KNOW WHAT DOES COLOUR CODING ON NUMBER PLATE MEAN !


As per the Motor Vehicles Act of 1988, no vehicle can be driven by any person in public places in India until it is registered by a registering authority. When the registration process of a vehicle is complete, it is assigned a number plate which is known as the official number plate. There are various types of number plates in India.Every number has a different colour coding which signifies a unique meaning.We will understand the meaning of various number plates and their meaning in this article.

A license plate is a combination of alphabets and digits that form a registration number. The license plate is issued by the district RTO (Regional Transport Office) and should be placed in the front and the back of the vehicle with provision for illumination. The international registration code for India is IND.

DECODING A NUMBER PLATE:



VARIOUS COLOUR CODING FOR NUMBER PLATE :

There are various parameters that decide which vehicle bears which coloured number plate.

White number plate with black lettering

Cars bearing black lettering on a white background are private vehicles. These are used solely for private purposes and can't be used for any commercial purpose like goods transport, ferrying passengers etc.


Yellow number plate with black lettering

These are commercial vehicles like taxi, cabs, trucks. Yellow number plates have a different tax structure compared to white number plates and commercial car drivers with yellow plates are also mandated to have a commercial driving permit.



Black number plate with yellow lettering

These are commercial vehicles available on rent for self-drive. These cars can be put to any commercial purpose without the limitation of the driver having to own a commercial driving permit.


Green number plate with white lettering

This number plate is limited to electric cars only. This is applicable to road-legal electric buses and other electric commercial vehicles (like Mahindra e20, Tata Tigor Electric,Tata Nexon EV).


Red number plate with white lettering

The red registration plate is issued as a temporary registration for a brand new vehicle until permanent registration us issued by the RTO. Temporary registration is valid for 1 month only. However, all Indian states do not allow temporarily registered vehicles to ply on road.Also, the vehicle is being used by the President of India or any of the state governors.




Blue number plate with white lettering

A blue coloured number plate with white lettering is issued to a vehicle belonging to a foreign diplomat United Nations (UN), Diplomatic Corps (CD) or Consular Corps (CC).



Number plate with an upward-pointing arrow

Military vehicles follow a unique numbering system unlike any other license plate numbers. The numbers are registered under the Ministry of Defence, New Delhi. The first/third character is an upward-pointing arrow, known as a Broad Arrow, used in many parts of the British Commonwealth. The two digits succeeding the arrow show the year in which the Military procured the vehicle.


Overall, a vehicle plate number has lot of components which are essential for any driving license holder to know.

KNOW WHY GASKET IS USED IN ENGINE !


You might have seen a rubber or strip like structure when you disassemble an engine.This rubber like structure is called gasket.We will know the importance of gaskets in engines in this article.


A head gasket is a mechanical seal that sits between the engine block and cylinder head(s) in an internal combustion engine.Modern vehicles are commonly manufactured with an engine block and a cylinder head bolted on top, which makes a head gasket a critical seal. This important component is situated between the engine block and cylinder head. It is a machined casting for an internal combustion engine, designed with cylindrical bored holes for hosting the pistons. A head gasket performs the task of a seal between the engine block and cylinder head.


The head gasket in modern vehicles is comprised of several layers of steel material entwined with elastomer, making them more durable and longer lasting. Vehicles produced in the past were equipped with gaskets created by graphite or asbestos. In comparison, today’s gaskets are better as they are less prone to leakage and have little to no health risks as opposed to asbestos produced gaskets.



The main functions of head gasket as as follows:


1.)The gasket joins irregular surfaces (we speak in terms of millimeter microns). For this reason, it is necessary to insert 
a softer material, such as a fiber or an elastomer between both surfaces which is able to adapt to those imperfections, which ensuring a perfect sealing.

2.)It maintains the sealing need and prevent leakage between the two crucial engine parts, when being subjected to the compression process.


3.)The gasket performs the task of separating the passage of oil and water that pass through the block and cylinder head of the engine.The head gasket keeps the chambers separated to ensure there is no cross-contamination of fluids.


4.)It prevents dust and dirt from getting into the engine and causing damage.


Various materials can be used in the manufacture of gasket: rubber, silicone, metal, cork, fiber or polymers.On certain occasions it may be found that the compression in the cylinder creates a perforation, or hole in the head gasket; generally known as a blown head gasket.




When the head gasket has blown, it’s critical that it be addressed immediately. Continuing to operate a vehicle with a blown gasket can cause serious and irreparable damage to the engine. When gasket is blown, you may notice a few or all of the following symptoms:


>Overheating – Caused by a lack of or reduced coolant. Also caused by hydrocarbons entering the cooling system.


>White, Blue, or Grey smoke – Indicates coolant or oil has entered the combustion chamber.

>Loss of Power – Due to a lack of compression resulting in sputtering, loss of power, and reduced fuel efficiency.

>Discolored Oil – A chocolate milk-looking oil is indicative of coolant mixing with oil in the engine.


So,next time when you face above problems, do not forget to check your gasket once.Thank you for reading this article.

DIFFERENCE BETWEEN PIPE AND HOSE EXPLAINED !


Transportation of fluids uses different types of tubes, among which most commonly used tubes are hoses and pipes. They are efficient in transferring liquids from one point to the other.We will discuss the difference between hose and pipe in this article.

Pipe

A pipe is a hollow cylinder or tubular section, which is used in conveying substances that flow. They are typically utilized for structural applications, fabrication and railings. Tube and pipes can be interchangeable. However, when it comes to engineering and the industry, these terms have separate definitions. Pipes are usually put up for long-term purposes. The flow of the liquids is supported by tees and elbows.


Hose

A hose is a hollow-shaped tube created to transmit fluids from one point to the next. Hoses are built based on application and performance. They are usually designed based on their Pressure rating, weight, length, coil hose, straight hose and chemical compatibility. There are various types of hose based on their applications, such as garden hose, fire hose or air hose. They are usually used with spigots or clamps in order manage water flow.

Difference Between Hose and Pipe:


>A hose is a hollow-shaped tube created to transmit fluids from one area to the next.

>A pipe is a hollow cylinder or tubular section, which is used in conveying substances that flow.

>A hose is smaller than pipe.

>Hose is composed of a more flexible material compared to pipes that are composed of rigid tubes.

>Hoses are a combination of various materials from polyurethane, polyethylene, nylon and natural or synthetic fibers while pipes are made from fiberglass, metals, ceramic, plastic and concrete.

>A hose generally has a circular cross section while pipes may or may not have one.
