The launch of the new Fiat Bravo is also an opportunity to present the new family of turbocharged T-JET petrol engines (120 and 150 bhp 1.4 Turbo), which combine fuel economy, low emissions and exceptional performance, and now join the popular range of Multijet common rail turbodiesels (1.9 litres delivering 120 and 150 bhp) and the 90 bhp 1.4 16v petrol engine.

新菲亚特布拉沃推出也是一个机会，以目前的涡轮增压电报公司的新系列射流汽油发动机（120和150马力1.4升），其中集成的燃油经济性，低排放和非凡的性能，现在加入流行范围多点喷射共轨turbodiesels（1.9公升提供120至150马力）和90马力1.4升的16V汽油发动机。

At the launch the model will be offered with a choice between a petrol engine (1.4 8v, 77 bhp) and a turbodiesel (1.3 Multijet 16v, 90 bhp with a variable geometry turbo), both combined with five-speed mechanical transmissions; the 120 bhp 1.4 16v Turbo from the new T-Jet family will be available at a later date.

在该模型将与汽油发动机之间（1.4 8V的选择，提供了发射77马力）和一个涡轮增压柴油发动机（1.3多点喷射16气门，90可变几何涡轮增压马力），同时结合五速机械传动； 120马力涡轮增压1.4升16v从全新的T -喷气系列将在日后公布。

To solve the problems that cyclic variation is high in low power output and NOx emission is high in high power output in compression ignition engine with compressed natural gas direct injection,a swirl chamber combustion system with glow plug ignition was developed.

针对缸内直喷压燃式天然气发动机低负荷循环波动大及高负荷NOx排放偏高的问题，设计开发了涡流室式热面点火燃烧系统，研究了涡流室通道尺寸对缸内天然气空气混合气形成、着火燃烧及发动机运转特性的影响。

The main source of inefficiency in Newcomen's engines was the repeated alternate heating and cooling of the main cylinder, and it was James Watt ( 1736 -1819) who devised an engine which avoided this wasteful procedure.

纽科门发动机效率低下的一个主要原因在于它需要不断地对主圆筒交替进行加热和制冷，詹姆士-瓦特(1736-1819)设计出的一种发动机避免了这一浪费步骤。

The motor consists of a cluster of four YF-2 engines which use storable liquids, Unsymmetrical Dimethyl Hydrazine fuel and AK-27 oxidiser (nitric acid with 27% nitrogen tetroxide), and provide a total thrust of 96 tonnes.

发动机由四台集群YF-2发动机组成，使用耐储存液体不对称二甲肼燃料和AK-27液氧（硝酸和27%氮四氧化物），而且提供96吨的一个总推力。

Research on decreasing consumption of energy, levels of exhaust, vibration and noisiness can provide a basis for improving engine performance; however, more exact, convenient and efficient methods must be used to measure an engine's working properties.

研究发动机能耗、排放、振动和噪声等特性，可以为改进发动机性能等提供依据，但须采用准确、方便和有效的测试方法。

NOSE CONE, A device on the front of the engine that guides airflow to the primary airflow path of the engine.
