通过专门试验台可以决定部分进气时径流涡轮增压器的流量及效率,发现与全进气时性能有明显差别通流试验结果已用于数学模型,以预示涡轮增压汽车柴油机的性能。得到计算与测量之间比较符合的结果,从而证明了方法的正确性。
Through the special test bench, the flow rate and efficiency of the partial turbocharger can be determined when the partial intake is in progress. It is found that the performance of the turbo turbocharger is obviously different from that of the full intake. The result of the flow test has been used in the mathematical model to predict the performance of the turbocharged diesel engine. Get the more appropriate results between calculation and measurement, which proves the correctness of the method.
