Charging Sytem of an Auto bile Study 1

Description:
The charging system included a battery , an alternator with a built-in regulator , and the charging indicator light and wire.
The Alternator has built in diodes, rectifying AC current to DC current.
Therefore , DC current appears at alternator ,”B” terminal. In addition , the charging voltage of this alternator is regulated by the battery voltage detection system. The main component of the alternator are the rotor, rectifier, capacitor brushes, bearing and V-ribbed belt pulley. The brush holder contains a built in electronic voltage regulator.
On Vehicle Inspection:
CAUTION:

• Check that the battery cables are connected to the correct terminals.
• Disconnect the battery cables when the battery is given a quick charge.
• Never disconnect the battery while the engine is running.

Check the Battery Voltage

1. If 20 minutes have not passed since the engine was stopped , turn the ignition switch On and turn On the electrical system(head lamp, blower motor, rear defogger ect.) for 60 seconds to removed the surface charge.
2. Turn the ignition switch Off and turn Off the electrical system.
3. Measure the battery voltage between the negative (-) and the positive(+) terminals of the battery.

Standard Voltage: 12.5~ 12.9V at 20 degrees Celsius (68 “F) 
= If the voltage is less than specification, charge the battery.

Sensor and Touble Code

Teouble Code:

1) P0341 - Camshaft Positon Sensor Circuit Range/Performance.
2)P0343 - Camshaft Position Sensor Circuit High Input.

Description:
Piston position on combustion chamber is the substantial to define the starting of injection timing. All engine pistons are connected to crankshaft by connecting rod. CPS Crankshaft  Position  Sensor senses the information concerning all piston positions and uses this signal to calculate the injection timing and engine speed. Camshaft position sensor (CMPS) Senses the position of camshaft in reference to the upper dead point of compression cylinder and sends this signal, based on w/c the ECM determines the injection sequence of each cylinder and the fuel injection timing

P0016 crankshaft and camshaft correlation.

The cvvt (continuously variable valve timing) system is installed to the chain sprocket of the intake camshaft. This system controls the intake camshaft to provide the optimal valve timing for every driving condition. The ECM controls the oil control valve (OCV), based on the signal output from the mass air flow, throttle position and engine coolant temperature. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions.
