The fuel consumption of this car is different depending on engine sizes and different configurations. There are many factors that affect actual fuel consumption. It is different for everyone on different sections of road and at different times. You can refer to:
Factors affecting fuel consumption
1. That refrigeration and air conditioning be used
2. Driving conditions, the most fuel efficient are constant speed and economical speed.
3. Weight of the vehicle, the lighter it is, the more fuel efficient it is
< p>4. The higher the electricity consumption, the higher the magnetic resistance of the generator.5. Driving habits, braking too much will definitely not save fuel.
6. The best engine temperature is around 70 degrees. If it is too low, the viscosity of the oil. will be high and thelubrication will not be good. When the temperature is too high, oil adhesion is poor and lubrication is reduced. At the same time, the cooling fan turns on, which consumes energy and then oil.
7. Engine oil performance
8. Tire strength, wide tires have greater strength and the resistance also increases when they are short of air
9. Study on aerodynamics of body design
10. Vehicle Life
Actual overall fuel consumption is related to multiple factors such as load, road conditions, driving habits, weather, wind speed, tire pressure, etc. Actual overall fuel consumption is based on actual driving conditions.
What are the four screws on the alternator skin of JAC Ruifeng S2?
The whole vehicle of JAC Ruifeng S2 may not be under tensionsion for the following reasons:
p>1 If there is no power throughout the car, the battery may be in a low-power state. Check if the battery power is low and recharge the battery to restore it.
2. The power of various electrical equipment in the car is too large, which affects the circuit and damages the battery. In this case, the entire car will not be turned on.
3. The car's generator breaks down. The main power system comes from the battery and generator. Once the generator fails, power transmission will be impossible.
4. The car's fuse is blown, which will cause the entire car to lose power.
Engine noise problem?
Crankshaft pulley, water pump pulley, generator pulley and compressor pulley.
1. Crankshaft pulley: The power source is locked, and the rotationone of the belt is ensured by this pulley.
2. Water pump pulley: achieves circulation of cooling water inside the engine by rotation.
3. Generator Pulley: Rotates the generator to provide additional power to the vehicle.
4. Compressor Pulley: The compressor operates by rotation, supplying low-temperature refrigerant to the air conditioner and reducing the temperature inside the car.
Where is the JAC S2 engine number
1. The motor makes a whistling sound, which sounds like steam or air coming out of the motor. Typically, after hearing this sound, the engine will quickly lose motivation. Possible problem, engine overheats, check cooling system. The exhaust system is clogged, the suction pipe is leaking or broken.
2. When I stepped on the accelerator, I found that the acceleration was not obvious, there was a mlack of power and the engine was making a hysterical noise. The times most likely to occur are when the engine is hot or cold, or when it is low on oil. The causes of these problems can be divided into air filter, spark plug, ignition wire, gasoline, fuel filter, carburetor, oil pump and other problems. Check if the air filter is dirty, if the spark plug is old and needs to be replaced, if the ignition coil is broken, and if the gasoline is not clean, such as water in the fuel line. 'oil. Also check the oil pump.
3. A very loud noise comes from the exhaust, which is very annoying. Sometimes a similar noise comes from the front. The main problem is the exhaust system. Check if the exhaust pipe is broken.
4. The motor makes a kicking sound, like the sound of a pencil hitting the table. The sound increases as engine speed increases. LA 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, acceleration is normal and ignition may be normal. However, if you drive at a constant speed, you notice that the engine speed is too high but the speed still seems to be. unable to increase. Try checking the coolant. Oil pressure is too high or too low. Check the pressure gauge. There may be a problem with the ignition time setting, which may also cause such symptoms. As with others, it could be an internal problem with the engine, such as a clogged EGR valve.
6. When the motor is running, it makes a clicking sound, as if something is hitting metal. When accelerating or driving, you may not hear anything. This may be caused by the engine valve.uelle, which can be changed by adjusting the valve. Lack of engine oil can also cause similar problems and 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 regime changes. The possible reason is lack of power steering oil, fill it up. The generator bearings could be damaged. Problems with the power steering pump and water pump will produce similar noises.
8. When you press the gas pedal, you will hear a clicking noise coming from the exhaust pipe. The sound may not be very loud and the car will not run abnormally, as well as fuel consumption. will increase. It is recommended to check the muffler and exhaust pipe for damage.
JAC Ruifeng S2, Belgian Punch CVT gearbox, manufactured in Nanjing. This model has been used in China for five or six years and is used by many domestic models (such as Geely Emgrand 718). The sales volume is large, the stability is good, and there is no negative news yet. Overall, good value for money. The engine number usually contains information such as engine model, production time and original code, and is important archival information for the vehicle. Each engine has a unique engine number, making it easier for engine manufacturers and vehicle management services to manage vehicle engines. The JACS2 engine number is usually found on the cylinder block. Pay special attention to changing the engine number when repairing or replacing the engine. If you want to buy a used car, youshould also check whether the engine number is complete and consistent, so as not to cause unnecessary trouble when carrying out the relevant procedures for the vehicle. If there is no engine number on the engine block, the engine connection to the transmission may be checked or close to the generator.
