Does your engine have carbon buildup
Back in the days of carburetor-equipped engines and leaded gasoline, a proper engine tune-up included the use of a top engine cleaner to remove the carbon deposits that built up on the intake valves and in the combustion chambers of the engine. Today’s modern fuel-injected engines may go a lot longer between scheduled tune-ups than a vintage carburetor-equipped engine, but engine decarbonization should still be part of your scheduled vehicle maintenance program. That’s because the gasoline the engine uses to make power during the combustion process is still causing power-robbing deposits to build up in your engine.
The air flow from the PCV (positive crankcase ventilation) system and EGR (exhaust gas recirculation) valves will also cause fuel- and carbon-related deposits to build up on the intake valves, which will restrict the airflow into the engine’s cylinders and cause the engine performance to diminish. The combustion process will also cause carbon deposits to build up in the combustion chamber that will negatively affect the combustion process and increase the engine’s need for higher-octane gasoline.
The carbon deposits that form on the top of the piston and in the combustion chamber will increase an engine’s need for high-octane gasoline because the deposits will artificially increase the heat in the engine’s combustion chamber. The carbon deposits that form on the intake valves both restrict the flow of the air/fuel mixture into the cylinders and negatively effect fuel vaporization. If the fuel is not fully vaporized and properly mixed with the air in the engine’s cylinders during the combustion process, part of this fuel may go out of the cylinders as unburned hydrocarbons. These unburned hydrocarbons can cause an engine to fail a smog check because the unburned hydrocarbon (HC) content in the exhaust may exceed the emission test standards. These carbon deposits can also cause cold start and driveability problems as the engine warms up because they can actually act as a sponge by momentarily absorbing some of the fuel that is need for proper combustion.
