在小型柴油机上使用可调节的废气涡轮增压器可以使最大扭矩移到较低转速范围内并提高其值。大的过量空气系数能实现上述结果且其烟度指数不超过 ECE 的极限值。较高转速范围内的燃油消耗率上升5%。本文报道 KKK 公司对两台带旁通放气阀的 KKK 增压器的小型柴油机进行试验的结果。文中所述虽为车用柴油机高负荷时的旁通放气系统,但它完全可以用在拖轮和拖网渔轮等船用柴油机上,它是一个低转速高扭矩的有效措施。
Using an adjustable exhaust gas turbocharger on a small diesel engine allows the maximum torque to be shifted to a lower speed range and increased. A large excess air factor can achieve the above results and its smoke index does not exceed the limit of ECE. Fuel consumption in the higher speed range increased by 5%. This article reports the results of a KKK trial of a small diesel engine with two KKK turbochargers with bypass bleed valves. Although the vehicle described in this article is a bypass deflation system for high load diesel engines, it can be used on marine diesel engines such as tugboats and trawlers. It is an effective measure for low speed and high torque.
