Масштабная модель Mercedes 300 SLR 1955 Engine With Showcase
The basic design of this engine, apart from displacement, is virtually akin to what we see in the engine of the Grand Prix car W196. By comparison, the displacement of the 300 SLR engine is 486 см.куб larger than that of its counterpart, while its stroke/bore is increased to 78 x 78 мм. Moreover, the top speed is attained at 7,500 об/мин in this engine, as against 8,500 об/мин in the W196 engine.
The 300 SLR was so designed that even when the engine was running on low speed, a fast revving-up capacity was available. This feature mattered a lot in sports car races, where good acceleration provided a very positive advantage. In the building of the 300 SLR engine, a cylinder block made of AluMinium alloy was adopted for the first time. Likewise, its cylinder liner was made of chromed AluMinium instead of steel. Both represented cutting-edge engineering of their time.
