Fuel injection control system Motronic 3.1

Section Car. Electronic fuel injection. This control system includes a fuel pump, fuel pressure regulator, air mass meter with heating element, injectors, throttle position sensor, idle speed control, coolant temperature sensor and knock sensor, engine speed sensor, fuel tank ventilation valve, canister , exhaust gas oxygen sensor (lambda probe), ignition coil and electronic control unit (ECU). Compared to previous Motronic models, this control system is more advanced. Each injector has a separate ECU control channel, which ensures high accuracy of fuel dosing and faster response to changes in engine load. In addition, fuel injection is carried out three times per revolution of the engine crankshaft. ... >>

Attachment to the frequency meter

Section Measuring technology. An attachment to a frequency meter is proposed for determining the resonant frequency of a parallel oscillatory circuit. His circuit (Fig. 1) is well suited for this, because. for feedback, it is not necessary to make a tap from the loop coil. Transistors T1 and T2 (BF244C) operate in an oscillator circuit similar to the well-known cathode-coupled lamp circuit. Cascade on TZ (2N708 or VS547V) - matching ... >>

Improving the parameters of the amplifier on the chip K174UN7

Section Power Amplifiers. The constantly expanding range of specialized microcircuits, it would seem, should limit the creativity of radio amateurs. Indeed, such microcircuits are usually oriented by their developers to solve one specific task in electronic equipment or, at best, a narrow range of tasks. That is why radio amateurs and radio designers seem to be left with only creative games of cubes - combining units on microcircuits assembled according to standard switching circuits ... >>

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
