CDTI stands for Common Rail Diesel Turbo Injection, which refers to a type of fuel injection system used in diesel engines. This system uses a common rail to deliver fuel to the injectors at high pressure, resulting in better fuel efficiency and lower emissions. On the other hand, Turbo refers to a turbocharger, which is a device that increases the efficiency and power output of an engine by forcing extra air into the combustion chamber. This allows the engine to burn more fuel and produce more power. While CDTI is a fuel injection system, Turbo is a device that increases the air intake of an engine. **
