Fuel injection strategy for four cycle engines |
摘要 |
The invention includes a combustion chamber and an injection strategy for a direct fuel injected internal combustion engine. The combustion chamber is formed with a substantially flat surface to provide a large surface area on which fuel can collect and evaporated. At high loads, fuel is injected into the combustion in two stages. The first stage starts before top-dead center and stops before a prohibited range where smoke is produced. The second stage starts after the prohibited range and stops approximately when the intake valve is at its maximum lift.
