The turbo was also available with the four wheel drive Quadra transmission, and was capable of 227 km/h. The Renault 21 hatchback and sedan petrol-fueled models ceased production in early 1994 on the launch of the all-new Laguna hatchback, but the diesels and the Nevada remained on the market until their replacement Laguna variants were launched (late 1994 for the diesels and late 1995 for the Nevada).

在涡轮发动机也可与四轮驱动外接传输，并为227公里/每小时雷诺的21掀背车和轿车汽油为燃料的车型在1994年初停止生产的全新拉古娜掀背车的推出，但内华达州和柴油市场上，直到他们更换丽变种展开（已晚柴油和1994年1995年末为内华达州）。

When diesel/CNG dual-fuel turbocharge intercooling engine D6114 runs in dual-fuel mode, only diesel fuel is supplied when starting and idling, and when engine speed is beyond the preset value,electronic control system send out command to limit diesel fuel injection amount,and natural gas begin to enter into cylinder through mixer to take part in burning, at this time small a mount of diesel fuel shall play mainly a role of ignition,and engine load is changed by altering natural gas supply amount.

D6114柴油/CNG双燃料增压中冷发动机当以双燃料方式工作时，发动机起动和怠速只燃用柴油；当转速超过某设定值，电控系统发出指令限制柴油的喷油量，天然气经混合器进入气缸参与燃烧，此时少量柴油供给主要起引燃作用，发动机负荷变化则通过改变天然气供给量的大小来实现。

Issues addressing the green chemistry design of engine fuel systems include lead free and anti wearing of gasoline,low sulfurization and lubricity of diesels,eco fuels and eco tribology,gasoline engine deposits and detergents...

发动机燃料系统绿色化学设计的范畴包括：汽油无铅化与汽油抗磨性，柴油低硫化与柴油润滑性，生态燃料与生态摩擦学，汽油机沉积物与汽油清净剂，柴油机颗粒与消烟助燃剂。

Nearly all diesel-powered equipment can use blends of up to 20 per cent biodiesel, and many engines can use higher-level blends or even pure biodiesel with little or no modification.

几乎所有的柴油动力设备可以使用最高混合20%生物柴油的燃料，而且许多发动机不需要改造就可以使用更高混合比的燃料，甚至使用纯生物柴油。

Bio-diesel One, a South African company, has installed a test processor and has shown that a blend of five per cent biodiesel and 95 per cent petroleum diesel improves engine performance, offers enhanced lubricity and some reduction in emissions.

南非的一家名为Bio-diesel One的公司已经安装了一台实验性质的处理机，而且证明了把5%的生物柴油和95%的石油柴油混合可以改善发动机的性能，提供增强的润滑并减少了一些排放。

Cummins manufactures and markets a complete line of diesel engines for on-highway and off-highway use and natural gas engines for automotive and stationary applications.

博世汽车柴油系统股份有限公司全力满足中国乘用车和轻、重型商务车以及非道路用发动机对现代柴油技术日益提高的需求。

The effects of biodiesel blending fuels with different biodiesel fractions on the exhaust emission characteristics of the diesel engine were investigated on a heavyduty automotive electronically controlled highpressure commonrail diesel engine. Five diesel/biodiesel blends were tested according to ESC steadystate 13mode test cycle without modifications of engine construction and parameter adjustment.

针对一台大排量电控高压共轨柴油机，在发动机的结构和参数不作变动和调整的条件下，使用5种生物柴油混合燃料进行ESC稳态排放测试，研究了不同生物柴油含量的混合燃料对柴油机排放特性的影响。

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