At the 15th Guangzhou International Automobile Exhibition that opened recently, Jianghuai Automobile announced the official launch of its Refine M4 hybrid model, with the price range of the new car ranging from 129,800 to 149,800 yuan. It is reported that the Refine M4 hybrid version is equipped with a BSG 48V integrated starter and generator, and the official announced that its NEDC working condition can achieve a fuel consumption of 8.4 liters/100 kilometers .
The appearance of the new car follows the design style of the old gasoline version. The front face adopts a hexagonal air inlet grille and three chrome decorative strips. The word “Hybrid” emblazoned on the grille indicates this. this New Car Status. The quad headlight adopts a split design for high and low beam. The low beam lights are equipped with a lens and the lamp unit has an elegant and stable shape. The tail shape features simple and smooth lines, and two thick chrome decorative strips also embellish the tail more delicately.
The JAC Refine M4 has a big advantage in terms of size. The length, width and height of the JAC Refine M4 are 5200mm/1890mm/2010mm respectively, and the wheelbase is 3080mm with the two second-row seats supporting the front. and the independent sliding seats at the rear create a spacious lounge area.
In terms of power, the Refine M4 hybrid version is equipped with a 48 V low hybrid system. It is equipped with a BSG starter-generator integrated machine with a maximum power of 12 kilowatts and with a maximum torque of 55. N·m. It is worth mentioning that it can realize automatic start and stop, kinetic energy recovery, enhanced rotation and other functions to further reduce fuel consumption.
What's the problem when the JAC Ruifeng battery light and brake light are on?
13.5-14.5V. Information from Pacific Automotive Network shows that the power generated by the JAC Refeng S7 generator is between 12.6 and 14.5 V, which is also the safe floating voltage value of the 12 V battery. The JAC Ruifeng S7 is positioned as a mid-size SUV and is also the new model “Flagship” SUV from JAC Motors.

Battery
The light is usually on because the generator is not charging the battery. Check the generator, belt and regulator. are defective. The brake light is on because the brake light switch on the brake pedal is not adjusted correctly (whether the screw is loose) and is always on. The answer may not be accurate depending on the car model, you can try.

If the oil used in Ruifeng S7 is good, it is estimated that the first maintenance of the car in the repair store will cost about 600 yuan.
The contents of Ruifeng s7 maintenance manual include: maintenance time, maintenance cycle and main content.
Pay attention to the maintenance of Ruifeng S7:
1. The fuel filter element and air filter element should be replaced every 10,000 kilometers.
The air filter element should be replaced every year or approximately 20,000 kilometers.
2. At 40,000 kilometers, the entire vehicle's oil needs to be changed.
3. Check the gearbox at each service. Although it is not necessary to change the oil, you should check the gearbox oil level regularly and do not change the original factory oil without authorization.
4. Check the spark plugs every 40,000 kilometers and replace them.every 80,000 kilometers.
Other relevant inspection items:
1. Check if the car's coolant level meets the requirements.
2. Check the brake fluid, brake system and oil leaks.
3. Check if the oil level in the power steering reservoir meets requirements.
4. Check battery and window cleaner levels.
5. Check if the generator and air conditioning system are working properly.
6. Check if the steering is light, flexible and reliable, and if the front wheel swings left or right or derails.
7. Check the working status of the lights and horns, and whether the vehicle's front and rear lights are complete (including headlights, width lights, turn signals, brake lights, reversing lights and fog lights ). ).
8. Check the pressure and wear of the car's tires, and replaceace the position of the tires according to wear.
9. Check the battery status.
10. Check the working condition of the engine, whether it is easy to start, whether the operation is smooth, whether the exhaust gas is normal (meaning the exhaust gas reaches the standard), whether the water the oil temperature and pressure meet the requirements, the speed is stable, and there is no abnormal noise.
11. Check whether the frame and steering gear are flexible, bolts are tight, and all pipe joints and tees should be intact, tightly coupled and airtight.
12. Check whether the relevant parts of the vehicle need lubrication.

First loosen the generator fixing screw and the generator tightening adjustment screw. belt, push the generator against the engine to increase the distance between the pulleys.read short,
Then put the belt on and straighten it, adjust the tightness of the belt to the appropriate level, and tighten the motor mounting screws and adjusting screws.
Preparation before starting the unit:
1. Check the lubricating oil level, coolant level and fuel quantity;
2. whether there are oil or water leaks in various pipelines and joints of oil, lubrication, cooling and other systems;
3. Check the electrical circuits for leakage hazards such as broken skin, loose ground wires and electrical circuits, and whether the unit and foundation are solid;
4. If the ambient temperature is below zero, a certain proportion of antifreeze should be added to the radiator;

5. The diesel generator is started for the first time or when restarting after a long shutdown, you must first use ado manual pump to drain air in the fuel system.

Operating procedures
1. Before you start, check whether there is enough oil in the fuel tank, each oil pipe. and gaskets There is no oil leak; the water in the cooling system is sufficient, clean and leak-free, and the fan belt is properly tightened.
Check that the transmission parts of the internal combustion engine and generator should be reliably connected, the output line wires should be well insulated, and all instruments should be complete and efficient .
2. After starting, it should run at low speed for 3-5 minutes. The operation can only be started after the oil temperature and pressure are normal.
The generator should not emit any abnormal noise when increasing the speed,slip ring and commutator brushes should be in good contact and there should be no jumps or sparks. After the operation is stable and the frequency and voltage reach the rated values, power can be supplied externally.
3. When abnormal noise, odor, sharp increase in water temperature, sharp drop in oil pressure, etc. occur. occur during operation, the machine should be stopped immediately for inspection and troubleshooting.
4. The generator power factor should not exceed 0.95 in late phase (lag). The variation range of the frequency value should not exceed 0.5 Hz.
5. Before shutdown, you must first turn off the main switches of each power branch, gradually reduce the load, and then turn off the main power switch of the generator.
5. p>Return the excitation rheostat to the resisting positionmaximum voltage, reduce the voltage to the minimum value, then turn off the excitation switch and the neutral point grounding switch, and finally stop the operation of the internal combustion engine.
