The toxicity indicators of exhaust gases of a diesel engine largely depend on the quality of the fuel supply process. The possibility of a significant improvement in the toxicity of the exhaust gases of a diesel engine by optimizing the phase of the start of fuel supply - the fuel injection advance angle is shown. To assess the influence of the fuel injection advance angle on the dynamic performance of the engine and the toxicity of exhaust gases, a mathematical model of the engine has been developed. The model contains differential equations for the main elements of the combined engine - its piston part, turbocharger, in take and exhaust pipelines. These equations include polynomial dependences of the main engine parameters on its operating parameters. The object of research was diesel type D-245 (4 ChN 11/12.5) produced by the Minsk Motor Plant. Calculations of the acceleration of the engine with a variable fuel injection advance angle have been carried out. The influence of the law of regulation of the advance angle of fuel injection on the duration of the transient process and emissions of normalized toxic components is determined.

“…13 Today, CI engines are the prime movers of choice for railroad locomotives, heavy earth-moving equipment, heavy-duty and light-duty vehicles, buses, trucks, cars, and auxiliary power generators. 14,15 They are used extensively in mining and dock operations and as powerplants in remote areas, where other electricity sources are not available. 16,17 However, CI engines give rise to pollution because they emit PM, NO x , and several other gaseous pollutants of concern.…”

Particulates from compression ignition (CI) engines have received serious attention in the last two decades. CI engines emit higher particulate matter (PM) and nitrogen oxides (NOx) than spark ignition (SI) engines. Both these species are harmful to human health and the environment. Compared to NOx emissions, PM constitutes many more chemical species in solid and liquid phases. This review paper focuses on soot morphology and chemical characterization of PM emissions from CI engines. Effects of different fuels, lubricating oil, and engine operating conditions on particulate characteristics are analyzed exhaustively. The first part of this paper focuses on the effects of particulates on living organisms, the consequences of exposure to diesel particulates, and the composition of diesel particulates. In recent decades, micro and nano-scale characteristics of PM have been exhaustively investigated to understand its structure, formation, and chemical functionalities. Typically, particulates comprise of elemental carbon (EC), organic carbon (OC), polycyclic aromatic hydrocarbons (PAHs), the soluble organic fraction (SOF), and trace metals. This paper summarizes most aspects of diesel particulate emissions for the benefit of active researchers in the field and underlines the importance of particulate emission reduction from the CI engines. Diesel combustion generates particles with enormous long-chain aggregates of smaller sizes and immature soot particles. Low-temperature combustion (LTC) modes and oxygenated fuels reduce the soot emissions and generate compact/clustered aggregates. Oxygenated fuels in CI engines produce more nucleation mode particles (NMPs) and high-reactivity soot aggregates. Higher trace metal concentrations were observed in diesel origin particulates than biofuel origin particulates. Biodiesel origin particulates possess higher mutagenicity and carcinogenicity because of nitro-PAHs. Transient engine operations cause higher particulates than steady-state engine operations.

The quality of the fuel supply process is the main criterion for ensuring the required indicators of efficiency and environmental friendliness of a diesel locomotive. The electronic control system of the ESUVT.01 type for D50 type diesel (6 CHN 31.8/33) for fuel supply control is produced by JSC Penzadizelmash developed in LLC PPP Dieselavtomatika (Saratov) is presented. Optimizing the phase of the beginning of fuel supply – the advance angle of fuel injection (AAFI) shows the possibility of a significant improvement in fuel efficiency and toxicity of diesel exhaust gases. To assess the effect of the AAFI on the diesel locomotive performance, its experimental studies were carried out. The object of bench tests was a diesel generator set of type 1-PDG4D with the specified diesel and with a traction generator MPT-84/39. During the tests, the dependencies of diesel indicators on the AAFI were obtained. The necessity of optimizing the values of the AAFI in accordance with the engine operating mode is confirmed. Optimized values of the AAFI are obtained in the modes of diesel characteristics. The toxicity indicators of diesel exhaust gases and fuel efficiency with optimized characteristics of the AAFI are determined.
