The internal EGR rate is also reduced with increase in the engine load under the same engine rate and scavenging pressure.
在同一转速和扫气压力下，内部EGR率随负荷增大而降低。
Results show that the EGR rate can be effectively regulated by adjusting VNT vane position while still ensuring sufficient fresh intake air mass flow.
结果表明，通过调节VNT开度可以有效控制EGR率，并能保证较充足的新鲜空气量。
Test results show that, the maximum of EGR rate is 15.4%; Compared with original data, the maximum of in-cylinder pressure and average temperature all drop a little.
试验结果表明，在各负荷下EGR率最大值为15.4%：燃烧过程缸内压力的最大值和缸内平均温度的最高值均有所降低；
