武汉理工大学内燃机学英文课件Chapter9 Control of tailpipe emission
A heat-recovery steam generator was erected after a gas-turbine with a duct burner into the district heat centre. After commissioning, the CO emissions were found to be above the acceptable level spec...
Transesterified fuels (biodiesel) from vegetable oils are alternative fuels for diesel engines. They are renewable and offer potential reduction in CO and HC emissions due to higher O2 contents in veg...
Air pollution caused by diesel engine emissions, especially particulate matters and nitric oxides emissions, is one of the biggest problems of current transportation. In the near future the emission o...
Conversion of waste to energy is one of the recent trends in minimising not only the waste disposal but also could be used as an alternate fuel for internal combustion engines. Fuels like wood pyrolys...
There has been a worldwide interest in searching for alternatives to petroleum-derived fuels due to their depletion as well as due to the concern for the environment. Vegetable oils have capability to...
For the present work, a single cylinder diesel engine was modified to work in dual fuel mode. To study the feasibility of using methyl ester of mahua oil as pilot fuel, it was used as pilot fuel and l...
In this paper some results concerning the combined effect of the tumble flow and combustion chamber geometry layout variations on flame front shape and its propagation through homogenous mixture of is...
Use of crop residues as fuel has a long tradition in rural areas of Serbia. Numerous biomass-fueled facilities were built during the 80s. Among those were small facilities for household heating, with ...
Many households in Serbia, using electric thermo-accumulation furnaces for heating, have been forced to find an alternative solution, due to a significant increase in electricity prices during the las...
The growing concern about the fast depletion of petroleum-based fuels and the environmental pollution caused by their combustion has been a compelling incentive to many researchers to find ways to use...
研究了EGR率的变化对LPG燃气在稀燃条件下的燃烧、排放以及循环变动率的影响。结果表明,基于高能双火花塞点火的快速燃烧系统可以加快LPG燃气的燃烧速率,有效地改善引入EGR的LPG发动机的快速燃烧过程。在整个有效废气再循环率(REGR)范围内LPG稀燃稀限得到较大幅度提高,同时抑制了发动机因高温而生成的NOx。同时,采用快速燃烧系统的最大REGR为8.11%,大于普通方式的5%;LPG燃烧过程的循...
以石化柴油为参照,在发动机台架上,采用电子低压冲击仪及其附带的两级稀释系统测试了燃用柴油、甲醇柴油和生物柴油排放的不同粒径微粒的数量浓度、体积浓度,分析了发动机转速、负荷以及燃油种类对微粒粒径分布的影响。试验证明:在外特性下,柴油、甲醇柴油排放的微粒数量浓度随转速增大而增加,生物柴油排放的微粒数量浓度随转速没有明显变化规律;在2300r/min,生物柴油和柴油随负荷的减小排放的微粒数量浓度增加;标...
A single cylinder vertical air-cooled diesel engine was modified to use LPG in dual fuel mode to study the performance, emission, and combustion characteristics. The primary fuel, liquefied petroleum ...
专著信息 书名 Nature of OH maser and SiO thermal emission towards carbon star: IRAS 05373-0810(V1187 Ori) 语种 英文 撰写或编译 作者 Szczerba,R.,Chen,P.S.,Szymczak,M.,Omont,A 第一作者单位 出版社 2002, A&A, 381,491 出版地 出版日期 2002...
