Abstract:

This journal describes a study on the structural effects of DI diesel engine conventional piston and modified pistons. To enhance the combustion efficiency of the engine conventional piston has been modified as shallow depth piston bowl with swirling grooves on the piston crown. Three different widths (5.5mm, 6.5mm and 7.5mm) and constant depth (00 to 50) swirling grooves added on the shallow depth combustion chambered piston crown. The conventional piston and modified pistons has been modeled in CATIA software and structural analysis done in ANSYS 14. In structural analysis observed that defo

Abstract:

Designing pistons with effective cooling is crucial to preventing piston failure and improving engine service life. A piston design that incorporates the heat-pipe cooling technology may provide a new approach that could improve the thermal-tribological performance of heavy-duty diesel engine pistons. A simplified piston crown with an annular reciprocating heat pipe is constructed to demonstrate this concept. The piston crown is experimentally tested on a specially designed reciprocating apparatus. Experimental data indicate that the annular heat-pipe cooling can greatly assist in reducing the

Abstract:

The top land of a piston normally known as the piston crown is an engine part that is continuously exposed to extreme temperature and pressure during combustion. For a compression ratio level, the compressed natural gas with a direct injection system (CNGDI) typically uses a range of compression ratio between gasoline and diesel engines, producing extremely high temperature and pressure which lead to high thermal stresses. Consequently, the piston crown is exposed to direct combustion due to the vertical movement of the piston, leading to various possible damages of thermal stresses. In contra

Appropriate choice of the radius of curvature and the piston crown thickness provides an image of the full bore.

Abstract:

For hypereutectic Al/Si alloys, one of the advantages of thixoforming in comparison with casting routes is the relatively short processing times at high temperatures and hence limited coarsening of the Si phase. Coarse silicon particles give poor mechanical properties. Here two hypereutectic Al/Si alloys (magneto-hydro-dynamically (MHD) stirred A390 from Pechiney and an extruded A390 alloy from Showa in Japan) have been thixoformed to form pistons. Opening up the die entrance to the full width of the crown made the flow into the die more uniform and helped to reduce the tendency for large pore

With the enormous energy demand and environmental concern the interest on the alternate fuels tothe diesel engines has been increased. Among all the fuels alcohols have received a considerable attentionbecause these are bio-based, renewable and are oxygenated. But due to its properties they require higheroperating temperatures in the combustion chambers. Hence in the present work a ceramic coated insulatedengine is developed by incorporating an air gap between piston skirt and crown for the study of alcoholsperformance and emission characteristics.

Aluminum alloys are widely used to produce automotive components, thanks to their great mechanical properties–to–density ratio. Engine components such as pistons are conventionally produced by casting of Al–Si eutectic alloys (Silumin alloys) such as EN AC 48000. Due to the harsh working conditions and the lower ductility if compared to aluminum–silicon alloys with lower silicon content, pistons made of this alloy are prone to fatigue failures in the skirt region. In order to overcome such limits, the use of a Functionally Graded Material (FGM) in the production of a piston is proposed. The ad

Homogeneous charge compression ignition (HCCI) is an advanced combustion strategy proposed to provide higher efficiency and lower emissions than conventional compression ignition. Nevertheless, the operation of HCCI engines still presents formidable challenges. Preparing homogeneous mixtures and controlling the combustion phase are crucial challenges in the context of engine performance. Piston bowl geometry significantly enhances the process by improving the flow and facilitating air-fuel mixing for combustion. On that note, this study utilised the CFD simulation methods to analyse HCCI combu

A simulation model is developed for the piston ring–cylinder liner lubrication problem in a CO2 refrigeration reciprocating compressor.

The piston ring is assumed to be fully flooded at the leading edge, and both the cavitation case and fully flooded case are considered at the trailing edge. Modified Reynolds boundary condition is employed. The simulation results show that, the minimum oil film thickness h
