Training / Education Classroom Seminars
Starting with a look at the transmission's primary function -- to couple the engine to the driveline and provide torque ratios between the two -- this updated and expanded seminar covers the latest transmission systems designed to achieve the most efficient engine operation. Current designs, the components and sub-systems used, their functional modes, how they operate, and the inter-relationships will be discussed. A manual transmission display will be used to explain ratios and how they function within the driveline.

The enhancement of efficiency will play a more and more important role in the development of future (small) internal combustion engines. In recent years, the Atkinson (or Extended Expansion) cycle realized over the drive train attracted increasing attention. Several OEMs have been doing investigations on this efficiency-increasing principle in the whole range from small engines up to automotive engines up to now. In prior publications, the authors outlined the remarkable efficiency potentials of an Extended Expansion (EE) cycle. However, for an internal combustion engine, a smooth running performance as well as low vibrations and noise emissions are relevant aspects. This is especially true for an Extended Expansion engine realized over the drive train. Therefore, design measures concerning friction and NVH need to be taken to enable possible series production status. Basically, these measures strongly depend on the reduction of the free mass forces and moments.

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.

Thermoplastic bearing materials are being used in automotive transmission architectures where higher pressures and velocities are driving innovation. The benefits thermoplastics offer are high PV capable materials suitable to reduce NVH, increase design freedom while reducing design space, thermal insulation, reduce coefficient of friction, and improve wear resistance when compared to needle bearings. Expanding on the success in automotive may allow for these types of materials to be evaluated in marine lower units, CVT’s, pumps, and other small engine applications

Indian two wheeler market is one of the largest and highly competitive in the world. Indian scooter segment grows at a pace of around 30% YOY. The stiff competition among OEM’s to increase the market share with fuel efficient and high performance products pushes development and calibration engineers to burn the midnight oil to concoct innovative methods to design technology boosted product. Customer expectations are always high in terms of fuel economy, drivability and NVH. Due to higher level of complexity involved in CVT (Continuously Varying Transmission) engine, it is daunting task to optimize for achieving best of NVH characteristics along with Fuel Economy, drivability and reduced exhaust emission. This paper describes the experiment conducted during the development of 110cc CVT four stroke scooter engine. The development and calibration of this scooter was mainly based on real world usage pattern (RWUP).
