Roewe 350 manual, 1 5 liters of fuel consumption in daily practical use

I'll tell you about the actual fuel consumption of my Roewe 550:

On the morning of April 29th, I picked up the car, Qiyi version.

According to the numbers on the computer display screen: a total of 366 kilometers have been run in these ten days, and the total mileage is 368 kilometers.

The average fuel consumption is.

Yes or at idle.

The average speed is about 17 or 19 per hour (I can't remember exactly, I'll see again tomorrow).

The traffic situation is in the city, which is a congested area, and the longest traffic light at the intersection is five green lights before passing.

Because it is a new car, every time I drive, I dial the fuel consumption display to see the instantaneous change in fuel consumption and find the pattern.

I am very satisfied with this car, many friends have test driven my car in the past few days, and they all feel good, it seems that the actual fuel consumption is not at all like what many people on the Internet say. Suggestion is definitely buyable!

If you haven't started manually, don't buy it.,Wait 3 months later.,There's a problem with the gearbox.,Now it's improving.,Don't accept orders for the time being.。 Automatic ones are fine. 350 has to go up to 2000 to feel the force, and below 2000 is very meaty.

It's not bad to drive in the city. Fuel consumption is about liters.

Roewe 350 has high fuel consumption, and there are several reasons that need to be checked. In the first case, it is necessary to check whether the spark plug is caused by too large a gap. The second case needs to be checked, the fuel injector atomization is not good.

caused by this situation. Or the gasoline pressure is too high, and the normal gasoline pressure is around the right. The third case is to check whether there is a problem with the sensor itself, for example.

This condition is caused by eczema by air intake flow sensors as well as oxygen sensors. I hope this service can help you, if it is helpful to you, I look forward to your praise and attention. The car master is here to help.

How to deal with the high fuel consumption of Roewe 350.

How to deal with the high fuel consumption of Roewe 350.

Hello. I am your exclusive technician, attentive, careful, attentive to answer your questions, I hope this service can help you. Roewe 350 has high fuel consumption, and there are several reasons that need to be checked.

In the first case, it is necessary to check whether the spark plug is caused by too large a gap. The second case needs to be checked, the fuel injector atomization is not good. caused by this situation.

Or the gasoline pressure is too high, and the normal gasoline pressure is around the right. The third case is to check whether there is a problem with the sensor itself, for example. This condition is caused by eczema by air intake flow sensors as well as oxygen sensors.

Fuel consumption in urban areas is more than 12.

Check out the reasons I mentioned.

The actual fuel consumption is, and the fuel consumption given by the manufacturer under working conditions is. Fuel consumption, commonly known as the fuel consumption of a car after 100 kilometers.

Factors that affect fuel consumption include: environmental conditions, road surface, driving conditions, number of passengers or cargo weight, tires and tire pressure, and driver's driving habits.

The factors that affect fuel consumption are as follows:

Environmental conditions. Formal testing is conducted at a controlled atmospheric temperature, with a laboratory temperature of 20 5, while the actual ambient temperature generally varies between -30 and 40. Low temperatures make it take longer for the vehicle to warm up the engine and consume oil.

Driving conditions. The official fuel consumption test is carried out under typical driving conditions and consists of two parts: the urban low-speed driving condition (top speed of 50 km/h, average speed of 19 kmh) and the suburban high-speed driving condition (top speed of 120 kmh, average speed of about 63 km/h). However, the actual user's place of use and the working conditions of the vehicle are very different, and the main reason for the large difference in measured fuel consumption lies in this.

When driving in urban areas, the fuel consumption of the vehicle is higher. Low fuel consumption when driving normally on the highway; Frequent short distances also consume fuel as the vehicle runs less time at ideal temperatures.

Empty key. Air traffic regulations have a significant impact on the fuel consumption of automobiles. At present, the official fuel consumption test in China is carried out in the case of empty off, but in the actual driving situation, the fuel consumption of setting empty in the maximum gear is 5 25% more than that when it is turned off.

The U.S. requires the no-switch to be turned on for the evaluation test of automobile fuel consumption, which is worth learning.

Number of passengers or weight of cargo.

Vehicle weight has a significant impact on the fuel consumption of a car. The official fuel consumption test is carried out under the following benchmark conditions: the weight of the vehicle and the empty weight of the vehicle (including the necessary tools, spare tire and fuel) plus 100kg (including the weight of the driver).

But in actual use, the number of passengers is large, and when the trunk is full of goods, the fuel consumption of the car is bound to be large. So you can save fuel and tire pressure by minimizing things you don't have to bring in the car.

Different tires have different rolling resistance, and the rolling resistance is greater when the tire pressure is low. Therefore, if the user changes the tire or the tire pressure is too low, the measured fuel consumption of the vehicle may differ from the official test value.

Personal driving habits.

The formal test is carried out with a skilled driver operating the vehicle according to normal acceleration and deceleration. In actual use, the driver's driving habits may lead to a large difference in the fuel consumption of the vehicle.

The reasons and solutions for the high fuel consumption of the Roewe 350 manual transmission are as follows. 1. Affected by the temperature, the fuel consumption increases, and the situation is normal. In most winters, when the temperature is low, the fuel consumption is basically larger, which is about the same as when the air conditioner is turned on in the summer.

This is because the temperature is low, and the amount of heat released by the engine increases. Secondly, it takes a long time to warm up the car in winter, and it takes time and more gasoline from starting to the normal water temperature. 2. The vehicle has not been maintained for a long time.

If the oil and air cleaner are dirty, it may also increase fuel consumption. Oil contamination can lead to poor lubrication, increased resistance to the moving parts of the engine, and a lot of energy is required to overcome the resistance, worsening fuel consumption. Regular vehicle maintenance is required.

3. Spark plugs. Spark plugs are easy to overlook. There are also vehicles that have not been replaced even after driving hundreds of thousands of kilometers.

When the life of the spark plug is up, it can still be used, but due to the lack of ignition energy, the ignition is delayed, and the optimal ignition period is missed. For example, gasoline should be ignited when the piston is close to the top dead center, but the ignition energy is insufficient, it is difficult to ignite, and the piston starts to move downward and then ignition, which will lose part of the power, resulting in a lot of energy that cannot be used for work, and at the same time the combustion is not smooth. 4. Insufficient air pressure.

Insufficient air pressure will affect the contact area between the tire and the ground to become larger, and the friction force will increase, that is, the driving resistance will become greater and the fuel consumption will increase. Insufficient air pressure may reduce the life of your tires, and driving at high speeds can also increase the probability of a puncture. The tire pressure section must be maintained regularly, and it must be inspected every two months at most.

If there is tire pressure monitoring, it can be checked directly, and if there is no tire pressure monitoring, each tire is measured manually. 5. The data of some sensors such as water temperature sensor and oxygen sensor are inaccurate. It's just that the sensor is not completely damaged, the data is not accurate, the fault indicator does not necessarily illuminate, and it is very difficult to notice even if the data stream is not checked by a computer.

For example, if the temperature of the water temperature sensor is low and the oxygen sensor shows too much oxygen, in most cases, the computer must be adjusted to multi-injection fuel, which ultimately affects the incompleteness of combustion, increases fuel consumption, and regularly maintains the sensor data. 6. Excessive carbon deposition in the vehicle. The carbon deposition is the throttle, fuel injector, intake channel, and piston top, and the excessive carbon deposition anywhere basically affects the combustion exhaustion, which in turn affects the increase of fuel consumption, and the vehicle carbon deposition needs to be removed.

The Roewe 350 is a compact sedan launched by SAIC Motor after the Roewe 750 and Roewe 550 for the A-segment market, and it is also the first family sedan to incorporate 3G technology.

So, how to look at the fuel consumption of the Roewe 350, and what to do if the Roewe 350 has high fuel consumption? Let me explain it to you.

Roewe 350 can see the average fuel consumption from the information center of the dashboard, but the average fuel consumption is calculated from the engine start, it is worth mentioning that the fuel consumption of the vehicle is related to the driver's style, the driving conditions of the vehicle, the load of the vehicle, the tire pressure, the power of the vehicle electrical appliances, and the oil product.

What should I do if the fuel consumption is high? We can change the following driving habits in our daily driving:

1. Avoid engine idling for a long time.

The fuel consumption of the engine when parking and idling is much greater than that during normal driving, so it is best to turn off the engine when the vehicle is not started for a long time, such as when parking and waiting for someone.

2. Avoid sudden braking as much as possible.

A gentle, smooth driving style is the most fuel-efficient, in the initial stage, try to avoid slamming on the accelerator, the correct way is to accelerate smoothly, and after reaching a certain speed, you should maintain a constant speed as much as possible. When driving on congested roads, also look at the road ahead and avoid braking suddenly. In this way, not only does it save fuel, but it also extends the life of the vehicle.

3. Maintain an appropriate driving speed.

4. Do a good job of daily maintenance.

Unclean air and oil filters, worn spark plugs, and problematic emission control systems can all increase fuel consumption. According to statistics, it is normal for a poorly maintained engine to increase fuel consumption by 10% or 20%, and an air filter that is too dirty can also lead to a 10% increase in fuel consumption. To maintain the optimal performance of your car, it is best to change the oil every 5000 kilometers and check the filter.

5. Choose a reasonable route.

When stuck in traffic, the fuel consumption of the car is the maximum. Therefore, in large cities, congested roads should be avoided as much as possible. For example, choosing a high-speed loop that goes around the city is much less fuel-efficient than a straight road through the city center.

6. Reduce the burden on the car.

Cleaning up unnecessary things in the trunk can reduce the weight of the car and also achieve the effect of saving energy.

The reasons for high fuel consumption may be:

1.Poor ignition.

The spark plug gap is too large, and the ignition coil energy is not enough.

2.Poor atomization of the fuel injector.

The fuel pressure regulator is faulty and the fuel pressure is too high.

3.The engine has too much carbon deposit.

A portion of the gasoline sprayed is absorbed by carbon deposits.

4.Sensor failure.

For example, a faulty water temperature sensor can cause the engine to be mistaken for a cold car and send out a fuel injection signal all the time, resulting in high fuel consumption.

5.Oxygen sensor malfunction.

The fuel correction will fail, the computer will always send a fuel injection signal, and the air flow meter will cause the intake data to be incorrect.

The Roewe 350 can see the average fuel consumption from the dashboard's information center, but the average fuel consumption is calculated from the engine start. It is worth mentioning that the fuel consumption of the vehicle is related to the driver's style, the driving conditions of the vehicle, the load of the vehicle, the tire pressure, the power of the vehicle's electrical appliances, the oil and other factors.

What should I do if the fuel consumption is high? We can change the following driving habits in our daily driving:

1.Avoid turning the engine empty for a long time.

At idle, the engine's fuel consumption is much higher than when it is on normal driving. So when the vehicle does not start for a long time, such as parking, it is better to turn off the engine.

2.Avoid sudden braking as much as possible.

A gentle and smooth ride is the most fuel-efficient. In the initial phase, try to avoid stepping on the accelerator. The correct way to do this is to accelerate smoothly, and after reaching a certain speed, try to maintain a constant speed.

When driving on congested roads, also see the road ahead clearly and avoid braking suddenly. This not only saves fuel but also extends the service life of the vehicle.

3.Maintain an appropriate driving speed.

4.Do routine maintenance.

Unclean air and oil filters, worn spark plugs, and defective emission control systems can all increase fuel consumption. According to statistics, it is normal for a poorly maintained engine to increase fuel consumption by 10% or 20%, while an air air filter that is too dirty can also lead to a 10% increase in fuel consumption. In order to maintain the optimal performance of the car, it is best to change the oil every 5000 km and check the filter.

5.Choose a reasonable route.

When there is a traffic jam, the fuel consumption of the car is the largest. So in big cities, try to avoid taking congested roads. For example, the high-speed loop around the long road has much lower fuel consumption than the straight road through the city center.

6.Reduce the burden on your car.

Cleaning up unnecessary things in the trunk can reduce the weight of the car and save energy.
