Meeting the requirements of heavy-duty engine emissions regulations is a challenge for all engine manufacturers. Since the introduction of Exhaust Gas Recirculation (EGR) in medium and heavy-duty diesel engines, these systems have become more sophisticated and tightly integrated with emission control systems. This 2-day seminar will explore the advantages and disadvantages of EGR and the most effective implementation of various EGR systems. This seminar will begin by defining EGR and why it is used in diesel engines, along with an explanation of the mechanisms by which EGR is able to reduce NOx.

As diesel engines become more popular, a fundamental knowledge of diesel technology is critical for anyone involved in the diesel engine support industry. This course will explain the fundamental technology of diesel engines starting with a short but thorough introduction of the diesel combustion cycle, and continue with aspects of engine design, emission control design, and more. An overview of developing technologies for the future with a comprehensive section on exhaust aftertreatment is also included. The text, Diesel Emissions and Their Control, authored by Magdi Khair and W. Addy Majewski is included with the seminar.

Recent work has demonstrated the potential of gasoline-like fuels to reduce NOx and particulate emissions when used in Diesel engines. In this context, straight-run naphtha, a refinery stream directly derived from the atmospheric crude oil distillation process, has been identified as a highly valuable fuel. The current study is one step further toward naphtha-based fuel to power compression ignition engines. The potential of a cetane number 25 fuel (CN25), resulting from a blend of hydro treated straight-run naphtha CN35 with unleaded non-oxygenated gasoline RON91 is assessed. For this purpose, investigations are conducted on multiple fronts, including experimental activities at the injection test bed, in an optically accessible vessel and on a single cylinder engine. CFD simulations are also developed to provide relevant explanations.

Partially Premixed Combustion (PPC) is one of the promising combustion model with a high thermal efficiency and a low emission level, and also need a minimum modification of the engine hardware. To use PPC in a real production engine, the gas-exchange efficiency should also be included into analysis, the trade-off of the gas-exchange efficiency and net indicated thermal efficiency is investigated in this paper. The experiments results showed that the recipe of EGR as close to 50% to 55% as possible and the lambda close to 1.4 had the highest net indicated efficiency. This recipe was applied to a multi-cylinder engine from low load to high load. The results indicated that the highest gross indicated efficiency and net indicated efficiency of the experimental engine were 53.5% and 52.1% at 11.7 IMEPn, the highest brake efficiency was 44.3% observed at 17.8 IMEPn. The efficiency potential of this engine was discussed in the end.

This study investigates combustion and emissions of Jet-A in an indirect injection (IDI) compression ignition engine and a direct injection (DI) compression ignition engine at 4.5 bar IMEP and 2000 RPM. The Jet-A was blended with ULSD that resulted in 75%Jet-A and 25% ULSD#2 by mass. Both engines were instrumented with Kistler pressure sensors in the main chamber and the IDI engine had a second pressure sensor in the pre-chamber. Combustion properties and emissions from both engines using the 75% jet-A blend (75Jet-A) were compared to a baseline test of Ultra Low Sulfur Diesel #2 (ULSD). The ignition delay was shorter when running on 75Jet-A compared to ULSD in the DI engine. For ULSD, the ignition delay was 1.8 ms and it reduced to 1.7 ms when operating on 75Jet-A (difference of 6%). In the IDI engine the ignition delay for both fuels was 2.3 ms based off the gross heat release in the Pre-Chamber.

The development of present day spark ignition (SI) engines has imposed higher demands for its on-board ignition systems. Different spark voltage and current patterns are required for those SI engines to help initiate ignition and to improve the energy transfer efficiency from the system’s primary side to its secondary side. Proper design of the ignition system circuit is required to achieve certain spark performances, the lack of an arranged instructional document made it quite inconvenient for designers to develop a spark ignition system which can perform up to the required criteria. In this paper, the authors studied the relation between spark electric characteristics and different inductive spark ignition circuit parameters with the help of a simplified circuit model. The circuit model catches the principle behavior of the spark ignition system and uses a diode model to approximate the spark plug.

Upcoming type approval regulations will force to optimize aftertreatment system to reduce emissions looking for lack of fuel penalty. Despite advances in purely aftertreatment aspects, the performance of the diverse aftertreatment devices is very dependent on the operating temperature. This makes them rely on the engine design and calibration because of the imposed turbine outlet temperature. The need to reach target conversion efficiency and to complete regeneration processes requires controlling additional parameters during the engine setup. For that reason, exploring the potential of different solutions to increase inlet aftertreatment temperature is becoming a critical topic. Nevertheless, such studies cannot be tackled without considering concerns on the engine fuel consumption. In this paper, the influence of several design parameters is studied by modelling approach under steady state operating conditions in a Diesel engine.

Several application developers are currently faced with the problem of moving a complex system from a single-core to a multicore platform. The problem encompasses several issues that go from modeling issues (the need to represent the system features of interest with sufficient accuracy) to analysis and optimization techniques, to the selection of the right formulations for constraints that relate to time. We report on the initial findings in a case study in which the application of interest is a fuel injection system. We provide an analysis on the limitations of AUTOSAR and the existing modeling tools and we discuss applicable optimization methods and analysis algorithms.

UV-visible digital imaging and 2D chemiluminescence were applied on a single cylinder optically accessible compression ignition engine to investigate the effect of different alcohol/diesel fuel blends on the combustion mechanism. The growing request for greenhouse gas emission reduction imposes to consider the use of alternative fuels with the aim of both partially replacing the diesel fuel and reducing the fuel consumption. To this purpose, the use of ABE (Acetone–Butanol–Ethanol) fermentation could represent an effective solution. Even if the different properties of alcohols compared to Diesel fuel limit the maximum blend concentration, low blend volume fractions can be employed for improving combustion efficiency and exhaust emissions.
