E Course Network Integrated Editor Integrated Circuit (integrated circuit) is a type of micro electronic device or component. It uses a certain process to interconnect the necessary components such as transistors, resistors, capacitors, and inductors in a circuit, fabricating them on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and … Read more
Common Rail Guide The common rail system requires precise fuel injection from the injector, but due to manufacturing deviations of the injector itself, the control accuracy of the fuel volume can be affected. To overcome this impact, electronically controlled diesel engines commonly use injector correction code technology. This issue will take you into the world … Read more
With the increasing demand for energy conservation, emission reduction, and lower fuel consumption, the engine idle stop-start system has become a relatively quick technology to reduce fuel consumption, decrease emissions, and enhance vehicle appeal, and it is being adopted by more and more manufacturers. What exactly is this seemingly sophisticated technology capable of? Today, I … Read more
ECU tuning is an automotive modification technique that has been imported from abroad. Initially, car owners viewed it as a high-end gadget. Some owners argue that tuning the ECU to enhance power can harm the engine, leading to increased fuel consumption and reduced engine lifespan. They believe sacrificing engine longevity for power enhancement is not … Read more
For those just starting with PLCs, mastering the programming language and understanding instructions is one of the fundamental conditions. Regardless of how different your programming habits are from others, you must learn this element of instructions, as programming cannot do without its components. Below, let’s take a look at the extent of the application of … Read more
The national standard of China (GB7665-2005) defines a sensor as: “a device or apparatus that can sense the measured quantity and convert it into a usable output signal according to certain rules.” Sensors, as an important means of information acquisition, along with communication technology and computer technology, constitute the three pillars of information technology. Below, … Read more
In RS485 communication systems, the choice of grounding method is crucial, directly affecting the system’s stability and anti-interference capability. Therefore, engineers need to choose the grounding method reasonably based on project requirements. Below we will discuss which grounding is suitable for the RS485 bus. 1. Single Point Reliable Grounding There can only be one grounding … Read more
In many tech products, heat sinks may be overlooked as less important accessories. However, in NVIDIA Jetson embedded products, the importance of heat sinks cannot be ignored. This article will discuss a heat sink failure case we experienced. A year ago, a middleman who purchased a batch of NVIDIA Jetson Xavier NX module heat sinks … Read more
