A procedure designed to clean the engine’s air intake system, fuel injectors, and combustion chambers to remove accumulated carbon deposits and residue. This service typically involves introducing specialized cleaning solutions into the engine through the air intake or fuel rail, which then dissolve or dislodge the build-up. For example, a technician might connect a cleaning apparatus directly to the fuel rail, bypassing the fuel tank, and circulate a potent solvent through the injectors to restore proper spray patterns.
The undertaking contributes significantly to improved engine performance and fuel efficiency. Over time, deposits hinder the optimal flow of air and fuel, leading to reduced power, rough idling, and increased emissions. By addressing these issues, the procedure helps to restore the engine to its designed operating parameters. Historically, such maintenance was less critical due to different fuel formulations and engine designs; however, modern engines with tighter tolerances and direct injection systems are more susceptible to deposit formation.
