Most of the coding is standard, so with a little study, you'll be able to figure out what you have to work with. Wiring does not come in a variety of colors to make it look good. No, there is a wire color coding system that applies to most wires in your home. Most importantly, you need to know that the black, red, blue, and yellow wires are hot and green is often the ground.

If the box is metal, add a pigtail—a 6-inch length of the same type of ground wire—to the ground wire connection, then connect the loose end of the pigtail to the ground screw on the box. Join the white (neutral) wires together, then join the black (hot) wires together. If there are red (hot) wires, join them together. Confirm that all wires are secure by gently tugging on each wire.

The majority of these in homes are what is known as a 'single-pole switch.' They're just as easy to replace as an outlet. Somewhere in your home, you may come across an odd looking switch that makes you stop and wonder. It's likely that this is a three-way switch. They're a little more complicated and used when multiple switches control a single light.

These labels are also standard and will tell you more information about the makeup of the wire. For instance, the code may tell you whether it's aluminum or copper or whether or not it is heat resistant. As you learn more about wiring, you'll realize just how often you need to know these things.

Internal combustion engine efficiency has historically been limited more by the state of technology than innovation. As an example, the potential of technologies such as gasoline direct injection were known and attempted in production more than 50 years ago, but direct injection has only become widely available in production within the last decade and now makes up approximately 38 percent of new light-duty vehicle sales. Another example is low-temperature combustion modes such as homogeneous charge compression ignition combustion—in which fuel and air are injected during the intake stroke and then compressed until the entire mixture reacts spontaneously—which were demonstrated in a laboratory more than 30 years ago but are still many years away from market introduction.

There are small, rounded indentations cast into the cylinder head in order to create room at the top of the chamber for combustion. A head gasket seals the joint between the cylinder head and cylinder block. Intake and outtake valves, spark plugs, and fuel injectors (these parts are explained later) are also mounted to the cylinder head.

Automakers can improve fuel economy by selecting optimal coolant-circuit architectures, heat exchangers, and flow-control devices. The goal of this work was to warm up the drivetrain oils rapidly and run at a slightly higher temperature without additional hydraulic power. Kevin Laboe, who leads the Powertrain Thermal Management Team at Chrysler's Advanced Powertrain Group, Detroit, MI, and who led the simulation and testing teams, says the challenge was to distribute the heat in the most effective way.
By Morgane Seraphine. Engine Wiring. Published at Thursday, September 28th 2017, 22:07:56 PM. The engine block is the foundation of an engine. Most engine blocks are cast from an aluminum alloy, but iron is still used by some manufacturers. The engine block is also referred to as the cylinder block because of the big hole or tubes called cylinders that are cast into the integrated structure. The cylinder is where the engine’s pistons slide up and down. The more cylinders an engine has the more powerful it is. In addition to the cylinders, other ducts and passageways are built into the block that allow for oil and coolant to flow to different parts of the engine.
