Do not place your feet on the pedals while you are driving. Otherwise, the brake pads will be in a state of friction for a long time and they will become hot and even wear out, increasing fuel consumption. Here's how to use brakes flexibly.
1. Reasonably control the speed of the vehicle and try to use predictive braking
Since the braking distance is proportional to the square of the vehicle speed, under the premise of ensuring safety, reasonable control of the vehicle speed can be quick and fast, and the speed is slow, so as to avoid being caught off guard in case of distress.
Use predictive braking as much as possible, that is, make mental preparations in advance according to changes in road traffic conditions, and purposefully adopt deceleration or parking measures. The method is: When discovering the situation, should release the throttle first, stop the oil supply, use the reaction force that the cylinder compresses when the engine is idling to reduce the speed of the car, can also press the brake pedal appropriately according to the situation at the same time, make the speed of the car further reduce, in addition, can Determine whether to release the brake according to the change of the road conditions in front; when the danger disappears, the brake can be released; otherwise, the brake pedal should continue to be depressed to further reduce the speed; when the speed drops to a certain level, the clutch pedal should be stepped on quickly. It will not stall but it will stop smoothly at the scheduled place.
2, good at using the engine to prevent braking
When a locomotive is running downhill, especially on a long steep slope, in order to avoid frequent use of the brakes, the friction plates will overheat and ablate and the brakes will fail; or when the locomotive is driving downhill on slippery roads such as mud, ice and snow, the engine shall be used to prevent skidding. brake. The method is: release the throttle, do not step on the clutch pedal, and do not use other braking measures, relying solely on the role of the engine pull, forcing the vehicle speed to reduce, so as to achieve the purpose of braking. Because the engine braking is based on the resistance of the locomotive to force the engine to accelerate the rotation generated by the resistance to achieve the use of the resistance, this resistance mainly from the piston and the cylinder wall and the crankshaft and the bearing friction. Therefore, the lower the engine braking combined gear is, the faster the engine speed is at the same driving speed, and the more energy the engine resistance consumes, the better the pinning effect is. If necessary, you can override the brake.
3, more use of brake
When the vehicle speed is high, the vehicle will slip sideways or even flick the vehicle when the brake is too fast, especially on muddy, icy and snowy roads. Therefore, when the vehicle speed is high, point braking should be used as much as possible. The method is: when the clutch is not disengaged, the brake pedal is properly stepped on, and thus intermittently, the vehicle speed is reduced. When braking, it is necessary to make the braking force as close as possible to the actual needs. Do not use too much force to make the wheels in a critical state that seems to be turning, in order to exert maximum braking force. 4. Use emergency braking only when absolutely necessary
When the vehicle encounters a sudden emergency during driving, emergency braking can be used as a last resort to stop the vehicle as soon as possible. The method is: firmly hold the steering wheel, quickly release the throttle, immediately step down the brake pedal, if necessary, should quickly tighten the parking brake, give full play to the vehicle's braking ability, so that the vehicle immediately stopped. Because of the emergency braking, some parts of the locomotive, especially the tires, will cause great damage, and often due to inconsistent left and right wheel braking forces or different adhesion coefficients between the left and right wheels and the road surface, it is easy to cause vehicle deviation, side slip or wheels. Being locked and losing control of direction, it is prone to crashes or overturning accidents. Therefore, emergency braking is the last resort to use when there is no choice.
Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
