Neutral-point voltage
(1)A conventional alternator uses six diodes to rectify three-phase AC (Alternating Current) into DC (Direct Current). The output voltages generated at the neutral point is utilized Read more Alternator with Neutral-Point Voltage
2.Rectification
(1)Mechanism of rectification of alternator
Construction
The actual alternator forms rectification circuit called rectifier as shown in figure 1 to rectify three-phase alternating current Read more Principle of the Automotive Alternator
Vehicle is equipped with many electrical devices to drive safely and comfortably. The vehicle requires electricity not only while driving but also while it stops.
Therefore, the vehicle has a battery Read more Function of Automotive charging system
The symptoms relating to strong shocks in the driving system in an A/T vehicle can roughly be separated into two types.
• Only shock is sensed
• Both shock and sound are sensed When both shock and Read more Harsh Engagement of the Driving System in A/T Vehicle
Inspection method (gasoline engines)
Inspect the following when cranking the engine.
(1) Pinch the engine compartment fuel hose with your fi ngers and check whether or
not fuel pressure is applied.
(2) Read more Automotive Troubleshooting Fuel System Inspection
The intake shutter is mounted on the intake manifold. The intake shutter is fully open when the engine is operating. To stop the engine, the VSV operates in accordance with the signals from the ECU, and Read more Outline and Operation of Intake Shutter
The diesel throttle is mounted on the intake manifold. The throttle valve, which operates independently from the accelerator pedal, uses the diesel throttle control motor (step motor) to regulate the throttle Read more Diesel Throttle Outline (1CD-FTV/15B-FTE)
Determining Common-rail Fuel Pressure
A fuel pressure that matches the operating conditions of the engine is calculated according to the actual injection volume that has been determined based on the signals Read more Diesel Engine Fuel Pressure Control

As with the convention EFI-diesel, the basic injection timing of the Read more Determining Injection Timing Reference
1. Engine speed correction control
Symptom:
Increased injection volume due to a rise in the pressure in the pump.
Description of control:
Injection volume reduced according to the engine speed.
