Parts of engine -4

HELLO FRIENDS, Previous article we have discuss parts of engine crankcase, cylinder liner and piston introduction. In this article we have discuss material  of  piston and piston  clearance. So…..lets start,😊 Material  for piston : The material used for piston is mainly aluminium alloy. Aluminium piston can be either cast or forged. Cast iron is also used for piston. Yearly  cast iron was almost universal  material for piston because it's excellent  wearing qualities, co-efficient of expansion and general  suitability in manufacture. Due to reduce of weight of metal is necessary, light metal is lost. Aluminium is inferior to cast iron in strength and wearing qualities, and it's greater  co-efficient of expansion greater clearance in the cylinder to avoid the risk  of seizures. The thermal heat conductivity of aluminium  is about three times that of cast iron and this combined  with greater thickness necessary for strength, enable an aluminium alloy piston to run at

HELLO FRIENDS, Previous article we have discuss parts of cylinder block, cylinder head and this article we have discuss crankcase and cylinder liner and piston introduction. So…..lets start,😊 3. Crankcase: Crankcase is attached to the bottom face of the cylinder block. Crankcase is base on the engine. It is supported the crankshaft and camshaft in suitable bearings and provided the arm for supporting the engine on the frame. The oil pan and the lower part of cylinder block together are called the crankcase. Sometimes you are thinking about oil pan, so I can explain this oil pan is bottom half of the crankcase is called oil pan show in figure. it is bolted or screwed to the lower flange of the main casting are usually made of pressed  steel and aluminum. In the crankcase cylinder block and upper half of the crankcase usually are cast as single integral unit. This casting is usually made of a ferrous alloy or semi-steel provide to stronger and hard

Hello friends, Previous article we have discussed in cylinder block. In cylinder block are the round mirror cylinder surface by accurate grinding and honing process and this article we have discussed in cylinder head. so...let's start 🤔 2. Cylinder head:           The top of the cylinder is covered by separate cast piece know as the cylinder. the cylinder head is bolted to the top of the cylinder block. it contains combination chamber. In cylinder head are mounted on spark plug and sometimes valves are mounted in it and passages for flow of cooling water. The cylinder head is usually made by gray cast iron or aluminium alloy. Aluminium has the advantage of lightness in weight and high heat conductivity. It is cast separately from the cylinder block, it may be removed for cleaning carbon and grinding valve. A flat piece of gaskets is placed between the cylinder head and cylinder block. Racing car engine, a separate head is not use. But single piece of cylinder block and hea

Hello friends, Previous article we have discussed how many types of Engine cylinder.... In this article we have discussed step by step.....so let's start.. 1. Cylinder block :                Cylinder block, cylinder head and crankcase these three parts are the foundation of body of automobile engine. Cylinder blocks and crankcase are single form of casting, which gives a rigid structure of casting. In cylinder block are made of some parts name are hear is water passages,dry liner, bearing of crankcase, ribs...etc. Ribs are cast in the crankcase to give in extra strength and support and some cases, the crank shaft bearing. In a cylinder block are three parts : 1. The cylinder in which the pistons slide up and down. 2. The port or opening for valve. 3. The passages for the flow cooling water. The cylinder block is usually made by gray cast iron and sometimes with additional nickel and chromium. Some block are cast iron from aluminium, in which cast iron of steel
