The main difference between diesel engines and gasoline engines in electronically controlled injection is that the electronically controlled injection system of gasoline engines only controls the air-fuel ratio (the ratio of gasoline to air). The electronically controlled injection system of diesel engines regulates the output size by controlling the injection time. Diesel fuel injection control is determined by the engine speed and accelerator pedal position (throttle lever position). Therefore, the basic working principle is that the computer first calculates the basic fuel injection quantity based on the input signals of the speed sensor and the throttle position sensor, and then corrects the signal according to the sensors such as the water temperature, the intake air temperature, the intake pressure, and then from the control sleeve position. The sensor signal is feedback-corrected to determine the optimum fuel injection. The electronically controlled diesel injection system consists of sensors, ECUs (computers) and actuators. Its task is to electronically control the fuel injection system, realizing the real-time control of the fuel injection quantity and timing of the fuel injection with operating conditions. Sensors such as rotation speed, temperature and pressure are used to simultaneously input real-time detection parameters into the computer and compare them with the stored parameter values. After processing and calculation, the fuel injection pump, exhaust gas recirculation valve and glow plug actuators are executed according to the optimal values. Control, drive the fuel injection system, so that the best operating state of the diesel engine.
Black Goji Berry is rich in protein, fat, sugar, free amino acid, organic acids, minerals, trace elements, alkaloids, vitamin C, B1, B2, calcium, magnesium, copper, zinc, manganese, iron, lead, cobalt, nickel, cadmium, chromium, potassium, sodium and other nutrients. Been scientifically tested that the content of calcium, iron, niacin is respectively 2.3, 4.6, 16.7 times of red Goji Berry, especially procyanidins than blueberries(Black goji berry contain procyanidins is 3690 mg / 100 g; blueberries contain procyanidins is 330-3380 mg / 100 g). This is the highest ever discovered procyanidins content of natural wild fruit, which is the most effective natural antioxidant, its efficacy is 50 times of VC and 20 times of VE, the vitamins, minerals and other nutrients content is also higher, medicinal and health care value is much higher than ordinary red Goji berry, known as "soft gold".
