As the saying goes, "you can afford to buy a car, you can't afford to drive a car", which means that the fuel cost is high. For high displacement cars, the fuel consumption is certainly higher. So, how to save fuel? What are the fuel saving skills? Now, let's take a look at how to save fuel by driving!
When it comes to fuel economy, many car owners are interested in it. How can we save fuel by driving? The following will reveal the answer for you, let's have a look!
First: insufficient tire pressure, fuel consumption increased by more than 1%
If the tire pressure is 2 psi lower than the specified value, the fuel consumption will increase by 1%. The offset or excessive wear of tires may also increase fuel consumption.
Maintaining a normal tire pressure level is also a good way to reduce fuel consumption. If the tire pressure is insufficient, it will greatly increase the rolling resistance.
Second: do not maintain the engine more than 10% fuel consumption
Some car owners maintain their cars once a year. In fact, this is not right. Domestic engine oil usually has half a year's shelf life and begins to deteriorate after half a year.
Abnormal ignition system also has a great impact on fuel consumption, such as inaccurate ignition time, leakage of high-voltage wire, weak ignition caused by carbon deposition in spark plug, which will reduce combustion efficiency and increase fuel consumption.
The engine oil consumption may increase by 10% or 10% due to dirty air filter.
In order to maintain the best performance of the car, it is best to change the oil every 5000 km or half a year and check the filter.
Third: low gear and high speed consume 10% more oil
Low gear and high-speed driving, which often occurs in novice drivers, but also often occurs in drivers who are easy to distract themselves.
If you drive at a high speed, the fuel consumption will increase by 10% if you use a third gear instead of a fourth gear. There is also a case of unnecessary high-speed driving, technician introduction: any car has an economic speed, the most fuel-efficient driving at this speed, below or above this speed, fuel consumption will rise, and then more than a certain speed, fuel consumption will rise significantly.
Fourth, the maintenance is not heavy
Due to the lack of car knowledge, many riders only focus on keeping the car clean, while other aspects are often ignored. In fact, scientific maintenance can make the car achieve the purpose of fuel saving. For example, the wheel bearing should be oiled on time, but some car owners don't know until the bearing is worn out.
If the wheel bearing is short of oil, the friction will increase and the fuel consumption will also increase; if the brake of some cars does not return, the brake pad and brake drum are in a friction state, so the fuel consumption will naturally increase; if the wheel alignment is abnormal, the abnormal wear of the tire will also cause the increase of fuel consumption.
Fifth: wrong driving, 2 to 3 times more fuel consumption
Incorrect driving habits have the greatest impact on fuel consumption. In the process of driving, especially when the traffic is not smooth, waiting for red lights and changing lanes, the problems of rapid acceleration and braking are the most common.
Experts have done accelerated driving fuel consumption test, let the vehicle drive at a constant speed into the test section, the tester will step on the accelerator to drive to the end, after completing the specified distance, found that the fuel consumption is increased by 2 to 3 times than the constant speed driving. If the vehicle runs in low gear for a long time, it will inevitably increase fuel consumption.
The fuel consumption is greatly increased by slamming, braking and accelerating. Driving habits are very important.
Sixth: the engine has carbon deposit, do you know
Excessive carbon deposition is mainly caused by the use of poor quality engine oil, in which unsaturated hydrocarbons and colloidal impurities in the high temperature state produce coke like substances, which will make the intake pipe wall rough, affect the intake effect and mixture quality, and make the fuel consumption rise sharply.
So it's best to clean up carbon every six months.
Don't clean up, remember: don't use high-end low-speed driving, run a long distance once a month.
Seventh: oxygen sensor
After a long time of use, the oxygen sensor is prone to silicon poisoning. Once it happens, the computer of the electronic fuel injection system can not get the information of the oxygen concentration in the exhaust pipe. The mixture concentration in the engine is often on the high side, and the fuel consumption will also increase.
At the same time, in the case of power shortage, the oxygen sensor and fuel injector can not work normally, the mixture is too rich, and the fuel consumption will go up. It usually needs to be replaced at 80000-110000 km.
Eighth: the battery, the total loss of electricity, always have to charge, must have
The storage battery is an oil tiger. You must have never thought of it.
In fact, the relationship between circuit and oil circuit is beyond imagination. When the service life of the battery reaches 2-3 years, there will be a power loss phenomenon, which will lead to insufficient starting voltage, the motor driving engine is relatively weak, and the spark plug can not jump out of the strong and powerful spark, so that the ignition energy will be reduced, and the fuel consumption will soar.
Ninth: clutch slip, often half clutch attention
Clutch slip will cause the engine to lose revolutions.
When you accelerate rapidly, you find that the engine tachometer increases rapidly, but the speed increases slowly. At this time, you can judge that the clutch is slipping.
The clutch plate, pressure plate and driving wheel need to be replaced.
Tenth: the car is too heavy
Some riders regard the trunk as a warehouse. Whatever is useful or useless is crammed into the trunk, which increases the weight of the car. However, the relationship between the weight of the car and the fuel consumption is proportional. It is said that every 10% decrease in the weight of the car will lead to a corresponding decrease in fuel consumption by several percentage points.
Especially for office workers, female compatriots, the car is a small warehouse, which can clean up unnecessary supplies and reduce the burden of car.
11th: automobile air conditioning
Turning on the air conditioner will increase fuel consumption by a quarter. This is big data. When it's unnecessary, try to turn it on as little as possible, right?
Conclusion: basically, people who make do with buying a car save on driving because they are afraid of fuel consumption. The above is Xiaobian's summary about how to save fuel while driving. I believe many car owners are beginning to get excited. You might as well try Xiaobian's recommendation! Hope Xiaobian's recommendation can help you!
