To meet these ever increasing regulations manufacturers are employing additional emission controls to the Internal Combustion engines. Simply put, the manufactures are asking the Internal combustion engine to do more things than it was ever designed to do. As a result, the carbon deposit problem has become more frequent and severe, creating a whole new set of problems and challenges.
Many technicians and managers are well aware that severe combustion chamber carbon build up can create significant drive ability issues with today’s engines. It’s all too rare, however, for them to focus on the fact that carbon build up and slowly deteriorating injector performance is a gradual process that not only affects engine performance but fuel economy as well. Despite this info, the vast majority of these potential issues remain unsolved.
