ABOUT ENGINES

                              SHORT NOTES ABOUT ENGINES

                

                  We all know that all the vehicles are composed of both simple and complex machines which have been discussed in previous post. Now lets discuss about about engines.

                  💨 The engine gives a important contribution in all mechanical works.

                  💨  It is the only one which converts one form of energy to MECHANICAL.

                  💨 Engine blocks are normally cast from either a cast iron or an aluminum alloy. The aluminum block is much lighter in weight, and has better heat transfer to the coolant, but iron blocks retain some advantages and continue to be used by some manufacturers.

💨 To run the engine there are three other strokes are , INTAKE,COMPRESSION, EXHAUST.

💨 To start a engine it must be turned at some speed, so that it sucks fuel and air into cylinders, and compresses it. The powerful motor does the turning. The shaft carries a small pinion which engage with a large gear ring around the rim of the engine flywheel.

COMMONLY ALL VEHICLE RUN IN THE BASIS OF ENGINE :

There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine.

Straight Engine

In a straight engine layout, all the cylinders are linearly arrayed. The engine is positioned parallel to the length of the car, meaning it goes from the front of the engine bay to the back.

Inline Engine

With an inline engine, cylinders are arranged in a straight row, just like a straight engine layout. However, it doesn't go from front to back. Instead, it is perpendicular to the car, meaning it goes from the left of the engine bay to the right.

Flat Engine

As the name suggests, this layout keeps the engine as flat as possible. Sometimes called a 'boxer engine', its cylinders are laid down flat in both directions.

V Engine

Neither flat nor straight, the V engine has its cylinders arranged at an angle in a V-shape. This option is used to combine the benefits of layouts.

CYLINDRICAL ENGINE

Having a different number of cylinders affects the vehicle's power output and fuel efficiency. For car enthusiasts, this also matters because the cylinder configurations also determine what sound a car engine makes.
