摘要

为了实现甲醇/柴油双燃料发动机的高热效率和低排放

在一台单缸柴油机上搭建了独立的双直喷系统

开展了甲醇/柴油双直喷发动机运行范围的试验研究。结果表明:在低负荷率工况下

随着甲醇替代率的增加

发动机热效率降低; 在中、高负荷率工况下

甲醇的加入有利于提高发动机热效率。在负荷率为79.5%、甲醇替代率为52.4%的工况下

发动机指示热效率达到最大值(43.4%)。同时

随着甲醇替代率的增加

发动机NO

和碳烟排放降低

而HC和CO排放呈现出增加的趋势。此外

在全负荷工况下

探究了最大甲醇替代率及其对发动机热效率的影响

发现双直喷发动机的最大甲醇替代率可以达到96.0%。随着甲醇替代率的增加

发动机指示热效率呈现出先提高后降低的趋势

最高指示热效率发生在甲醇替代率为50.0%的工况下。该研究结果可为甲醇/柴油双直喷发动机性能和排放特性的进一步优化提供试验和数据支持。

Abstract

In order to achieve higher thermal efficiency and lower emissions of methanol/diesel dual-fuel engines

an independent dual-direct injection system was built on a single-cylinder diesel engine and the operating range of the methanol/diesel dual-direct injection engine was conducted experimentally. Results show that the indicated thermal efficiency decreases with the increase of the methanol energy substitution ratio under low engine loads. But the increase of the methanol energy substitution ratio benefits the improvement of indicated thermal efficiency under medium and high engine loads. The

highest indicated thermal efficiency of 43.4% could be achieved at an engine load rate of 79.5% and a methanol energy substitution ratio of 52.4%. Meanwhile

with the increase of the methanol energy substitution ratio

and soot emissions decrease

but the opposite trends of HC and CO emissions are observed. Besides

the maximum methanol energy substitution ratio and its influence on the thermal efficiency of the engine were investigated under the full engine load and it was found that the maximum methanol energy substitution ratio of the dual-direct injection engine could reach up to 96.0% and the indicated thermal efficiency first increases and then decreases with the increase of the methanol energy substitution ratio and reaches a peak when the ratio increases to 50.0%. The research can provide experimental and data support for further optimization of the performance and emission characteristics of methanol/diesel dual-direct injection engines.
