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. A vehicle fitted with the Load Control Module was tested in city driving cycle (CDC) condition as per ARAI (Automotive Research Association of India) standard and it was found that the electrical loading decreased to about 30% when compared to vehicle with uncontrolled loading.

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. Our studies exceeded the limitations of downsizing the electric motors by mainly using the engine combustion energy instead of the electric energy to go over the first compression top dead center.

J1578_201410
This test procedure provides a standard method for evaluating the side stand retraction performance of a side stand/motorcycle combination. This test procedure applies to any two-wheeled motorcycle without a sidecar, equipped with a side stand, and intended for highway use. (See SAE J213.) This SAE Recommended Practice is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering the use of this document.

These requirements define minimum recommended levels of side stand retraction performance of a new side stand/motorcycle combination when tested according to the procedures of SAE J1578. These requirements apply to any new two-wheeled motorcycle without a sidecar, equipped with a side stand, and intended for highway use. (See SAE J213). This SAE Recommended Practice is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering use of this document.

J1846_201410
This SAE Recommended Practice is intended for use only in characterizing test surfaces used in motorcycle side stand retraction testing (SAE J1578). The equipment and procedure described in this document yields repeatable results in characterizing test surfaces in a way found to be related to retraction performance. The test results obtained with this procedure do not necessarily correlate with measurements obtained with other friction measurement procedures which have been developed for other purposes.

1.1 This SAE Recommended Practice covers the design and application of primary on-board wiring distribution system harnessing for surface vehicles. This document is intended for single phase nominal 120 VAC circuits that provide power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off. The power supply comes from alternative sources such as land-based grid power, DC-AC inverters and auxiliary power generators. The circuits may also provide power to improve vehicle performance through charging batteries or operating cold-weather starting aids. 1.2 This document is not intended to provide guidance for electric or hybrid electric vehicle wiring circuits. Refer to SAE J1673 for high voltage automotive wiring assembly design. 1.3 Engine block heaters are 120 VAC devices that are used on a multitude of vehicle platforms in addition to trucks with sleeper cabs. Generally, the engine block heater circuit is wired independent of hotel loads. SAE J2698 does not apply to independently wired engine block heater circuits.

This procedure measures the resistance to radiant heat flow of insulating materials in sleeve form. The sleeve's effectiveness (S{sub}E) is determined by measuring the difference in surface temperature of a flat black, single- diameter ceramic cylinder with and without the standard diameter sleeve at the specified temperature, position, and distance from the radiant heat source.

This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing. Communication between vehicle manufacturer and the governing authority is essential when starting official manufacturer in-house and official government confirmatory testing that incorporates this practice.
