Features of cold start of 6ЧН 13/11 engine and after start warming-up of engine and transmission unit of T-150K tractor

Abstract

The article analyzes the features of diesel engine cold start in conditions of low ambient temperature. A method for estimation of fuel combustion incompleteness in period of after start warming-up has been developed. Particular method estimating the efficiency of burned fuel heat utilization is proposed. Reliability of the proposed methods has been confirmed experimentally. The article outlines the ways of improving the efficiency and reliability of machines’ performance by means of reducing the warming-up time of engine and transmission unit in after start period.
