MG HECTOR !! 5 FACTS YOU MUST KNOW !!

MG Motor recently announced the name of its SUV for the Indian market. Called the MG Hector, the new SUV will be officially released in mid 2019. Prior to its launch, the carmaker has released a teaser video showing minor details about the vehicle, while testing in extreme climate conditions. Here are 5 interesting facts about the MG Hector SUV that you should know.



1. MG: A ‘NEW’ carmaker for India

Operational since 1924 (pre-Independence era), MG a.k.a Morris Garages was founded in the UK (95 years old) and is known for its classic sports cars and cabriolets. MG was acquired by China’s state-owned SAIC Motor Corporation (SAIC, formerly Shanghai Automotive Industry Corporation) in the late 2000s.



According to the British automaker, the name ‘Hector’ takes inspiration from a couple of sources, all with reference to Europe. First off, the Hawker Hector which served as a biplane in the British Royal Army back in the 1930s. Second, Prince Hector of Troy, the warrior who fought valiantly in the Trojan War.

2. Competitive pricing and rivals

MG is targeting 75 per cent localisation with the Hector at launch. It is expected to be priced between Rs 15 lakh to Rs 20 lakh, similar price range as the Jeep Compass. The MG Hector will also go up against the Tata Harrier, Hyundai Tucson and the Mahindra XUV500.


3. Will get both petrol and diesel engines at the time of launch

The MG Hector will be powered by the same Fiat 2.0-litre Multijet diesel engine as the Jeep Compass. There will also be a petrol engine on offer, but MG Motor is yet to reveal any details about it. We believe that it could be a 1.5-litre turbocharged petrol, as seen on the China-spec Baojun 530. While the is there no confirmation regarding the automatic diesel variant, the petrol-powered Hector is expected to get an automatic version in India.

4. More than 45 MG dealerships at the time of launch

At the time of Hector’s launch, MG will have around 45 dealerships up and running across the country and almost as many service centres. Moreover, MG Motor will also set up a brand-owned dealership in Gurugram for those who want a more in-depth understanding of the brand. The carmaker says all MG owners will be part of an exclusive club as well. The carmaker has already announced 4 dealerships for Punjab, in Chandigarh, Jalandhar, Ludhiana and Amritsar.

5. BIGGER THAN TATA HARRIER

Compared to its arch rival – Tata Harrier, the MG Hector is 57mm longer and 54mm taller. While the former measures 4598mm in length and 1706mm in height, the latter is 4655mm long and 1760mm tall. In terms of width, however, the Harrier takes a lead. While the Harrier is 1894mm wide, the Hector measures 1835mm in width.


The launch of the Hector has been confirmed to take place in Mid 2019, which could be in June 2019. MG will have 100 sales and service touchpoints in place by May 2019.

WHAT IS TSI ENGINE ?? CHECK OUT HERE !!

If you have kept up with updates of the automotive industry throughout the past few years, you have probably heard of Volkswagen TSI engines. It is likely you know about TDI Clean Diesel, but you may be wondering about TSI as well. So, what is Volkswagen TSI, exactly? We will discuss TSI in this post.


TSI stands for “Turbo Stratified Injection.”Volkswagen TSI engine uses a combination of turbocharging and direct fuel injection to offer high efficiency. 

With this technology, these engines can be designed smaller, allowing them to achieve high fuel economy. The direct-injection combined with a turbocharger gives high performance. Allowing the smaller engine to provide an incredible amount of horsepower and torque. With smaller designs and incredibly efficient combustion, the TSI engines are able to provide maximum power with minimum fuel consumption. Most Volkswagen models are equipped with TSI engines including the 2016 Jetta, 2016 Golf GTI, 2016 Beetle, and 2016 Tiguan.


ADVANTAGES :

Some advantages of TSI engines:
  1. Better fuel distribution and better fuel charge inside the combustion chamber
  2. During the injection process, the fuel gets evaporated, cooling the cylinder chamber
  3. The cooling effect of the pressurized fuel allows for use of a lower octane fuel leading to cost savings for the end user
  4. Higher compression ratios, which translates into more power
  5. Increased fuel combustion efficiency
  6. Higher power during pick-up of vehicle


DISADVANTAGES :


  1. Huge rise in the number of emitted exhaust particles
  2. More expensive - much higher pressure fuel pumps are required to inject the fuel directly into the cylinder. This requires fuel pressures of up to 200 bar, much greater than a traditional multiport injection setup.

LEARN HOW TO READ WELDING SYMBOLS !!

The ability to read and understand weld symbols is very important in the manufacturing industry. Like other aspects of drafting, there’s a set of symbols for welding to simplify the communication between designer and builder (i.e. the welder).In this article, we will discuss various welding symbols and their meaning.


Let us begin with the constituents of a welding symbol. A typical welding symbol is shown below.



These figures represent the core structure of every drafting specification for a weld to be performed. The welding symbol has an arrow, which points to the location on the drawing where a weld is required. The arrow is attached to a leader line that intersects with a horizontal reference line. Finally, there's a tail at the opposite end of the reference line that forks off in two directions. The tail is optional and needed only for special instructions.

TYPICAL WELDING SYMBOLS AND THEIR MEANING :

1.) The weld symbol may also be placed above the reference line, rather than below it. This placement is important. When the weld symbol hangs below the reference line, it indicates that the weld must be performed on the "arrow side" of the joint. For example, in the figure shown below, a fillet weld is specified on the arrow side. You can see the actual weld in the second depiction.



2.) If the weld symbol appears on top of the reference line, then the weld should be made on the opposite side of the joint where the arrow points.It is represented in the figure below.


3.) If the weld symbol appears on both sides of the reference line, as shown below, it specifies that a weld must be performed on both sides of the joint. This is represented in the figure below.


4.) Each type of weld has its own basic symbol, which is typically placed near the center of the reference line (and above or below it, depending on which side of the joint it's on). The symbol is a small drawing that can usually be interpreted as a simplified cross-section of the weld. In the descriptions below, the symbol is shown in both its arrow-side and other-side positions.



5.) A weld symbol may also specify an angle, root opening or root face dimension. This is common when the base metal to be welded on is thicker than 1/4 inch. The following example is a symbol and drawing calling for a V-groove joint:



6.) Sometimes, a series of separate welds is specified, rather than a single long weld. This is common when thin or heat-sensitive metals are welded on, or where the joint is a really long one. In the following symbol and drawing, 3-inch intermittent fillet welds are specified and shown in figure below.


7.) Numbers are also a big part of a welding specification. The width, depth, root opening and length of a weld, as well as the angle of any beveling required on the base metal before welding can all be communicated above or below the reference line.

In most cases, the weld width (or diameter) is located to the left of the weld symbol (expressed here in inches), while its length is written to the right. (The weld's width is the distance from one leg of the weld to the other.) Often, no length is indicated, which means the weld should be laid down from the beginning to the end of the joint, or where there's an abrupt change in the joint on the base metal.


Dimensions written below the reference line, of course, apply to the joint on the arrow side, while dimensions written above apply to the joint on the other side. In the image above, welds are indicated for both sides of the joint.

8.) Optional Tail = Special Instructions

As you just saw in the case of the backing strip, the forked tail of the welding symbol is used to convey details that aren't part of the normal parameters declared on the reference line. For instance, the engineer or designer might want the welder to use specific welding ( for example SMAW), or another welding process. Or there may be other information to convey:


Of course, when no special instructions are needed, the tail is omitted from the welding symbol, leaving just the reference line, arrow and leader line.

Apart from these, there are other symbols but these are some of the mandatory symbols that every welding specification contains.
