Ok in english of Engine..
Engines have different layouts, depending on the vehicle application. Common arrangements include in-line, vee, flat or rotary.
Cylinder blocks:
Cylinder blockThe cylinder block is the largest part of the engine. Its upper section carries the cylinders and pistons. Normally, the lower section forms the crankcase, and supports the crankshaft.
Cylinder block constructionCylinder blocks made of aluminum are lighter than cast-iron blocks of the same size. They usually have cast-iron liners which provide a hard-wearing surface for pistons and piston rings.
Cylinder sleevesA dry sleeve can be cast or pressed into a new block or used to recondition cylinders. A flanged, dry sleeve has a flange to fit a recess in the block. A wet sleeve has an outer surface directly exposed to coolant.
Grey ironGrey iron is a cast iron that contains carbon in the form of graphite, plus silicon, manganese and phosphorus

Cylinder heads:
Cylinder headThe cylinder head bolts onto the top of the cylinder block where it forms the top of the combustion chamber. It carries the valves and, in many cases, the camshafts.
Cylinder head designCylinder head combustion chambers are designed to help improve the swirl or turbulence of the air-fuel mixture, and prevent fuel droplets settling on the surfaces of the combustion chamber or cylinder walls.
Diesel combustion chambersDirect-injection diesels inject into the combustion chamber formed in the top of the piston. For indirect injection, the combustion chamber is a separate chamber formed in the head.
Intake & exhaust passsagesSmaller intake and exhaust passages and ports allow more torque at low engine speeds. At high speeds, smaller passages restrict airflow. Larger passages produce greater power at high engine speeds.
GasketsGaskets form a seal by being compressed between stationary parts where liquid or gas could pass. Gaskets around a rotating part would quickly wear out. Oil seals are used to seal these parts.
TurbulenceTurbulence refers to the swirling motion of a liquid or a gas.
