In modern systems, the distributor is omitted and ignition is instead electronically controlled. Much smaller coils are used with one coil for each spark plug or one coil serving two spark plugs (for example two coils in a four-cylinder engine, or three coils in a six-cylinder engine). A large ignition coil puts out about 40 kV, and a small one such as from a lawn mower puts out about 15 kV.

These coils may be remotely mounted or they may be placed on top of the spark plug, known as direct ignition (DI) or coil-on-plug. Where one coil serves two spark plugs (in two cylinders), it is through the wasted spark system.

In this arrangement, the coil generates two sparks per cycle to both cylinders. The fuel in the cylinder that is nearing the end of its compression stroke is ignited, whereas the spark in its companion that is nearing the end of its exhaust stroke has no effect.

The wasted spark system is more reliable than a single coil system with a distributor and less expensive than coil-on-plug.

Where coils are individually applied per cylinder, they may all be contained in a single molded block with multiple high-tension terminals. This is commonly called a coil-pack.

A bad coil pack may cause a misfire, bad fuel consumption or loss of power.

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: 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.
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
