Posted by Jess Stoeckeler on

 

It's Feature Friday! We are back with our continued series about the, 'Top 10 Changes to Stop/Start Vehicles.' This is the 8th installment of a 10-part series.

Part 8: The Engine

‘With improved engine position sensors and gasoline direct injection, the ECM is able to do a neat trick. Since the system knows the position of the piston and valves, it can use the fuel injector and spark plug in the cylinder to “nudge” the engine over to make life easier for the starter. The system will look for cylinders that are on a downward stroke. When the engine needs to start, a small amount of fuel will be injected and ignited to get the engine moving.’
