Each injection valve “opens” one at a time right before the cylinder intake. Sequential electronic fuel injection: This is a type of multi-port fuel injection system.This spark pushes the pistons during the power stroke for faster speeds. Spark ignition: An internal combustion engine uses the combustion energy from the air and fuel mixing in the cylinder to ignite a spark from the spark plug.Instead, air comes in the intake manifold while the gasoline is directly injected into the cylinder.
