DEVICE FOR OBTAINING COMPRESSED AIR USING CYLINDER OF INTERNAL COMBUSTION ENGINE Russian patent published in 1996 - IPC

FIELD: engine engineering. SUBSTANCE: device has control valve 1 positioned on the engine cylinder and provided with a solenoid drive. An electric circuit is used to switch the cylinder for operation as a compressor or engine. The fuel injection stops with a plunger pair or rotatable gate. To increases the time period during which solenoid drive 6 actuates control valve 1, a capacitor is connected in parallel to the coil. The capacitor controls the temperature of control valve 1. Delivery valve 4 of the device is provided with heat relay 12. To obtain compressed air, the suction and compression strokes are used when the cylinder operates as a compressor. EFFECT: enhanced efficiency. 3 cl, 3 dwg
