Piston Having Combustion Bowl Shaped To Balance Combustion Efficiency And Emission Properties |
摘要 |
A piston for a compression ignition internal combustion engine includes a piston body having a combustion face defining a combustion bowl, and the combustion face including a compound bowl surface and a compound rim surface. The combustion face is profiled to balance a combustion efficiency property of the piston with emissions properties of the piston. A ratio of a diameter of the combustion bowl to a diameter of the cylinder bowl bore is from 0.68 to 0.74. Other dimensional and proportional features of the piston support low smoke and NOx production during operation.
