Analysis and Study of Methanol-containing Diesel in the Accelerating Condition

This paper analyzes the influence of methanol-containing diesel at the accelerating condition on the performance of diesel engine. The more the methanol is, the greater the changes of p Δt and σ Δt , and the worse the dynamic performance is. At the same time the soot emission increases, which mainly generates at the initial stage of fuel acceleration. The emission of NO x goes up after dropping, then slightly decreases and tends to be stable.
