Finite Element Analysis (FEA) has been used by engineers as a design tool in new product development since the early 1990's. Until recently, most FEA applications have been limited to static analysis due to the cost and complexity of advanced types of analyses. Progress in the commercial FEA software and in computing hardware has now made it practical to use advanced types as an everyday design tool of design engineers. In addition, competitive pressures and quality requirements demand a more in-depth understanding of product behavior under real life loading conditions.

The release of the “Regulation Nr.168/2013”, for the approval and market surveillance of two- or three-wheel motorcycles and quadricycles, of the European Union started a new challenge for the motorcycle industry. One goal of the European Union is to achieve emission parity between passenger cars (Euro 6) and motorcycles (Euro 5) in 2020. The hybridization of motorcycle powertrains is one way to achieve these strict legislation limits. In the automotive sector hybridization is well investigated and has already shown improvements of fuel consumption, efficiency and emission behavior. Equally, motorcycle applications have a high potential to improve efficiency and to meet customer needs as fun to drive as well. Within the development phase the selection of a useful hybridization-level is a very essential part. CAx methods and numerical simulation methods are useful tools during the research and development phase of motorcycles.

This paper describes the method used for heat transfer measurement and prediction on the LiquidPiston XMv3 small rotary engine at its current state of development. A 1D engine model (GT-POWER) and a 3D CFD model (CONVERGE), were coupled together with the objective of quantifying the engine heat transfer losses inside the combustion chamber. Experimental data was used to validate and calibrate the 1D engine model. Parameters used in calibration include heat transfer constants, and equivalent critical orifice for “atmospheric” and “inter-chamber” leak areas. These parameters were calibrated to match experimental motoring traces, and then lumped in with heat release parameters while fitting firing traces. The GT-Power model results were used as boundary conditions for the CFD modelling. A detailed chemistry combustion model (SAGE) was used to better calculate flame front propagation and flame quenching at the engine walls, relevant for a predictive heat transfer modelling.

The performance of an internal combustion engine is significantly affected by its valve train system design. As frictional losses are present at its various interfaces, it consumes considerable amount of energy to overcome these losses. These losses can be determined through simulation models and/or experimental testing. However, the simulations models are prone to error due to definition of boundary conditions and assumptions. Hence experimental determination of frictional losses in valve train system becomes very critical. In general, the valve train friction is estimated using motoring test rigs, where the test specimen is driven by an electric motor. However, in this case the actual dynamics of the engine and combustion related events will not get captured. Also, the lubrication and engine oil temperatures cannot be exactly simulated in a motored friction test bed. This necessitates measurement of dynamic valve train frictional torque in actual engine running condition.

In recent years, the need is growing for a fuel efficiency enhancement of motorcycles equipped with Continuously Variable Transmissions (CVT), of which the vehicle sales volume is rapidly increasing in developing countries. To develop a vehicle with excellent fuel efficiency, a precise estimation of fuel economy is required at the beginning stage of a vehicle development. One of the indices that are used for evaluation of fuel economy of a vehicle is fuel economy to a predetermined test mode of driving (mode fuel consumption). One of the parameters that plays an important role for the mode fuel consumption calculations is pulley ratio of CVT. In rubber belt CVTs for motorcycles, their pulley ratio varies at every moment depending on the balance between the traveling resistance and thrust force applied to the sidewall of the belt. The state of this pulley ratio variation differs among vehicles and/or among CVT specifications.

The worldwide increasing energy consumption, the decreasing energy resources and the continuous restriction of emission legislation cause a rethinking in the development of internal combustion engines and fuels. Alternative renewable fuels, so called bio-fuels, have the potential to counteract these problems. This study concentrates on the usage of alcohol fuels like Ethanol, Methanol and Butanol in non-automotive high power engines, handheld power tools and garden equipment with the focus on mixture formation and cold start capability. Although bio-fuels have been investigated intensely for the use in automotive applications, the different propulsion systems and operation scenarios of non-automotive applications raise the need for specific research. Therefore, a zero dimensional vaporization model was set up to illustrate the connections between physical properties and mixture formation.

Vehicle dynamics control (VDC) for motorcycles had a fast growth during the last 10 years. The available technologies comprise curve-safe ABS and traction control (TC) systems, anti-wheelie control right up to comprehensive motorcycle stability systems including even more control functions. VDC systems rely on real-time information about the current motorcycle dynamic state. Thus motorcycles are equipped with additional sensor units, namely MEMS inertial measurement devices, capable of gathering accelerations and angular rates. Utilizing model-based estimation theory enables the determination of the necessary information about the in-plane and out-of-plane motion, e.g. the motorcycle lean angle. The consumer market MEMS accelerometers and gyroscopes features include low-cost and small footprint, however there are considerable sensor errors to bear with, e.g. noise and bias.

The internal combustion engine is still the most important propulsion system for the individual mobility. Especially for the application of motorcycles and recreational vehicles is the extra ordinary high power density crucial. Today, these engines are mainly 4-stroke natural aspirated MPFI engines. The main difference to the automotive sector is the abandonment of all cost intensive technologies, like variable valve timing, intake air charging or gasoline direct injection. The need for further investigations and implementation of new technologies is given due to the very high share of total road transport emissions of motorcycles and the introduction of the emission limits of EURO5 in 2020. One possibility to reach the future emission limits is the downsizing strategy. For this the potential for emission and fuel consumption reduction is well known.

In the development of motocrosser, the parts which compose the vehicle body especially in the frame receive the heavy loads when it lands on the ground, and high stress generate. Therefore, some problems such as deformation, crack emanating, brocken damage, etc occur occasionally. It took times and costs to take measures for these problems. To solve these problems and to reduce the development term and costs, we developed the method of Jump Landing Simulation. This Jump Landing Simulation enables to measure the vehicle position, which is moving momentarily, easily with high accuracy by introducing "Image Position Measureing Method.". Also, it succeeded to predict the occuring stress with high accuracy.

In two wheelers the front suspension system is mounted on chassis by two steering bearings which are lubricated ball type angular contact bearings with significant radial force components. These bearings are designed to withstand maximum vehicle loads for target durability. Maximum load carrying capacity depends on the number and size of the balls, bearing size and material. For target durability with designed load carrying capacity, the ball contact pressure, bearing preload plays a major role as compared to other design parameters. Geometry parameters and maximum load defines contact pressure for given bearing design. But in two wheelers due to nature of usage and road conditions, the peak loads are dynamic and geometry based design calculations may not yield the most optimal bearing design. In this work the bearing ball race profile design is optimized by using dynamic bearing contact profiles by using nonlinear Finite Element Analysis.

In order to reduce fuel consumption of the HONDA Energy Saving Race car, by analyzing the driving characteristics, the road condition of track and racing rules, a fuel consumption model of racing car was developed based on automobile kinematics theory. The model was applied to study the eco-driving scheme which was mainly focused on optimizing design of throttle opening and the speed range of acceleration and deceleration based on the racing track condition. Several eco-driving schemes ware proposed, and it is gotten the optimum results which is the engine throttle opening is controlled at 60% to 80%, and the vehicle speed is remained in 5 to 65km/h when acceleration and deceleration. In addition, the racing car should coast in neutral fully within the allowable running time by the racing rules. The eco-driving scheme was described in driving cycle and input into the vehicle fuel consumption simulation model developed, and calculated the average fuel consumption.
