奔驰s600的amg款
发动机由5。5l弄到了6l(突击数字待查)
力矩750Nm/1500rpm
最大力矩1000Nm/2000-4000rpm
大家有兴趣讨论一下这发动机怎么改的么
都想问问是不是改烧柴油了 哈哈哈

应该不会把烧汽油的改成柴油把。。。。强度可能都不对了。。。
不过增加排量估计是用镗缸的。
然后加上增压……

看着最大扭矩在1500rpm怎么这么奇怪,难道真的是烧柴油啊?

s600已经是双turbo了
镗缸什么的是肯定了
关键是怎么把力矩改成那样的
^_^ 改柴油那是戏言

加大增压压力。
功率太大了没啥用,着重调扭矩吧。
具体的可以查查DC媒体网站上的详细资料。
这种跨国公司的资料非常全。
我去找找。

bt的dc喜欢作这样的曲线
他们的做法是用一套电控的进气控制单元提升低转速的扭矩
至于功率,则被牺牲掉了不少

Twelve-cylinder biturbo engine with know-how from motorsport
This exclusive performance is made possible by the 5980-cc V12 engine developed by Mercedes-AMG. The engine’s credentials are outstanding: maximum output of 450 kW/612 hp is maintained from 4750 to 5100 rpm, while the maximum torque of 1000 Nm can be called on from 2000 to 4000 rpm. Even as low as 1000 rpm, the AMG V12 biturbo engine already delivers 570 Nm of torque to the crankshaft, while 750 Nm is on tap at 1500 rpm.
When designing and building the V12 engine the AMG designers drew on the vast know-how amassed over many years of motorsport involvement. The AMG V12 engine has a precision-balanced crankshaft made out of high-strength materials, forged pistons made out of special material which is extremely resistant to temperature and pressure, a more effective oil-spray cooling system with a separate individual nozzle for each piston plus larger piston pins. The main and big-end bearings are also made out of improved materials to compensate for peak temperatures and pressures more effectively. The charge cycle in the cylinder heads benefits from optimised combustion chambers and longer opening times of the intake valves. A modified oil pump ensures that all lubrication points are supplied with oil - even in highly demanding conditions. An engine oil cooler is integrated into the AMG front apron, with an additional engine coolant radiator located in the wheel arch.
Highly efficient charge-air cooler
The charge-air cooler has also been redesigned with a low-temperature radiator in the front of the vehicle that is around 70 percent larger. The system works on the principle of the air/water heat exchanger for particularly effective cooling of the intake air (which has been compressed by the turbochargers) before it enters the combustion chambers. The increased surface area of the low-temperature radiator provides a 25 percent reduction in intake temperature and guarantees high power and torque output under all operating conditions and regardless of the outside temperature, even when the engine is operating at full load. The housings of the compressor and turbine in both turbochargers as well as the turbine and compressor wheels have been enlarged to cope with the maximum charge pressure of 1.5 bar.
The electronically controlled fuel supply with newly developed components operates with a variable system pressure between 3.6 and 5.0 bar. Depending on the power requirements and outside temperature, the fuel pressure is variably controlled almost instantly. The engine management system translates the command from the accelerator within milliseconds, delivering an extremely fast response from the engine in all load situations.
