FUEL INJECTORS
Fuel injectors are a key component in delivering the right amount of gasoline to the combustion chamber. Poor fuel injector performance results in hard starts, power loss, rough idling, reduced fuel economy and increased emissions.

Fuel injectors increase fuel efficiency and engine response times by delivering a fine mist of fuel right at the engine’s intake valves. This allows fuel to burn more easily, increasing the engine’s response times while reducing the amount of fuel used.
Port fuel injectors spray fuel in the intake port area where it flows past the intake valve into the combustion chamber.
Direct injectors have the tip positioned directly in the combustion chamber and spray fuel into the combustion chamber, bypassing the intake valve. This design allows the engine to have even better fuel economy.
Carbon deposits can clog fuel injectors, turning the fuel pattern into a stream instead of a mist. As a result, less fuel is delivered to the combustion chamber and the fuel that does enter the chamber burns less efficiently.
Port fuel injectors can be cleaned using a detergent called PIBA (polyisobutylene-amine). But GDI/direct injectors are harder to clean. They require P.E.A. (polyether-amine), a specialized detergent that’s strong enough to survive the heat of a combustion chamber. Check individual product details for detergents used. Port fuel injectors spray fuel in the intake port area where it flows past the intake valve into the combustion chamber. Direct injectors have the tip positioned directly in the combustion chamber and spray fuel into the combustion chamber by-passing the intake valve. This design allows the engine to have even better fuel economy.
Performance Issues
Hard starts, power loss, rough idle, slow acceleration, lower fuel economy, increased emissions.
Solution
Gumout® fuel additives use a variety of detergents to fight carbon buildup in fuel injectors. These detergents bond to carbon particles on injectors and disperse them to restore performance. They also bond to the surface of the nozzle, helping prevent further carbon buildup.
