This article deals with flame rectification as it applies to direct spark ignition (DSI) modules. They are manufactured by a few different companies — Fenwal, Honeywell, Robertshaw, and White Rodgers, ...

Question: I have a 2006 Kia Sedona, and it randomly misfires roughly once for every week of normal driving and once after each carwash. When it happens, I pull over and shut off the car. Then, I turn ...

In conventional engines, spark plugs send high-voltage electricity sparking across the electrode gaps in a combustion engine: This results in a controlled explosion in the engine, which drives the ...

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 ...

Learn how to use dielectric grease on spark plug boots to prevent voltage leaks and corrosion. Follow our guide to protect ...

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 ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

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