On inline engines, a single camshaft controls both the intake and outtake valves. On V-shaped engines, two separate camshafts are used. One controls the valves on one side of the V and the other controls the valves on the opposite side. Some V-shaped engines (like the one in our illustration) will even have two camshafts per cylinder bank. One camshaft controls one side of valves, and the other camshaft controls the other side.

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 engine is undergoing a significant evolution of its own, as new fuel economy and emissions standards in the light-duty and heavy-duty sectors push the development of new technologies on an unprecedented scale toward the theoretical limits of engine operation. Coupled with continuing research into fundamental engine processes, the introduction of affordable high-performance computing, and the adoption of advanced manufacturing techniques throughout industry, those new technologies are leading to potentially disruptive opportunities for the introduction of engines with extraordinarily high efficiencies. How these new engines perform and how they will be integrated into new vehicle architectures will be the story of personal mobility for this half of the 21st century.

Just as electrified cars — whether hybrids or pure battery-powered models — seem headed for market dominance, Mazda announced a breakthrough in gasoline engines that could make them far more efficient. It is the latest plot twist in a century of improvements for internal combustion engines, a power source pronounced dead many times that has persisted nevertheless. Here is some truth-squadding on the latest in auto technology.

Note: The ends of the individual wires should be clean, straight, and undamaged. Their insulation should be stripped 1/2 to 3/4 inch from the ends. Trim any damaged wires and/or strip insulation as needed, using wire strippers.

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.

When fuel ignites in the combustion chamber, the force pushes the piston downward, which in turn moves the crankshaft (see below). The piston attaches to the crankshaft via a connecting rod, aka the con rod. It connects to the connecting rod via a piston pin, and the connecting rod connects to the crankshaft via a connecting rod bearing.

Most states have a 100 amp minimum requirement. Homes running under that service could consider an upgrade to bring them to between 100 and 200 amps, which could run upwards of $2,000. Homeowners should evaluate their power demands first. “A homeowner can have an electrician test the system with an amp meter while all the big loads are on,” says Holt. “If the draw is over 75-80 percent of the service size, you might consider an upgrade. Otherwise you should be fine.”
