新西兰问个问题。Mazda新的SKYACTIV-D 2.2柴油发动机比现代
在新西兰
Mazda：
KYACTIV-D is a family of turbocharged diesel engines, designed to comply with global emissions regulations.
To eliminate the need of NOx and particulate treatment in contemporary diesel engines, the cylinder compression ratio is reduced to 14.0:1. Cold engine start is achieved via multi-hole piezo injectors with 3 programmable injection patterns, adoption of ceramic glow plugs. Engine misfiring is prevented via variable valve lift at exhaust, which opens exhaust valves during the intake stroke, which increases engine air temperature. SKYACTIV-D also uses a two-stage turbocharger in which one small and one large turbo are selectively operated according to driving conditions.
The SKYACTIV-D 2.2 (SH-VPTS) engine is the first SKYACTIV-D engine used in production vehicles. It was first used in Mazda CX-5. In the Mazda6, it produces 129 kW (173 hp) and 420 N·m (310 lb·ft).
Hyundai：
The 2.2L R-Engine is a 4-cylinder all-aluminum (block and cylinder head) unit, with chain driven dual overhead camshafts operating 4-valves per cylinder. Fuel is supplied to the unit using Bosch 3rd-generation common rail direct injection (CRDi) through piezo-electronic injectors operating at 1800 bar, with air being fed through an electronically managed variable geometry turbocharger and an advanced engine control unit (air system-based charge control).
Bore and Stroke are 85.4 mm (3.4 in) x 96.0 mm (3.8 in) for a total displacement of 2199 cc.
It generates 147 kW (200 PS; 197 hp) of power and 436 N·m (322 lb·ft) of torque

目前现代的柴油2.2是公认的先进柴油发动机。但是Mazda的这个2.2柴油机好像也很有特点，比如很低的压缩比

没人知道？

没人讨论柴油啊

一個好像單turbo
一個 雙 turbo
棒子做的車看看就好啦

相对来说，我更偏向于现代的 CRDI 技术。对马自达的 SKYACTIV-D 2.2 技术存在疑问更多。。。

那么晚了，该睡了

现代的技术应该都是引进的吧？现代之前引进了很多三菱的技术，柴油技术也是从三菱引进的么？

捉住。陪我吃夜宵。。。。。。走起

更低的压缩比 加 piezo 喷油嘴加 可变式涡轮增压 加pdf. 是共轨高压柴油机的趋势 整套系统各个厂家都是大同小异

宋哥对柴油机也有研究啊

楼主可以查查最近几年的世界发动机评比的奖项，柴油的都是欧洲车比较好，朋友去欧洲回来了说欧洲一半都是柴油车，新西兰也是最近5年开始流行柴油了，主要是汽油涨价了，还有就是政府和车行都比较推荐柴油的版本。有的时候是省油但不一定省钱。
欧洲淘汰的技术到了韩国人那就是最新的技术了么

CRDi 是经受了足够久的本地市场考验的。MAZDA的话，虽然上代MZR 2.2D在欧洲推出多年了.但现在是首次在澳新推出柴油车款，相配套的维护体系，零件供应都不知怎样。但是柴油的cx-5和Mazda 6都很收欢迎就对了。

问题是那些得奖的柴油发动机，不一定适合纽西兰国情

柴油版应该卖的比汽油好很多
