Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

The experimental study was conducted to investigate the effects of different opening ranges of waste gate of a turbocharged medium displacement spark ignition engine on improving work parameters such as exhaust emission, torque characteristics and fuel consumption. The object of the experimental tests was an engine with modified intake and exhaust manifolds. The intake and exhaust manifold modi...

Abstract The structural design of a mechanical temperature-driven shut-off valve used in the water and steam sampling device power plant is designed using Iventor drawing software. A NiTi shape memory alloy with high temperature-sensitivity as driven spring to control opening closing valve. In addition structures common parts valve, calculation parameter-design are also carried out. unimpeded c...

In filling lines equipped with membrane separation devices in the form of filters energy, consumption is only one important working parameters, other being sustainable filter performance terms efficiency. As line typically a valve, intermittent operation an its use. Whereas overall energy filtration process governed by continuous mode, characterised opening/closing contributes most to problems ...

The effects of the valve opening and opening height are very crucial in internal combustion engine. The optimum setup for the opening cam high and timing of camshafts in engines will improve fuel economy and exhaust gas emission. This improvement can be obtained from intake (inlet) valve timing and also from exhaust (outlet) valve timing. The challenging technique is to set up the engine to the...

This paper presents a failure analysis on a failed intake valve in a gasoline engine. During an endurance test, an intake valve was broken and caused some damages on the piston. Material examinations (by a light microscope and also a scanning electron microscope) were conducted on the fracture surface of the intake valve shaft. Results showed that no pores or defects could be observed and the m...
