Liquid fuel atomization and spray formation is the heart of the majority of stationary and mobile power generation machines that we rely on. This seminar focuses on the process of liquid atomization and spray formation and how it relates to fuel injection systems and emission of pollutants in modern engines. The seminar begins with background coverage of terminology, the purposes of liquid atomization and spray formation, and different designs of atomizers and nozzles employed in various industries. The focus is then directed to gasoline and diesel fuel injections, injector designs, and performance requirements for optimum engine operation with lowest possible emission of harmful pollutants.

Fuel composition has had to change with the advent of more stringent emission regulations. Reformulated gasoline (RFG), for example, is vastly different from gasoline of even ten years ago. Tightening regulations on diesel emissions will dramatically change both diesel fuel and engine design. This three-day seminar will review the fundamentals of motor fuels, combustion and motor power generation. The primary content of the course provides a basic introduction to the technology, performance, evaluation, and specifications of current gasoline, diesel, and turbine fuels. The first day of the course begins with a brief review of the evolution of motor fuel through 100 years of performance and specification.

Driven by the need for lower emissions, better fuel economy and improved drive quality, optimized powertrain calibrations are required for the many different vehicle configurations on today's roadways. While powertrain components such as the internal combustion engine, transmission, and hybrid electric powertrain are somewhat familiar to the automotive industry, the control theory, calibrations and system interactions between these components are a relatively unfamiliar aspect. This web seminar will introduce participants to the concepts behind optimized powertrain calibrations and how they impact fuel consumption, exhaust emissions, and vehicle performance.

Lubricating fluids are the lifeblood of modern engines, performing numerous vital functions from reducing system friction, temperature, and fuel consumption to minimizing tailpipe emissions. This comprehensive seminar covers the latest developments in lubricating fluids technologies and explores the relationships between lubricating fluids and emissions, after-treatment devices, bio-fuels, and fuel economy. Fundamentals of crankcase lubrication, including the properties and performance requirements of global base stocks and lubricants will be covered. The seminar will further explore the need for lubricating systems to possess thermal and oxidative stability sufficient to withstand the rigors of low-heat-rejection, high performance diesel engines or other modern engines equipped with various emission control devices.

In your profession, an educated understanding of internal combustion engines is required, not optional. This two-day technology survey seminar covers the most relevant topics - ranging from the chemistry of combustion to the kinematics of internal components of the modern internal combustion engine - for maximum comprehension. Attendees will gain a practical, hands-on approach to the basics of the most common designs of internal combustion engines, as they apply to the gaseous cycles, thermodynamics and heat transfer to the major components, and the design theories that embody these concepts.

The path to commercialization of plug-in hybrids is likely to require complex interactions between OEMs, battery manufacturers, electric utilities, and government, yet the plug-in hybrid is a still-developing technology. How do plug-in hybrids (PHEVs) differ from conventional hybrids? What are the advantages and challenges for vehicle manufacturers, public utilities, energy and environmental concerns, and end-users? What is the current state of plug-in hybrid development? Those unfamiliar with PHEV or vehicle-to-grid (V2G) technology, yet whose job will be impacted by plug-in hybrid vehicles in the future, will benefit from this two-hour web seminar.

Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%. This web seminar will explore turbocharging for gasoline and diesel (heavy and light duty) engines, including the fundamentals of turbocharging, design features, performance measures, and matching and selection criteria.

Storing hydrogen is one of the major issues concerning its utilization on board vehicles. A promising solution is storing hydrogen in the form of ammonia that contains almost 18% hydrogen by mass and is liquid at roughly 9 bar at environmental temperature. As a matter of fact, liquid ammonia contains 1.7 times as much hydrogen as liquid hydrogen itself, thus involving relatively small volumes and light and low-cost tanks. It is well known that ammonia can be burned directly in I.C. engines, however a combustion promoter is necessary to support and speed up combustion especially in the case of high-speed S.I. engines. The best promoter is hydrogen, due to is opposed and complementary characteristics to those of ammonia. Hydrogen has high combustion velocity, low ignition energy and wide flammability range, whereas ammonia has low flame speed, narrow flammability range, high ignition energy and high self-ignition temperature. Another important point is the possibility to obtain hydrogen on board from ammonia, by means of a catalytic reactor.

Biodiesel is a renewable, biodegradable, and nontoxic alternative diesel fuel with a potential to reduce the life cycle CO2 emission. Biodiesel contains oxygen, therefore the smoke emissions is lower than that of the conventional diesel fuel. Several technical papers express that among the various kinds of biodiesel, coconut oil methyl ester (CME) has lower HC, CO, NOx and smoke emissions compared to other biodiesels, such as rapeseed oil methyl ester and soybean oil methyl ester because CME contains medium chain saturated FAME (methyl caprylate, methyl caprate) with lower boiling point and kinematic viscosity, compared to long chain saturated FAME (methyl laurate, methyl palmitate et al.) and the oxygen content of CME is about 4 mass% higher than that of other biodiesels. Generally biodiesel is made from vegetable oil and methanol by transesterification. However, biodiesel can be made by using other alcohols, such as ethanol and butanol which are bio-alcohols. Biodiesel made from bio-alcohol has higher lifecycle CO2 reduction compared with that from methanol.

The objective of this study is to understand the fundamental spray combustion characteristics of fatty acid methyl ester, FAME, mixed with diesel oil, called bio diesel fuel hereafter. To examine the phenomena in detail, diesel spray flame formed in a constant volume high pressure vessel was visualized and the flame temperature and the soot concentration were analyzed by two color method of luminous flame. The composition of combustion gas was measured by a Gas analyzer to quantify the concentration of NOx and CO. The ambient high-pressure and high-temperature conditions inside the constant volume vessel were achieved by the combustion of hydrogen in an enriched oxygen and air mixture. The composition of the mixture was such that the oxygen concentration after hydrogen combustion was approximately 21% by volume. Following hydrogen combustion, fuel was injected into the vessel at the time when the ambient pressure reached the expected value, and the spray combustion was then examined. The fuel injection system used in the present study is an electronically controlled accumulator type fuel injection system developed by the authors.
