PROCESS WORKING ENGINE

Of all the machines there are only two that work process work process work process four-stroke and two-stroke, the following will be discussed one by one
  1. Process There are four engine work done two crankshaft rotations to get the power in four cycles and the cycle consists of the suction, Compression step, step of effort, and last step Discard
    • Step suction the suction step, piston moves from top dead centre (TDC) in which the suction valve opens fuel into the combustion chamber and the valve closed Discard
    • Compression step, the step piston moves up 15 degrees before TDC top dead centre towards the suction valve and the exhaust valve is closed the air and mist in the living fuel burn in the press or in the compressed because there is no space bagar little gap temperature will be higher, we remember the fire or burning occurs because there are three components of air, heat, and the media in this case then there is fuel combustion and explosion.
    • Step effort, in this step the suction valve and the exhaust valve is in a closed state because of the explosion resulting from the step Compression causes the piston kicked off point towards the bottom of the work that led to the crankshaft rotates, turning the crankshaft power is generated, where the end of this step a little exhaust valve begins to open
    • Step waste, is in step piston moves up from bottom dead center to the point of death for which the suction valve is closed and the exhaust valve open to remove the remaining residue is in the combustion chamber
 
2. Work Process meaning two-stroke engine is the engine performs two step in one round    piston crankshaft to produce a power which steps are
    • The first step piston moves from top dead center (TDC) when these will hit the piston rinse the position in the space below the piston, piston ring at some point will go through the hole flushing / exhaust gas will enter through the hole gas income generally will be above the sinkhole and revenue hole would be slightly below, at the time of piston rings through the combustion of landfill gas will exit through this hole, when the piston ring passes through the hole in the intake gas pressure rinse chamber will be depressed into the combustion chamber and piston will push the gas 
    • The second step piston moves up from bottom dead point (BDC) to top dead center (TDC) when the piston is going to suck air mixtures Lubricating oil and fuel, when the piston has passed the pit entry and discharge the piston moves up and to compression at 15 degree of lubricating oil mixture combustion chamber, the air and fuel ignite and cause an explosion was a result of the explosion will be repeated back to the first step and so on
