This system allows for higher-precision fuel delivery using electronically controlled fuel injectors and higher injection pressure, theoretically leading to better fuel atomization, better air/fuel ratio control, and by extension, better control of emissions. [63] [64] [3] [4] [65]
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).
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).
Multi-point electronic indirect fuel injection with three intake manifold-sited fuel injectors with natural aspiration, and direct injection for the TSI DIN-rated motive power & torque outputs 44 kW (60 PS; 59 bhp) at 5,000–6,000 rpm; 95 N⋅m (70 lb⋅ft) at 3,000–4,300 rpm (CHYA)
Since fuel is directly injected inside the combustion chamber, it never gets a chance to wash any contaminants behind the valves. This results in excessive carbon build up over time, hindering performance. Some engines (like Toyota's Dynamic Force engines) combine direct injection with traditional multi port fuel injection to ameliorate this ...
To avoid carbon monoxide poisoning in your vehicle, the CDC recommends having your exhaust system checked every year, as even a small exhaust leak results in CO buildup inside a car or truck. If ...
