柴油发动机

With this engine Audi has opened a new chapter in diesel history.

与此发动机的奥迪开辟了新的篇章，柴油的历史。

For Diesel/Gas dual-fuel engine, commixing combustion of gas fuel and diesel in cylinder results in some problems, as economical performance and emissions of engine become worse at light load and knocking combustion at heavy load and so on.

由于柴油和气体燃料的不同物化和燃烧特性，给双燃料发动机带来一些问题，如小负荷时发动机的经济性和排放不好，大负荷工况下易爆震等。

The experiment on the study of QHCCI is carried out on the refitted engine.

本文以改装的柴油／天然气双燃料发动机为实验发动机，对天然气QHCCI燃烧过程的燃烧特性进行了研究。

Sensors, data acquisition cards and virtual instrument software are applied in the electronic control of ethanol injecting for optimized diesel/alcohol dual-fuel engine, through complement factor experiment which combines three fuel supply advance angle with four ethanol supply time, the performance of dual-fuel engine is compared with the original one under same condition.

使用传感器、数据采集卡和虚拟仪器软件改进柴油/乙醇双燃料发动机的乙醇喷射电子控制系统，通过三个供油提前角、四个供醇时刻组合的全因素试验，比较了双燃料发动机与原机相同工况下的性能。

In addition, the HC and CO emissions are much lower than the emissions of HCCI and the indicated thermal efficiency of HCCI/DI is higher than the prototype diesel engine.Furthermore, without spark ignition and hot EGR, the HCCI/DI combustion of in-cylinder directly injected iso-octane is achieved with the induction of thermal and chemical active atmosphere generated by the HCCI combustion of port injected n-heptane.

通过对燃料理化特性、预混合率和缸内直喷时刻这三个影响因素的优化，实现了对HCCI/DI燃烧相位、放热分布和形态的调制，使发动机的负荷拓展到全负荷，在全负荷范围内NOx排放低于40×10-6排放水平，HC和CO排放显著低于HCCI燃烧，同时发动机指示热效率η_i高于原机柴油直喷的水平。

This revamp also saw the introduction of two new engines, a 2.0 version of the existing V6 engine (which retained the carburettors) and a 2.5 litre VM 5 cylinder turbodiesel.

这种改革还看到了两个新的发动机，现行的V6发动机的2.0版本的推出和2.5升5缸涡轮增压柴油船民。

In order to analyze the relationship between radiation heat transfer and thermo-efficiency, the radiant heat flux of the cylinder and thermal balance are measured. The results show that: The reduction of thermal radiant flux in the cylinder is the primary cause of the improvement of thermal efficiency of the engine.

为了研究发动机热效率和辐射传热量变化之间的关系，利用辐射传感器测量了柴油机燃用DMC柴油混合燃料后缸内辐射传热量，进行了热平衡实验，分析结果表明，添加含氧燃料后，发动机缸内辐射传热量的减少是导致其有效热效率的提高的主要原因。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
