    A V-shaped, air-cooled engine is provided with a cover on the front thereof, which houses a cooling fan connected to the engine's crankshaft. The interior of the cover is fitted with dividers to separate the air flow and direct it to the opposite sides of the engine, and to form a compartment for housing components of a non-contact ignition system. The non-contact ignition system is operated by the cooling fan, and is cooled by the flow of air through the cover. Components of the ignition system are permanently connected to each other, without the usual separable connectors.

    1 The invention relates to internal combustion piston engines, and in particular to engine components therein, to protect against damage to the ignition system. An air cooled internal combustion engine with Y-shaped cylinders is known, equipped with a contactless ignition system and containing a crankcase with cylinders that are installed on opposite sides of the crankcase and provided with cooling fins. At the front end of the crankcase is attached to the stove plate. The crankshaft shaft is fixed for rotation in the crankcase; its front end projects forward and the flywheel-fan is fixed on it. Attached to the mounting plate is a flap that covers the flywheel-fan, which has an inlet on the front wall, a cavity, and two outlet slots on the rear wall of the rivets for air passage along the cooling fins of the cylinders. The engine contains a contactless ignition system, which includes plugs and ignition coils for each cylinder, a non-contact unit, an ignition generator and a pulse generator, equipped with corresponding non-rotating coils and a rotating magnetic core mounted on the flywheel-fan. A disadvantage of the known construction is increased complexity caused by a large number of connectors and electrical connections for mounting on the engine of the ignition system, as well as a large number of seals in places of passage of wires in the protective elements of the engine The purpose of the invention is to simplify the design of the internal combustion engine. The goal is achieved by the fact that in the engine; e internal cooling air with another cooling and a contactless ignition system containing a crankcase with V-shaped cylinders fitted with cooling fins, the mounting one fixed at the front end of the crankcase is located in the crankcase with a crankshaft, the front end is cottocc-o P2 protrudes from the mounting plate and on not) .1 a flywheel-fan is installed, a cover attached to the mounting plate and covering the flywheel-fan, and the key has an inlet on the front wall, a cavity and Va located on the rear wall of the outlet - one on each side of the crankcase to pass air through the cooling fins of the respective cylinders, and a contactless ignition system, including a spark plug and an ignition coil for each cylinder, a contactless control unit, as well as an ignition generator and a pulse generator, fitted with corresponding non-rotating coils and a rotating steel magnetic core fixed to the flywheel-fan, the cover is provided with a partition wall forming in the cavity of the roof are two chambers in communication with the corresponding outlets, and a compartment, inside which are placed the ignition coils and a contactless control unit, the front wall of the lid having curvilinear portions forming the upper outer corners for directing the cooling air from the chambers through the corresponding outlets, and vertical the part located above the partition, and forming the front wall of the compartment, the ignition generator's coil being placed inside the handwheel-fan, and the impulse coils waist-flywheel generator outside fan. The inlet can be made in the central part of the front wall of the cover and provided with anti-dust filtering means. A gap is provided between the walls of the cover and the cooling fins of the respective cylinders for the flow of cooling air. 1 In FIG. 1 shows the e: electric circuit of the contactless ignition system 5 in FIG. 2 is an engine with a partial cut across the rat in FIG. A section A-A in FIG. 2, in FIG. 4 is a top view of the engine in FIG. 5 the same, in axonometry. The engine contains a crankcase 1 with cylinders 2 and 3 arranged in a manner that are provided with guard ribs 4. At the end of the HeM end, crankcase 6 is fixed to the crankcase 1. A crankshaft 7 is installed in the crankcase 1 with rotation. The front end 8 of the crankshaft 7 protrudes forward from the mounting plate 6 and a flywheel fan 9 is mounted on it. A cover 10 is attached to the mounting plate 6, closing the flywheel-fan 9. On the front wall 11 of the key 11 there is an inlet 12, and on the back wall 13 - outlets 14 and 15 serving for supplying cooling air to cylinders 2 and 3, respectively. The engine is equipped with a contactless ignition system including a spark plug 16 and a coil 17 for each cylinder, a contactless control unit 18 and an ignition generator. A non-rotating coil 19 and a rotating steel magnetic core 20 mounted on a flywheel-fan 9. The ignition system also contains a pulse generator consisting of non-rotating coils 21 and 22 and a core 20. Coils 19, 21 and 22 are fixed on a mounting plate 6, wherein the coil 19 is located inside, and the coils 21 and 22 outside the flywheel-fan 9. The contactless control unit 18 comprises a diode 23, capacitors 24 and 25 and thyristors 26 and 27. The cover 10 is provided with a dividing partition 28 separating the cavity 29 covers 10 on kame s 30 and 31 communicated with the respective discharge apertures 14 and 15. The upper part 10 krshzhi by partitions 28 formed compartment 32, inside which there are ki Katushev 17 and plug 18 blo contactless control. The front wall 11 of the lid 10 has curved sections 33 and 34 in its upper outer corners and a vertical part 35 located above the leregorodka 28 and forming the front wall of the compartment 32. The inlet 12 is closed by a filter element 36. 2 and 3, a gap 37 is provided. The engine operates as follows. The crankshaft 7 rotates the flywheel 9, which drives the contactless ignition system, and also draws cooling air through the inlet 12 in the cover 10 and drives it to cylinders 2 and 3 through chambers 30 and 31 and outlets 14 and 15. Cover 10 is designed to provide optimal flow of cooling air. The curved sections 33 and 34 and the partition wall 28 create the necessary direction of air flow. Compartment 32 is also cooled by this air flow. The chambers 30 and 31 are filled with approximately the same volume, which makes it possible to supply an equal volume of cooling air to the cylinders 2 and 3. The partition wall 28 has a bend that is located at a point between 15 and 45 from the horizontal axis passing through the axis of the crankshaft 7. This bend divides the cavity 29 into chambers 30 and 31. To improve the blowing conditions between the fins 4 of the cylinders 2 and 3 and outlet openings 14 and 15 provide a gap 37. As the steel magnetic core 20 rotates, coil 19 generates an alternating current, which is converted in capacitors 24 and 25. Pulse coils 21 and 22 generate signals that alternate to thyristors 26 and 27 and they are opened, thereby allowing the capacitors 24 and 25 to be discharged through the respective ignition coils 17. When a capacitor is discharged through the ignition coil in a spark plug 16 installed in their circuit, a spark occurs. I The proposed internal combustion engine is simpler known by reducing the number of connectors and electrical connections for mounting on the ignition engine. In this case, there is no need for a whole range of seals in the places of passage through the structural elements of the engine.
