比较同情这些人,上当后才知道后悔。希望像您这样有正义的人再多一些,多宣传一些,让广大的模友都看看某国产车的真实面目。华为怎么样?我没有宣传他们有多好,起码比某国产的要好。

呵呵,这下就明白你的用意了,大家也都看的明白啦。
These big-bore kits have been race ported - intake, exhaust, and transfer ports have been enlarged/reshaped for more fuel/air flow and hence more power. If displacement is what you crave, look no further. This custom DDM big-bore combo kit will allow you to convert your current engine into a race ported 30.5cc performance monster. Feel the power that only a larger engine can provide. Kit includes race ported 36mm cylinder, modified 36mm piston, piston ring, piston pin and two pin washers, circlips, two cylinder bolts, insulator gasket, CMR7H spark plug, choice of 30mm stroke crankshaft, and .040" copper cylinder gasket to provide increased clearance for the longer crankshaft. Increases your engine displacement to 30.5cc (36mm bore, 30mm stroke). Increases engine power SUBSTANTIALLY - estimated engine power output is 4.25+ HP. This high-performance product requires 91 octane (using the R+M/2 octane rating method) or higher fuel, and comes without warranty. Fits Zenoah G23LH / G230RC / G260RC engines. Also fits Chung Yang CY23RC / CY26RC / CY27RC / CY29RC / GP290 engines.
For Scooters: Fits any scooter using one of the above engines. Fits Sport, Liquimatic, Bigfoot, X-ped, Super X-ped, Super Bigfoot, Go-Quad, Super Go-Quad, Go-Quad 30, GSR26R, GSR29R, and Homebuilders Kit.
For R/C: Fits a wide variety of 1:5 and 1:6 R/C cars, planes, boats, and helicopters. Same mounting dimensions as Zenoah G230RC / G260RC. For cars - fits FG: Marder, Leopard, Monster Beetle, Monster Truck, Stadium Truck, and Pajero. Also fits Smartech Traveler, Firehammer, XTM, Carson Attack, HPI Baja 5b, and other large scale RC cars.
这个是进口30.5CC的说明,30.5CC并不是如你所说的什么扩缸,活塞这些是可以通用29CC的,30.5CC的汽缸在于修改了扫气道等位置,同时需配合使用加2或者加1曲轴,我们曲轴的标准为28MM,其实是不是30.5CC发动机,和29CC发动机一起拉着就能感觉的到了,30.5CC属于扭矩型的发动机,在高速上其实是没有29CC跑的快的,因为它加长了2MM曲轴,在缸头内的运动速度提高,而增加了瞬间的输出力,在急速上的话就要比常规曲轴稍慢,所以DDM还有一种加1的曲轴,就是为不比要损失太多高速,还有更高级点的TS的发动机,也需要配合加1~加2曲轴来完成,同时还可以更换压缩比帽子,一般用13压缩比的帽子,过大的话需要更高标号的汽油,120号或者更高,这些我们买不到的。
在这里DDM的套件也没有说明详细的数据,就连同4.25P马力的数据也是估计的,因为30.5CC发动机是需要手改完成的,没有人能保证每一台手改机器的输出是100%相同,还有,30.5CC的所有组件包括曲轴想加,也不过1KG左右几乎是不到的,你如果真的懂发动机,我相信你会比制作这中排量发动机的人更懂得数据的,不过还是要再次提醒下,30.5CC发动机不是扩肛。。。 这些不属于基础知识了,你应该能够学习到。 |
