Effect of gasoline additive on combustion and emission characteristics of an n-butanol Partially Premixed Compression Ignition engine under different parameters

Abstract The experiments were conducted on a modified two-cylinder diesel engine to investigate the effects of excess-air coefficient (λ) and intake temperature (T in ) of different blending ratios (volume ratio of gasoline in the blends) on the combustion and emission characteristics of a Partially...
