| The engine has increased size and height significantly overhangs the top of the body, resulting in the dimensions of the fairing behind the driver's seat significantly increased, while the external shape of the fairing to be not so great as in cases where such a radome is in addition to the hood over the driver's head. On some vehicles, engines, having a greater height, sometimes obliquely set relative to the longitudinal vertical plane. Greater weight loss increases the rolling resistance and makes it difficult to overclock the car. Weight reduction achieved by the creation of racing cars parts most efficient shapes and sizes, as well as using the most high-quality materials that allow high voltages. In all cases where this is possible in terms of durability, used light alloys. High efficiency Power transmission is achieved by careful handling and assembly of all the details and the application of high-quality lubricants. For racing cars in the average efficiency of power transmission rim = 0,9, but in some cars) reaches a value of 0,92-0,95. To obtain a high speed car must have gear ratio, chosen in accordance with the increase in capacity, and to carry out rapid acceleration - have a sufficient number of stages in the gearbox (4-5 steps) and a definite correlation between their ratios. |
