The lack of clearly identified constraints for ignition and flame propagation has hindered understanding the processes which limit lean operation in spark ignition engines. This experimental study ...

Ignition coils last far longer than spark plugs and only need replacement when symptoms appear. Here’s how to tell if coils ...

As long as the internal combustion engine has existed, engineers have been trying to find better ways of igniting the highly combustable mixture of air and gasoline that powers cars. Everything from ...

SAE International Journal of Engines, Vol. 14, No. 3 (2021), pp. 335-344 (10 pages) The addition of a spark plug in place of the original fuel injector and fumigating natural gas (NG) inside the ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

While most engines have the same number of spark plugs and cylinders, some four-cylinder blocks have two plugs for each ...

What many consider the Holy Grail of combustion technology is one step closer to prime time. In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM ...

A few years ago sparkless ignition or homogeneous charge compression ignition (HCCI) in gasoline engines was all the rage, with a number of major automakers including General Motors, Daimler and ...
