To meet the exhaust emission requirements implemented by U. S. EPA, UIC, IMO and others, it is not only necessary to develop new engines and combustion systems that meet these requirements, but also to update existing engines with low emission technologies. The electronic common rail fuel system has positive advantages over conventional methods, including increased fuel efficiency and limited exhaust emissions and smoke. Since only one compact high pressure common rail pump is needed, instead of one jerk pump per cylinder, to adapt to the existing engine designs, the only challenge is to fit the injectors into the existing cylinder heads. This publication evaluates the potential impacts of this new technology on emissions and fuel consumption. It outlines component design in detail and illustrates some specific production issues. One unique retrofit proposal, focused towards existing engines, will be a low emissions kit supplied by L’Orange and Fluid Mechanics for application on EMD 645 and 710 engines. These two-stroke engines have been built since 1965 and more than 50,000 exist today, mostly on large locomotives in the NAFTA region. The retrofit kit is backed by L’Orange’s knowledge and experience in the design and production of over 150,000 common rail fuel injectors supplied to MTU and Detroit Diesel series 4000 engines.

Tis paper provides an overview of possibilities for determining tractor’s engine load, fuel consumption and exhaust emissions in real operating conditions. Theuse of accumulated database in tractor’s electronic control modules for the analysis of engine load, fuel consumption and exhaust emissions is analysed. The methodology for analysis of engine power, speed and exhaust emissions’ dependencies, also for analysis of engine exhaust emissions is presented. Tis paper presents testing results of the unit combined of tractor “Massey Ferguson MF 6499” and drilling machine “Vaderstad Rapid” by engine load, fuel consumption and exhaust emissions. Drilling process time, engine load, fuel consumption and exhaust emission components’ distribution are presented in different engine speed and cyclic fuel injection modes. Test results are analysed separately for technological drilling and work processes at the headland. In the technological process of drilling, if the tractor engine speed and, correspondingly, the transmission gear ratio were reduced to get the set working speed, fuel consumption decreased, CO and CO2 emissions varied slightly, but the NOx increased significantly. Significant part of exhaust emissions occurred at headlands. The conclusion is that the fuel consumption and exhaust emissions, including harmful components, can be reduced only by complex optimization of technological processes and tractor operating modes.

Concentration Ratios

Due to the recent global increase in fuel prices, to reduce emissions from ground transportation and improve urban air quality, it is necessary to improve fuel efficiency and reduce emissions. Water, methanol, and a mixture of the two were added at the pre-intercooler position to keep the same charge and cooling of the original rich mixture, reduce BSFC and increase ITE, and promote combustion. The methanol/water mixing volume ratios of different fuel injection strategies were compared to find the best balance between fuel consumption, performance, and emission trends. By simulating the combustion mechanism of methanol, water, and diesel mixed through the Chemkin system, the ignition delay, temperature change, and the generation rate of the hydroxyl group (−OH) in the reaction process were analyzed. Furthermore, the performance and emission of the engine were analyzed in combination with the actual experiment process. This paper studied the application of different concentration ratios of the water–methanol–diesel mixture in engines. Five concentration ratios of water–methanol blending were injected into the engine at different injection ratios at the pre-intercooler position, such as 100% methanol, 90% methanol/10% water, 60% methanol/40% water, 30% methanol/70% water, 100% water was used. With different volume ratios of premixes, the combustion rate and combustion efficiency were affected by droplet extinguishment, flashing, or explosion, resulting in changes in combustion temperature and affecting engine performance and emissions. In this article, the injection carryout at the pre-intercooler position of the intake port indicated thermal efficiency increase and a brake specific fuel consumption rate decrease with the increase of water–methanol concentration, and reduce CO, UHC, and nitrogen oxide emissions. In particular, when 60% methanol and 40% water were added, it was found that the ignition delay was the shortest and the cylinder pressure was the largest, but the heat release rate was indeed the lowest.

Road transport holds for the largest share in the freight transport sector in Europe. This work is carried out by heavy vehicles of various types. It is assumed that, in principle, transport should take place on the main road connections, such as motorways or national roads. Their share in the polish road infrastructure is not dominant. Rural and communal roads roads are the most prevalent. This fact formed the basis of the exhaust emissions and fuel consumption tests of heavy vehicles in real operating conditions. A set of vehicles (truck tractor with a semi-trailer) meeting the Euro V emission norm, transporting a load of 24,800 kg, was selected for the tests. The research was carried out on an non-urban route, the test route length was 22 km. A mobile Semtech DS instrument was used, which was used to measure the exhaust emissions. Based on the obtained results, the emission characteristics were determined in relation to the operating parameters of the vehicles drive system. Road emission, specific emission and fuel consumption values were also calculated.

To enhance the effectiveness of intercity passenger rail service in mitigating exhaust emissions in California, the California Department to Transportation (Caltrans) included limits on exhaust emissions in its intercity locomotive procurement specifications. Because there were no available exhaust emission test data on which emission reduction goals could be based, Caltrans funded a test program to acquire gaseous and particulate exhaust emissions data, along with smoke opacity data, from two state-of-the-art intercity passenger locomotives. The two passenger locomotives (an EMD F59PH and a GE DASH8-32BWH) were tested at the Association of American Railroads Chicago Technical Center. The EMD locomotive was eqiupped with a separate Detroit Diesel, Corporation (DDC) 8V-149 diesel engine used to provide 480 V AC power for the trailing passenger cars. This DDC engine was also emission tested. These data were used to quantify baseline exhaust emission levels as a challenge to locomotive manufacturers to offer new locomotives with reduced emissions. Data from the two locomotive engines were recorded at standard fuel injection timing and with the fuel injection timing retarded 4 deg in an effort to reduce NOx emissions. Results of this emissions testing were incorporated into the Caltrans locomotive procurement process by including emission performance requirements in the Caltrans intercity passenger locomotive specification, and therefore in the procurement decision. This paper contains steady-state exhaust emission test results for hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), and particulate matter (PM) from the two locomotives. Computed sulfur dixoide (SO2) emissions are also given, and are based on diesel fuel consumption and sulfur content. Exhaust smoke opacity is also reported.

For spark ignition engines, the fuel-air mixture preparation process is known to have a significant influence on engine performance and exhaust emissions. In this paper, an experimental study is made to characterize the spray characteristics of an injector with multi-disc nozzle used in the engine. The distributions of the droplet size and velocity and volume flux were characterized by a PDA system. Also a model of a 4 cylinder multi-point fuel injection engine was prepared using a fluid dynamics code. By this code one-dimensional, unsteady, multiphase flow in the intake port has been modeled to study the mixture formation process in the intake port. Also, one-dimensional air flow and wall fuel film flow and a two-dimensional fuel droplet flow have been modeled, including the effects of in-cylinder mixture back flows into the port. The accuracy of model was verified using experimental results of the engine testing showing good agreement between the model and the real engine. As a result, predictions are obtained that provide a detailed picture of the air-fuel mixture properties along the intake port. A comparison was made on engine performance and exhaust emission in different fuel injection timing for 2600 rpm and different loads. According to the present investigation, optimum injection timing for different engine operating conditions was found.

Diesel engines are widely used as driving forces in vehicles and industry due to fuel efficiency and high output power. The wide use of diesel engines triggers an increase in fuel consumption and exhaust emissions that are harmful to health. Jatropha is a renewable fuel as a solution to increase fuel consumption. However, the high viscosity and low calorific value result in reduced performance and increased exhaust emissions. Butanol has a high oxygen content and cetane number and low viscosity compared to diesel and jatropha. Addition of butanol is possible to reduce the decrease in performance and exhaust emissions of diesel engines. this study evaluates the effect of butanol on reducing Isuzu 4JB1 diesel engine direct injection emissions. Percentage of blend used 70/30/0, 65/30/5, 60/30/10, and 55/40/15 based on volume. Tests are carried out at 2500 constant turns with a loading of 25% to 100% using the EGR system. The experimental results showed the presence of butanol caused a decrease in soot emissions produced by diesel engines

Wouldn’t it be nice to have plug and play technology for your boilers just like on your home computer? Wouldn’t it be great if this technology could give you instant and measurable reductions of 5 percent or more in fuel consumption? Well, in the modern era, this technology has arrived. A small Romanian company has developed a technology that treats combustion air that significantly increases fuel efficiency and lowers emissions on furnaces and boilers by interacting with the fuel at the combustion stage. This technology has the potential to reduce emissions of CO2 by 2–20%, NOx by 5–30%, SOx by 20–60% and emissions that negatively affect human health like acid mists (SO3), dioxins, benzenes, and VOC by as much as 90%. With over a million hours of testing on over 100 boilers and furnaces this economical technology holds great promise. The best part of the technology is that there is limited capital investment or operational costs, and use of the specialty aerosol injection will reduce wear and corrosion in your combustion box regardless of the fuel burned. It reduces costs across the board. Avogadro Environmental Corporation in Easton, PA is working with our partners, Opris Engineering and Kubik in Romania to make this technology available in the United States. The technology has a long proven record of performance and has been fully tested in the U.S. for efficiency improvements and emissions reductions. The technology has received the support of USEPA and state agencies. We are looking for plant operators interested in reducing their emissions and at the same time saving 5–25% in operating and maintenance costs. We just completed two full scale tests of the technology here in the US. The first site was a 90-day test at a 450 MMBtu/hr waste coal-fired electric utility boiler in Pennsylvania. The second site was a 60-day test at a 1,500 MMBtu/hr coal-fired electric utility boiler in the Southeast US.
