Before 1970 the evolution of engine design was driven by a quest for performance and an increase in octane in the fuel supply. Since then, however, the imperative was the need to meet new emissions and fuel economy regulations.

Building on that work, in 1864 two German engineers named Nicolaus August Otto and Eugen Langen founded a company that made engines similar to Lenoir’s model. Otto gave up managing the company and started working on an engine design that he had been toying with since 1861. His design led to what we now know as the four-stroke engine, and the basic design is still used in cars today.

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.

Many low-temperature combustion modes such as GCI and RCCI operate on the edge of stability—in other words, at conditions under which very small variations in engine boundary conditions (such as intake temperature) may result in unintended excursions that result in undesirable emissions, reduced efficiency, and the potential to destroy the engine or emissions control system. One can imagine the challenge of these types of combustion modes under ever-changing conditions of a real-world drive cycle where a single unintended excursion could be catastrophic. Meeting that challenge requires a control system which is predictive for avoidance rather than reactive after the occurrence of a potentially damaging event.

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.

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.

The push toward higher-efficiency engines will alter exhaust temperatures and chemistry and may create challenges for emission control technologies. For example, new higher-efficiency engines will have lower exhaust temperatures, due to more efficient work extraction at the piston. Lower exhaust temperatures will, in turn, require the development of new emission control technologies, which must not only be effective at low temperatures but also must survive high exhaust temperatures encountered under high load conditions.
