Opis:
Introduction. Diesel oil is a mixture of hydrocarbons. These compounds are widely used in everyday life. Oral exposures are most often accidental and affect mainly children, but they also happen in adults. Oral ingestion may lead to aspiration of pulmonary alveoli which may cause necrotizing pneumonia. Aim. The aim of the study is to assess te severity of diesel oil intoxication on an example of a presented case. Methods. The analysis of the clinical patient history and review of available literature. Results. A 27 year old patient was admitted to the toxicology department due to accidental diesel poisoning. Patient drank a small amount diesel oil, then suffered nausea and vomiting, which resulted in aspiration of diesel to respiratory system. During hospitalization focal necrotizing pneumonia was diagnosed. Patient was treated with intensive specific pharmacotherapy. On the 11th day of stay, the patient was discharged with recommendation of control in the pulmonological and toxicological clinic and chest x-ray examination in order to diagnose the suspicious oval change discovered in the right lobe during hospitalization. Conclusion. First toxicity symptoms are non-specific, so well collected anamnesis is crucial. Complications of hydrocarbon ingestion can be a threat to patient’s life. Due to rarity of the problem, there are no clearly defined treatment guidelines

Opis:
Current and future air quality is a worldwide concern, which has resulted in both a continuous tightening of emissions legislation for vehicles and a parallel tightening of fuel specifications. The automotive and oil industry across the globe especially in EU, USA and Japan have in each case made considerable efforts to understand the relationship between vehicle emissions, urban air quality, engine technologies and fuels, and to meet the more and more stringent legislation. The supply of automotive fuels today is based almost entirely on petroleum.The quality requirements of diesel fuels become more and more stricter and it will continue in the next decades, because the clean engines need clean fuels. Therefore, fuels of low emission become significant factor in reducing toxic emission which pollutes the environment. With the introduce of low sulfur diesel fuel, the effect of sulfur become less significant. Other fuel properties such as aromatics content i.e. composition thus becomes more important. From this aspect it is investigated the affect of simultaneous addition of mono+-, di+ - and tri+-aromatics into low-sulfur diesel fuel. Obtained results show that aromatics composition has the effect on diesel exhaust emission.

Opis:
The article presents bench test results of a four-stroke, four-cylinder, naturally aspirated, DI diesel engine operating with neat JP-8 fuel (J) and its blends with Diesel fuel (D) in following proportions by volume: 90/10 (J+10D), 70/30 (J+D30), 50/ 50 (J+D50), 30/70 (J+D70), and 100% diesel fuel (DF). The purpose of the research was to analyse and compare changes occurred in the autoignition delay, combustion events, engine performance efficiency, emissions, and smoke of the exhaust when running on JP-8 fuel, jet-diesel fuel blends, and diesel fuel at a full (100%) engine load and speed of 1400 min–1 at which maximum torque occurs and rated speed of 2200 min–1. It was found that the start of injection (SOI) and the start of combustion (SOC) occurred earlier in an engine cycle and the autoignition delay decreased by 9.0% and 12.7% due to replacement of aviation JP-8 fuel with diesel fuel at a full load and the latter speeds. Maximum in-cylinder pressure was 6.8% and 4.0% higher when operating with diesel fuel, whereas brake thermal efficiency was 3.3% and 7.7% higher, and brake specific fuel consumption 2.8% and 7.0% lower when using fuel blend J+D50 compared with the respective values measured with neat JP-8 fuel. Emissions of nitric oxide (NO) and nitrogen oxides (NOx) were 13.3% and 13.1% higher from a straight diesel running at speed of 1400 min–1, and 19.0% and 19.5% higher at a higher speed of 2200 min–1. The carbon monoxide (CO) emissions and total unburned hydrocarbons (HC) decreased 2.1 times and by 12.3% when running with fuel blend J+D70 at speed of 2200 min–1 compared with those values measured with jet fuel. Smoke of the exhaust was 53.1% and 1.9% higher when using fuel blend J+D10 than that of 46.9% and 70.0% measured with jet fuel at speeds of 1400 and 2200 min–1. The engine produced 34.5% more smoke from combustion of fuel blend J+D70 at the low speed of 1400 min–1, but smoke converted to be 11.3% lower when operating at a higher speed of 2200 min–1.

Opis:
The most common chemical’s spills in typical transportation accidents are those with petroleum products such as diesel fuel, the consequence of which is an extensive pollution of the soil. In order to plan properly fuel recovery from the soil, it is important to gain information about the soil depth which may be affected by pollutant and to predict the pollutant concentration in different soil layers. This study deals with the impact of basic atmospheric conditions, i.e. air temperature and humidity on the diesel fuel migration through the soil. The diesel fuel was spilled into columns (L = 30 cm; D = 4.6 cm) filled with sandy and clay soil samples, and its concentrations at various depths were measured after 11 days under various air temperature (20 and 40°C) and relative humidity (30–100%) conditions. The effects observed were explained by understanding physical processes, such as fuel evaporation, diffusion and adsorption on soil grains. The increase in temperature results in higher fuel evaporation loss and its faster vertical migration. The relative humidity effect is less pronounced but more complex, and it depends much on the soil type.

Opis:
The types and action mechanism of depressant additions, which improves the properties of diesel fuels in low temperatures, were presented. The results of a sixteen different depressants influence on cloud point (CP) and cold filter plugging point (CFPP) of diesel fuels ONA without additions are given in following elaborate. The depressants were applied to samples of diesel fuel in concentration between 500 and 5000 ppm. The present paper shows correlation of diesel fuels ONA CFPP and ΔCFPP depression between depressants concentration. Only a part from the tested depressant additions has a significant impact on diesel fuel cloud filter plugging point at concentration recommended by their manufacturers. Moreover, some of the additions do not decrease the CFPP value. The depressants can be divided into three groups by their effectiveness: first, the ones which decreases greatly the CFPP (from 3 to 11 degrees) by adding only small amount of them (500 ppm), second, with almost no influence on CFPP values in smaller amounts (500 ppm) but reducing CFPP values in larger quantities (to 5000 ppm), third, with no influence on diesel fuels ONA CFPP even in large concentration. In conclusion, lowering the CFPP value depends on the kind of depressant and its concentration in diesel fuel and not on the diesel hydrocarbon composition with addition up to 7% of Fatty Acid Methyl Ester (FAME).

Article discusses issues concerning diagnosing and researching fuel unit injectors (UI). This fuel system has been taken off in automobiles but the problems with diagnosing and research is still actually. Motorized vehicles with fuel unit injector system were manufactured until 2010 but lorries are still producing. Only one automotive concern VW put in this system to motorized vehicles in Europe. The 1.9 TDI engines have PDE 1 (UI) and 1.4 TDI, 2.0 TDI engines have PDE 2 (UI). Unit injector is device which main tasks are spray and distribute fuel in combustion chamber of Diesel engine. Unit fuel injector is built with three sections: fuel injection nozzle complex, electromagnet unit and pump part. Injection nozzle complex is common mechanical one spring injector. That research is on check and eventually adjusts open pressure. Electromagnet units are non-dismantle and non-repair, but there is possibility dismantle and clean it. Electromagnet unit affects injection dosages and module BIP (being of injection period) unit fuel injection. The task of pump part is fuel damming until demanding values. The pump part makes up piston with and main body, spring and protect flat piece of metal. Theoretically, also this element is non-repair. Main unit fuel injector work parameters are injection dosages values and signal BIP. During fuel unit injectors research checks injection dosages with varies settings (rotation speed, injection time). These parameters are similar to engine work on idle speed (idle speed dosage), pilot dosage, middle and full load dosage.

Opis:
The article presents the test results of the single cylinder compression ignition engine with common rail injection system operating on biofuels and conventional diesel blends with hydrogen. Two types of liquid fuels were tested: blend of the 7% Rapeseed Methyl Ester (RME) with conventional diesel fuel and Neste Pro Diesel – blend of the 15% Hydrotreated Vegetable Oil (HVO), produced by Neste Oil Corporation with conventional diesel fuel. The purpose of this investigation was to examine the influence of the hydrogen addition to biofuels and diesel blends on combustion phases, autoignition delay, engine performance efficiency and exhaust emissions. Hydrogen fraction was changed within the range from 0 to 43% by energy. Hydrogen was injected into the intake manifold, where it created homogeneous mixture with air. Tests were performed at both fixed and optimal injection timings at low, medium, and nominal engine load. After analysis of the engine bench tests and simulation with AVL BOOST software, it was observed that increasing hydrogen fraction shortened the fuel ignition delay phase and it affected the main combustion phase. Moreover, decrease of carbon monoxide (CO), carbon dioxide (CO2) and smoke opacity was observed with increase of hydrogen amounts to the engine. However, increase of the nitrogen oxide (NOx) concentration in the engine exhaust gases was observed.
