TDI vs SDI

The major difference between TDI or SDI is in the way that they aspirate the gas into the combustion chamber. TDI engines come with an exhaust gas turboturbine, which increases the intake of air into the combustion chamber. SDI engines are required to manually aspirate oxygen. These engines are mostly sold in Europe. However, some American manufacturers also produce them. You can read more about TDI and SDI engine here!
