In addition to using technology GDI gasoline direct injection, the engine of Q3 are combined with turbocharging Turbochager help increase engine power, reduce 15% more for fuel consumption and cleaner emissions than the electronic fuel injection engine. Because the material used as pistons and cylinders must be durable (due to the heat generated during combustion is much higher) and also made more complex nozzle increases costs, so this is an important reason that electronic fuel injection system directly GDI is not common as electronic fuel injection EFI.
