دلراسة تأثير نسبة وقود الديزل في وقود ثنائي على أداء محرك اشتعال بالانضغاط

Abstract EN

The aim of this work is to study the effect of diesel fuel percentage on the combustion processes in compression ignition engine using dual – fuel (diesel and LPG).

The brake thermal efficiency increased with the increase of diesel fuel rate at low loads, and decreased when load increased.

To get sufficient operation in engine fueled with dual fuel, it required sufficient flow rate of diesel fuel, if the engine fueled with insufficient diesel fuel erratic operation with miss fire cycles presented.

Dual-fuel operation at part load showed higher specific fuel consumption than straight diesl operation.

At full loads, brake specific fuel consumption of duel fuel engine approaches that for diesel fuel values.
