HEATER HAS TO BE SWITCHED OFF FOR TEMPERATURE CONTROL BOLERO USES R134a REFRIGERANT, WHICH IS CFC-FREE HEATING, VENTILATION & COOLING 1. COMPRESSOR - Compressor sucks the refrigerant from evaporator , compresses the same and delivers to condenser. 2. CONDENSOR - Condenser is similar to radiator , where the hot, compressed refrigerant is cooled. 3. CONDENSOR FAN - Condenser fan sucks fresh atmospheric air through the condenser aiding in cooling of the refrigerant inside the condenser. 4. REECEIVER-DRIER (RD BOTTLE) - Receives the compressed and cooled refrigerant and removes any humidity from the refrigerant. 5. EXPANSION VALVE - Receives cooled & compressed refrigerant and expands the refrigerant and passes it in to the evaporator. Expanded refrigerent gases are very cold 6. EVAPORATOR - Evaporator is similar to radiator. The expanded cold refrigerant is passed over warm air from inside the vehicle. HEATING, VENTILATION & COOLING 7. BLOWER - Blower fan sucks warm air from inside the vehicle and passes it over the evaporator which has cold refrigerant on the inner side , thus cooling the vehicle interiors. 8. HEATER - Heater is similar to radiator , where hot coolant from the engine is circulated on the inside. Blower fan passes cold air from the vehicle interior. ELECTRICAL SYSTEM THE VEHICLE ELECTRICAL SYSTEM CAN BE BROADLY CLASSIFIED AS : POWER GENERATION - Generation of electrical power when the engine is running - Alternator STORAGE - Storage of electrical energy for use in the vehicle when the engine is not running - Battery TRANSMISSION & CONTROLS - Transmits & controls the power flow to the consumers - Wiring harness, Fuses, Relays. CONSUMERS - Electrical aggregates which consume electricity for functioning. VEHICLE ELECTRICAL SYSTEM OPERATE ON 12 V DC ELECTRICAL SYSTEM POWER GENERATION - Power generation is done by the Alternator. Alternator is driven by the engine through a belt. Alternator consists of : Generation Unit - Generates AC power Rectifier - Rectifies the AC and converts to DC Regulator - Regulates the alternator output voltage to a maximum of 14.5 Volts VACUUM PUMP ALTERNATOR PULLEY Driven by engine GENERATION RECTIFIER REGULATOR ELECTRICAL SYSTEM STORAGE - The electrical energy generated by the Alternator is stored in a Battery for use when the engine is not running. Battery stores the energy in an electro-chemical form. While starting the vehicle , the starter motor , takes electrical energy from the battery. This drains the battery. As soon as the engine is started, the alternator starts charging the battery . - + AMARON ELECTRICAL SYSTEM TRANSMISSION AND CONTROLS - The electrical energy from alternator or battery is transmitted to the various consumers through wires. A bunch of wires is called wiring harness. Also, the flow of electrical energy is controlled by various controls, namely, Fuses, Relays, Switches etc. ELECTRICAL SYSTEM CONSUMERS - Consumers are electrical aggregates which consume electricity for functioning. Some of the major consumers are : • LIGHTING SYSTEM • WINDSHIELD WIPE/WASH SYSTEM • HEATERS/DEMISTERS • WINDOW OPERATING SYSTEMS • DOOR LOCKING SYSTEM • ENGINE MANAGEMENT SYSTEMS • STARTING SYSTEM • HVAC - BLOWER FAN/CONDENSOR FAN VEHICLE DIMENSIONS OVERALLWIDTH OVERALL HEIGHT ANGLE OF APPROACH OVERALL LENGTH ANGLE OF DEPARTURE WHEEL BASE WHEEL TRACK GROUND CLEARANCE VEHICLE WEIGHTS KERB WEIGHT - The unladen weight of the vehicle - No passengers GVW (Gross Vehicle Weight) - The fully laden weight of the vehicle with passengers/goods. PAYLOAD - The difference between GVW and Kerb weight VEHICLE PARAMETERS GRADEABILITY - The maximum gradient a vehicle can climb, under GVW conditions, in first gear. GRADEABILITY , Deg VEHICLE PARAMETERS MINIMUM TURNING RADIUS - The radius of the circle made by the outermost point in the vehicle, while taking a turn with maximum wheel turning TURNING RADIUS VEHICLE IDENTIFICATION NUMBER 1 2 3 4 5 6 WMI A AN A 7 8 9 10 11 12 13 14 15 16 17 VDS VIS N A A A A/N N A N N N N N DRIVE ENGINE TRANSMISSION YEAR PLANT MONTH VEHICLE SERIAL NO.
