ENGINE KNOCKING || CAR KNOCKING



Every diesel car have a injector today's all diesel car have a CRDI (common rail direct ignition)system are fitted,it's totally controlled by a car computer or ECM (Electronic control module) for smooth drive on diesel vehicle this is fitted on a common rail which are adjust the fuel pressure on four cylinder (if 4 cylunder engine)and injector are sprayed as per volume of air on pressing the accelerator 

Fuel supply systems are,

  • Fuel filter
  • Fuel pump(high pressure)
  • Common rail
  • High pressure pipeline
  • Injector

Injector have a different type means injector hole is sprayed on fuel this are some model 4holes some are 6 hole is depended on compression ratio it's have a type name is piezo -electric-type🚙

DIAGNOSIS

Today I will discussed you some problem and solution,how to solve this type of problem easily,small diagnosis but problem is bigger🚙know more about engine knocking
So problem's are as a diesel engine continuously knocking 

HOW TO SOLVE THIS?

We first check visually Injector wiring and if damage so repair first and then start the engine
If Injector wiring are ok while we going on step, car need to a diagnosis tool and check the code and diagnosis as per repair manual wise,first check Injector related fuse, if injector wiring is ok condition,check IDU(injector driver unit) as per manual and next check is IDU to ECM wiring on injector side,injector side

wiring is ok,next ignition on and check all injector coupler voltage if same voltage check diagnosis tool which injector are DTC (Diagnosis trouble code)generate ,and next these injector check the resistance as per repair manual,if not ok change the injector🚙
Normally most of the car cut the any injector wiring on rat bite, but,
I said totally the system,for you diagnosis easily on this situation


This engine knocking or stalling or vibration means "IGNIATION LAG"

Some brand vehicle knocking but it have not a problem on any parts it's knocking because some power source issue and need initializating few minutes and next easy to start

engine knocking mostly on winter because winter season rat are rest in car engine compartment because there have a hot weather so i strongly recommended please clean the engine compartment and check this area daily.

WHAT IS INJECTOR || HOW DOES INJECTOR WORK

CAR INJECTOR AND IGNITOR SPECIFICATION

BELOW WE DISCUSSING CAR INJECTOR AND INJECTOR FULL DETAILS

IGNITOR

Every petrol car have a Ignitor and fuel injector are both in use,
But, every diesel car only injector are used.
Because petrol car used in a air fuel ratio like stoichiometric mixture for smooth combustion this mixture are in the cylinder and spark plug spark instant for smooth combustion

Ignitor are used basically old Distributor these both are same working principle but modify and simple type because old Distributor are more complex

Ignitor working principle is low voltage convert to high voltage, Ignitor have a two coil primary and secondary primary coil have a low coil  and secondary have a more coil this reason when primary coil enter a low voltage and it's continuously flux generate and this reason while secondary coil have a more coil so it's generate a high voltage for sparking in car engine cylinder  because spark plug usually require voltage of 12,000-25,000volts or more to "🔥" properly although it can go up to 45,000 volts
4 cylinder engine have a 4 Ignitor,how many piece Ignitor need it's totally depended on how many cylinder in a car


If any Ignitor fault in car engine engine are stalled and knocking continuously and Engine malfunction on car dashboard cluster metre 

INJECTOR


Every Diesel car have a Injector because diesel car need a compressed air and pressurised fuel, diesel car are not smooth better than petrol car



Old diesel car have a Fuel injection pump for generate pressurised fuel and going through high pressure pipeline to manual injector these time injector just a part of vehicle for fuel spraying and pressure generate are totally depend on (FIP- Fuel injection pump) these time are not fitted in to a any sensor for measure when more fuel press and when less it's totally work on adjusting method🚙

But this time vehicle Technology are totally different and this time vehicle any part problems are solved by measure a standard data means total system are checking in "data Technology" modern car fitted a ECM it is like a "human Head" this ECM are totally control the engine,Modern vehicle have a modern injector this type of injector have a code name means each injector fitted on a specific cylinder because each cylinder injector are this code registered in ECM, because ECM control the firing system
by coding method which time which injector supply the fuel and success combustion this injector have a Nozzle, sim and spring and electrical head which are connected by ECM

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

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-side c
