[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower ...

The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

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 ...

State-of-the-art electronic ignition systems can perform more reliably than old-fashioned breaker points systems, supplying the increased spark necessary to reliably fire today's modified engines.

The P0351 code means your engine control module (ECM) has detected a malfunction in the ignition coil “A” primary/secondary circuit, which corresponds to cylinder 1 on most engines. When this circuit ...
