IGNITION PREVENTION REGULATOR

jALA ENGINE FOR INTERNAL COMBUSTION

The invention relates to the structures of internal combustion engines, and specifically to ignition advance controllers for internal combustion engines.

An advanced ignition regulator is known, which contains an aneroid box, a diaphragm with a rod, a return spring and an element for temperature regulation, located between the carburetor and the vacuum regulator C .fg

A disadvantage of the known advanced ignition controller is that the system of temperature and pressure sensors is located between the carburetor and the vacuum regulator, which does not provide js reliability during operation.

The purpose of the invention is to increase the reliability of the controller.

This Objective is achieved by the fact that the ignition advance controller contains 20 aneroid and D1) UY box, a diaphragm with a rod connected to the chopper, a temperature control element and a return

spring. Moreover, the temperature control element is installed directly in the aneroid box and is connected to the diaphragm by means of an elastic element.

The drawing shows the advance controller, a longitudinal section.

Claims (1)

The ignition advance controller for two comprises a housing 1 communicated with the atmosphere through the openings 2, and a breaker 3 attached to the housing. The regulator has a bolt 4 with a fitting 5 for connection with loosening under a carburetor choke (not shown). A diaphragm 6 with a stem 7 is installed between the housing 1 and the lid 4. The lid 4 and the diaphragm 6 are hermetically pressed against the housing 1 by means of a steel rolled ring 8. In the cavity formed by the lid 4 and the diaphragm 6, there is a return spring 9, one end of the pack. .rayusha with a diaphragm 6, and the other end into a bimetallic disk 1O The bimetallic disk 1O rests on the four supports il, specially provided for this purpose on the basis of the cover 4, so that there is a message of the said cavity through the connection 5 with a vacuum under the choke of the carburetor. In the regulator housing 1 there is a balancing spring 12, inside which the stem 7 of the diaphragm 6 passes. The free end of the rod 7 is connected to the movable disk 13 of the chopper 3. The advanced ignition controller for two operates as follows. When the ambient temperature and the engine is running, the deflection of the bimetallic element 10 is equal to O, then the diaphragm 6 is located in the plane of the connector of the housing 1 and the clamp 4 as a result of the same characteristics of the springs 9 and 12. At the same time, the movable disk 13 of the chopper 3 is set to the position installation angle ahead zyzhigani. When the temperature of the air surrounding the engine and the coolant in its system increases, the temperature of the bimetallic disk 10 will increase accordingly, as a result of which it will protrude to the side (dotted lines in the drawing) and take position 14. This causes the diaphragm 6 to bend to the left , adopting position 15 In this case, the rod 7 will turn the movable disk 13 of the chopper 3 in a clockwise direction, reducing the ignition angle. As the ambient temperature decreases, and consequently, the bimetal disc 10, the ignition advance angle increases. The use of the invention makes it possible to regulate the advance angle of the ignition depending on the temperature of the air under the hood of the car, which significantly increases the performance of the carburetor engine and increases its reliability. Claims An ignition advance regulator for an internal combustion engine comprising an aneroid box, a diaphragm with a rod connected to a chopper, a temperature control element and a return spring, characterized in that, in order to improve reliability, the temperature control element is placed in the aneroid box and associated with the diaphragm by means of an elastic element.
