Description

bougie-allumageAlthough the spark plug made its debut in 1876, is was not until 1902, when motor vehicles were in full swing, that manufacturers such as Robert Bosch began to actually manufacture them.
A spark plug makes a gasoline engine work by producing a spark which ignites the air/fuel mixture in the motor once per power stroke and, thus, makes the engine run.
It is located above the cylinder and can be found in all contemporary gasoline engines.

The current travels through the ignition coils to the terminal nut and creates a spark between the platinum plate, a.k.a. iridium, and the side electrode while passing through various conductors.

Problems that arise

The plugs become clogged with build-up due to combustion and miles of travel. Over time, the plugs produce a spark of lesser quality which affects motor efficiency and keeps the air/fuel mixture from igniting properly.

The most commonly occurring problems include:

  • Precarious slow motion
  • Lags in acceleration
  • A lack of power
  • Engine wheezing
  • Problems starting the engine

The best solution

Hydrogen has a descaling effect which helps eliminate impurities that have built up in spark plugs over time and after many miles of travel. This process makes for a stronger spark which, in turn, improves the mixture’s combustion. You will still need to remember to replace the spark plugs eventually since they have limited durability. Automotive manufacturers outline this in their “Manufacturer’s Recommendations.”
