The Efect of Combustion Chamber Type on DI Diesel Engine Smoke Emission |
| |
| Abstract: | The effect of the type of DI diesel engine combustion charnber upon mixture formation in cylinder liner is analysed. And also discussed is by optimizing combustion chamber design to solve the worse emission problem which occurs if DI engine output is enlarged. The performance of re-entrant, square type and "turbulent step" re-entrant combustions chambers are analysed and comparized with that of toroidal combustion chamber. |
