the turbocharged direct injection or TDI 涡轮增压直喷或TDI
is a design of turbo diesel engines that 是涡轮增压柴油发动机的设计，
feature turbo charging in cylinder 特色涡轮增压缸
direct fuel injection 直接燃油喷射
this technology is proudly developed and 这项技术自豪地开发和
produced by the Volkswagen Group the TDI 由大众汽车集团生产的TDI
engine used direct injection where a 发动机用直接喷射在哪里
fuel injector sprays atomized fuel 燃油喷射器喷雾雾化燃料
directly into the main combustion 直接进入主燃烧
chamber of each cylinder rather than the 每个气缸的腔室而不是气缸
pre combustion chamber prevalent and 预燃室普遍存在
older diesels which used in direct 直接使用的旧柴油机
injection the engine also uses forced 注射发动机也使用强制
induction by way of a turbocharger to 通过涡轮增压器进行感应
increase the amount of air which is able 增加 能够的空气量
to enter the engine cylinders and most 进入发动机气缸，最
TDI engines also feature an intercooler TDI发动机还具有中冷器
to lower the temperature and therefore 降低温度因此
increase the density of the charged or 增加带电或密度
compressed air from the turbo thereby 因此来自涡轮的压缩空气
increasing the amount of fuel that can 增加可以的燃料量
be injected and combusted these in 注入并燃烧这些
combination allow for greater engine 组合允许更大的引擎
efficiency and therefore greater power 效率，因此更大的力量
outputs from a more complete combustion 燃烧更完全的输出
process compared to indirect injection 与间接注射相比的过程
while also decreasing emissions and 同时，还减少排放和
providing more torque than its non turbo 提供比非涡轮增压更大的扭矩
and non direct injection control engine 和非直接喷射控制发动机
counterpart 对方
similar technology has been used by 类似的技术已被用于
other automotive companies but TDI 其他汽车公司，但TDI
specifically refers to these folks 具体是指这些人
bagging troop engines the reduced 装袋部队发动机减少了
material volume of the injection 注射材料量
injection diesel engine reduces heat 喷射柴油发动机减少热量
losses and thereby increases engine 损失，从而增加发动机
efficiency at the expense of slightly 效率略有牺牲
increased combustion noise a direct 直接增加燃烧噪音
injection engine is also easier to start 注射发动机也更容易启动
when cold due to more efficient placing 由于更有效的放置冷
and usage of glow plugs TDI engines are 和使用电热塞TDI引擎
