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.

Automakers are improving fuel economy by exploiting a new controls approach that uses the waste heat from vehicle engines. Currently, up to 65% of the heat energy produced in internal combustion engines, whether gasoline or diesel, is wasted. Typically, the powertrain or engine dissipates the heat by convection, where it is carried to the cooling circuit or lost out of the tailpipe in exhaust gases.

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".

In 1897, the National Fire Protection Association established the National Electric Code (NEC). The National Fire Protection Association was a group of Insurance companies that were concerned about the potential danger inherent in faulty electrical wiring. They had cause for concern. Early wire was bare or covered with cloth. There was little understanding of the need for insulation.

Among the most common projects is installing an outlet. It's a basic project that almost anyone can do if they take the time to understand the process. You may also want to understand how to wire a split outlet. This actually comes in handy if, for instance, you want to plug a lamp into an outlet and be able to turn it on from a wall switch.

From my position at Oak Ridge National Laboratory, I have been able to see the intersection of knowledge discovery, advanced engine and vehicle technology development, and the use of one-of-a-kind computing resources. Although the public tends to think of automobile and engine research as a purely private-sector concern, my colleagues and I at ORNL are helping to realize the full efficiency potential of internal combustion engines.

"AFCI’s give great fire protection to homes with older wiring,” says Mike Holt, licensed electrician, electrical inspector, instructor, and founder of Mike Holt Enterprises, providers of educational resources to those in the electrical profession and related fields. Currently, the National Electric Code requires AFCI breakers for circuits providing power to bedrooms, living rooms, family rooms, and other common rooms in new construction. The cost for an AFCI breaker varies by manufacturer, but consumers can expect to pay around $30 to $35 apiece.

The crankshaft is what converts the up and down motion of the pistons into a rotational motion that allows the car to move. The crankshaft typically fits lengthwise in the engine block near the bottom. It extends from one end of the engine block to the other. At the front of the end of the engine, the crankshaft connects to rubber belts which connect to the camshaft and delivers power to other parts of the car; at the back end of the engine, the camshaft connects to the drive train, which transfers power to the wheels. At each end of the crankshaft, you’ll find oil seals, or “O-rings,” which prevent oil from leaking out of the engine.

Our cities, towns, states and the entire country are crisis-crossed withpower lines that ³carry´ the electricity. As large generators spin, they produce electricitywith a voltage of about 25,000 volts. A volt is a measurement of electromotive force inelectricity. The electricity first goes to a transformer at the power plant that boosts thevoltage up to 400,000 volts. When electricity travels long distances it is better to have itat higher voltages "more efficiently at high voltages".

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.
