Then slow down or block 2 or the shaft 3, causing the shaft 3 or the unit 2 continue by inertia to rotate relatively slow parts and starts the engine. After running the unit 2 can be fixed relative to the housing 1. 3 C.p. f-crystals, 2 Il. The invention relates to mechanical engineering, in particular in the engine, and in particular to methods of starting of internal combustion engines.There is a method of starting the engine by the accumulation of kinetic energy of the inertial mass due to its scroll starting and cranking the motor output shaft relative to the cylinder block through the use of akkumulirovannaya energy when connecting the inertial mass to the output shaft (application Germany N 3838673, CL F 02 N 5/03, 1990).The disadvantage of the prototype is a large weight due to the presence of additional inertial mass.The aim of the invention is to reduce the weight and ha and cylinder together with the shaft and the flywheel relative to the housing, and the turning of the output shaft relative to the cylinder carry out due to the deceleration of one of the rotating parts.The objective is achieved by the fact that as the inertial mass using a shaft with a flywheel and brake cylinder, or used as inertial mass of the cylinder, and the brake shaft with the flywheel.The aim is achieved in that the cylinder block can after deceleration to fix relative to the body.In Fig. 1 presents a diagram of the system start with the retardation of the cylinder; Fig. 2 - the same, with the retardation of the output shaft.The proposed method is implemented using a system startup, comprising a housing 1 of the motor mounted on it the cylinder block 2, the output shaft 3 fixed to the end of the flywheel 4, the trigger device 5, the braking device 6 and release 7.The method is implemented as follows. Before turning the output shaft 3 during start-up relative to the cylinder block 2, the latter together with the shaft 3 and the flywheel 4 is rotated relative to the housing 1, storing kinetic energy. Resistance to spinning minimal, since the piston does not move otnositel the outstanding parts of the engine brake, resulting in other details, continuing to rotate the stored kinetic energy to turn a relatively slow parts. When this occurs a relative displacement of the pistons in the cylinders with the change in the volume of the combustion chambers, resulting in the start of the engine.In a variant implementation of the method of the brake unit 2 cylinders. When the flywheel 4 to the output shaft 3 continues by inertia to rotate relative to the block 2.In another embodiment, a brake shaft 3 with the flywheel 4, and continues to rotate by inertia relative to the shaft 3 and the housing 1 unit 2 cylinders.After starting the engine stalled item can let go. Then the operation of the engine occurs with the rotation of the block 2 and the shaft 3 in the opposite side with the output from both parts. Or block 2 is attached by clamps 7 relative to the housing 1. Then the power carried by the rotating shaft 3.Thus, with the implementation of the proposed method decreases the weight of the engine due to the use in inertial the start of the regular parts of the engine. The method involves the ability to manually start the engine with a large displacement or large with the STV inertial mass, accumulation of its rotational kinetic energy and use akkumulirovannaya energy for turning the output shaft attached to the end of the flywheel relative to the cylinder, placed on the housing, characterized in that the energy accumulate during the scroll of the cylinder together with the shaft and the flywheel relative to the housing, and the turning of the shaft relative to the cylinder carry out due to the deceleration of one of the rotating parts.2. The method according to p. 1, characterized in that the inertial mass using a shaft with a flywheel and brake cylinder.3. The method according to p. 1, characterized in that the inertial mass using a cylinder and brake shaft with the flywheel.4. The method according to PP.1 and 2, characterized in that the cylinder block after deceleration is fixed relative to the housing.
