Basic Design of Turbocharged Two-Cycle Diesel Engine

Abstract

In the previous paper, the present authors developed a method of estimating the performance of turbocharged Diesel engines in equilibrium operating conditions, in which the simultaneous equations existing among operating variables were graphically solved. By applying the same method, the characteristics dimensions of turbocharged two-cycle Diesel engine are calculated on the basis of given values of six operating variables at design point, i.e., excess air ratio, delivery ratio, total efficiency of turbocharger, scavenging air temperature, piston speed and brake mean effective pressure. Further, effects of these values on the performance are found out.
