Difference Between Petrol Engine And Diesel Engine

In my previous written articles i write about most four stroke engine and two stroke engine. In this article i will tell you all about petrol engine and diesel engine . There are so much different between petrol engine and diesel engine as i written below:

Petrol Engine:


  • In petrol engine the mixture of air fuel enter in the cylinder between suction stroke.
  • Corroborator used in petrol engine.
  • The pressure of air fuel mixture at the end of compression stroke may be 10 bar.
  • Spark plug will use in petrol engine for Ignition.
  • The Compression ratio in petrol engine will be 6-10.
  • Petrol Engine are less in weight and cheap in rates.

Diesel Engine:


  • In diesel engine only fuel enter in the cylinder between suction stroke.
  • Fuel Injector will use in diesel engine.
  • The pressure of compressed air at the end of compression stroke may be 35 bar.
  • Compression will use in diesel engine for ignition.
  • The compression ratio in diesel engine will be 15-25.
  • Diesel engine are heavy in weight and expensive in rates.

Use Of Belt Drive in Automotive Engineering

Definition Of Belt Drive In Mechanical Engineering:

Belt is used to transmit power from one shaft to another with the help of pulley. In this cause if pulleys rotate on same speed or different does't matter. There are some reason or some point when belt drive selected.

  • Speed Of  Drive and Driven Shaft 
  • Power want to transmit
  • Distance between Shafts
  • Need of positive drive
  • Required Space
  • Layout of Shaft
  • Service Condition

Types Of Belt Drive:

There are different kind of belts drives that are used in Mechanical Industry and also in automotive Engineering for different kind of work.

1. Light Drive            2. Medium Drives              3. Heavy Drives 

        1.Light Belt Drive:


Light drives always used for less speed and transmit less power from one shaft to another.Belt speed should be 10 meter per second in light drive belt.

       2. Medium Belt Drives:


Medium drive is used for transmit medium power from one point to another. The speed of medium belt drive should be more than 10 meter per second and less than 22 meter per second.

       3. Heavy Belt Drives:


Heavy drive is used for transmit large number of power from one point to other. The speed of Heavy belt drive should be more than 22 meter per second.

Different Kinds Of Shaft Use In Mechanical Industry

In my previous written article i was telling you about shaft, axle and spindle and now in this article i will tell you about types of Shaft that are use in mechanical industry and also use for different kind of work.
There are two types of shaft:
  1. Transmission Shaft
  2. Machine Shaft

Transmission Shaft:

Transmission Shaft is used to transmit power to machine from source. Counter Shaft,Line Shaft, Over head shaft and all kind of factory shafts are types of Transmission shaft.That's why transmission shaft has bending moment also with twisting moment.

Machine Shaft:


This kind of Shaft is working as a machine part. In other way this shaft also called a machine part that's why its called machine shaft.Crank Shaft is the very good example of machine shaft.

Use Of Shaft, Axle and Spindle In Automotive Engineering

Axle , Shaft and Spindle are mechanical things that use in mechanical industry and also in different kind of work. All three things has same round type of shape but in function and work all three things are different and important according to the work as i explain below all three one by one.

Shaft:


Shaft is a round moving machine element which use to transfer power from one place to another.The power transfer to shaft through  tangential force. In the result twisting moment or torque built in shaft and Power transfer to other machine part that were join in this shaft.

Axle:


Axle looking like shaft but function of axle is to much different from shaft.Axle is machine element which did not move but its use to transfer bending moment form one machine to another.Axle also give support to the moving machine elements like wheel of car.

Spindle:


Spindle also like a shaft but its length is bit to short. Spindle is use for giving the motion to cutting tool. Simple example of spindle is drill chuck that's give motion to drill for making hole.
