbing cover whose enclosed space contains air inlet and outlet openings sealed against the penetration of sound, and is ventilated by cooling air during operation of the engine, and which has a separate exhaust jacket with air ducts of its own-with a radiator cooling fan being placed outside of the cover in the vicinity of a cover wall serving as a radial deflector for the outgoing air from the fan, and with the exhaust jacket leading substantially upwards from its outlet to its inlet opening-after the engine has been switched off and the forced ventilation has thus come to a standstill, the air inlet opening leading into the exhaust jacket is connected to the topmost part of this jacket and is positioned such as to be exposed to the flow of outgoing air from the fan.

摘要： In a water-cooled, multi-cylinder internal combustion engine, which comprises cylinders and a cooling jacket, the cylinders are connected in the lower region thereof to each other and to the cooling jacket, and crankshaft main bearings consisting of two parts which are mutually connected by means of main bearing bolts, the lower ends of the cylinders are connected to the cooling jacket at a height from the bottom edge of the cylinders corresponding to 0.5 to 0.75 times the cylinder diameter, and downwards from this level the lower cylinder ends are connected to each other but otherwise free and unconstrained, and the threads for the main bearing bolts are arranged at a height from the bottom edges being at least that great as the distance of the connection between the cylinders to the bottom edges.Thereby, reaction forces from the main bearing bolts are transmitted directly to the region above the connection between the cylinders and the cooling jacket or are transmitted through the junction between the cylinders and cooling jacket and distributed to the cylinders and the cooling jacket in that region thereof which is above the junction. The unconstrained lower end of each cylinder is free from reaction forces thus avoiding unacceptable deformation in this region. Also, it is possible to choose a comparatively small working clearance between piston and cylinder which means less noise generation. Moreover, piston rings with lower tensions may be used, which means lower friction and, owing to the drastically reduced liner deformation, also less oil consumption.

摘要： In a water-cooled, multi-cylinder internal combustion engine, which comprises a cylinder block, a cylinder head, and a cooling jacket, all cast in one piece and wherein the cylinder head comprises, for each cylinder of the cylinder block and on one longitudinal side thereof, an intake and exhaust duct as well as valve guide sockets and on the other longitudinal side a mounting socket for an injection nozzle or sparking plug, forming a connection between the end wall of the cylinder and the cooling jacket, at least one fin is provided on the side where the mounting socket is arranged to make an additional connection between the end wall of the cylinder and the cooling jacket.This arrangement compensates for the differential section modulus between the two longitudinal sides of the cylinder head regarded as a bending section, that is to say, the neutral axis of the cylinder head is shifted, at least approximately, back into the plane which contains the cylinder axes. This achieves an even distribution of combustion forces from the end wall of the cylinder to the cooling jacket and by comparison with the conventional arrangement reduces noise emission from the exposed longitudinal sides of the cylinder head.

摘要： In an internal combustion engine the power generating parts mainly responsible for body resonance and sound vibration such as the crankshaft (3), cylinder block and cylinder head (35) are combined in a power unit which is supported in the crankcase (4) on elastic vibration-absorbing mountings (2) with the sidewalls of the crankcase (4) extending above the crankshaft axis (3).By this arrangement the crankcase (4) is free from direct vibrations leaving other non-power transmitting engine parts mounted above the crankcase (4) which require means to suppress radiated noise.In one embodiment the induction manifold (7) and mounting parts (13, 14) thereof together with the rocker cover (20) are insulated from the cylinder head (35) by vibration-absorbing elements (8,15,16,21,26) and are so shaped and arranged that they provide a screen for noise radiated from the cylinder head (35). Thus, essential parts of the engine have the secondary function of reducing the level of noise emitted by the engine.

摘要： A fuel injection pump for a compression-ignition engine includes a cylinder having a bore therein and a pump piston which is mounted not only to reciprocate within the bore past a fuel supply port but also rotate therewithin. The pump piston has upper and lower control surfaces which each have a bowed shape. The center or centers of the control edges lies or lie above them, and in the region between the upper part loads and full load in the direction towards full load the upper control edge has a rising shape while the lower control edge has a falling shape. The lower control edge, by comparison with the remainder of its extent falls progressively less steeply towards full load and the upper control edge rises increasingly steeply, so that the compensation of delivery in accordance with speed is achieved predominantly by the upper control edge and there is obtained a speed-dependent advance of the start of delivery.

摘要： A cylinder head for an air-cooled internal combustion engine having its intake and its exhaust ducts each arranged transversely to the direction of cooling air flow and having groups of cooling fins arranged vertically and perpendicularly with respect to the cylinder axis and air leading surfaces. The groups of cooling fins and the air-leading surfaces are located with respect to each other such that the cooling air is split into a number of partial cooling air streams, thus enabling controlled cooling of the entire cylinder head and a uniform temperature distribution in the cylinder head.
