How does the electronic spark control module work?

While one sensor alone can detect engine knocks, two or more sensors are often used in an engine. Multiple sensors in different locations allow the Electronic Spark Control to locate the source of the knock with greater accuracy.

What are the functions of a spark plug?

Spark plugs have an insulated center electrode connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder. The spark plug has two primary functions: (1) To ignite the air/fuel mixture.

Where is the spark plug located in a Wankel engine?

A piston engine has a part of the combustion chamber that is always out of reach of the piston; and this zone is where the conventional spark plug is located. A Wankel engine has a permanently varying combustion area; and the spark plug is inevitably swept by the tip seals.

How is a spark plug connected to an ignition coil?

The plug is connected to the high voltage generated by an ignition coil or magneto. As current flows from the coil, a voltage develops between the central and side electrodes.

How is the voltage of a spark plug determined?

Voltage of Automobile Spark Plugs. Secondly, the spark must occur at exactly the right time to ignite the highly compressed air-fuel mixture in the combustion chamber of the engine. The ignition system must be capable of producing as much as 40,000 volts to force the electrical current across the spark plug gap.

How is the spark plug connected to the engine?

The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug’s metal shell is screwed into the engine’s cylinder head and thus electrically grounded.
