Diesel emissions regulations have become much stricter over time, requiring advanced engine and aftertreatment technologies. Modern diesel engines use precise high-pressure fuel injection, exhaust gas recirculation, and particulate filters or catalysts to meet lower emission limits. Selective catalytic reduction using urea injection is also used to convert nitrogen oxides to harmless gases. Biodiesel can help meet emissions standards when used as intended but special considerations are needed to prevent fuel system and filter issues.
Emission Measurements of Various Biofuels using a Commercial Swirl-Type Air-A...JOACHIM AGOU
A joint university-industry research program funded by Rolls-Royce Canada, NSERC and CRIAQ is actually pursued at Université Laval to characterize the combustion performance of liquid (biodiesel blends) and gaseous (syngas blends) biofuels in terms of emissions & smoke and lean blow out. The final objective of the proposed research is to characterize the most promising liquid and gaseous novel biofuels for use in industrial gas turbines in order to reduce greenhouse gases and potentially operation costs. These combustion tests allowed the characterization of standard diesel fuel as a baseline plus two biodiesel blends as well as standard methane as a baseline plus ten syngas blends (CH4, H2, CO and CO2) in order to evaluate the emissions of the main pollutants (CO, CO2, NOx, UHCs and smoke). Combustor exit and wall temperature measurements were also taken to characterize adequately the boundary conditions for future CFD simulations. The flame was contained in a quartz tube combustor operating at ambient outlet conditions and the fuel was delivered through a commercial swirl-type, airblast dual fuel atomizer. The air mass flow rate was kept constant for all fuels to maintain the same pressure drop (ΔP) across the fuel injector while the fuel flow was varied to cover equivalence ratios from 0.5 to 1. A probe connected to a FTIR/FID/O2 gas analyzer system and a smoke filter was fixed to a 3D-axis traverse in order to sample combustion products in a cross pattern at the combustor exit. This way, concentrations of various emissions were obtained at five radial positions. Burned gases and wall temperatures were measured with thermocouples along the test rig. This paper reports the findings of these experimental tests and presents the comparisons of the biofuels with baseline fuels to identify some benefits of these novel biofuels while maintaining an acceptable overall combustion performance.
The oil analysis report is a vital tool for a smooth running operation. Going deeper than the report summaries and knowing how to analyze the oil analysis report can help prevent equipment breakdown and unnecessary equipment teardowns.

Dwon will review some of the most common tests run on industrial equipment and teach you how to read test reports. He will also walk you through marginal and critical reports and teach you how to decipher various alarms. You will walk away with an improved knowledge of oil analysis report interpretation.
Properly characterizing a lubricant deposit can provide insight into the cause of a problem and allow plants to make corrective actions, resulting in tremendous savings. This webinar will present a multitude of real-world case studies where this practice of deposit characterization has been used in the field. Attendees will learn how a unique deposit that is not detectable through normal varnish testing caused a million-dollar shutdown at a nuclear facility, about the creation of tar balls in a sensitive gas turbine, how black goo was generated in a critical gas compressor, among others.

Advanced technologies as "DOC, DPF, SCR" to reduce Diesel engines harmful em...Omar Qasim
Diesel engines play a dominant role in transport because of their lower fuel consumption and higher thermal efficiency. However, the high particulate matter (PM) emissions and high rat of the NOx emission of diesel engines also cause a series of environmental and social problems. several studies investigated the relationship between particulate matter emission and human health and found that 4.2 million deaths (7.6% of all global deaths) caused by outdoor fine particulate air pollution in 2015 and particulate matter (PM 2.5) was the fifth highest ranking risk factor for death in the world.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Editor's Notes
Most of you have seen this slide, which discloses the various technologies that are being applied to achieve Tier 2-4 emissions levels. I will only discuss the fuel system where the migration to common rail systems are a key leverage for achieving low emissions.
Injection pressure requirements for large engines have evolved from the stringent emissions requirements and a desire to achieve as low an in-cylinder NOx, smoke and particulate solution as possible. This is to reduced the burden on future aftertreatment systems. For Tier 2 and 3 we were able to avoid use of aftertreatment, but for Tier 4 it seems clear some aftertreatment will be required. HPCR is a necessary building block in the total system for emissions solutions. It offers improvements in NOx, fuel economy, smoke, noise, UHC, CO and particulate control that would not be available through conventional mechanical or electronic unit injection systems. The multiple injection events, injection rate control, and precision injection timing control over the life of the engine are critical to achieving and maintaining emissions without deterioration.

The multiple injection events, injection rate control, and precision injection timing control over the life of the engine are critical to achieving and maintaining emissions without deterioration.
This 6-sigma critical parameter flowdown is meant to illustrate how we try to tie the controlled properties of commodity diesel fuels to those properties that fuel system manufacturers required. The Red boxes are the ones most critical to us, and unfortunately are generally the least controlled by the refiners and fuel delivery infrastructure. And only through disciplined and expensive sampling can the fuel properties even be ascertained to be acceptable. These only are snapshots of the fuel quality and not representative of the total time history of fuel consumed by the engine. So for the most part, end customers get a wide range of fuel qualities, most within the broad specification of ASTMD975 or EN590 and outside North America and Europe the control of fuel quality is even less disciplined There are some notable exceptions -- certain areas like western Canada where the refiners of synthetic crude derived from tar sands seem to have excellent control over fuel quality.
Water in fuel can also aggravate HPCR wear through corrosion products that are as hard as hard particles. And they can serve as growth mediums for microorganisms that plug filters and create acids and ions that promote corrosion and deposits. Freezing of water in fuel is problematic during cold weather operation. Reaction of water concentrates of acids and bases to form organic soaps that plug filters is less well understood. Under extreme conditions these can plug injector orifices and nozzles. And lubricity can be drastically reduced with only 1000 ppm of water in fuel.
Highly refined S15 UltraLow Sulfur (ULSD) diesel fuel may have additive packs to improve lubricity and corrosion resistance, but these may lower interfacial surface tension on filter medias that make water removal more difficult. Fuel Water Separation is more challenging as biodiesel percentages increase, and solvency of biodiesel blends makes coated cellulose media less effective.
