    An in-line multicylinder internal combustion engine comprising an engine block including a cylinder crank housing having disposed therein a plurality of approximately horizontally disposed cylinders and a cylinder head mounted on the cylinder crank housing. An approximately horizontally disposed crankshaft is disposed in the cylinder crank housing for reciprocably displacing pistons in the respective cylinders, and an exhaust system is provided which begins at an underside of the cylinder head. A first housing cover is disposed on the cylinder head and extends in a longitudinal direction of the crankshaft with a second cover being disposed on the cylinder crank housing in an area of the crankshaft and extenging in a longitudinal direction thereof. The first and second housing covers each have essentially smooth lateral outer housing walls, with a cooling arrangement being mounted above an upper forward edge of the engine block. At least one first auxiliary unit for the engine is disposed on top of the engine block behind the cooling arrangement and a housing part is connected to and disposed below the cylinder crank housing. At least one second auxiliary unit for the engine is accommodated by the housing part. A part of the exhaust gas system extends next to the housing part with such part of the exhaust gas system being shaped as a housing member.

    The invention relates to mechanical engineering, in particular to internal combustion engines, namely to multi-engine 4 motorcycle internal combustion engines. The aim of the invention is to improve the overall weight indicators and reduce noise. FIG. 1 shows an internal combustion engine with auxiliary units and a switchable gearbox docked to the flange in the form of a propulsion unit ready for installation ;, FIG. 2 is a view along arrow A in FIG. 1 (without intake system); in fig. 3 is a view along arrow, B in FIG. I; in fig. 4 is a diagram of the drive of an internal combustion engine with shafts unrolled in one plane; in f. 5 is a diagram of the drive mechanism of an internal combustion engine, end view, corresponding to FIG. 3; in fig. 6 is a sectional view BB in FIG. 3 {without transmission); in fig. 7 a section of YYY in FIG. 6; FIG. 8 is a section DD-D in FIG. 6. / The engine of internal combustion 1 is equipped with a switchable 2-gear transmission docked to the flange and has at the front and rear extreme points one node 3 for the suspension on the frame of the motorcycle (not shown). The internal combustion engine I consists of a block of 4 cylinders, a head of 5 cylinders and a crankcase 6 attached to the block of 4 cylinders from the bottom of the crankcase 6 Together with the covers 7 and 8 located on both sides, the front control cover 9 and the rear flange cover 10 no internal combustion I (Fig. 1-3). The cylinder block 4 contains three horizontally arranged cylinders; 11, in which the pistons 12 are driven by the crankshaft 13 by connecting rods 14 and which have a cylinder cooling jacket 15 for liquid cooling. Head 5 TSH1INDROV contain-1t for each cylinder 11 a pair of inlet and outlet valves 16 and I7 to control the inlet and exhaust channels 18 and 19. Dp this cylinder head 5 contains in its valve chamber 20, a closed cap B, valve control parts 16 and 17, namely the rylism coil 212 driven by a cam camshaft 22. The cylinder head 5 also includes cooling channels that form the cylinder cooling cylinder 23 and are connected to the cylinder cooling jacket 15. Dp coolant transmission from the pump 24, located on the front side, in its housing, control cock 9 and cylinder head 5 are made channels 25 and 26 for circulating coolant. Next to the pump 24 on the crankcase 6, the oil filter housing 27 is also located on the front side. The bottom of the crankcase 6 is embodied as a removable ribbed oil bath 28. To return the lubricant from the rotational zone of the crankshaft I3 to the oil bath 28 in the cylinder block 4, a slit-shaped oil drain 29 with a wiper edge 30 is made parallel to the bottom edge of the crankcase housing 7 7. Sideways, adjacent to the crankcase 6 and the oil bath 28, to the bottom of the cylinder head 5 and the outlet channel 19 leaving there is adjacent an outlet device 31 having a profile 6, the lateral appearance of which is for symmetry has a profile that repeats — the outer contour of the opposed crankcase 6 and the oil bath 28. The outer contours on both sides continue, furthermore, in the caps 7 and 8, which also have the same profiles, so that together there is a matching or mirror-like external contour of the engine internal combustion on both sides. The upper part of the internal combustion engine 1 carries the main part of the auxiliary units. Thus, carburetors 33 are attached to and fixed to the inlet channels 18 of the cylinder head 5 by means of the inlet lines 32 (see FIG. 1). On the upper side of the cylinder head 5 there is a thermostat housing 34 with fittings 35 for connecting pipes 36 and 37 to the radiator 38. The radiator 38 adjoins the upper front edge of the internal combustion engine 1 also on its upper side. It is somewhat deviated from the engine, which is consistent with the same inclination of the frame 39 of the motorcycle, which
    31
    connects to attachment points 3, iJ width radiator 38 extends approximately the entire width of the internal combustion engine 1, and height approximately to the height located on the upper side of the engine of internal combustion 1 of carburetors 33 as the most prominent auxiliary units. When mounted on a motorcycle, radiator 38 can reach to the area of the steering head (not shown). Between radiator 38 and carburetors 33 there is a fan 40, as well as cooling air deflector 41, which removes the heated air from radiator 38, so as not to adversely affect the auxiliary units located behind (Fig. 1).
    On the upper side of the internal combustion engine 1 are the remaining auxiliary units of the ignition device 42 and the starter 43 (Fig. 1-3). The latter, to save space, is partially located in the thread-like recess 44, bounded by the walls of the cylinder block 4 and the cylinder head 5. Starter 43 is fixed on the flange wall 45, made on the rear upper edge of the cylinder block 4. A rear flange cover 10 adjoins the flange wall 45, which carries an electric generator 46 that is offset from the stater 43 and protrudes rearward. It is also partly located in the upper recess 47 of the box housing 2 gears to save space. Above the generator 46 there is an air filter and an intake silencer 48, which is connected to the carburetors 33 by a pipe 49..
    The internal structure of the internal combustion engine I is shown in FIG. 4 and 5. The crankshaft 13, through a chain or toothed belt 50, transmits rotation to the cam-type distributor shaft 22. This drive is located inside the front steering wheel 9 of the control (FIG. 1-3). Opposite it, in the cylinder head 5, exhaust ventilation casing 51 is located and is partially complete as one with the rear
    174
    flange cover 10 (Fig. 7). Crankshaft . 13 At its end, on the transmission side, bears a cylindrical gear 52, with which gear 5S engages with a ratio of 1: 1 and gear 54 with a transmission ratio of 1.5: 1. Through these gears 53 and 54 is actuated, on the one hand, auxiliary shaft 55 and, on the other hand, auxiliary shaft 56 with a direction of rotation opposite to the direction of rotation of the crankshaft 13. Auxiliary shaft 55 carries weights 57 to compensate for mass moments due to the three-cylinder design, rotated to box 2 reruns not gear 53 — power takeoff flange 58 for the drive connection to the 2-speed gearbox, and at the opposite end the driven gear 59 of the cylindrical gear for the shaft 60 of the pump 24. It carries, at one end as an integral part of the cylindrical gear, the drive gear 61, on the other The end of the impeller 62 of the coolant pump 24 and coaxially between its two bearings is one of the two gears 63 and 64 of the oil pump.
    The auxiliary shaft 56 at its end on the drive side of the cam camshaft 22 has a bearing 65, an angular gear drive gear 66 with a ratio of 1: 3 for the ignition device 42, made in the form of a triple ignition distributor. On the other side of the gear 54, fixed on the auxiliary shaft 56 outside the second bearing 67, the auxiliary shaft 56 carries at the extension 68 on the drive side a gear ring 69 of the starter for coupling to the gear 70 of the starter. A firing pulse sensor 71, which is located radially to the starter crown 69, for example interacts with the teeth of the starter ring 69. Further, with the starter ring 69 of the starter is coupled to the electric generator 46 by means of the friction clutch 72.
