If you're a follower of the "How It Works" series, you've been learning the principles of what makes a car run. You've boned up on the four-stroke cycle, valvetrains, cooling, lubrication, and ...

At 7,000 rpm, a spark plug ignites the air/fuel mixture nearly 60 times per second. Any one of those 60 sparks going amiss can at best be mildly annoying, and at worst cost you a race or an engine.

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 ignition coils in your car provide the high voltage electrical current that allows your spark plug to create its spark. These parts are humble looking, and they make use of relatively simple ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

What’s the fastest way to a mental breakdown in your garage, and why is it an ignition issue? No doubt, that stress headache comes on strong when your car was running a minute ago, whereas now it’s ...

"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...
