TDCI Full Form is Turbo Diesel Common Rail Injection
TDCI stands for Turbo Diesel Common Rail Injection. It is a direct fuel injection system built around high-pressure fuel rail feeding solenoid valves, as opposed to low-pressure fuel pump feeding unit injectors in modern diesel engines. These fuel injectors have some benefits over the earlier fuel injections. It injects a large number of droplets in smaller areas that provides good consumption. This system is very suitable for road cars in the automobile industry.
