What is the purpose of spark advance mechanism?

Purpose of Spark Advance Mechanism:  The purpose of Spark Advance mechanism is to assure that under every condition of engine operation ignition takes place at the most favorable instant in time that is most favorable from the stand point of engine power, fuel economy, exhaust dilution.  Fuel System: In a fuel system contains gasoline which is stored in a fuel tank. This fuel   (Gasoline) supply to the carburetor by using pump.   A carburetor which mixes the gasoline with air and fuel lines connecting the area.  Fuel Pump: There are two types of fuel pump a.       Mechanical fuel pump and b.       Electric fuel pump

What do you mean by Hydraulics and Hydraulic pressure ?

It is simplest sense hydraulics has to do with certain characteristics of liquids such as water and oil. People query   so far as the automotive chassis is concerned is related to the effects of pressure applied to a liquid. It is called Hydraulic pressure. Hydraulic pressure used in the b raking system in shock absorbers and in power steering systems. It is also used in automotive transmission system such as control circuits, fluid coupling, and torque converter, in engine it is more used in water pump, oil pump, hydraulic valve filters, fuel pump and others.  It has been seen that increasing the pressure on a gas will compress the gas into a smaller volume. When pressure increase in a liquid its volume do not reduce. Its volume stay at the same even through the pressure on it is greatly increased. It is incompressible because a liquid can not be compressed into a smaller volume. The molecules of the liquid are rather close together as opposed to a gas in which
