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.

2022年8月1日 · A direct injection technology improves the fuel economy by 10-20 percent, but is it reliable? Does a car with a direct-injection cost more to maintain? What are the pros and cons?

2021年4月13日 · Direct injection technology helps optimize gasoline engines so they burn fuel more efficiently, utilizing different manifolds for air and gasoline. Wondering more about how these engines work and the benefits they offer? Keep on reading. What …

2021年10月13日 · Direct injection (DI) is a fuel delivery system common in modern cars with gas and diesel engines. Rather than a fuel/air mixture entering the engine’s cylinders through the intake valves, an injector sprays fuel directly into the …

2024年5月10日 · GDi stands for "gas direct injection" and refers to how the engine injects gas into the cylinders. In any internal combustion engine, fuel is sprayed into the air to create a mixture of fuel...

It's called direct injection, and it refers to how the fuel makes its way inside an engine's controlled-explosion room, better known as a combustion chamber. In a garden-variety gasoline engine with fuel injection, gasoline takes a more roundabout route …

2018年2月26日 · Unlike other types of fuel delivery, which get fuel into the combustion via the intake, direct injection places a high-pressure injector directly into the cylinder head, allowing fuel to be...

2023年3月18日 · Gasoline direct injection is a modern engine technology that provides many benefits over traditional fuel injection systems. GDI improves fuel efficiency, reduces emissions, and provides improved performance.

2018年10月8日 · What direct injection does is put a fuel injector directly into the cylinder. Usually through the cylinder head, right beside the spark plug. Though it can come in from the side of the combustion...

The two most critical differences between a direct injection engine and a standard gasoline engine are how they deliver fuel and how the fuel mixes with incoming air. These basic premises make a tremendous difference in an engine's overall efficiency.
