You certainly don't know anything about automobiles!
How much do you know about car maintenance? The following is a combination of car maintenance, driving knowledge and other popular little common sense. Come and see what you know?
I. Driving Skills
The transmission of vehicle power, first from the engine to the gearbox, and then from the transmission shaft to the driving wheel, so that the car forward, the amount of power output, depends on the throttle trample. From the point of view of fuel economy, with the smallest power output and the fastest speed, there will be the highest efficiency.
1. Light refueling, light braking, early braking, strong braking, quick start, and slamming on the throttle are major fuel-saving taboos.
The fuel-saving test shows that it takes two to three times more fuel to step on the throttle than to drive at medium speed. Therefore, under the premise of ensuring the normal driving of the car, the throttle range should be reduced appropriately. When you see the red light on or enter or exit the highway, you can gently step on the brake ahead of time to slow down, and skillfully use the remaining power of the engine to let the vehicle glide forward.
2. Shift timing and gear selection
Shift timing should be between 2500 and 3000 turns as far as possible, so as to ensure power supply and get better economy. In order to eliminate low gear and high speed, when driving a manual transmission, it is necessary to change to high gear in time after the speed has stabilized; while driving an automatic transmission, it is necessary to avoid using the "motion" mode as far as possible. In addition, users of manual gear should stop starting with high gear.
3. Acceleration after warming up
Engine running at low temperature is more fuel-intensive than running at elevated temperature, so don't accelerate immediately when you start, but slow down for a few minutes to let the engine warm up and then speed up.
4. Grasp the Economic Speed of Vehicles
Economic speed refers to the most fuel-efficient driving speed. Different types of vehicles have different economic speeds. Careful reading of the vehicle instructions, but roughly 70-90 km/h. If the speed is lower or higher, the fuel consumption will increase.
5. Pay attention to the running-in period of new cars
Whether the driving method during running-in period is correct or not will have a great impact on the fuel economy of the engine in the future. Therefore, we must bear in mind the driving principles of the new car during the running-in period when the speed does not exceed 80 kilometers per hour and the speed does not exceed 4000 revolutions. Never break the ring.
6. Rational Use of Air Conditioning
When the temperature is suitable, when the speed is less than 60 kilometers per hour, windows can be opened for ventilation, instead of air conditioning, or only use the ventilation function of air conditioning, instead of using its refrigeration function, so that the air conditioning compressor will not start, thus saving oil. However, when the speed is higher than 90 kilometers per hour, it is not recommended to open windows for ventilation, because the air resistance is very high at this time, air conditioning is more fuel-efficient.
II. Maintenance Chapter
Regular maintenance of automobiles is very important. If the tire is deflated, the spark plug is worn out, and the air filter is blocked, it will cause gasoline consumption.
1. Check tire system carefully
Insufficient air pressure will increase friction between tires and the ground and increase fuel consumption, so check tire pressure frequently. Different models and tires have different air pressure standards. In addition, if the tire wears seriously, there will be skidding phenomenon, and will increase fuel consumption, if necessary, to replace the tire.
2. Pay attention to checking brake system frequently
Some cars will have slight drag brakes, including hand brakes, which will increase the load of the car and fuel consumption. Therefore, regular checks should be made.
3. Load reduction
Statistics show that each additional kilogram of load will increase fuel consumption by 1%, so it is necessary to minimize unused debris in the reserve compartment.
4. Regular maintenance and replacement of spare parts
Air filters, gasoline filters, oil filters and so on need to be replaced for more than 5000 kilometers of driving, because air filter blockage will cause a reduction in gas flow, resulting in inadequate combustion of gasoline and reduced fuel efficiency. The wear of clutch plate and clutch pressure plate, the spark plug used for too long, will also appear the phenomenon of increased fuel consumption, so it should be replaced regularly.
3. Misunderstanding of Driving Knowledge
1. Vacuum can save fuel
Early carburetor trucks could save fuel by putting out neutral gear, but now we use EFI trucks are not. Because some cars unlock the throttle in acceleration, the fuel injection system stops supplying and resumes supplying when the engine speed drops to 2000 rpm, the fuel will be saved when the EJV slides at high speed with block, and the empty gear will consume oil instead.
2. The higher the octyl value of gasoline, the better
Gasoline for each type of car is usually marked on the instructions. Now many car owners often think that the better the oil is, the better the car is. In fact, it is not. It is not only expensive to use higher quality oil than the vehicle itself, but also has a negative impact on the engine.
3. Long idling
The fuel-saving test proves that the fuel consumption of engine idling for 3 minutes can make the car travel 1 kilometer. Therefore, if the detention time exceeds 1 minute, the flame will be extinguished. But restart often consumes 20% more fuel than normal driving, so idle speed should be chosen for short parking.
