What is the difference between direct injection and indirect injection?
Expert Solution & Answer
To determine
The difference between direct and indirect injections.
Explanation of Solution
The differences between direct and indirect injections are shown in below table.
| S.No. | Direct injection | Indirect injection |
| 1 | The fuel is directly injected into the cylinder. | The fuel is injected into the cylinder through a pre-chamber by a narrow opening. |
| 2 | The first combustion occurs in the cylinder where the piston experiences a depression. | The first combustion occurs in the pre-chamber. |
| 3 | More efficient and more noise. | Less efficient and less noise. |
