Emissions Of Harmful Substances

The purpose of this work is to consider the requirements for emissions of harmful substances of diesel engines by selecting design and adjustment parameters that determine the organization of the workflow, and the exhaust gas cleaning system, taking into account the reduction of fuel consumption. Design elements and geometric characteristics of structures for a turbocharged diesel engine of Д-245 series produced by JSC HMC Minsk Motor Plant (4ЧН11/12.5) with a capacity of 90 kW equipped with an electronically controlled battery fuel injection have been developed: exhaust gas recirculation along the high pressure circuit, shape and dimensions of the combustion chamber, the number and angular arrangement of the nozzle openings in a nozzle atomizer, and inlet channels of the cylinder head. Methods for organizing a workflow are proposed that take into account the shape of the indicator diagrams and affect the emissions of nitrogen oxides and dispersed particles differently. Their implementation allows us to determine the boundary ranges of changes in the control parameters of the fuel supply and exhaust gas recirculation systems when determining the area of minimizing the specific effective fuel consumption and the range of studies for the environmental performance of a diesel engine. The paper presents results of the study on the ways to meet  the requirements for emissions of harmful substances, obtained by considering options for the organization of working processes, taking into account the reduction in specific effective fuel consumption, changes in the average temperature of the exhaust gases and diesel equipment. To evaluate these methods, the following indicators have been identified: changes in specific fuel consumption and average temperature of the toxicity cycle relative to the base cycle, the necessary degree of conversion of the purification system for dispersed particles and NOx. Recommendations are given on choosing a diesel engine to meet Stage 4 emission standards for nitrogen oxides and dispersed particles.

This study presents the use of bio-solution and nano-Titanium dioxide (TiO2) based additives for dosing in diesel and palm biodiesel (B5). The aim of this work is to enhance the performance of a direct injection (DI) engine and to simultaneously reduce the exhaust gas emissions. The basic properties such as kinematic viscosity, specific gravity, flash point, fire point, and carbon residue of the test fuels were measured and accepted in ASTM standards. Overall, diesel-bio-solution and diesel-TiO2 blends show the lower break specific fuel consumption by 13% and 10%, respectively and the lower exhaust gas emissions, as compared with diesel. B5-bio-solution blend provides the break specific fuel consumption decreased by 1.68%, while exhaust emissions were effectively increased in comparison with B5 fuel.

Gas Recirculation

AbstractNOx emission is one of the major sources for health issues, acid rain and global warming. Diesel engine vehicles are the major sources for NOx emissions. Hence there is a need to reduce the emissions from the engines by identifying suitable techniques or by means of alternate fuels. The present investigation deals with the effect of Exhaust Gas Recirculation (EGR) on 4S, single cylinder, DI diesel engine using plastic oil/Diesel blends P10 (10% plastic oil & 90% diesel in volume), P20 and P30 at various EGR rates. Plastic oil blends were able to operate in diesel engines without any modifications and the results showed that P20 blend had the least NOx emission quantity.

The article presents the tests of the engine Valmet 320 DS installed in the teststand "Schenck Dynas3 LI 250". For these tests biodiesel produced by JSC Rapsoila was used. The test was carried out causing the engine speed to 2600 rpm and loading gradually to maximum. Torque (Te), engine speed (ne), fuel consumption (Bf), the pressure in the cylinder (Pe) and exhaust gas CO, CO2, O2, HC, NOx were measured. Initially, measurements were carried out using biodiesel (RME). After that, biodiesel was added with the additive Valvoline VPS HD Diesel System Complete keeping a ratio of 100:1. In order to evaluate the effects of additives the engine was working two hours using biodiesel and additive mixture. After two hours the measurements were repeated loading the engine in the same mode. The work presents the results of tests carried out.

And Performance

Due to fast depletion of fuel and for the huge demand of various engine fuels in large sectors and power generation, thse biodiesel which is derived from biological wastes can be a substitute of pure diesel oil. Diesel engine has the benefits of low fuel consumption, high potency, smart economical and dynamic performance. However at the identical time, the diesel engine has high NOx and soot emissions. And these two sorts of emissions provides a trade-off relationship which can bring difficulties to satisfy the necessities of emission rules of NOx and soot. This particular paper primarily reviews regarding using of preheated bio-diesel that contains 20 percentage of pure sunflower oil (biological name-Helianthus annuus) and analyses its performance characteristics for selected blend with completely variable loads. Various experiments were carried out by employing a four stroke single cylinder, direct injection, water cooled diesel engine with suitable specifications. Helianthus oil is mixed with bio diesel for fast burning inside the engine cylinder and by doing so , the Cetane number is quite high that leads to the ignition delay shorter. Therefore the overall content is preheated somewhat in order to lift its temperature so as to boost the burning process. Incorporating to this , it reduces the various emissions such as NOx, CO and smoke capacity by 2% to 3%. Various parameters are required to outline the analysis of combustion and performance characteristics of the test fuel like brake thermal efficiency(BTE),basic specific fuel consumption(BSFC), basic specific energy consumption (BSEC),temperature of the exhaust gas and emissions like NOx, unburn hydrocarbons(HC), carbon monoxide(CO) and smoke were carried out in the specified engine
