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.

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!

It is critical in any wiring project that you match the gauge of the wire with the amperage rating of the circuit. Failing to do so can lead to a fire. A wire's gauge is the physical size of the wire, but the scale is opposite of the wire's circumference. This means that a 2-gauge wire is actually larger than a 14-gauge wire. The size determines how much current can pass through, so the larger wires will be used for your heavier loads.

This type of system is used by a number of suppliers, most commonly in Europe, but hasn't yet come to the market in many areas of the world. Laboe says the amount of increase in fuel economy demonstrated is significant. This technology is coming to meet upcoming regulatory obligations, and Chrysler is interested in this approach because it benefits fuel economy using available energy, and, most importantly, can be incorporated into existing powertrain architectures.

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.

Separate the circuit wires at the existing splice and loosen the cables as needed to make room for the new junction box. Mount the box to the framing (or other support structure) with screws driven through factory-made holes in the back or side of the box, as applicable.

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.
