Abstract
The purpose of this paper is to investigate starting characteristics of multicylinder diesel engines which are operated by the compressed air. A non-supercharged three cylinder diesel engine was chosen as the calculating model engine, so that the engine speed was raised in various starting conditions, then some characteristics of the engine were calculated by a Hybrid computer.
In the simulation program, all dynamics of the engine including the governor, gas pressure and gas temperature in the cylinders were computed with the analog components and data of the friction losses and rates of heat release were calculated with the digital system. The approximate equations which were obtained from engine tests were applied.
The calculated results agreed approximately with the test results of the engine.
