Hybrid powertrains have been on the market for more than a decade and have become one of the most successful alternative powertrains available today. More than a million hybrids are sold globally per year, primarily in Japan and the US. Some OEMs estimate that up to 80% of their light-duty vehicles may require some level of hybridization to meet upcoming CAFE regulations in the United States. Hybrids are also starting to make inroads into markets in Europe, and have recently been introduced to Chinese and Indian markets, among others. Basic information on hybrids is scattered among information...

Recent legislation has been enacted requiring unprecedented reductions in greenhouse gas emissions, and thus improved fuel efficiency, from internal combustion engines. The aggressive rate of improvement in fuel consumption mandated by this legislation has resulted in the proposal of more exotic combustion strategies than have previously been considered for serial production. The new combustion strategies that are being considered for near term applications can result in substantially different operating environments and thus the required performance of the emission control system. To deliver the most efficient engine system for each application, the impact of the combustion strategy on emission control system requirements must be taken into account when selecting the combustion strategy for production to ensure the benefits of the combustion strategy are not offset by penalties associated with treating exhaust emissions. This discussion will present data on the impact of novel combustion strategies on the operating environment for the emissions control system.

In-cylinder blending of gasoline and diesel to achieve reactivity controlled compression ignition (RCCI) has been shown to reduce NOX and particulate matter emissions while maintaining or improving brake thermal efficiency as compared to conventional diesel combustion. While RCCI operation has been shown to produce significant reductions in NOx and soot emissions, unburned hydrocarbons and CO emissions tend to increase compared to diesel combustion. This presentation discusses the current research into exhaust aftertreatment opportunities and challenges of proposed multi-mode diesel/RCCI operation where an engine would switch to diesel operation in areas outside the RCCI operating window.

In light of the existing and future vehicle fuel economy targets along with the challenge of future emissions legislation, significant potential has been shown for gasoline engine efficiency improvements. Similarly, many manufacturers have presented hybrid, range extended or electric vehicles. As such, the question arises: what place does the Diesel engine have in the future passenger car product portfolio and what is the most appropriate technology including electrification?

Abstract This paper discusses the design elements for a wet clutch system to successfully meet the requirements of today's motorcycle market. You can find new design ideas regarding how to realize important and critical clutch performance features such as torque boost, coast torque reduction (anti-hopping function), reduced actuation force, reduced drag torque, optimized weight, and/or optimized product cost. Most of these functions and features can be implemented in a modular clutch kit in which many of the parameters can be adapted with a minor design change of just a few components.

Abstract Using the PULSE platform for vibration analysis, which has been developed as an advanced solution for vibration measurements, the Robust Diagnostic Concept (RDC) was elaborated. The PULSE setup is designed to aid in fault diagnosis of a vehicle gearbox - the main part of a vehicle powertrain. Time Domain, Continuous Wavelet Transformation Technique (CWT), FFT and order analysis measurements are used for detection of an artificial pitting defect in a gear by tracking the gearbox response at accelerated speed and different loads. The test stand is equipped with three dynamometers; the input dynamometer serves as the internal combustion engine, the output dynamometers introduce the load on the flanges of the output joint shafts. The pitting defect is manufactured on the tooth side of the fifth speed gear on the intermediate shaft. The effect of temperature on the vibration measurements was also investigated to study its impact on the fault diagnosis. The presented concept has an important application in the field of mechanical fault diagnosis.

Modern vehicles are becoming increasingly complex – partially due to the growing requirement of transmissions that need optimisation of the gearshift process – examples being automated conventional and automatic transmissions, as well as double clutch and continuous variable transmissions (CVT). This increasing variety of configurations leads to complex development scenarios, that can manifest themselves as problematic issues affecting sensitive shift procedures – for example, a down-shift manoeuvre, that needs to be calibrated to provide seamless transition between ratios To assist in solving these problems, AVL has developed a tool chain and methodology, using powerful system architecture, to reproduce measure and model the problematic symptoms. In a particular case, the coast down shift from 3 to 2, in an automatic transmission with a high number of gears. One of the major tasks was to identify the quality problems that occur during a specific coast down shift manoeuvre whilst driving the vehicle on the road.

Predicting the temperature distribution within a gearbox under operating conditions is a challenging task. This is due to the unsteady multiphase flow of the oil, local heat generation sources between the intermeshing gears and within the bearing, and the complex external airflow pattern surrounding the casing. Geometrical details within the gearbox, for example small gaps and features, as well as detailed cooling fins structure sounding the casing add to the modeling challenges. Complexities also arise due to the drastically different time scales representing the highly transient flow within the gearbox and the near steady external airflow removing that thermal load. For example, the gearbox needs minutes to reach its steady state temperature which represents tens of thousands of revolutions of the gears. The current work represents a methodology for modeling this multi-scale problem. A generic four-speed gearbox is considered. First, the detailed isothermal multiphase flow of the oil is modeled using the volume of fluid (VOF) technique to predict the splashing pattern, oil coverage and churning losses.
