Internal combustion engines are likely to remain in widespread use for some time yet, but it's possible that we may be bidding adieu to that most iconic of engine parts, the spark plug. Researchers ...

In conventional engines, spark plugs send high-voltage electricity sparking across the electrode gaps in a combustion engine: This results in a controlled explosion in the engine, which drives the ...

You're hunched over the engine with your wrist painfully contorted, wishing you were Mr. Fantastic. You've finally removed broken spark plug number four and then the intrusive thought hits. "Should I ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...

One of the main differences in regular maintenance between a gasoline and a diesel-powered car is replacing the spark plugs. While diesel engines rely on compression to create ignition, and thus ...

A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

Just like spark plugs, ignition coils can wear down and become faulty over time. There are many common signs that an ignition coil is getting bad, but one obvious sign is an engine misfire, typically ...

The pollutant emissions and high-energy consumption of combustion engines using conventional spark plugs have long been serious environmental problems. Now, it has been demonstrated that lasers can ...

When you boil it down, improving average fuel economy is super simple: Burn less fuel in the cylinder when cruising. Toward that end, engine developers have toiled to make lean mixtures work since way ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...

In this age of electronic fuel injection and ignition it’s hard to believe there are still some running around with a points-trigged ignition system. The concept of breaker-points ignition is all ...
