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

SAE Transactions, Vol. 105, Section 3: JOURNAL OF ENGINES (1996), pp. 1249-1259 (11 pages) The performance of an in-cylinder optical combustion intensity sensor is presented. The sensor and associated ...

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 ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

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 ...

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 ...

With stricter emission standards and the rise of electric powertrains, it might seem like the internal-combustion engine's days are numbered. But Engineering Explained host Jason Fenske believes ...
