Engine 

An Engine is a device which can take up the heat energy convert to mechanical work 🚙 Engine are 2types
I.c ( internal combustion engine)
E.C (External combustion engine)
Internal combustion engine have a two type
  • S.I(Spark ignition engine)
  • C.I(compressed ignition engine)
  • S.i used in petrol engine
  • C.i used in diesel engine

Many more component fitted after create an engine,it is a heart of car, these are produce power for the car run on a path.
Engine components are

Tappet cover is used engine top side it use for cover the camshaft if( over head cam shaft is used)🚙


Camshaft is used for specific timing open and close inlet & exhaust valve,it's have a cam lobe which rolling on engine timing belt🚙

Engine block are used for piston straight way run top dead centre to bottom dead centre smoothly and engine cooling when hot limit cross 🚙

Piston are used for rotating the crankshaft, piston have a many more type,it's combustion chamber are different,it's have A 2 compressin ring and 1 oil scrapper ring and have a journal bearing and small end and big end small end are connected to piston main journal another connect to crankshaft🚙 

Why piston have a 2 compressin ring?Because when piston produce a power stroke these time piston,s have a more pressure while piston don't carry this pressure one ring these  is amain reason piston need A2 compressin ring,if piston have a 1 compression ring those time ring are broken also🚙


Crankshaft have a crank pin crank pin have a specific number which are write on engine block or oil pan
Every two Revolution crankshaft produce a one stroke,four stroke are
  • Suction
  • Compression
  • Power/working
  • Exhaust



Oil pan is used for storing the engine oil,it's have a oil pump which circulate the oil from all over engine interrir
Piston top dead centre(TDC) to bottom dead centre(BDC) continuously run on air fuel ratio🚙
Engine have a(4cyl) 2 inlet and 2 exhaust valve for each cylinder which are installed in cylinder head 🚙


Timing belt are used for air fuel are inject to cylinder timely if car have a belt drive this time timing belt need to replace by specific kilometre may be every 150k (Toyota schedule)if your vehicle have a chain drive this time no need to replace them 🚙

Petrol engine first generate in Otto it's name Otto cycle engine

Another, Diesel engine first produce in Rudlof diesel and irlts called diesel cycle

Other component are describe in below link

[Tutorial] Making a Digital Counter Up 0 to 9 using IC 7490

-
Image
Description counter 0-9 This counter 0-9 in easy to assemble, basic to use for other more complex where we make use of integrated circuits didactically as these could be replaced by other more complex circuits with simple application of microcontrollers. Counter operation 0-9. This counter circuit is formed by a generator essentially comprises a wave 555 which functions as a circuit astable multivibrator operating this type is characterized by an output square waveform with width defined by the designer.The outgoing wave frequency can be controlled by the resistor is connected between pins 7-8 and 2-7 in addition to the electrolytic capacitor connected to pin 2 of land. The pulse output can be varied by 100K ohm potentiometer (RV1). Circuit counter

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...
