查询词典 Diesel

A new model for the autoignition of pilot diesel in the mixture of methane with air was proposed and validated with experiments.

着火模型的基本框架仍然采用Shell模型，但考虑到CH4 对柴油着火过程的影响，修正了Shell模型。

This paper presents a new model describing the autoignition of pilot diesel in the mixture of methane with air for dual fuel engines.

预测发动机的燃烧启动和敲缸都需要研究发动机的着火过程以及开发发动机的着火模型。

DME,as a kind of alternative fuel of diesel engine,has been researched by the worldwide engine researchers for many years and a profound understanding of the spray,autoignition,and combustion process of DME has been acquired.

多年来各国对DME作为柴油的代用燃料作了大量的研究，对DME的喷雾过程、自燃着火过程和燃烧过程等方面有了较为深入的了解。

The skeleton of the new autoignition model is based on Shell model, which considers the effect of methane on autoignition of diesel.

由于着火过程持续时间较短，仅占湍流燃烧过程的一小部分，因此，在能够充分描述着火过程主要特征的情况下，着火模型应尽量简单，所以，虽然有文献提出了着火过程的详细化学动力学模型，实际上一般倾向用简化的化学动力学模型 [1]，这是Shell着火模型至今仍然得到广泛应用的原因。

DMEbecomes a potential alternative fuel,for its excellent autoignition performance and capacity to meet ULEV emissions standards for diesel engines without any exhaust gas after-treatment.

由于DME有良好的压燃着火性能以及不需特别的措施就能达到超低排放标准，因而成为柴油发动机一种很有潜力的替代燃料。

The results show that the liftoff height of the CH4/Air jet flame decreases with the increase of the coflow temperature, and the change of the liftoff height versus the coflow temperature presents the twostages behavior, and the stabilization of lifted flame is dominated by the autoignition of premixed homogeneous mixture in lower coflow temperature range. The phenomena of rapid multipoint autoignition were observed in the experiment of diesel fuel spray issuing into the CATA, and a special lifted flame appeared with a triple flame.

结果表明：甲烷气体燃料火焰起升高度随协流温度的升高而降低，呈现出两阶段变化特点，低温段发生了明显的自燃现象，其火焰稳定由均质混合气自燃所主导；柴油液雾燃烧试验观察到了快速的多点自燃现象，形成了独特的起升火焰，有三重火焰的特征。

We strapped it down on four points, and Dave had me toss my jackets, helmet, and other gear into the back of his quad-cab diesel monster truck.

我们绑下来的4分，和Dave了我抛我的夹克，头盔和其他装备的回他的四怪物卡车驾驶室柴油。

The effect of additive in CC grade diesel engine oil on the formation of lacquer on the surface of lacquer plate was studied by mirror reflectance infrared spectroscopy;the formation of lacquer on the lacquer plate has the correlation with formation of lacquer on banquette of Cat.

利用镜反射红外光谱法研究了CC级柴油机油中添加剂对成漆板板面漆膜组成的影响；考察了成漆板漆膜组成与Cat。

This paper discusses the principles and methods for diagnosing faults in diesel engines based on Bayes networks .

讨论了基于 Bayes网络的数据融合技术应用于柴油机故障诊断的原理和方法。

Where petrol and diesel-powered vehicles now account for almost all those on the road, by 2050 they would be in a minority, with some combination of battery, hydrogen and advanced biofuel used in the rest.

今天，马路上跑的几乎全是以汽油和柴油为动力燃料的汽车；而到2050年，它们将只占少数，其余车辆都将使用电池、氢和高级生物燃料所构成的某种混合动力。

Aquatic or marsh-growing fern allies; known to have existed since the Cenozoic; sometimes included in Lycopodiales.

生活于水中或湿地的蕨类；从新生代生存至今；有时归于石松目之中。

The engine was uprated from a 90hp Franklin to a 125hp Lycoming.

改良过的引擎是从90hp到125hp莱康明富兰克林。
