when you turn the key on a 1997 Ford Escort then electricity flows to the permanent magnet starter motor electrical terminals and forms an electromagnetic field in the permanent magnet starter motor six electromagnetic poles and then the six electromagnetic poles electromagnetize the starter armature and spin or rotate the starter armature and spin the starter armature and spin the cogged starter flywheel engagement ring and electricity also flows to the starter solenoid electrical terminals and pushes the starter solenoid plunger forward and pushes the starter solenoid plunger return spring forward and pushes the starter solenoid plunger lever forward and the starter solenoid plunger pulls the spinning starter armature and spinning starter flywheel engagement ring forward and the starter solenoid plunger pulls the spinning starter armature and spinning starter flywheel engagement ring toward the engine flywheel ring gear and the spinning starter armature and spinning starter flywheel engagement ring then spins the engine flywheel ring gear spins the engine flywheel spins the engine crankshaft spins the five crankshaft main journal surfaces around the ten crankshaft main bearing inserts and around the five crankshaft main caps spins the four crankshaft counterweights spins the four crankshaft connecting rod journal surfaces around the eight crankshaft connecting rod bearing inserts spins the four connecting rod caps spins the four connecting rod big ends and pushes up and down or reciprocates the four connecting rod small ends reciprocates the four piston wrist pins or four piston pins reciprocates the eight piston skirts on the side of the four pistons reciprocates the four piston crowns or top of pistons reciprocates the four pistons and piston ring assemblies up and down in the cylinder bores or cylinder walls at the same time the spinning crankshaft spins the crankshaft driven oil pump inner and outer gears spins the crankshaft timing belt sprocket spins the cogged timing belt spins the water pump sprocket and water pump impeller spins the timing belt tensioner spins the timing belt camshaft sprocket in the cylinder head spins the camshaft journal surfaces around the camshaft bearing inserts and around the camshaft caps in the cylinder head spins the eccentric intake and exhaust camshaft lobes pushes up the hydraulic valve lifters or hydraulic valve tappets or hydraulic valve lash adjusters pushes up the back ends of the rocker arm fulcrums which push down the front ends of the rocker arm fulcrums pushes down the valve return springs pushes down the valve stem tips pushes down the valve stems through the valve guides in the cylinder head pushes down the intake and exhaust valves in the combustion chamber at the bottom of the cylinder head and top of the engine block and pushes down and opens the intake and exhaust valves in the combustion chamber,,,,,, at the same time electricity flows to the in-tank gas tank electric fuel pump electrical connectors and to the electric fuel pump electrical terminals and to the electric fuel pump two electromagnets and then electricity forms an electromagnetic field in the two electric fuel pump electromagnets and the two electric fuel pump electromagnets electromagnetize the electric fuel pump armature spin the electric fuel pump armature spin the electric fuel pump impeller spin the electric fuel pump rotor spin the electric fuel pump turbine or pumping element and the electric fuel pump turbine pumps and pressurizes gasoline to the closed electronic fuel injector disk-shaped electromagnetic valves or disk-shaped electromagnetic needle valves,,,,,,, now to open the electromagnetic disk-shaped injector valves now electricity flows to the plastic green silicon plate multiple pin electrical connectors flows to the plastic green silicon plate white routing lines flows to the plastic green silicon plate power transistors and integrated circuits or ICs which are stamped right on the plastic green silicon plate white routing lines,,,,,, but before it reaches the electromagnetic disk-shaped fuel injectors electricity is first modified and altered by some sensor electrical resistors or sensor variable electrical resistors so the silicon plate electricity is modified or altered by a coolant temperature sensor thermistor by an intake air temperature thermistor or inlet air temperature sensor thermistor by a mass air flow sensor potentiometer by a throttle position sensor potentiometer by an idle speed control solenoid valve potentiometer by a differential pressure feedback EGR sensor potentiometer or differential pressure feedback EGR electronic transducer potentiometer by an EGR vacuum regulator solenoid potentiometer or EGR solenoid valve potentiometer by an evaporative canister purge solenoid potentiometer or EVP canister purge solenoid potentiometer by an air conditioning pressure or AC pressure cycling switch potentiometer,,,, (the upstream exhaust gas oxygen sensor potentiometer and downstream exhaust gas oxygen sensor potentiometer only get in the picture and get activated after the engine starts in the closed loop mode of operation when the engine warms up))))),,,,, so after the silicon plate electricity is modified and altered by the above sensor electrical resistors or sensor variable electrical resistors then the modified electricity reaches the four electronic fuel injector electrical connectors reaches the four electronic fuel injector electrical terminals and forms an electromagnetic field in the four electronic fuel injector electromagnetic coils and the electromagnetic field in the four electronic fuel injector electromagnetic coils then electromagnetizes the four electromagnetic injector disk valve armatures or disk valve plungers pulls open the four electromagnetic disk valve armatures or disk valve plungers pushing up the electromagnetic injector disk valve return springs pulls open the electromagnetic injector disk valves or electromagnetic injector disk-shaped needle valves and now the gasoline that was pressurized from the in-tank electric fuel pump armature impeller rotor turbine that pressurized gasoline now flows out of the opened electromagnetic injector disk-shaped valves and forms a fine spray mist that flows through the opened engine intake valves and into the combustion chamber,,,,,, now to ignite that gasoline mist then electricity flows to the two distributorless ignition coilss electrical connectors flows to the two distributorless ignition coilss electrical terminals and then electricity forms an electromagnetic field in the two distributorless ignition coilss low voltage primary ignition coil windings,,,, also the spinning crankshaft and spinning crankshaft timing belt sprocket spins a crankshaft harmonic balancer or vibration damper spins a toothed crankshaft trigger wheel reluctor with a gap between the toothed trigger wheel reluctor teeth and when the gap in the spinning trigger wheel reluctor teeth when the gap in the trigger wheel reluctor teeth reaches the crankshaft position sensor mounted right above the trigger wheel reluctor then the gap in the trigger wheel reluctor teeth the gap triggers or activates the crankshaft position sensor and triggers or activates the distributorless ignition module silicon plate labelled electronic distributorless ignition system 4 or EDIS 4,,,, the gap in the trigger wheel triggers the crankshaft position sensor and triggers the distributorless ignition module silicon plate to temporarily interrupt the flow of low voltage primary electricity into the distributorless ignition coilss low voltage primary windings and the electromagnetic field that has formed in the two distributorless ignition coilss primary windings now collapses and forms a high voltage secondary current or high voltage secondary electricity into one of the two distributorless ignition coilss secondary windings or high voltage secondary windings and the high voltage secondary ignition current travels from the distributorless ignition coils secondary windings to the ignition coils secondary electrical terminals to the high voltage spark plug cables and spark plug boots and the secondary ignition current jumps the gap of the electrodes of two of the four spark plugs and forms a high voltage electrical arc in two of the four spark plugs one spark plug electrical arc is in the power stroke the other spark plug electrical arc is in the exhaust stroke,,,, and the spark plug electrical arc in the power stroke ignites the gasoline spray mist from the in-tank electric fuel pump armature impeller rotor turbine and from the electromagnetic fuel injector disk-shaped needle valve and the ignited gasoline mist pushes down the piston crown pushes down the piston skirts pushes down the piston rings pushes down the piston wrist pins or piston pins pushes down the connecting rod small ends which spin the connecting rod big ends spin the connecting rod caps spin the connecting rod crankshaft journal surfaces around the connecting rod bearing inserts spin the main crankshaft journal surfaces around the main bearing inserts and around the main caps spin the crankshaft counterweights spin the crankshaft spin the crankshaft flywheel spin the crankshaft driven oil pump inner and outer gears spin the crankshaft timing belt sprocket spin the cogged timing belt spin the water pump sprocket spin the water pump impeller spin the camshaft timing belt sprocket spin the camshaft journal surfaces around the camshaft bearings and camshaft caps spin the eccentric intake and exhaust camshaft lobes push up the hydraulic valve lifters or hydraulic valve tappets or hydraulic valve lash adjusters push up the back ends of the rocker arm fulcrums push down the front ends of the rocker arm fulcrums push down the intake and exhaust valve springs push down the intake and exhaust valve stem tips push down the intake and exhaust valve stems through the valve guides in the cylinder head push down the intake and exhaust valves opening the intake and exhaust valves and the power stroke keeps repeating itself in the four combustion chambers and now all of the above described parts spin and reciprocate on their own without the help of the starter armature and starter flywheel engagement ring and the starter solenoid plunger return spring now pushes the starter solenoid plunger lever back which pushes back the now non-spinning starter armature and starter flywheel engagement ring away from the power stroke spinning flywheel ring gear and flywheel and the starter armature and starter flywheel engagement ring return right between the six permanent magnet starter motor six electromagnetic poles,,,,,, and when you put the 1997 Ford Escort in drive then the spinning crankshaft and spinning flywheel also spin an automatic overdrive transaxle torque converter fluid coupling which spins the automatic overdrive transaxle planetary gears and the automatic overdrive transaxle planetary gears spin the automatic overdrive transaxle differential gears (the automatic transaxle planetary gears and automatic transaxle differential gears are combined in a single unit in front wheel drive cars called the automatic transaxle rather than the separate automatic transmission and separate differential gears in rear wheel drive cars now mostly pickup trucks and SUVs))))),,, so the spinning automatic overdrive transaxle differential gears spin the inner constant velocity joints or inner CV joints spin the right and left constant velocity half-shafts or right and left CV half-shafts spin the outer constant velocity joints or outer CV joints spin the drive front wheels which spin the neutral rear wheels that neither steer nor drive the vehicle (1997 Ford Escort that is)))))),,,,, electricity also flows to an automatic transaxle silicon plate or automatic transaxle module and then is modified or altered by a transaxle range sensor potentiometer or transaxle range switch potentiometer as well as by a vehicle speed sensor potentiometer or VSS vehicle speed sensor potentiometer electronically affecting how the four speeds or four sets of planetary gears are shifting or interacting with each other in what is called the electronically controlled electronic four speed automatic overdrive transaxle,,,, (transmission planetary gears and differential gears combined in a single unit integrated unit called the automatic transaxle rather than the automatic transmission in rear wheel drive cars now mostly pickup trucks and SUVs))))))),,,,,, also the spinning crankshaft and spinning crankshaft timing belt sprocket and spinning crankshaft toothed trigger wheel reluctor and spinning harmonic balancer or vibration damper they also spin a crankshaft pulley and the crankshaft pulley then spins an alternator pulley which spins an internal alternator fan behind the front alternator cover metal rib cage the internal alternator fan spins the alternator rotor spins the alternator rotor two electromagnetic poles around the alternator stator windings and the two spinning alternator rotor electromagnetic poles then form an electromagnetic field that forms an alternating current or ac that flows in variable directions through the alternator stator windings and then the alternating current or ac is rectified through the alternator rectifier plate in the back of the alternator and the alternator diodes in the alternator rectifier plate then convert the alternator alternating current from the stator windings the rectifier plate diodes convert the alternating current into direct current or dc that flows in a single direction rather than variable directions as alternating current does and that spinning alternator pulley and spinning alternator internal fan and spinning alternator rotor electromagnetic poles keep supplying a steady output and steady production of electricity to the in-tank electric fuel pump electrical terminals and electromagnets and also to the fuel injection plastic green silicon plate white routing lines and power transistors and integrated circuits or ICs and also to the sensor electrical resistors or sensor variable electrical resistors of coolant temperature sensor thermistor intake air temperature sensor thermistor or inlet air temperature sensor thermistor mass air flow sensor potentiometer throttle position sensor potentiometer idle speed control solenoid potentiometer differential pressure feedback EGR sensor potentiometer or differential pressure feedback EGR electronic transducer potentiometer EGR vacuum regulator solenoid potentiometer or EGR solenoid valve potentiometer evaporative canister purge solenoid potentiometer or EVP canister purge solenoid potentiometer air conditioning pressure cycling switch potentiometer or AC pressure cycling switch potentiometer upstream exhaust gas oxygen sensor potentiometer and downstream exhaust gas oxygen sensor potentiometers,,,,, also disk-shaped electromagnetic fuel injector electrical terminals and electromagnetic coils,,,, ,,,, also crankshaft position sensor distributorless ignition coils distributorless ignition coilss electrical terminals and distributorless ignition coilss primary or low voltage electromagnetic coil windings for each of the two distributorless ignition coils distributorless ignition module silicon plate,,,, also automatic transaxle silicon plate transaxle range sensor or transaxle range switch as well as vehicle speed sensor or VSS sensor,,,, also electric cooling fan cycling switch and electric cooling fan electrical terminals electromagnets armature impeller rotor and fan blades,,,,, and that concludes the complete description of the components and function of the 1997 Ford Escort and how they interact with each other
