Improving fuel economy or gaining horsepower means making the engine more efficient. Fuel economy or maximum power is only obtainable when the correct air/fuel mixture or ratio (a richer mixture for ...

Ignition timing is easily the single most important tuning adjustment on an internal combustion engine and yet the concept of ignition curves continues to be elusive for many enthusiasts. Yet all it ...

How to increase horsepower through ignition timing. How does ignition timing affect horsepower? Should an engine advance or retard timing to increase horsepower? This video explains the logic behind ...

"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 ...

According to NGK, adding 10 degrees of ignition timing at idle will raise the spark plug temperature anywhere from 180- to 210 degrees Fahrenheit. This means that adding just one degree of ignition ...

The ignition control module is a crucial component of a vehicle's ignition system. It is a control unit responsible for regulating the ignition timing and generating sparks to ignite the fuel-air ...

underway before tdc is reached. This gives a maximum cylinder pressure (and work output). This ignition timingcondition is about 20 degrees of crank rotation before tdc, i.e. 20 degrees btdc. From, ...

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 ...
