Therefore, dynamic properties of motorcycles should be evaluated not merely dealing with a vehicle but considering with a man-machine system.
In the studies of a simulation for vehicle dynamics, various types of rider models have been proposed and it has already been reported that rider motions have a significant influence on the dynamic properties.
However, the mechanism of the interaction between a rider and a vehicle has not been clarified yet. To construct the rider model, we first measured the vibrational characteristics of a human body using a vibration test bench. Technical Paper The concept of a loop scavenged two-stroke engine, controlling the intake and exhaust port by the moving piston, is a proven way to realize a simple and cheap combustion engine.
But without any additional control elements for the gas exchange this concept reaches quickly its limits for current emission regulations.
The Effects of the Invention of the Automobile The invention of the automobile has brought more positive and negative effects than any other invention throughout the history of transportation. As the most widely accepted method of transportation, cars have .

Amazingly, some of this paper even has ink marks on it, proving that ink was invented much earlier than historians had supposed. Writing Materials Before Paper Of course, people in various places around the world were writing long before the invention of paper.
In order to fulfil more stringent emission and fuel consumption limits with a two-stroke engine, one of the most important measures is to avoid scavenging losses of fuel and oil. Therefore using internal mixture preparation systems in combination with different concepts to control the gas exchange process, the two-stroke engine could become a choice for automotive applications, especially as a Range Extender in a Plugin Hybrid Electric Vehicle PHEV.
Technical Paper In light of a more stringent emission legislation and in anticipation of possible future measures to further reduce the real environmental impact of motorcycles, it is necessary to develop engine concepts which are efficient and low on emissions in a wide range of operating points.
This poses an important challenge on the development of high performance motorcycles engines as their focus on full load behaviour conflicts sharply with the emission and efficiency demands of the remaining engine load map.
The focus of this paper is to evaluate the potential of a port fuel injection PFI concept consisting of one individual fuel injector for each intake valve to solve this trade-off.
Previous research shows a positive effect of such a setup on mixture formation due to better targeting and atomization, reducing HC emissions and cyclic variations. Technical Paper In a variety of applications two-stroke engines asserts their usage as a propulsion unit, for examples in off-road vehicles, scooters, hand-held power tools and others.
The outstanding power to weight ratio is the key advantage for two-stroke engines Furthermore two-stroke engines convince with high durability and low maintenance demand.
However, an increasing environmental awareness, the protection of health and the shortage of fossil resources are the driving factors to further enhance the internal combustion process of two stroke engines.
The reduction of emissions and fuel consumption with a constant power level is focused. Developments deal with the optimization of the combustion process itself or the enhancement of the exhaust gas aftertreatment. Especially in very small two-stroke engines an exhaust gas aftertreatment system is rarely applied, due to disadvantages regarding component temperatures and product costs.
Technical Paper Legislation bodies are increasingly pushing vehicles manufacturers all over the world towards the reduction of emissions and fuel consumption of new developed vehicles. These strict requirements applied to motorbikes manufacturers present them with a big challenge, since the efficiency improvement must be achieved without affecting the performance, in terms of torque and power first, and throttle response and drivability, which are significantly important to a motorbike owner.
The reduction of engine displacement together with the adoption of turbocharging allows shifting the engine operating points in an area of higher efficiency with obvious advantages in terms of fuel consumption.
Technical Paper This study investigated the influence of EGR and spark advance on knocking under high compression ratio, ultra-lean mixture and supercharged condition using premium gasoline as a test fuel.
A high-compression ratio, supercharged single cylinder engine was used in this experiment. As a result, the period from ignition to autoignition was prolonged.
In addition, knock intensity was drastically reduced. In other words, it is inferred that by combining an appropriate amount of EGR and spark advance, high efficiency operation avoiding knocking can be realized.
Technical Paper The small engine is used under the severe environment of a large temperature change. Furthermore, it is required to enhance the thermal fatigue strength since the usage environment become more severe for satisfying emission regulations and the demands for high engine power.
Hypoeutectic aluminum-silicon alloys are usually utilized for the material of the small engine due to their well-balanced properties such as density, castability and mechanical characteristics. In these alloys, the ductility, which strongly affects the thermal fatigue strength, differs depending on the morphology of the eutectic silicon.
Herein, we controlled the morphology of the eutectic silicon by the addition of calcium and investigated castability and the mechanical properties.
The sample with different calcium amount and cooling rate in cast was prepared. From cross-section images, it was revealed that the morphology of the eutectic silicon became fine with increasing the calcium amount and the cooling rate.
Technical Paper Indian Two-Wheeler Industry is the largest in the world with the annual growth rate more than 10 percent year after year. Ever rising fuel demand and global concern on climate change have focused to develop energy efficient and eco-friendly vehicles.
Several techniques such as engine design, efficient transmission and use of better quality of fuels and lubricants are applied world over to improve the efficiency of the vehicles.
Low viscosity engine lubricant is one of the approaches which can be easily applied for better fuel economy.Essay: History of the Automobile. Automobiles are one of the most important and prominent inventions possibly ever created.
