摘要

在一台JL368Q

汽油机上分别燃用汽油和M10(甲醇、汽油体积比为1:9)甲醇汽油混合燃料

并利用气相色谱仪(氦离子化检测器)实验研究了甲醇和甲醛的排放特性及点火提前角对醇、醛排放的影响.结果表明

甲醇排放来源于燃油

其受最高燃烧温度影响较大

该排放将随着发动机转速和排气温度的升高而降低.甲醛由碳氢和甲醇在排气管中经氧化而生成

其排放量随着发动机转速和排气温度的提高而增加.汽油机的甲醛排放量随着转矩的增大先增后减

在中、高负荷时

M10发动机甲醛排放量为汽油机的1.5～4.5倍

随着发动机转速的提高

这2种负荷下的甲醛排放量差距减小.

Abstract

The characteristics and the effects of ignition timing on methanol(CH

OH)and formaldehyde(HCHO)emissions of a spark ignition(SI)engine fueled with gasoline and M10(10% of methanol in blend by volume)blend respectively were experimentally investigated with gas chromatography(equipped with a helium ionization detector

HID). Results show that

OH emission was the unburnt part of fuel methanol

and it was greatly affected by the maximum in-cylinder temperature and decreased with engine speed and exhaust temperature while HCHO emission increased with them. HCHO was mainly formed in the exhaust pipe. HCHO emission from the gasoline engine increased first and then decreased with the increase in the engine torque. In addition

at middle and high engine load

HCHO emission from the M10 engine was 1.5-4.5 times that from the gasoline engine

and

their HCHO emissions were close at high engine speeds.
