Formation and Study of Static and Dynamic Characteristics of Electronically Controlled Diesel Engine

Abstract

Manufacturing companies of electronic control systems of diesel engines protect access to a program operation algorithm of the regulator that makes impossible adjustments and settings of its work, for example, at re-equipment or operational development of a new diesel engine. Therefore, it is important to acknowledge the solution of the scientific and technical problem of an effective and reliable system creation of electronic control of diesel fuel supply with an open program algorithm of its work. During the current research, settlement and experimental studies of a diesel engine supplied with a system of electronic control of a crankshaft rotation frequency developed by the authors show rather high adequacy in results. The dynamic mathematical model of the single-cylinder diesel engine supplied with the electronic regulator of rotation frequency has been developed and verified.

Determining the characteristics for the rational adjusting of an fuel-air mixture composition in a two-stroke engine with internal carburation

“…To obtain the best efficiency of using hybrid drives in cars, it is necessary to rationally adjust by electronic means both the engine itself [9,10] and its mutual operation with a power electric battery [11]. At the same time, the level of emission of not only harmful substances from exhaust gases into the atmosphere [12] and soil [13] but also from the products of complete combustion (CO 2 ) [14] is the main criterion for optimal adjustment.…”

Analysing the Response of a Dual-Flow Transmission (Hmcvt) for Wheeled Tractors According to Efficiency and Productivity Criteria

“…Most researchers separate these requirements and solve them separately. The aim is to improve the performance of the powertrain, which consists of an internal combustion engine [1,2] and transmission, to meet the driver's speed requirements. Such a development usually does not take into account indicators of economy and efficiency, and sometimes does not comply with agro-ecological requirements for the treatment of agricultural land.…”
