Abstract:Based on a 11 L heavy-duty diesel engine which can meet China Ⅵ b emission standards, by using pure diesel, 85% diesel+15% butanol, and 70% diesel+30% butanol by volume, the effects of fuel properties and coolant temperatures on cycle variation were studied. The results showed that there are no clear laws on the effects of adding different proportions of n-butanlol on cycle variation. The effect of fuel properties on cycle variation is complex, and may be random. With coolant temperature increasing, cycle variation decreases,especially at low loads. High coolant temperature is more suitable for low cetane fuel at low loads.
