Next Generation 2-Stroke Engine

Developed by Orbital leading international developer of engine technologies direct in cylinder fuel injection & lean bum system for enhanced fuel economy & lower emission. This technology exceeds the EP A 2006 emission standards & offers 40% fuel efficiency over conventional two stroke. Different automotive companies have licensed & experimented with Orbital clean burning two-stroke engine & auto major like Peugot, Aprila & other are directly installing these on their new models. It may not take long before this technology reaches India as Bajaj auto already has a tie-up with Orbital.......>>>>Read More


Microturbines operate on the same thermodynamic cycle, known as the Brayton cycle, as larger gas turbines. In this cycle, atmospheric air is compressed, heated, and then expanded, with the excess power produced by the expander (also called the turbine) over that consumed by the compressor used for power generation. The power produced by an expansion turbine and consumed by a compressor is proportional to the absolute temperature of the gas passing through those devices.....................>>>>Read More

Emulsified Ethanol

Ethanol , an alcohol seems to be a most promising option for countries like India because of its availability from agriculture products. Alcohol can be used in diesel engines in following ways. One method is injection of ethanol with inlet air using carburetion or electronic injection system and other is emulsion of diesel and ethanol . And also enable a reduction in exhaust NO X , smoke and particulate matter . .................>>>>Read More

Direct Injection Diesel Engine

The physical and combustion properties of vegetable oils are close to petro-diesel fuel and in this context, vegetable oils can stand as an immediate candidate substitute for stored fuels. Vegetable oils are produced from processing of seeds of various plants and thus Renewable in nature. However due to inherent high viscosity and low volatility vegetable oils would pose problems such as fuel flow and poor atomization and constraining their direct use in engines without any modifications..................>>>>Read More

Running gearing

The running gearing is made up of toothed gear 1 seated on the engine shaft and being in constant mesh with gear frame 2. Gear frame 2 is shaped consisting of two racks of equal length and two toothed semicircles of equal radii. By this alternative the gear frame is connected to piston 3 of cylinder block 5 via a motion unit of Z axis.................>>>>Read More

Fuel Energizer

Generally fuels for internal combustion engine is compound of molecules. Each molecule consists of a number of atoms made up of number of nucleus and electrons, which orbit their nucleus. Magnetic movements already exist in their molecules and they therefore already have positive and negative electrical charges. However these molecules have not been realigned, the fuel is not actively inter locked with oxygen during combustion, the fuel molecule or hydrocarbon chains must be ionized and realigned. The ionization and realignment is achieved through the application of magnetic field created by 'Fuel Energizer'..>>>>Read More

GPS And Applications

The Global Positioning System, usually called GPS (the US military refers to it as NAVSTAR), is an intermediate circular orbit (ICO) satellite navigation system used for determining one's precise location and providing a highly accurate time reference almost anywhere on Earth or in Earth orbit.The first of 24 satellites that form the current GPS constellation (Block II) was placed into orbit on February 14, 1989. The 50th GPS satellite since the beginning in 1978 was launched March 21, 2004 aboard a Delta II rocket......>>>>Read More

Selective Laser Sintering

Rapid Prototyping (RP) can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data. What is commonly considered to be the first RP technique, selective laser sintering was patented by CARL DECKARD A UNIVERSITY OF TEXAS GRADUATE STUDENT. The company was founded in 1989, and since then, a number of different RP techniques have become available. Rapid Prototyping has also been referred to as solid free-form manufacturing; .......>>>> Read More

Agile Manufacturing

The industrial revolution led to mass production practices and the scientific definition of cost accounting system. That period represented seller's market, where demand was greater than capacity. Price was based on the cost of production and expected profit. The fixed of capital was amortized for a long period of time, but variable costs were high and needed to be managed. The solution was simple -treat manufacturing as a cost driver by focusing on local optimization, breaking down to tasks into small simple steps and producing high volumes of standard products at the lowest possible cost. Consequently labor was de-skilled.......................>>>>Read More


Cryogens are effective thermal storage media which, when used for automotive purposes, offer significant advantages over current and proposed electrochemical battery technologies, both in performance and economy. An automotive propulsion concept is presented which utilizes liquid nitrogen as the working fluid for an open Rankine cycle. The principle of operation is like that of a steam engine, except there is no combustion involved. Liquid nitrogen is pressurized and then vaporized in a heat exchanger by the ambient temperature of the surrounding air. The resulting high - pressure nitrogen gas is fed to the engine converting pressure into mechanical power. The only exhaust is nitrogen.....>>>>Read More

Cylinder Deactivation

By considering Daimler Chrysler's new 300cc car's powered by a revival of one of the greatest muscle car engine of all time, the V8 Hemi. This third generation grand master of funk has a capacity of 5.7litres snorts out 340 bhp with 54kgm torque and like all Hemis since the early 1950's has a pushrod valve train rather than a over head cam setup. But even though this Hemi can match its forebears on power 'its thirst for fuel has been cut by 10 to 20%. It is done by Chrysler's new multi displacement system (mds).........>>>>Read More

Personal Protection

It may be necessary therefore, to protect the eye protection equipment. In other instances, it is practically impossible to devise a safe working procedure that can assure there will be no chance of avoidable injury. For example, in construction work there is the possibility of a hand tool, rivet or similarly relatively heavy object's falling from an elevated level and striking the head of a person working below. It is necessary, therefore, that construction workers wear protective headgear....................>>>>Read More

Mine Detection Using Radar Bullets

Now a day in places like Afghanistan and Iraq we know that land mines are causing serious threat to the lives of civilians. The mines that are implanted during the wartime may remain undetected for several decades and may suddenly be activated after that. Also during wartime mines implanted by our enemy countries are to be detected and diffused properly in order to save the lives of our soldiers. So we should say that detecting landmines..... >>>>Read More

Overall Equipment Effectiveness

There are several ways you can optimize your processes to improve profitability. But it can be difficult to understand the overall effectiveness of a complex operation so you can decide where to make improvements. That's especially true when the process involves multiple pieces of equipment that affect each other's effectiveness. One metric that can help you meet this challenge is Overall Equipment Effectiveness, or OEE. OEE measures the health and reliability of a process relative to the desired operating level. It can show you how well you're utilizing resources, including equipment and labor, to satisfy customers by matching product quality and supply requirements..........>>>>Read More
