In an attempt to improve the fuel economy and reduce the exhaust emissions of motorcycles, some manufactures have developed commercialized motorcycles equipped with automatic idling-stop and go (AISG) functionality. Even though research efforts devoted to the idling-stop strategy have demonstrated its effectiveness, motorcycles equipped with the AISG device are not popular because the general public still has some concerns about them. This paper aims to evaluate the benefits and feasibility of a commercialized motorcycle with AISG functionality with regard to the public's concerns about fuel economy and emission problems during engine restart transients. In order to verify the accuracy of the analytical results and control for variable driver characteristics, a motorcycle chassis dynamometer was used to recreate the urban driving pattern. Furthermore, the feasibility of fuel-saving and emissions improvement by adjusting fuel-injection signal of the engine control unit (ECU) during engine restart operation was also evaluated. The experimental results showed that the addition of the fuel-injection modulation plus idling-stop strategy can improve the fuel economy rate by up to 12.2% and reduce carbon monoxide (CO) emission by up to 36.95% in comparison with the non-idling stop case.

In an attempt to reduce exhaust emissions from transportation vehicles, the Taiwanese government plans to enact the "no idling emission" policy regarding motorcycles/scooters. Automatic Idling Stop and Go (AISG) technology is a simple low cost method in which the internal combustion engine is automatically powered off when the scooter stops and restarted when the driver wishes. However, due to dissimilarities between scooters and automobiles in terms of driving behavior and powertrain configuration, the AISG topology and control strategy as used in automobiles cannot be applied to scooters directly. This paper investigated the feasibility of applying the AISG control technique to scooters to enhance the system's security and reliability and address public concerns about AISG by analyzing riding behavior and security issues. The goal of this study was to demonstrate an AISG device, which included the development of a miniaturized AISG control module and control logic algorithm considering operative convenience and safety. Finally the developed AISG control module was installed in a four-stroke, electronic-fuel-injection (EFI) scooter, enabling us to perform an actual on-road test to verify the feasibility and reliability of the AISG control technology.

<p>Mesin yang berbasis <em>Electronic Fuel Injection</em> (EFI) banyak digunakan karena menghasilkan performa yang tinggi dengan konsumsi bahan bakar yang sedikit dan gas emisi buang rendah. Namun ketika kendaraan berbasis EFI sudah digunakan lebih dari 5 tahun biasanya akan mengalami penurunan kinerja motor bersin yang berpengaruh pada performa ataupun kecepatan kendaraan tersebut. Oleh karena itu harus dilakukan servis <em>tuning</em>untuk meningkatkan kinerja motor pembakaran dalam dengan cara menyetting (<em>Engine Control Unit</em>) ECU dari mobil tersebut agar menormalkan atau memperbaiki daya yang dihasilkan. Penelitian ini melakukan program remapping ECU dengan menggunakan software <em>BitEdit</em> yang diaplikasikan pada mesin I-VTEC<em>type</em> honda jazz. Berdasarkan data penelitian, setelah dilakukan <em>remapping </em>pada spesifikasi dasar terdapat peningkatan jarak tempuh kendaraan, efisiensi kendaraan, daya, dan torsi. Hasil pengujian daya juga menunjukkan peningkatan setelah dilakukan <em>remapping </em>yaitu dengan selisih daya terbesar mencapai 10.21 kW. Selain itu hasil pengujian torsi menunjukkan terdapat peningkatan torsi yaitu rata-rata sebesar 5.7 N.m.</p>

Missing Tooth

Automotive industry is migrating to electronic based control which has promoted the evaluation and enhancement of engine control performance using electronic components in the research field. Modern engines are controlled by Engine Control Unit (ECU) where not only functions and control systems are in placed, but also the fail-safe mechanisms must be integrated in the ECU to ensure user safety when an error occurred. This work focuses on developing a reliable crankshaft function in an ECU using field-programmable gate array (FPGA). ABa test is carried out and the number of occurrences at unintended location are being monitored in the system to detect the random missing tooth. The reliability of the function is tested by evaluating response of the crankshaft function in an ECU when an unexpected missing tooth occurs during its operation. The developed system is able to detect the random missing tooth on a crank trigger wheel at an accuracy of 100% when the wheel is on a run at a constant wheel rotational speed. It also flags error message for further processing in other functional units of the ECU as a safe-fail mechanism for the system. Implementation of the random missing tooth detection in the crankshaft function is shown to work in the system which is developed using Verilog code

The author’s present concerns about the study opportunities offered by the control unit (which allow experimental programming) related to viewing, adjusting and recording certain engine operating parameters. For a dedicated power supply solution (in which we find an own admission variant of route) functional enhancements the related to the settings type of injection, number of injections, injection time and air mixture – fuel, are proposed. Performance evaluation, approached in a sequence type identification system was done using a testing methodology specific to the chassis dynamometer bench to highlight the targeted optimizations.
