The economic cost of engine braking
1. The rational use of engine brakes is also of great benefit to saving the operating costs of the vehicle. After using the engine brakes, the service life of the brakes and tires is extended. Engine brakes do not need to be specially maintained, and all costs are reduced. 2. Engine braking can improve the speed control of the downhill of the vehicle, and the efficiency of transportation is also effectively improved. (1) When the car is driving on a road with different grades, the proper transmission gear position can be selected, and it is possible to use the engine exhaust brake to slide downhill at a uniform speed without using a service brake. When the truck is driving on the long slope section, the exhaust brake can meet the braking characteristics of low deceleration, long braking time, high frequency, and stable braking performance. Using exhaust brakes can significantly reduce the number of service brakes used. In this way, on the one hand, the service life of the tire is prolonged; on the other hand, the service brake can be kept in a low temperature state to prolong its service life, ensuring that the service brake is sensitive and effective, and that it exerts the maximum braking effect during emergency braking. Exhaust brakes are gentle, which improves ride comfort and reduces driver fatigue. (2) The use of exhaust brake prevents the brake from slipping. Because the exhaust brake is transmitted to the wheels through the differential in the drive train, the braking torque can be evenly distributed to both sides of the wheels, reducing the possibility of truck braking slippage and tail flick on ice, snow and muddy roads. Especially obvious. 3. Use of exhaust brake is beneficial to prolong engine life: The use of exhaust braking, to a certain extent (especially the lower long slope) can prevent the engine from overrunning passively and prolong the service life of the engine; at the same time, the engine runs in the low-speed area, and the vibration and noise are small, which reduces the environmental interference to the driver. . When using a service brake, the temperature of the cylinder surface of the engine will drop more if it is used on a long slope. Under the same conditions, the temperature will drop less, which will improve the thermal state of the engine and help to prolong the service life of the engine. 4. Using the exhaust brake has a fuel saving effect. EDTA is mainly used for Water Treatment, as an additive to Detergent, chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis. EDTA Disodium,EDTA 2NA,EDTA For Preservative HENAN JINHE INDUSTRY CO.,LTD , https://www.hncarbonblack.com
1. High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre poiduction.
2. Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner.
3. Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
4. Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl imide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5. Textile dyeing and printing: EDTA will promote color ability of the dyestuff and brightness of the dyed fabric.
