制造功率为6000马力的机车发动机是机车制造业迫切的任务。 16缸370发动机在1000转/分及高的平均有效压力P_6=18.4公斤/厘米~2时,功率达N_6=4000马力。我们分析一下可能提高同类发动机功率的措施。为此,列出确定发动机有效功率的表达式: N_6=P_6·V_h·n·z/225i 到目前为止,平均有效压力P_6的数值已达到18.4公斤/厘米~2。过分提高转速n的数值是不适宜的,因为,该型发动机的活塞平均速度也相应提高
It is an urgent task for locomotive manufacturing to make a locomotive engine with a power of 6000 horsepower. 16 cylinder 370 engine at 1000 rev / min and high average effective pressure P_6 = 18.4 kg / cm ~ 2, the power of N_6 = 4000 horsepower. We analyze the possible measures to increase the power of similar engines. For this purpose, an expression for determining the effective power of the engine is listed: N_6 = P_6 · V_h · n · z / 225i The mean effective pressure P_6 has so far reached 18.4 kg / cm ~ 2. Excessive increase in the value of speed n is not appropriate, because the average piston speed of the engine is also increased accordingly
