Adapting Vehicle Diesel Engine to Power Generation - Conversion Aspects

Abstract

The paper reports the research work performed to convert a diesel engine used in commercial vehicles in a generating set of 65 kVA. The design, manufacture, and testing of the prototype were performed, being emphasized the main conversion problems such as derating from 2800 rpm to 1500 rpm, changing the fuel flow rate of the injection pump, adapting the air flow rate by means of selection of a by-passed turbocharger and intercooler. Special attention was paid to engine speed stability which imposed stringent conditions in order to ensure a constant frequency of the generated AC voltage.
