When a car which is fine on CNG and hesitates or miss on petrol. Show lack of power or becomes jerky and uneconomical, it either has a leaning fuel pump which is not providing desired fuel pressure or has clogged fuel injectors. A slack fuel pump can not be repaired therefore replacement is the only solution but the performance of fuel injectors can be restored completely.
Our mechanics and even the users know only one method for cleaning fuel injectors that is pouring fuel additive to the tank. Additives only make partial cleaning and have many hazards associated with them. When poured in the tank, they come in contact with many such parts of the fuel system and engine which they are not friendly with.
In the advanced countries injector clogging problem is dealt with ultrasonic cleaning. Ultrasonic cleaning has capability to clean stubborn debris from microscopic grooves, cracks and holes. Since the fuel injectors have tiny nozzles which are designed to atomize the fuel, they are almost impossible to clear with any other mean. Only 8% to 10 % clogging in the nozzle can cause an injector to malfunction. Ultrasonic cleaning is internationally accepted most effective process for cleaning fuel injectors. It is cheap and comprehensive solution for the problem.
