Diagonosis

Today have a problem car normal start and run and when vehicle coolant tempareture high and electrical fan on this situation vehicle knocking and off how to fix this problem?

We checked the vehicle totally as per manual first check vehicle air filter condition,next all vacuume hosses which are fitted on brake booster to tappet cover,tappet cover purge control valve to MPFI (Multi point fuel injection) system and which are fitted in pcv valve side ,it's ok condition no air leakage on this pipe,next check throttle valve condition,we see throttle valve have a more dirt perticle insode,so we first clean them,and next check igniation on and accelerator padel full close and full open condition throttle valve angle geometry ,next check Electric  throttle valve resistance

and check pcv valve resistance it's ok condition next check the fuel pressure fuel pressure ok but we also check the fuel filter condition,filter condition are bad so I replace the fuel filter and check the car in test drive and finally the problem out
This type of problem is more on a petrol car and main reason is most time fuel filter and pump so if u you face on a same situation check the system this way ..... 🚙
Vehicle have a more problem need a diagnosis in best way for good result
See auto tutorial.....

Next diagnosis about fuel sediment light glowing on vehicle cluster meter 

We checked first fuel filter sight where sediment coupler fitted on,we check and found fuel sediment coupler sight wiring cut for fuel sedimental light glowing but of wiring is ok condition first check fuel filter condition if bad /poor quality fuel enter the system then fuel sedimental light glowing ,if fuel is mixed with water first replace the fuel filter and next clean the fuel tank frequently it necessary

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 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...

Using the TLP250 Isolated MOSFET Driver - Explanation and Example Circuits

-
Image
I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...
