Navigation devices for cars are ubiquitous and become increasingly popular for motorcyclists as well. The motorcycle navigation devices were optimized for motorcyclists regarding their range of functions, but the interaction with these navigation devices are not optimized for motorcyclists. In this thesis, we explore vibrotactile feedback for motorcycle navigation. We evaluated the vibration th...

This study aimed to examine the practices and perceptions of motorcycle taxi drivers concerning the use of personal protective equipment (PPE), based on field research and an exploratory and descriptive qualitative approach. Thirty motorcycle taxi drivers from Jequié, Bahia State, Brazil, were interviewed. Data collection used a semi-structured interview and questionnaire. Data were analyzed us...

This paper presents a motorcycle direct dynamic formulation by the Jourdain’s principle approach. This vehicle is considered as an assembly of six rigid bodies and the resulting equation of motion allows to simulate 11 Degrees of Freedom (DoF). The vehicle geometry is described and a step by step procedure is introduced to evaluate the kinematics and the generalized efforts of the considered ve...

In turbocharged engines with wastegate the exhaust pressure can change rapidly. A method to estimate the exhaust manifold pressure is presented for diagnosis of wastegate and turbocharger on spark-ignited engines. It does not require any extra sensors in the exhaust system after the calibration. A non-linear model is developed of the exhaust pressure. Estimates of the exhaust manifold pressure ...

Gasoline engine exhaust has been considered as a major source of air pollution in China. Due to lower cyto- and geno-toxicity effects of methanol engine exhaust, methanol is regarded as a potential substitute for gasoline. We have previously compared cyto- and geno-toxicities of gasoline engine exhaust with that of methanol engine exhaust in A549 cells (Zhang et al., 2007).To characterize the i...

conclusions the result of this study did not find an independent association between adhd and helmet use. results univariable analysis showed the mean of the age variable was significantly higher in the helmeted group, 26.94 ± 7.72 vs. 23.08 ± 7.7.32, (p < 0.001). the majority of the non-helmeted group was single (p < 0.001). subjects with secondary educational level were more often in the helm...

Eco idle system is a to reduce exhaust emission, fuel consumption and number of engines spend during idling on the road by shutting off automatically. The purpose this project develop simulation an eco-idle install it motorcycle which will turn motor after several seconds in mode. In project, there are few parts that have been used kit for motorcycles. circuit coding were created Integrated Dev...

The effect of antilock braking systems (ABS) on motorcyclist fatal crash risk in 2005-06 was studied by comparing fatal crash rates per registrations of motorcycles with and without ABS. Study motorcycles included those for which ABS was optional equipment and could be identified as present by the model name. Fatal motorcycle crashes per 10,000 registered vehicle years were 38 percent lower for...
