Here's why:
* Direct Injection: The fuel is injected directly into the combustion chamber, unlike indirect injection systems where fuel is first injected into a pre-chamber and then enters the combustion chamber.
* Combustion Chamber Location: The injector is physically positioned within the combustion chamber itself.
This design offers several advantages:
* Higher efficiency: Direct injection allows for more precise control of fuel injection, leading to better combustion and higher efficiency.
* Lower emissions: The precise injection helps reduce emissions, particularly soot and NOx.
* Better power: Direct injection systems can achieve higher compression ratios, leading to more power.
However, direct injection engines can also have some disadvantages:
* Higher noise: The direct injection process can lead to increased engine noise.
* More complex: The system itself can be more complex and expensive compared to indirect injection.
