Basic of a Reciprocating pump:  A  reciprocating pump  is a  pump  which uses a backward and forward movement to move a fluid. In a  reciprocating pum p , a piston, plunger, or diaphragm moves backward and forward. A  reciprocating pump  is one in which the liquid follows the movement of a piston during suction and delivery strokes.

Lubricating oil, simply known as lubricant or lube, is a class of oil used to reduce friction, wear and heat between two mechanical components contact each other. Lubricating oil is used for these types of reasons: i. As a cleaning agent ii. As a cooling agent iii. Reduce wear between two mechanical parts iv. Making a sliding seal between cylinder wall and piston wall v. Keep the cylinder head cool There have more advantages. How lubricating oil  works in engine:  Oil is stay in Oil pan. Then oil in pumped and send to oil filter. Then oil is send to main Oil gallery. From their oil is send to camshaft and rocker shaft.

A Limited-slip differential (LSD) is a differential that allows it two output shafts at different speed but limit the maximum distance between two shafts. n an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.

Fuel Pump A  f uel pump  is a frequently (but not always) essential component on a  car  or other  internal combustion engined  device. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank or under high pressure to the  fuel injection  system. Often, carburated engines use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine).  Fuel pressure needs to be within certain specifications for the engine to run correctly. If the fuel pressure is too high, the engine will run rough and rich, not combustion all of the fuel being pumped making the engine inefficient and a pollutant. If the pressure is too low, the engine may ru

Any liquid-cooled  car  engine has a small device called the  thermostat  that sits between the engine and the radiator. ... When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the  thermostat  opens. For maintaining engine temperature thermostat is essential for every car. It maintain the engine temperature.
