- Abstract
The main aim of this paper is to improve the performance and to reduce the emissions of CI engine combustion. Experiments have been conducted on a single cylinder CI engine with normal injection and two pulse injection (split injection). From the simulated results and also existing experimental results it was observed that 10° dwell for double injection gives better results. In the present work, for split injection, existing cam shaft has been replaced with a modified cam shaft with a dwell angle of 10°, and experiments have been carried out with normal camshaft for single injection and with modified cam shaft for double injection. In double injection 50% of the total mass of the fuel was injected in the first pulse and the remaining 50% was injected after a dwell of 10°. Experiments have been carried out for Single Cylinder Diesel Engine with the normal cam shaft which was existing in the engine for different loads (25%, 50%, 75% and 100%). The modified camshaft with double injection was tested with a dwell of 10°. In the first injection 50% of the fuel was injected and remaining fuel was injected after a dwell of 10°. The cycle peak pressure in double injection has been increased by 8% for full load, NOx emission has been reduced by 8.67%, and CO levels were reduced by nearly 30%.
