The fuel consumption of this car is different with different displacements and different configurations. There are many factors that affect the actual fuel consumption. It is different for everyone on different road sections and at different times. You can refer to:
Factors affecting fuel consumption
1. Whether refrigeration and air conditioning are used
2. Driving conditions, the most fuel-efficient is at a constant speed and economical speed
3. Vehicle weight, the lighter the more fuel-efficient
< p>4. Electricity consumption. The more electricity consumption, the greater the magnetic resistance of the generator.5. Driving habits: applying the brake too much will definitely not save fuel.
6. The best engine temperature is about 70 degrees. When it is too low, the oil viscosity will be high and the lubrication will not be good. When the temperature is too high, the oil adhesion is poor and lubrication is reduced. At the same time, the cooling fan is turned on, which consumes power and then oil.
7. Engine oil performance
8. Tire resistance. Wide tires have greater resistance, and the resistance also increases when they are starved of air.
9. Aerodynamics of car body design Study
10. Vehicle service life
The actual comprehensive fuel consumption is related to multiple factors such as load, road conditions, driving habits, weather, wind speed, tire pressure, etc. The actual comprehensive fuel consumption is based on actual driving conditions. allow.
Engine sound problem?
I'm sorry that I just saw your problem. I solved it myself. I have some knowledge about automotive electrical appliances. Because the original generator was too expensive and I was reluctant to replace it with a new one, I dismantled and opened the generator myself. I found that one set of solder joints of the internal rectifier diode was desoldered and seemed to be connected but not connected. I soldered it myself and the problem was solved. I am using it now.
How to install the belt of Ruifeng S2 generator
1. The engine makes a hissing sound, which is like steam or air coming out of the engine. Generally, after hearing this sound, the engine will quickly loss of power. Possible problem, the engine is overheating, check the cooling system. The exhaust system is clogged, the vacuum pipe is leaking, or broken.
2. When I stepped on the accelerator, I found that the acceleration was not obvious, there was a lack of power, and the engine made a hysterical sound. The most likely times to occur are when the engine is hot or cold, or when it is low on oil. The causes of such problems can be divided into air filter, spark plug, ignition wire, gasoline, gasoline filter, carburetor, oil pump and other problems. Check whether the air filter is dirty, whether the spark plug is old and needs to be replaced, the ignition coil is broken, and the gasoline is not clean, such as water in the oil line. Also check the oil pump.
3. A very loud noise comes from the exhaust pipe, which is very annoying. Sometimes a similar sound will come from the front section. The main problem is the exhaust system. Check whether the exhaust pipe is broken.
4. The engine has a kicking sound, like the sound of a pencil hitting the table. The sound increases when the engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and clean the engine. Others may be a valve problem.
5. When driving, the acceleration is normal and the ignition may be normal. However, if you are driving at a constant speed, you find that the engine speed is too high but the speed still seems to be unable to increase. Try checking the coolingIf the oil pressure is too high or too low, check the oil pressure gauge. There may also be a problem with the ignition time setting, which can also cause such symptoms. As for others, it may be an internal engine problem, such as a clogged EGR valve.
6. When the engine is revving, it makes a clicking sound, as if something is beating against metal. When accelerating or driving, you may not hear anything. It may be caused by the cylinder valve, which can be changed by adjusting the valve. Lack of engine oil. Lack of engine oil may also cause similar problems, and the engine oil pressure is relatively low. Check the engine oil pressure.
7. When accelerating, the engine will make a whirring sound, or it will also sound when decelerating. In short, the sound will change as the RPM changes. The possible reason is lack of power steering oil, fill it up. The generator bearings may be damaged. Problems with the power steering pump and water pump will produce similar noises.
8. When you step on the accelerator pedal, you will hear a banging sound coming out of the exhaust pipe. The sound may not be very loud, and the car will not drive abnormally, and the fuel consumption will increase. It is recommended to check the muffler and exhaust pipe for damage.
JAC Ruifeng S2 does not have power supply to the entire vehicle
1. First loosen the generator fixing screw and the belt tightness adjusting screw.
2. Secondly, place the generator of Ruifeng 2 against the engine so that the distance between the pulleys is the shortest, and then place the belt sleeve on the rocking hammer.
3. Finally, adjust the belt tightness to the appropriate level, tighten the engine fixing screws, and adjust the screws.
The JAC Ruifeng S2 may not be powered on due to the following reasons:
1. The entire vehicle may not be powered on. It may be that the battery is running low. Check whether the battery power is sufficient. If the loss occurs, it can be restored by charging the battery.
2. The power of various electrical equipment in the car is too large, which affects the circuit and causes battery damage. This may also cause the entire car to be without power.
3. The car's generator fails. The main power supply system comes from the battery and generator. Once the generator fails, current transmission will be impossible.
4. The fuse in the car is blown, which will cause the entire car to lose power.
