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.

ISO 26262: Road Vehicle - Functional Safety is now becoming a condition of compliance for doing business in the automotive sector. The Scope states: “ISO 26262 is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production passenger cars with a maximum gross vehicle mass up to 3,500 kg…" This course provides background for reading and applying the standard and explains its scope, the major differences from the general safety standard IEC 61508, and how the scope changes with the introduction of new systems.

Driven by the need for lower emissions, better fuel economy and higher efficiency, hybrid vehicles are appearing in many different configurations on today's roadways. While the powertrain components such as the drive motor, motor controller and cooling system are somewhat familiar to the automotive industry, the battery systems are a relatively unfamiliar aspect. This seminar will introduce participants to the concepts of hybrid vehicles, their missions and the role of batteries in fulfilling those requirements. Battery topics including limitations, trends in hybrid development, customer wants and needs, battery system development timelines, comparison of electrochemistries and safety will be examined.

Electric and hybrid vehicles are becoming more visible on today's roadways and the automotive companies are working hard to make these vehicles as transparent as possible to enhance consumer acceptance. The battery system forms a key part of any of these vehicles and is probably the least understood. With practically no moving parts the battery systems show no visible or audible warning of any latent dangers. This seminar will introduce participants to the risks encountered in handling high voltage battery systems and their component parts. With the understanding of these risks, the seminar will then address how to raise risk awareness and then methods of dealing with those risks.

Cold start is a critical operating condition for diesel engines because of the resultant pollutant emissions produced by the unstable combustion at lower temperatures. In this research work, a light-duty, turbocharged diesel engine equipped with a common rail injection system was tested on a transient engine testing bed for an investigation of the starting process in terms of engine performance and emissions. The engine (including engine coolant, engine oil and fuel) was soaked in a cold cell at -7°C for at least 8 hours before starting of the test. The engine operating parameters such as engine speed, air/fuel ratio and EGR rate were recorded during the tests. Pollutant emissions (HC, NOx and particles both in mode of nucleation and accumulation) were measured before and after DOC. The results showed that conversion efficiency of NOx was higher during acceleration period at -7°C start than the case at 20°C start. The reduction of NOx and THC by DOC was less during idle period at -7°C cold start.

Cold weather is a challenge for compression ignition engines. As Diesel fuel creates wax crystals and gel when temperature goes down enough (sometimes just below 0°C), it comes to plug the fuel filter and the fuel injection system, leading to undesirable effects like loss of power, engine stall after start or even engine not starting at all. Side effects like fuel feeding pump durability can also be linked to it. Moreover, it has been shown that BioDiesel, and especially FAME coming from Palm, Tallow or Used Kitchen Oil has negative impacts on vehicle cold flow operability. Literature has even identified the key fuel components which impact the cold flow properties. Fuel cold flow properties can be improved through additives, which can be already included in the fuel at the pump, or manually added by the driver. But, obviously this cannot be easily controlled on the field and car manufacturers cannot handle in advanced where the fuel fill-up will be done, nor the quality of the fuel fed in the vehicle tank.

Automotive engines especially turbocharged diesel engines produce higher level of emissions during transient operation than in steady state. Therefore, the study of engine transients has received increasing attention for meeting the new emission legislations. In order to improve understanding of the engine transients and develop advanced technologies to reduce the transient emissions, the engine researchers require accurate data acquisition and appropriate post-processing techniques which are capable of dealing with noise and synchronization issues. The objective of this study is to develop a methodology for the measurement and processing of data during transient engine tests concerning the noise in time-resolved data during the transient which requires proper filtering. A common practice in engine tests is ensemble averaging the data of a number of cycles for the steady state experiments but this method is not suitable for the transient cases. In this study, four alternative automated methods were implemented on in-cylinder pressure data of each individual cycle to compare and analyze the suitability of combustion diagnostic.
