S.I & C.I ENGINE DEFINATION

     

 ** S.I Engine

                      S.I means spark ignition engine,and these engine are also called petrol engine, these type engine have a spark plug for sparking the air fuel mixture on cylinder,each cylinder have a one spark plug some engine have a two spark plug these engine name is (DTSI--DIGITAL TWIN SPARK IGNITION ENGINE) engine.
     *** Petrol engine are more smooth because petrol fuel ignition capability is too much high, easy to burn the air fuel mixture🙂


         MPFI-- Its a four cylinder MPFI engine.


**C.I engine


        C.I engine full form is Compressed ignition engine, and it is used in Diesel vehicle, it's work on "compressed air" and "pressurised fuel" for firing in each cylider., Compressed air and pressurised fuel use because dielsel ignition capability is low,this why it's need a turbo charger and EGR for pressurised air and fuel pump used for pressurised fuel and high pressure pipe line also,
  ** These engine are mostly used in commercial vehicle


 

  Compare between S.I and C.I engines

   

       1) S.I engine generate a Homogeneous mixture.
     But C.I engine generate a Heterogeneous mixture🙂
       2)S.I engine work on  sM.P.F.I system
           But C.I engine work on C.R.D.I system🙂
       3) S.I engine have plastic based common rail because fuel tempareture is cool
        But C.I engine have a metal based common rail is used because Diesel fuel is pressurised and high temparetured🙂know more about what is si and ci engine?

       4)S.I engine use in spark plug
          Where C.I engine use in Glow/ Heater plug🙂
      5)S.I engine have a Ignitor
         Where C.I engine have a Injector🙂

Best way to fix SVN error "Could not start external diff program"

-
Image
One day you found that the SVN Diff function didn't work, you will see the error "Could not start external diff program" when you try to compare 2 versions of the file (the working item vs the one on repository). This could happen on both Windows and Linux, Mac OS... Don't worry, it's not caused by OS but sometimes due to the update of the diff tool (e.g Beyond Compare 3 is updated to Beyond Compare 4), this makes the link to external diff program in SVN settings not valid anymore. So how to fix this error? Just follow the steps below: 1. Right-click a SVN file (it can be any file with SVN version mark) 2. Select TortoiseSVN -> Settings -> Diff Viewer 3. There are 2 options here: 3.1 You can choose the "TortoiseMerge" to use the SVN default diff tool 3.2 or choose your preferred program by clicking "External" -> Enter path to external diff program 4. Click OK to save all your configuration Now enjoy the convenience of diff fe

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

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-side c

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
