Event
Mixed modes with both flame propagation and slow auto ignition. Distinct from SI knock: autoignition is desired and will not ruin the engine. Papers describing experiments and test data, simulation results focused on applications, fuel/additive effects, and SACI mode change are invited and will be placed in appropriate sub-sessions. Papers with an emphasis on the modeling aspects of combustion are encouraged to be submitted into PFL 110 or PFL120 modeling sessions.

Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%.

Cylinder liners exert a major influence on engine performance, reliability, durability and maintenance. Various combinations of non-metallic reinforcements and coatings have been used to improve the tribological performance of sleeves or surfaces used in compressors and internal combustion engines in four stroke, two stroke and rotary configurations. In this paper we report the use of a hybrid composite containing silicon carbide and graphite in an aluminum alloy matrix to improve the performance of various small engines and compressors. Material properties of the base material, as well as comparative dynamometer testing, are presented.

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

Injection molding is a common molding method for plastic parts and is widely applied to outer parts of motorcycles. To make it stiff enough to hold a large load, glass fibers are usually mixed in it. However, when a plastic part contains glass fibers, the appearance of the outer surface becomes deteriorated after molding. It is because the glass fibers come out of the surfaces. Therefore, the surfaces of these parts are painted to conceal the exposed fibers. Moreover, in the case of glass fiber reinforced plastic made from polypropylene (PP-GF), glass fibers easily come out of the surface and painting is not easily applied. Accordingly, PP-GF hardly satisfies the requirements for outer appearances. In this development, a method that fulfills the appearance requirement and is applicable to mass production was established using rapid heat and cool molding (H&C molding) while eliminating painting process for cost reduction.

On a worldwide scale, turbocharged four-cylinder engines are the most used ones in automotive industries. Three-cylinder engine is a technical alternative because of its higher thermodynamic potential that is due to higher cylinder displacement. Following this trend, the interest in two-cylinder engines is growing. These do have special demands concerning uniformity and dynamics of oscillating masses and firing order, but also very different conditions for the turbocharger. With two-cylinder engines, the pulsating influence grows and changes the operation of the turbine. In this paper different boosting technologies are compared in small engine applications. Besides of turbochargers the potentials and limits of superchargers and electric chargers as well as their combinations are compared. These technologies show dissimilarities concerning power supply, operation range and efficiency, and these effects have different meaning in small engines.

With the remarkable rise of gas price and the global air pollution, measures to improve fuel efficiency and reduce emission have become the urgent need in the motorcycle industry following automobile. For the improvement of the engine thermal efficiency that is one of those problems, there is a well-known fact that various research and development are continued from the past. We recognize that the coexistence of the high mobility and fuel efficiency performance of the Community-Based small motorcycles are demanded in the developed country not only developing countries. And we recognize that the coexistence of driveability and emission control of recreation and sports motorcycles is demanded. However, in the development of the engines for small motorcycles, due to differences in engine speed range, emission control, cost, infrastructure, we need some different approaches from the automobile engines which are full of advanced technologies.
