Alternator (120 A)

2) Charging

The alternator uses a new regulator which has three diodes. It consists of the delta stator, rectifier bridge,

slip ring and brush.

Charging time according to vehicle conditions and environment

▶

Specification: Charging a fully depleted high-

capacity battery takes twice or more as long as

charging a fully depleted battery for small

vehicles.

Temperature: The lower the temperature is, the

longer the time taken to charge the battery.

When connecting the battery charger to the cold

battery, the amount of current the battery can

accept initially is very small. As the battery gets

warmer, it can accept more current.

Charging capacity: Charging a battery with a low-capacity charger takes longer time than charging with

a high-capacity charger.

Charging status: Charging a fully depleted battery takes twice or more as long as charging a half-

depleted battery. Since the electrolyte in a fully depleted battery consists of nearly pure water and

conductor, only a very small amount of current can be accepted by the battery initially. The charging

current increases as the amount of acids in the electrolyte is increased by the charging current.

1. OVERVIEW

The pre-heating system for D20DTR engine has the glow plug to the cylinder head (combustion

chamber), and improves the cold start performance and reduces the emission level.

The pre-heating resistor (air heater) is used to heat the intake air.

This enables the diesel fuel to be ignited in low temperature condition.

The ECU receives the information such as, engine rpm, coolant temperature, engine torque, etc.,

through CAN communication during pre-heating process; and the pre-heating control unit controls the

pre-heating, heating during cranking and post-heating by the PWM control.
