Turbo Direct Injection (TDI) is the technology used for modern Diesel engines produced by Volkswagen Group, and is widely used in passenger cars produced by the company .The engine uses direct injection where a fuel injector sprays directly into the engine cylinder rather than the pre-combustion chamber prevalent in older diesels which used indirect injection. The engine is coupled with a turbocharger and intercooler to increase the amount of air that can get into the engine cylinders, thereby increasing the amount of fuel that can be injected and combusted. In combination, these allow for greater engine performance while also decreasing harmful emissions.The reduced material volume of the direct injection diesel engine reduces heat losses and thereby increases engine efficiency, at the expense of increased combustion noise. A direct injection engine is also easier to start when cold, due to the reduced heat loss of the design.
