THE EFFICIENCY OF A LAVAL NOZZLE SPARK PLUG
Annotatsiya
Annotation In order to eliminate the shortcomings of the conventional classic spark plug, the spark plugs were improved in 2 ways: by drilling a hole from the outer L-shaped electrode and cutting out the outer L-shaped electrode of a long threaded spark plug and installing the spark plug into the engine through the supports in the form of a Laval nozzle. Spark plugs installed on cars manufactured by Uzavtomotors JSC have passed laboratory and road tests. The effective fuel consumption of the engine operating with a spark plug with a Laval nozzle was 218 g/kWh, which is 1.31 times less than that of a conventional classic spark plug (control). The acceleration time of the car to a speed of 100 km / h was 11.4 seconds, which is 1.21 times less than the control one. The content of carbon monoxide CO in the exhaust gases was 1.86%, which is 2.10 times less than the control.
