Abstract Global concerns over pollution have led to increasingly strict emissions legislation targeting small engines, which currently pollute at a much greater level than modern multi-cylinder automotive engines. Closed-loop control may be required to meet many future legislation requirements; however, such systems can be impractical due to high added component costs. A necessary component for closed-loop engine control is an oxygen sensor. Existing automotive oxygen sensors are too large, require too much power, and are far too expensive to be suitable for the vast majority of the global small engine applications; therefore, some manufacturers have developed smaller and/or unheated versions based on their existing sensors to meet this emerging need. The ability to miniaturize resistive based sensors well below that of traditional Nernst (zirconia based) oxygen sensors affords the opportunity to meet future emissions standards with less of an impact on cost.

Abstract The market potential for products such as scooters and small motorcycles is already self-sustaining. However, other applications for small engines can be more fragmented with a wide variety of requirements for the engine control unit. Consequently, the engine control unit can be designed to accommodate more features than are necessary for a given application to cover a broader market. The flip side of this approach is to design the engine control unit for a limited application reducing the market size. Neither approach creates a cost efficient product for the producer. It either supplies the market with an electronic control unit that has features not being utilized (wasted costs) or a unit that has limited capabilities reducing the economies of scale (higher costs). When these designs are developed using discrete components these inefficiencies are exacerbated.

Abstract This paper proposes a novel engine starter system composed of a small-power electric motor and a simple mechanical valve train. The system makes it possible to design more efficient starters than conventional systems, and it is especially effective to restart engines equipped with idling stop systems. Recently, several idling stop systems, having intelligent start-up functions and highly-efficient generate capabilities have been proposed for motorcycles. One of challenges of the idling stop systems is the downsizing of electric motors for starting-up. However, there are many limitations to downsize the electric motors in the conventional idling stop systems, since the systems utilize the forward-rotational torque of the electric motors to compress the air-fuel mixture gas in the cylinders.

Abstract The proposed paper is on electrical energy conservation in a two wheeler. Electrical energy generation adds a 12% load torque on an engine and hence saving electrical energy would ultimately reduce the consumption of fuel. Load Control Module (LCM) is a single intelligent device which is placed in between electrical energy generation and consumption. The module controls and distributes energy to the corresponding loads depending on parameters like battery voltage, engine RPM, overhead light illumination levels and load usage time. The module prioritizes battery charging for prolonging the life of the battery. The Module has a microcontroller and load drivers and it is programmed with a novel algorithm for prioritization and energy distribution with respect to input conditions.

Integrated Vehicle Health Management: Implementation and Lessons Learned is the fourth title in the IVHM series published by SAE International. This new book introduces a variety of case studies, lessons learned, and insights on what it really means to develop, implement, or manage an integrated system of systems. Integrated Vehicle Health Management: Implementation and Lessons Learned brings to the reader a wide set of hands-on stories, made possible by the contribution of twenty-three authors, who agreed to share their experience and wisdom on how new technologies are developed and put to work. This effort was again coordinated by Dr. Ian K. Jennions, Director of the IVHM Centre at Cranfield University (UK), and editor of the previous books in the series.

This document describes the Client Adaptation Element (CAE), the set of functions that provides access and aggregation capability for the WDM LAN, within the SAE AS5659 WDM LAN specifications document family. In the WDM LAN, the CAE fits in between the Optical Backbone, which provides transmission of data over the transparent network, and the clients which the network serves. The complexity of the CAE depends on the types and number of clients.

AS5659/3
This document describes network management and control facilities for the WDM LAN, within the SAE AS5659 WDM LAN specifications document family. Unlike like point-to-point solutions, networks require a control plane to allocate the shared network resources and a management plane which provides a disciplined approach to configuring and monitoring the network. Within a Wavelength Division Multiplexed (WDM) environment, management and control provides wavelength selection and routing for traffic that is processed. The extent of network management and control depends on the design of the network, and can range from hardwired wavelengths to dynamic wavelength allocation with damage recovery.

AS5659/1
This document provides a specification for the WDM Optical Backbone Network (OBN) within the SAE AS5659 WDM LAN specifications document family. The specification applies to any optical network which uses Wavelength Division Multiplexing (WDM) in any optical media, and describes a transparent optical network that contains optical components (i.e. without Optical-to-Electrical conversion). The specification describes optical network elements (ONE) that perform optical transport, optical add/drop, optical amplification, optical routing, and optical switching functions. Performance limits are given for conforming optical signal interfaces and transfer functions for the ONEs, as well as architectures comprising combinations of them. This specification will enable network and systems engineers to design and use scalable and upgradable WDM based optical networks aboard mobile platforms.

The following subjects reflect the automotive environment and are based on good engineering practices and past ("lessons learned") experiences. Since it is impossible to be all inclusive and cover every aspect of quality and reliability, this document should be used as a basis for preparation of a more comprehensive and detailed checklist that reflects the accumulated "lessons learned" at a particular Company. It is not the intent of this document to give a lot of detail, only to point out the type of subjects that need to be investigated and acted upon.

Connected vehicles bring many benefits, helping both drivers and traffic managers. However, it can be difficult for traffic managers to analyze and use the enormous amounts of data collected when every vehicle constantly transmits speed, direction, and other data points. That’s prompting many groups to see how big data schemes can be adapted for the transportation industry.

Abstract The spray development of ethanol, gasoline and iso-octane has been studied in an optically accessible, spark-ignition direct-injection (SIDI) engine. The focus is on how fuel properties impact temporal and spatial evolution of sprays at realistic ambient conditions. Two optical facilities were used: (1) a constant-flow spray chamber simulating cold-start conditions and (2) a single-cylinder SIDI engine running at normal, warmed-up operating conditions. In these optical facilities, high-speed Mie-scattering imaging is performed to measure penetrations of spray plumes at various injection pressures of 4, 7, 11 and 15 MPa. The results show that the effect of fuel type on the tip penetration length of the sprays depends on the injection conditions and the level of fuel jet atomisation and droplet breakup.
