So without further ado, we’ll begin our first class of Gearhead 101 by explaining the ins and outs of the heart of a car: the internal combustion engine. An internal combustion engine is called an “internal combustion engine” because fuel and air combust inside the engine to create the energy to move the pistons, which in turn move the car "we’ll show you how that happens in detail below".

The crankcase is located beneath the cylinder block. The crankcase protects the crankshaft and connecting rods from outside objects. The area at the bottom of a crankcase is called the oil pan and that’s where your engine’s oil is stored. Inside the oil pan, you’ll find an oil pump that pumps oil through a filter, and then that oil is squirted on to the crankshaft, connecting rod bearings, and cylinder walls to provide lubrication to the movement of the piston stroke. The oil eventually drips back down into the oil pan, only to begin the process again

Use a screwdriver and hammer to break out each knockout (metal disc), then twist off the knockout with pliers.

The codes are concerned with proper size of wire and with insulation. Factors that are considered are the expected load, the frequency of modifications, and the nature of the environment where the wire is used. Homes have small loads, infrequent modifications and a very non-corrosive environment. Commercial establishments are usually in the middle. The load demands are sometimes higher, and modifications are not infrequent. The factory or industrial site has a very high demand. Modifications are frequent, and the environment is often highly unstable.

Whenever we flip a switch, plug in an appliance, or adjust a reading light, we interact with the electrical system in a house. A good electrician can make those interactions easier in a hundred little ways, so it's best to communicate your needs early—ideally after the house is framed and before the drywall or insulation goes up. That's when master electrician Allen Gallant, who has wired many This Old House TV projects, takes his customers on a job-site walk-through, showing where he plans to put switches, lights, and receptacles. "I'll even ask them if they're left-handed or right-handed," he says. "It makes a big difference when you're looking for the light switch." It's easy to make changes at this point in the process, but once the walls are closed in, any second thoughts become far more difficult and expensive to implement.

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.

GFCIs are also available as circuit breakers installed in the panel, giving ground fault protection to designated circuits in the home.

A joint team from Chrysler and the Center for Automotive Research at The Ohio State University recently developed a practical approach to maximizing drivetrain efficiency and reducing fuel consumption and carbon dioxide emissions. Together, engineers in industry and research, along with students, determined how to capture and effectively distribute the useful heat energy to the transmission and engine oils from a controls standpoint, requiring additional hardware such as a transmission heat exchanger and associated plumbing, and new software. Higher temperature oil is less viscous, so less torque is required for operation and the transmission and engine can operate at higher mechanical efficiencies.

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.
