Meter and gauge

Today I discussed you vehicle meter and gauge system
Vehicle have many meter and gauge which are generate measurement
Some meter and gauge's are

  • Tachometer
  • Speedometer
  • Fuel receiver gauge


Tachometer are used for how many speed at the time of Engine this data send to the car ECM and ECM calculated the data.tachometer is many more types one is fully 360° some tachometer are 180° asper design🚙

Speedometer are used for how many speed wheel rotate,at the time and this data send to to the car ECM ,because some system are depended on this information like ABS ,because abs calculated the cehicle wheel speed at different condition and easy to signify that🚙

Fuel receiver gauge are used for seen the display on combination meter how much quantity of fuel have a car fuel tank,for easily determined the how much kilometre run the vehicle and easily top up the fuel on pump

Some time vehicle fuel gauge meter show on cluster meter car have a fuel but car cannot be start these situation check the tank if it is accidental damage this situation check the tank and float  both as per repair manual,some time cluster meter wrong show some internal problem about fuel capasity,know  more about car meter and gauge 

Vehicle some Part have a different type name

ECM  - 32bit operating system type

Throttle/accelerator padel-noncontact type
Cam/cam position sensor-pick up coil type
 Coolant temperature sensor-thermister type

Abs sensor-Hall IC type
Condenser with receiver drier- Multiflow type


Accelerator padel and throttle body these have a 2 hall IC circuit which are receive and send data from ECM ,if any circuit open or cut vehicle ideal condition knocking and some time ideal running  condition automatically goes off🚙
Today we have problem,vehicle speedometer not working why?I checked some recommended circuit fuse it's ok condition but I checked this circuit earthing ,then see earthing is cut so,i fitted earthing properly and then test a car and problem is gone,car speedometer working normally


Some day ago one car have a problem,problem is car accelerator padel press but not speed the car I checked the car with diagnostic tool and I found some wiring issue,basically car accelerator padel connected through car ECM with throttle body when we pressed accelerator padel vehicle speed goes up and when we release this goes down the speed so accelerator padel and throttle body both have a 2hall IC circuit which generate the current flow as per need if any connection problem then totally system off does not operate normally or throttle valve site out a kit kit noise this happend actually when connection problem,I checked this wearing and found 1 wearing cut in the throttle body side which are send data to the car ECM and I finally repair them and problem solved
So this is a more small problem I discussed about this topic,some time more complicated problem,I discussed with you  hope it is liked you..

N-Channel MOSFET High-Side Drive: When, Why and How?

-
Image
I had previously shown how to drive N-channel MOSFETs in low-side configuration. You can find the tutorial here: http://electel.blogspot.com/2016/12/low-side-mosfet-drive-circuits-and_23.html I’ve been requested to write a tutorial/article regarding high-side MOSFET drive. So, here I’ll talk about N-channel MOSFET high-side drive. Let’s first look at the common low side configuration.  Fig. 1 - N-channel MOSFET configured as low-side switch Now let’s look at a MOSFET configured as a high-side switch. Fig. 2 - N-channel MOSFET configured as high-side switch You can quite easily see the difference between the high-side configuration and the low-side configuration. In the low-side configuration, the load is connected between the drain and +V, while the source is connected to ground. Thus, the gate drive is referenced to ground. So by applying a voltage of >7V (for Power MOSFETs) or >4V (for Logic Level MOSFETs), the MOSFET can be fully turned on. Now let’s talk about the high-si...

Using the high-low side driver IR2110 - explanation and plenty of example circuits

-
Image
In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches. Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110. And in this article/tutorial, I will talk about the IR2110. You can download the IR2110 datasheet from the IR website. Here's the download link: www.irf.com/product-info/datasheets/data/ir2110.pdf First let’s take a look at the block diagram and the pin assignments and pin definitions (also called lead assignments and lead definitions): Fig. 1 - IR2110 block diagram (click on image to enlarge)...

Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

-
Image
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a...
