Formerly, ignition coils were made with varnish and paper insulated high-voltage windings, inserted into a drawn-steel can and filled with oil or asphalt for insulation and moisture protection. Coils on modern automobiles are cast in filled epoxy resins which penetrate any voids within the winding.

A modern single-spark system has one coil per spark plug. To prevent premature sparking at the start of the primary pulse, a diode or secondary spark gap is installed in the coil to block the reverse pulse that would otherwise form.

In a coil meant for a wasted spark system, the secondary winding has two terminals isolated from the primary, and each terminal connects to a spark plug. With this system, no extra diode is needed since there would be no fuel-air mixture present at the inactive spark plug.

In a low-inductance coil, fewer primary turns are used, so primary current is higher. This is not compatible with the capacity of mechanical breaker points, so solid-state switching is used.

Q: What kind of production line does Torch have for ignition coils?
A: Torch manufacturing facilities are of modular design suitable for group working and offer maximum flexibility. They can be expanded, scaled down, combined and converted in a short space of time, thus permitting economical and top-quality production of up to 5,000 items a day alternating between large and small series and the various types of ignition coil.
Q: What are the features of Torch ignition coils?
A: There are four outstanding features of Takumi igntion coils: High-precision ignition componentsCustomer-specific developments and system integration Rational computer-controlled manufacturing techniques High-tech quality based on zero-defect programmes.
Q: What temperature can Torch ignition coils bear?
A: Temperature-resistant: up to 150 °C, brief periods up to 165°C
Q: What voltage can Torch igntion coils undertake?
A: Torch igntion coils can undertake voltage greater than 30 KV
Q: How to judge whether coil need to be replaced or not?
A: Ignition coil troubleshooting begins by disconnecting a spark plug wire and installing an extra spark plug into the end of the wire. Lay the spark plug on a part of the engine where the plug will be resting against a good ground. Turn the engine over by having a helper hold the key in the start position while the spark plug is observed for a good spark.
