【Abstract】 During the low load operation of a turbocharged diesel engine there may emerge a series of inherent characteristics, such as insufficient supercharged pressure, a small excess air factor for combustion and high exhaust gas temperature, etc. To deal with the above deficiencies, a new method has been proposed. It involves the use of exhaust waste heat of a supercharger to produce water steam, which is to be injected into a turbine to enhance the pressure ratio and airflow rate of the supercharger. This will result in an improved matching of the turbocharger and diesel and a better diesel performance.更多还原
