“…The general view of the diesel engine is shown in Figure 1. As a result of previous studies, it was found that losses associated with a decrease in the opening time of the intake valves and a slight deterioration in the quality of gas exchange in the cylinders can be partially compensated by an increase in the boost pressure As a result of previous studies, it was found that losses associated with a decrease in the opening time of the intake valves and a slight deterioration in the quality of gas exchange in the cylinders can be partially compensated by an increase in the boost pressure (by selecting the optimal flow paths of the turbochargers) and adjusting the fuel injection advance angle [30,31]. Accordingly, the main goal of these studies was to synchronize the fuel supply with the valve timing of a 21/21 diesel engine.…”

Reducing harmful emissions from exhaust gases and increasing energy efficiency are urgent tasks when designing reciprocating internal combustion engines. In this experimental work, the fuel system of a diesel locomotive engine operating on the Miller cycle is improved. The purpose of the study is to improve the environmental and economic indicators of diesel engines at minimal financial cost. The article provides an overview of the main research on improving fuel supply, mixing and combustion. The features of engine operation are also briefly described. Numerical simulation of the diesel engine operating cycle was performed before the bench tests. The experiments were performed on a full-size diesel engine with a power of 1200 kW. The measuring equipment and experimental technique are described in the article. The technical solutions that made it possible to improve the fuel supply are described. A new design for the high-pressure fuel pump drive is proposed. The optimal fuel injection advance angles are determined. An original design for the fuel pump plunger was developed. The proposed technical solutions made it possible to reduce fuel consumption by up to 3% (from 217.8 to 211.4 g/kW·h) and NOx emissions two-fold (from 19.4 to 8.8 g/kW·h).

The main reason for the emergence of the operational characteristics of tractor diesel engines is the uneven fuel consumption. Fuel equipment is one of the most responsible systems of diesel engines. The purpose of the study was to improve the fuel efficiency of an agricultural tractor diesel engine by using an injector sprayer. Modernization of the needle of the atomizer of the fuel injector is carried out by directing its guiding surface of the helical groove at an angle α, advancing the direction of the axisymmetric fuel pressure. This includes the fuel injector needle, as it is likely to be skewed, stuck, and dependent. The novelty of this design is protected by the patent of the Russian Federation RU 2231673. To assess the fuel efficiency, natural experiments of a diesel engine with serial and modernized injectors were carried out. The introduction of new technical equipment in the fuel equipment has led to the achievement of diesel engine power by 8 … 12% and the rate of retention of fuel consumption by 3 … 4%.
