Engine Oil Pan And Functions

Engine anoint move And FunctionsThis report exclusivelyow for analyze the engine embrocate genus Pan as one of metallic function in car application. The analysis testament overlie the role of the component, the hearty for the component and the properties of the material. We will sweep the touch of how the properties are achieved. We will excessively analyzing the alternative material equal for the specific component, canvass and contrast with the alternative material.IntroductionEngine crude fossil vegetable oil scrap is a simple self-propelling component with a very simple function. However, it is very vital for youre the engine part to operate properly. By understanding the function, the specific requirement and the material for an oil pan, it would help us to understand more on material selection for specific automotive applications.Engine Oil Pan and FunctionsFor engine to work at its best, it mustiness be running at a specific operate temperature. This te mperature preempt only be maintained with the aid of engine oil that acts as a coolant. Subsequently, it needs a component to store the oil and constantly re employ it. That is the main function of the engine oil pan. Besides a storage component, oil pan will also collect more or less of the residue picks by engine oil while passing finished the engine. Oil pan also served as a bottom cover of engines.Component Condition and RequirementIn relative to the oil pan application, certain condition and requirement of the material should be meet. First, the material for the component should have a good corrosion unsusceptibility. It is to ensure that the oil in the sump will not contaminated. Even though the function of the oil pan is not for cooling, but the good thermal conductivity airplane propeller will give an advantage for the application. Furthermore, it has to have a good ductility to prevent crack or damage due to stone impact. scurvy density in material will be a enormou s advantage for the component, as it will reduce the free metric weight unit. Above all, the most main(prenominal) criteria for the component are the energy to sustain the operating temperature of the engine. However, the engine operating temperature is considered woeful for all kind of metallic material to stand firm.Materials and Properties for Oil Pan applicationIn this paper, we will analyze the properties of throw away atomic number 13 misdirect as a material for the oil pan. aluminium demoralize (2.7 g/cm) is characterized as a nonferrous alloy, which relatively low density material compare to stain (7.9 g/cm) (Callister 2007). Beside low in density, it is also comparatively high thermal conductivity and inherent corrosive resistance in some common environment. Furthermore, the ductility of Aluminum alloys is retained at low temperature due to Aluminum has a FCC crystal structure (fig. 1-1). nerve Centered Cubic Crystal Structure. In hard sphere social unit (a), a reduced sphere unit (b) and in aggregate of some(prenominal) atoms.An important characteristic of this material is the specific strength, which is determined by the elastic strength to specific gravity ratio (Callister, 2007). Even though aluminum alloy have a tensile strength relatively compare to the higher density material (such as brand), on a weight basis it will able sustain a larger ladle (Callister,2007).In particular to the casting alloys use for productions of oil pan in automotive industry, the die casting process is used. In general the AlSiMg alloys is use for the production of the oil pans.Table 1.1 Composition, Mechanical properties and common application for cast- rage treatable Aluminum alloys(Callister, 2007)Silicon in the range of 5 to 12% by weight is the most important element in aluminum alloying due to ability to amplification the fluidity of the molten metal as well as strengthens the aluminum. Magnesium in the range of 0.3 to 1 % by weight is added to increase strength (Smith, 2004).The silicon content in the component will pose the formation of acicular silicon. It will cause the considerable reduction in the ductility of the component. Therefore the genus Oestrus treatment is necessary for the component, after make up process. It is to obtain the appropriate adequate mechanical properties with respect to rigourousness and ductility. The heat treatment process at an appropriate temperature and for an appropriate duration is carried step to the fore to arise the component with a different roughness. In this study, production of oil pan used the solution heat treatment and followed by soupy aging process, indicate by (T6) in table 1.1. As for the oil pan, in the region of a flange is kept untreated in order to retain high train of hardness and low level of ductility. Thus, the hardness will be 85 to 110 HB and the ductility of 0.5 to 2.5%. While on the base region, it is heat treated appropriately to pee a hardness of 55 to 80 HB and ductility greater than 4%. Hence, the ductility is increased and the hardness is reduced.Properties of Aluminum debauch check the Oil Pan RequirementsAforementioned, we had discussed the condition and requirement of the oil pan application. finished the material analysis of Aluminum alloy, we found that aluminum alloy has a good corrosive resistance. Furthermore, the mechanical property of aluminum alloy as good thermal conductivity would provide a better heat dissipation for the engine oil. Through solution heat treatment process the aluminum oil pan have had a sufficient ductility to sustain stone impact from bottom. With a considerably good hardness the aluminum alloy oil pan would maintain the component shape from deformation due some level of impact.Comparison to other accomplishable materials for oil panOther material commonly used to spring up oil pan is low carbon steel. Oil pans made of steel are produced with a stamp forming process. Physically, in con trast to the aluminum alloy oil pan, the steel oil pan is light in weight. It is because it was produce with a thin steel sheet compare to a thicker cast aluminum alloy oil pan.Based on properties of the material, steel oil pan has a higher ductility but less hardness compare to aluminum oil pan that has high hardness and low ductility. Advantage in having high ductility material is the ability to withstand impact without crack or damage. The comparison of those material (Table 1.2) shows the difference in elasticity, which the modulus of elasticity determined the resistance to elastic deformation. The greater the modulus (Steel alloy) the stiffer the material will be.However, with that property the shape of the component will easily deformed. In case of oil pan application, it might damage other component inwardly the pan such as oil strainer. Other advantage of the aluminum oil pan in contrast to steel oil pan is the ability to acts as a noise shield, especially on diesel motor e ngine. In term of heat dissipation, aluminum oil pan will have advantage in dissipating more head compare to steel oil pan.Table 1.2 Room temperature Elastic, Shear Modulus and Poissons Ratio for Aluminum Alloy and Steel Alloy.AluminumAluminum offers many advantages over other materials. any(prenominal) of these include Light weight (2/3 the weight of steel) Machinability uplifted strength-to-weight ratio Non-oxidizing when exposed to air Excellent heat dissipation elevated electrical conductivity Can be cast by all common casting methods Heat treatable for higher strength and hardnessWillian D.
