2、救急!!!汽车方面英文文章(约10000个单词)要有翻译的
Diesel vehicles
Diesel vehicles may be making a comeback. Diesel engines are more powerful and fuel-efficient than similar-sized gasoline engines (about 30-35% more fuel efficient). Plus, today's diesel vehicles are much improved over diesels of the past.
柴油车柴油车可能正在东山再起. 柴油引擎更强大,更省油,比同样大小的汽油发动机(约30-35%的燃油效率) . 再加上,今天的柴油车,大大改善了柴油机的过去.
Better Performance
Improved fuel injection and electronic engine control technologies have
Increased power
Improved acceleration
Increased efficiency
New engine designs, along with noise- and vibration-damping technologies, have made them quieter and smoother. Cold-weather starting has been improved also.
表现较好的改善燃料喷射和发动机电子控制技术的进步已增加力量加快改善效率,增加新的引擎设计, 随着噪声及减振技术,取得了他们的宁静和畅顺. 寒冷天气开始有所改善也.
Cleaner
Today's diesels must meet the same emissions standards as gasoline vehicles, and advances in engine technologies, ultra-low sulfur diesel fuel, and improved exhaust treatment have made this possible.
Although emissions of particulates and smog-forming nitrogen oxides (NOx) are still relatively high, new "clean" diesel fuels, such as ultra-low sulfur diesel and biodiesel, and advances in emission control technologies will rece these pollutants also.
今天清洁的柴油,必须符合相同的排放标准,汽油车,先进的引擎技术, 超低硫柴油,并改进尾气处理有这个可能. 虽然排放的悬浮粒子和烟雾形成的氮氧化物( NOX )仍比较高,新的"干净"的柴油燃料相比, 如超低含硫量柴油,生物柴油和垫款在排放控制技术,可减少这些污染物也.
Hybrid-electric vehicles;
Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.
Some of the advanced technologies typically used by hybrids include混合电动车; 混合动力电动汽车(的HEV )结合的好处,汽油发动机和电动马达,可以通过配置来获取不同的目标,这种 作为提高燃油经济性,提高动力,或额外的辅助电源的电子设备和电动工具. 一些先进的技术,通常用杂交种包括:
Regenerative Braking. The electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted ring coasting and braking into electricity, which is stored in a battery until needed by the electric motor. 再生制动. 电动机电阻适用于传动造成车轮放慢了. 作为回报,能量从车轮转动马达,它的功能是一台发电机, 能源转换通常浪费在滑行和刹车成电力, 这是储存在电池直到所需的电机.
Electric Motor Drive/Assist. The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. In some vehicles, the motor alone provides power for low-speed driving conditions where internal combustion engines are least efficient.
电机驱动/协助. 电动机提供额外的权力,以协助发动机在加速,超越,或爬山. 这使得规模较小,更加高效的引擎可以使用. 在一些车辆,电动机单独提供电源低速驾驶的情况下,内燃机是最有效的.
Automatic Start/Shutoff. Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.
自动启动/关机. 自动拒之门外引擎当汽车来停止并重新启动它时,油门被按下. 这样可避免浪费能源,从空转.
Flexible fuel vehicles (FFVs)
Flexible fuel vehicles (FFVs) are designed to run on gasoline or a blend of up to 85% ethanol (E85). Except for a few engine and fuel system modifications, they are identical to gasoline-only models.
FFVs have been proced since the 1980s, and dozens of models are currently available. Since FFVs look just like gasoline-only models, you may have an FFV and not even know it. To determine if your vehicle is an FFV, check the inside of your car's fuel filler door for an identification sticker or consult your owner’s manual.
灵活燃料汽车(FFVs)灵活燃料汽车(FFVs) ,设计运行于汽油或混合最多 85%乙醇( e85 ) . 除了少数的发动机和燃油系统的改装,它们是相同的汽油只有模型. 灵活燃料汽车已累计生产80年代以来,几十种型号,目前可用. 自灵活燃料汽车很像汽油唯一模式,你可以有一个新鲜水果和蔬菜,甚至不知道它. 确定如果你的汽车是一个新鲜水果和蔬菜, 检查内你的车子的加油口门上一贴,鉴定或请教你的车主手册.
FFVs experience no loss in performance when operating on E85. However, since a gallon of ethanol contains less energy than a gallon of gasoline, FFVs typically get about 20-30% fewer miles per gallon when fueled with E85.
灵活燃料汽车的经验,没有任何财物损失,在性能上经营e85 . 然而,由于一加仑乙醇含有更少的能源比一加仑汽油, 外国船队通常有约20-30%少英里每加仑,当燃用e85 .
Electric vehicles (EVs)
Electric vehicles (EVs) are propelled by an electric motor (or motors) powered by rechargeable battery packs. Electric motors have several advantages over internal combustion engines (ICEs): 电动车(电动车)电动车(电动车) ,发动机由电动机(或马达)提供动力的电池包. 电动马达拥有几项优势内燃机(考) :
Energy efficient. Electric motors convert 75% of the chemical energy from the batteries to power the wheels—internal combustion engines (ICEs) only convert 20% of the energy stored in gasoline.
Environmentally friendly. EVs emit no tailpipe pollutants, although the power plant procing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind-powered plants causes no air pollutants. 能源效率. 电动马达,将75%的化学能量从电池为电源的车轮-内燃机(考) ,只有转换 20%的能源储存汽油. 环保. 电动车不会排放废气污染物,虽然电厂生产的电力,排出的可能. 电力来自核,水能,太阳能,风能发电厂没有造成空气中的污染物.
Rece energy dependence. Electricity is a domestic energy source.
Performance benefits. Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than ICEs.
The Down Side: Batteries
减少对能源的依赖. 电力是国内的能源来源. 性能优点. 电动马达提供安静,平稳操作和强大的加速度,需要的维修较少,比考. 弊:电池
EVs face significant battery-related challenges:
Driving range. Most EVs can only go 150 miles (or less) before recharging—gasoline vehicles can go over 300 miles before refueling.
Recharge time. Fully recharging the battery pack can take 4 to 8 hours.
Battery cost: The large battery packs are expensive and usually must be replaced one or more times.
Bulk & weight: Battery packs are heavy and take up considerable vehicle space.
Researchers are working on improved battery technologies to increase driving range and decrease recharging time, replacement frequency, weight, and cost. These factors will ultimately determine the future of EVs. 电动车面临着电池相关的挑战:练习场. 大部分电动车只能走150英里(或更少) ,然后充电汽油车辆可走300英里,然后加油. 充电时间. 完全充电的电池包可以采取4至8小时. 电池成本:大型电池盒十分昂贵,通常必须更换1次或更多次. 体积及重量:电池包重,并采取了相当多的车辆空间. 研究人员正在改进电池技术,以增加练习场和减少充电时间,更换频率,重量和成本. 这些因素最终决定自己前途的电动车.
