The optimisation of engine performance by predictive means can help save cost and reduce environmental pollution. This can be achieved by developing a performance model which depicts the operating conditions of a given engine. Such models can also be used for diagnostic and prognostic purposes. Creating such models requires a method that can cope with the lack of component parameters and some important measurement data. This kind of method is said to be adaptive since it predicts unknown component parameters that match available target measurement data. In this paper an industrial aeroderivative gas turbine has been modelled at design and off-design points using an adaptation approach. At design point, a sensitivity analysis has been used to evaluate the relationships between the available target performance parameters and the unknown component parameters. This ensured the proper selection of parameters for the adaptation process which led to a minimisation of the adaptation error and a comprehensive prediction of the unknown component and available target parameters. At off-design point, the adaptation process predicted component map scaling factors necessary to match available off-design point performance data.

PurposeTitanium (Ti) alloys are in high demand in manufacturing industries all over the world. The property like high strength to weight ratio makes Ti alloys highly recommended for aerospace industries. Ti alloys possess good weldability, and therefore, they were extensively investigated with regard to strength and metallurgical properties of welded joint. This study aims to deal with the analysis of strength and microstructural changes in Ti-6Al-4V (Grade 5) alloy after tungsten inert gas (TIG) welding.Design/methodology/approachTwo pair of Ti alloy plates were welded in two different voltages, i.e. 24 and 28 V, with keeping the current constant, i.e. 80 A It was a random selection of current and voltage values to check the performance of welded material. Both the welded plates were undergone through some mechanical property analysis like impact test, tensile test and hardness test. In addition, the microstructure of the welded joints was also analyzed.FindingsIt was found that hardness and tensile properties gets improved with an increment in voltage, but this effect was reverse for impact toughness. A good corroboration between microstructure and mechanical properties, such as tensile strength, hardness and toughness, was reported in this work. Heat distribution in both the welded plates was simulated through ANSYS software to check the temperature contour in the plates.Originality/valueA good corroboration between microstructure and mechanical properties, such as tensile strength, hardness and toughness, was reported in this study.

The purpose of this study was to investigate the effect of valve mechanisms on the exhaust residual gas (ERG) and effective release energy (ERE) of a motorcycle engine. Here, a simulation model and the estimation a new valve mechanism design is presented. An AVL-Boost simulation model and an experiment system were established. The classical spline approximation method was used to design a new cam profile for various valve lifts. The simulation model was used to estimate the effect of the new valve mechanism designs on engine performance. A new camshaft was produced based on the research data. The results show that the engine obtained a maximum engine brake torque of 21.53 Nm at 7000 rpm, which is an increase of 3.2% compared to the engine using the original valve mechanism. In addition, the residual gas was improved, the maximum engine effective release energy was 0.83 kJ, the maximum engine power was 18.1 kW, representing an improvement of 7.2%, and the air mass flow was improved by 4.97%.

The achievement of electronic-based motorcycle engine or Fuel Injection (FI) has better capability or power compared to conventional system vehicles. This research aims to determine the performance difference of using racing electronic control unit (ECU) compared to standard ECU of an automatic motorcycle. The experiment was carried out on a Honda Vario 125cc motorcycle manufactured in 2013. The research method is experimental research and uses descriptive statistic method. Research findings inform that the maximum torque of the standard ECU is 16.63 Nm at 3500 rpm, and the maximum power is 6.36 KW at 4500 rpm. The racing ECU (Iquteche) has a maximum torque of 22.42 Nm at 2500 rpm, and maximum power of 7.70 kW. The apparent increase in torque is around 36.58 % and in power is around 33.9 %. It can be concluded that the Iquteche ECU provides a more optimized engine performance on an automatic motorcycle.Prestasi mesin sepeda motor berbasis elektronik atau Fuel Injection (FI) memiliki kemampuan atau tenaga yang lebih baik dibandingkan dengan kendaraan sistem konvensional.

This paper uses a commercial CAE software GT-POWER to simulate the V-twin cylinder motorcycle engine exhaust acoustics. Ten different engine exhaust pipes with equal and unequal length and with or without arc connecting tube are designed. The engine performance and tailpipe exhaust noise on nineteen different engine speeds from 1000rpm to 10000rpm in wide-open throttle are studied. It is found that the effect of exhaust pipe configuration on the engine performance appears to be negligible. The tailpipe exhaust flow rate will be reduced and the overall sound level will bring down as the arc tube is connected to the exhaust front pipes. Also, the equal pipe length adapted with arc tube design gives a major function on pressure attenuation which may reduce the noise level significantly. The results may be useful for exhaust pipe design.

Engine health monitoring has been an area of intensive research for many years. Numerous methods have been developed with the goal of determining a faithful picture of the engine condition. On the other hand, the issue of sensor selection allowing an efficient diagnosis has received less attention from the community. The present contribution revisits the problem of sensor selection for engine performance monitoring within the scope of information theory. To this end, a metric that integrates the essential elements of the sensor selection problem is defined from the Fisher information matrix. An example application consisting in a commercial turbofan engine illustrates the enhancement that can be expected from a wise selection of the sensor set.

Through macro inspection, chemical composition analysis, hardness test, tensile performance test, microstructure inspection and scanning electron microscope analysis, the causes of clamp crack on TA equipment in the 500kV AC filter field of the ± 800kV converter station were analyzed. The results show that improper selection of the manufacturing process of the equipment clamps will cause more micro-defects inside it, leading to poor mechanical properties and excessive internal stress, which are the main causes of cracking. Corresponding measures are put forward to improve the manufacturing quality of equipment clamps, which can avoid similar failures from happening again.
