Bosch has recently developed a taxi start-stop system that helps to save fuel. Unlike the current start-stop system , which only shuts down the engine when the vehicle is completely stopped, the taxi start/stop system can shut off the engine when the vehicle is coasting (eg, High-speed downhill) At the same time, the use of a control system in the automatic transmission models automatically controls the clutch, which separates the engine from the driveline to extend the gliding distance. When the driver is operating the accelerator or brake pedal during taxiing, the engine will start quickly.
Compared to the current start-stop system, the composition and structure of components of the taxi start-stop system will not change, but due to the addition of the start-stop mission under taxi conditions, system work will be more frequent, in terms of some key components, such as starter And batteries need to be optimized according to the actual situation.
The existing engine control system can also realize the gliding of the vehicle with a gear, so why develop a taxi start-stop system? What are the advantages of the taxi start-stop system? Bosch explained that although the vehicle can coast with glide, on the one hand the engine and transmission are not separated and the taxi distance is not long. On the other hand, when the air is coasting, the engine will still inject oil. Although it can slide long distances, it cannot reach the festival. The purpose of the oil. The taxi start-stop system can combine the advantages of these two operating conditions to achieve the purpose of fuel economy through flameout and at the same time make the taxiing distance longer.
Bosch's research and testing found that 30% of the engine's daily running is unnecessary, and about one-third of the time during the running process can be gliding. Therefore, in the actual traffic, the taxi start-stop system can help the vehicle to reduce the fuel consumption by 10% on the basis of the existing start-stop function.
Air Separation Unit & Air Separation Plant
The basic principle of air separation is use cryogenic rectification to condense air into liquid and separate the air according to the evaporation temperature of each component. The two-stage rectification tower simultaneously obtains pure nitrogen and pure oxygen at the top and bottom of the upper tower. It is also possible to take out liquid oxygen and liquid nitrogen from the evaporation side and the condensation side of the main cooling respectively. The air separation in the rectification tower is divided into two stages, air is separated for the first time in the lower tower to obtain liquid nitrogen and at the same time obtain oxygen-enriched liquid air. The oxygen-enriched liquid air is sent to the upper tower for rectification to obtain pure oxygen and pure nitrogen. The upper tower is divided into two sections: with the liquid-air inlet as the boundary, the upper part is the rectification section, which rectifies the rising gas, recovers the oxygen component, and purifies the nitrogen purity, and the lower section is the stripping section to remove the nitrogen components in the liquid, separated to improve the oxygen purity of the liquid.
According to the set control sequence, the whole set of oxygen production system starts and stops automatically with one key, and unattended and realize automatic start and stop and remote monitoring. All control and operating parameters are displayed on the industrial computer.Air Separation Unit , Air Separation Plant
