SPARK PLUG SD-49SMM - DESCRIPTION AND OPERATION 

 
1. GENERAL 

The spark plug together with the magneto and high-tension cables is intended to Ignite fuel-air mixture in 

the engine cylinder. 

 
2. DESCRIPTION 

 

2.1. CONSTRUCTION 

 
The spark plug (Ref. Fig. 1) is a non-detachable, shielded ceramic insulator device. 
The working part of the spark plug has central electrode (l) and side electrode (2). Electric discharge jumps 

spark gap A of the spark plug through the air gap between the central and side electrodes. Damping resistor (3) 
connected in series to the central electrode and arranged inside the spark plug is intended to decrease electrode 
erosion and diminish ignition system radio interference, 

Contact head (4) is insulated from shell (5) of the spark plug with ceramic tube (6). 
The spark plug ahell has a hexagon for wrench S = 22 mm and two threads. Thread B, dia. M14x1.25» is 

intended to screw the spark plug into the engine cylinder hole with the use of copper-asbestos sealing ring (7). 

Thread C, dia. M18x1, is intended to connect a high-tension cable. 
2.2. SPEC

IF

ICATIO

N

S 

Damping resistance at a temperature of (25±10) °C, 
pressure of 1,0 kgf/cm  and relative humidity of (65±15) % ...... From 10,000 up to 

1000 ohms 

The spark plugs should be tight. 
Seepage at a pressure difference of 40 kgf/cm  is allowed………. Not more than 1 cm3

 

during 30 s 

Spark generation should be at a pressure of surrounding air 
equal to 10 kgf/cm………………………………………………………Continuous 
Spark plug mass ...............................................  …………………... Up to 0.095 kg.
