Abstract
Comprehensive evaluation of diesel engine performance can provide an effective guidance for the selection of existing diesel engines and the reasoning, design and evaluation of new diesel engines. In order to scientifically, systematically and objectively evaluate diesel engine performance of armored vehicles, thirteen main performance targets are put forward as comprehensive evaluation targets according to its specific operating requirements, based on an all embracive evaluation of the diesel engine performance. The method of weighted comprehensive evaluation is introduced detailedly and the weights of various targets are determined by comprehensive defined weight. The diesel engine performance of different armored vehicles is evaluated comprehensively using this method. This method is an effective, widely applicable and quantificational method. The example cited proves that this method compares intuitively the advantages and disadvantages in the evaluation of the diesel engine performance of different armored vehicles, with the results obtained valid and dependable. It has definite physical meaning and can indicate comprehensive effect of each performance target of different diesel engines. It provides a new method for quantificationally and comprehensively evaluating diesel engine performance.
