Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
The R8 is powered by a 3.6 L Audi V8 with Fuel Stratified Injection (FSI), which is a variation on the concept of gasoline direct injection developed by VW; it maximizes both power and fuel economy at the same time.
It features some of the latest engine technology such as direct fuel injection, sintered camshaft lobes, thin-walled engine block, variable valve timing and lift for intake and exhaust valves, downstream oxygen sensors, exhaust manifold integrated into the cylinder head, exhaust gas recirculation and cooling, distributors coil-on-plug ignition ...
Low-speed pre-ignition (LSPI), also known as stochastic pre-ignition (SPI), [1] is a pre-ignition event that occurs in gasoline vehicle engines when there is a premature ignition of the main fuel charge. [2] LSPI is most common in certain turbocharged direct-injection vehicles operating in low-speed and high-load driving conditions. [3]
The Audi RC8 2.0 TFSI is a prototype four-stroke 2.0-litre single-turbocharged inline-4 gasoline racing engine, developed and produced by Audi Sport GmbH for Deutsche Tourenwagen Masters. The RC8 2.0 TFSI engine is full custom-built but partially borrows the cylinder blocks from Volkswagen-Audi EA888 2.0 R4 16v TSI/TFSI road car engine which ...
when paired with direct injection and enhanced transmission ratio, the TVS supercharger helps the engine achieve 290 hp with an average fuel economy of nearly 24 miles per gallon Parks, Jim (6 November 2008).

The R8 is powered by a 3.6 L Audi V8 with Fuel Stratified Injection (FSI), which is a variation on the concept of gasoline direct injection developed by VW; it maximizes both power and fuel economy at the same time.
It is related (through several evolutions of engine families) to the EA827 series, indirect-injection diesels, 16 valves, and five-cylinder gasoline engines. Naturally aspirated direct-injection variants are known as Suction Diesel Injection, abbreviated to SDI. Many are offered with a turbocharger, and known as Turbocharged Direct Injection (TDI).
