VTVT -  Stands for Variable Timing Valve Train, the technology is used in most top variants of the cars. Hyundai has the technology applied to their Hyundai Verna, i20 and i10 models. VTVT has the ability to have independent control of the intake and exhaust valves in an internal combustion engine. The timing of intake and exhaust will be independently programmed in different engine load criteria basically same as VVT. VVT/VTEC -  Variable Valve Timing, term used in petrol, diesel and CNG engines. It defines the timing for which valves are opened. VVT controls the lift, duration or timing of the intake and the exhaust valves. In non-VVT engines, this process of controlling the lift, duration or timing of the intake and the exhaust valves was controlled by a set of cam shafts and belt mechanisms. It would open and close the valves at set angle of the position of the crankshaft and would then close at the same set angle. The engine wouldn’t perform at peak with thi...

TYPES OF FUEL INJECTION SYSTEM CRDe-  CRDe or Common Rail Diesel Engine is another name (by Mahindra) for world-renowned 'Common Rail Direct Fuel Injection' technology. Many car manufacturers in India and world are using this technology with different names. You must have listened CRDI engines in Hyundai cars, TDCi in Ford (Fiesta diesel in India), Dicor (new Safari) in Tata and CDI in Merc ede s. Hence CRDe is not something new, its being used extensively all over the world for a decade now. As we all know diesel is not as good fuel a...

Pulling off the perfect drag strip launch in a manual-transmission car is tricky. You've got to juggle a lot of different variables—your car's traction capabilities, the RPM at which it makes the most power and torque, the conditions of the pavement you're driving on, and on and on.  If you're lighting a tire fire like the driver of that Hellcat shown above, you're probably not putting up your best 0-60 times. And if it's your clutch that's generating the smoke, well, you might wanna steer away from the dragstrip before you need a tow. Delightful YouTube nerd Jason Fenske is here with  another great Engineering Explained video  to help you make sense of it all. Allow him to demystify the many different variables that go into nailing a consistent, reproducible launch to ensure that you're getting the fastest 0-60 and quarter-mile times your car is capable of. Sure, an automatic would make this job easier, but who wants that?

Which is The Maximum Mileage Giving Motorcycle in India? If you are looking for the maximum mileage giving motorcycle, then you are at right place. Bajaj Platina 100cc is the most economical and maximum mileage giving motorcycle in India. May be it is the only motorcycle in the world which has highest mileage. If you are going to buy this one then definitely you are doing the right choice.  Engine type: It is a 4-stroke, natural air cooled type engine.

Th ere are four different methods used    by which Fuel may be ignited ( ignition system ) in  Internal Combustion Engines . If the Ignition in Internal Combustion Engines takes place at the end of Compression Stroke then the engine runs without knocks, with good efficiency. The Compression Ignition Engines are so design that the temperature at the end of the Compression is above the self-Ignition Temperature of Fuel. In this case (ignition system), no spark plug as like in  Spark Ignition  required for Ignition. Different Ignition Methods (ignition system). 01) Hot Tube Ignition Method This is the old method which was used in old days, now this method has become obsolete. But to gain some knowledge, here I disclose some description.This method used in Gas and Light Oil Engines, a porcelain or metal tube closed one end is heated red hot from an external source, to Temperature well above the Ignition Temper...

Internal Combustion Engine Parts And Metals From Which it is manufactured A metal decide the performance and limit of a machine. We are often interested in finding which metal is used in manufacturing of an IC engine and why. In manufacturing of an engine we have to use those metals which can handle the pressure and temperature of the engine and should be cheap in price. Today I am going to tell you about the metals which is used in IC engine and there method of manufacturing. Cylinder block: Cylinder is made by high grade cast iron because it is in direct contact of combustion gases. Cast iron has high compressive strength to handle the pressure and temperature. It is made by casting and usually cast in one piece. Cylinder head: The main function of cylinder head is to seal the cylinder and it should be light in weight. So cylinder head is usually made by cast iron or aluminum. It is made by casting or forging and usually in one piece. Piston: ...

In this article we will take a look on types of chassis and different types of cars in automobile. Have you ever notice that: 1. Why in the collision of a vehicle, like a small car which crushed fully but a truck or big car not crushed fully? 2. Why truck or big cars vibrate greater than a small car? 3. What type of car you have? Types of Chassis You have heard the word "Chassis" many time in automobile but till now you have confusion about it. But Today I am going to tell you about it. Chassis is the base of a vehicle. It consist engine, transmission system, brake system, suspension system, steering system, cooling system, wheels etc.  There are two types of chassis: 1. Conventional chassis or frame-full chassis In this type of chassis the body is made as a separate unit and then joined with ladder frame. It supports all the systems in a vehicle such as the Engine, Transmission system, Steering system, Suspension system.  Advantage Highe...
