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 automotive ignition system is an incredibly amazing machine that has evolved for more than 100 years already and continues to evolve as the demand drives the need to develop more efficient engines ...

Direct-injection spark-ignition (DISI) engines have been investigated for many years but only recently have shown promise as a next generation gasoline engine technology. Much of this new enthusiasm ...

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.

Firepower's smarter sparks are generated by this sealed ignition module which contains an integrated circuit (IC) chip known as an EPROM. Each unit's Erasable Programmable Read Only Memory chip is ...

Ignition system technology has taken a number of twists and turns over the past 50 years. Matthew Beecham talks with experts from Delphi and Denso about the latest developments both on the OE and ...

Push-button start may be common today, but it wasn't always the dominant way to crank an engine. Push-button start systems and ignition key systems activate the same process in different ways. Do you ...

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 ...

Out of the many different aspects of the Pontiac hobby, ignition-system function is often the most misunderstood. Since it deals with an intangible (i.e., electricity), it's very easy to assume one ...

As the cost of gasoline rises and environmental concerns about vehicle exhaust attracts more and more attention, the auto industry is accelerating research on development of new power-train systems ...
