How does the ECM work to increase horsepower?
The ECM does this by cutting the fuel to the injectors to lower engine to a safer operating speed. Usually the ECM does this at the redline or a few hundred RPMs over the redline. In an automatic transmission the vehicle will upshift to higher gear automatically before redlining.
How are piston rings replaced in a car?
Replacement Cost. Since the piston rings are inside of your engine, this means an auto mechanic will need to remove the engine from your vehicle and disassemble it so they can access the worn-out piston rings. After they replace the piston rings, they must reassemble the engine and install it back into your vehicle.
When do you blow by the piston rings?
Blow by is when the air oil mixture in the combustion chamber escapes past the piston rings and creates a positive pressure in the crankcase. This pressure is vented from the positive crankcase ventilation (PCV) hose back into the intake. When there is a large amount of blow by, you may notice your intake is quite oily.
What are the symptoms of a bad piston ring?

How are pistons used in a combustion engine?
Most combustion engines have pistons. Pistons, along with the closed valves in the head, are used to seal the combustion chamber while the air fuel mixture is igniting on the combustion stroke. As the air fuel mixture ignites, it forces the piston down the cylinder bore.
