an internal surface of a cylinder bore by reciprocating of a piston, securing the formation of an oil film by an efficient groove formation, by working an area including a groove formed by laser working by injecting grinding liquid in which abrasive grain and coolant are mixed to the area.KAT...
A combustion chamber structure for an internal combustion engine having a hemispherical combustion chamber (6) defined by an inner surface of a cylinder head (4) and a crown of a piston (5), and an electrode (12a) of a spark plug (12) fitted into the cylinder head (4) caused to face...
A cylinder crankcase (1), formed with cylinder bores (3), is monolithically molded from hard material consisting of low-eutectic aluminum alloy added with silicon particles. The inner surface of each cylinder bore is scored using a multi-stage spiral honing process. Each piston, arranged in each...
. Another theoretical study has revealed that EBGvariation in the presence of strain depended on the type and the range of the strain (Jodlowski, 2017). Furthermore, a mechanical strain can be induced through hydrostatic pressure, using piston and cylinder arrangement, convex (tensile strain), ...
The models were full constrained on the bottom and lateral surface of the cylinder of acrylic resin and one 30° off-axis load (300N) was applied on the lingual side of the crown (close to the incisal edge) in order to evaluate the stress distribution (svM) within the implant-abutment ...
PURPOSE:To speed up the combustion velocity by making squish area corresponding to 30-50% of the inner wall area of cylinder in a combustion chamber in which turning flow is produced by squish flow between the bulging portion of piston and the flat portion of cylinder. CONSTITUTION:Squash flow...
For the running surface of the cylinder bore, provision must be made for wear and scuff resistance through use of inserts (often gray iron) or coating processes (McCune 1995). Particularly wear resisting grades of aluminum, such as AA-390 (Jorstad 1983) permit direct action of the piston ...
In a cylinder liner for use in an internal combustion engine, especially for a large diesel engine, and cast from perlitic cast iron with spheroidal graphite as the basic alloy, the microstructure of the cast iron also comprises clearly delimited cementite/steadite proportions, which are uniformly...
the inner surface (4), guaranteeing positive effects on the increase of hydrodynamic lift and on the reduction of the friction pressures on the inner surface (4) of the cylinder sleeve (1) with respect to its sliding parts, with consequent reduction in the consumption of fuel of the engine....
PURPOSE:To thin the wall thickness of a sleeve and enhance its rigidity by winding a high tension wire around the outer periphery of a cylindrical cast with a fixed fastening force, to constitute a cylinder sleeve. CONSTITUTION:A cylinder sleeve 2 is constituted by winding a high tension wire...
