The first stage, which coincides in time with general construction work, includes the installation of fasteners or inserts in structural elements for the subsequent attachment of electrical equipment and structures for the installation of electric wiring. It also includes the installation of conduits for electric wiring in the foundations and floors of buildings or structures and the installation of wall sockets for outlets and switches. In the first stage, the preassembly of electrical equipment and wiring structures, the fabrication of conduit sections, and the board lacing of wires and cables for lighting and other circuits are carried out away from the construction site in specially equipped electrical-installation prefabrication shops.

I don’t plan on becoming a full on grease monkey, but I want to have a basic understanding of how everything in my car actually makes it go. At a minimum, this knowledge will allow me to have a clue about what the mechanic is talking about the next time I take my car in. Plus it seems to me that a man ought to be able to grasp the fundamentals of the technology he uses every day. When it comes to this website, I know about how coding and SEO works; it’s time for me to examine the more concrete things in my world, like what’s under the hood of my car.

The exact method you need to follow is going to depend on whether you have a 3- or 4-prong cord. Also, keep in mind that these large appliances carry heavy voltages, so read up on the safety tips. For instance, plugging a loose cord into a receptacle to check the fit can give you a deadly shock. Don't do it!

Even the most efficient and robust engine technologies will never make it to market without the vehicle system meeting emissions regulations. But this is not the first instance where significant emissions control advances were needed to transition a combustion technology to market. Advances in catalyst technologies more than 40 years ago were critical to meeting emerging emissions regulations; the effectiveness of catalysts for conventional spark-ignition engines has since improved by a factor of 100 while achieving a substantial reduction in expensive platinum group metals. Meeting the new challenges is a very active area of research at ORNL and other U.S. Department of Energy national laboratories, as well as in industry.

Game-changing advances in recent years are improvements in engine technologies, sensors, and onboard computing power. This combination of technologies will enable unprecedented control of the combustion process, which in turn will enable real-world implementations of low-temperature combustion and other advanced strategies as well as improved robustness and fuel flexibility. In fact, technological advances are blurring our historical distinction between spark-ignition and compression-ignition engines; we will see new engine concepts that blend the best characteristics of both engine types to push the boundaries of efficiency while meeting stringent emissions regulations worldwide.

On inline engines, a single camshaft controls both the intake and outtake valves. On V-shaped engines, two separate camshafts are used. One controls the valves on one side of the V and the other controls the valves on the opposite side. Some V-shaped engines (like the one in our illustration) will even have two camshafts per cylinder bank. One camshaft controls one side of valves, and the other camshaft controls the other side.

Before you begin your first DIY electrical project, you should learn a little about the wires you'll be working with. Wires vary greatly and each is designed for a purpose. The wiring in your home is chosen to accommodate the load it must carry as well as the conditions it will be exposed to. Some are designed for indoor use while others can be buried. Some are for your panel while others hook up your lights and outlets. It may be confusing at first, but you will probably deal with only a few types of wire in your home.

Copper has always been the first choice because it is such a good conductor and is very flexible. In the 1960 to 1970’s, aluminum wire became popular due to the rising cost of copper. Insulation was usually rubber although rubber tended to corrode due to exposure to moisture and air. PVC compounds are now used most commonly as wire insulation. Insulation is made in different colors to identify wiring circuits in a system.
