It works in conjunction with the crankshaft via a timing belt to make sure intake and outtake valves open and close at just the right time for optimal engine performance. The camshaft uses egg-shaped lobes that extend across it to control the timing of the opening and closing of the valves.

Internal combustion engine efficiency has historically been limited more by the state of technology than innovation. As an example, the potential of technologies such as gasoline direct injection were known and attempted in production more than 50 years ago, but direct injection has only become widely available in production within the last decade and now makes up approximately 38 percent of new light-duty vehicle sales. Another example is low-temperature combustion modes such as homogeneous charge compression ignition combustion—in which fuel and air are injected during the intake stroke and then compressed until the entire mixture reacts spontaneously—which were demonstrated in a laboratory more than 30 years ago but are still many years away from market introduction.

The group found that using the waste heat with optimal controls consistently delivered higher oil temperatures and significantly reduced warm-up times. This translated to fuel economy improvements of almost 4% compared to conventional thermal management strategies. The largest efficiency gains occur while heating oil from a cold start, and approximately half of the improvement comes from the powertrain and transmission sides.

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.

In the second stage, the electrical equipment and the structures for the installation of wiring are transported to the construction site, installed in the planned locations, and assembled. In addition, cables and wires are laid and are connected to the installed electrical equipment. Electrical installation work is completed when the installed equipment is actuated and adjusted. The most complicated work in this respect is the adjustment of relay protection and automatic control systems for electric drives.

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.

Opening the grill shutters or running the electric air fan consumes power. Controlling actuators in concert is a new way of addressing thermal management. While more complex, it enables the system to arrive at a steady temperature quicker and under all operating conditions, which extends the life of each thermal-control actuator, Laboe says.

Before you begin your first DIY electrical project, you should learn a little about the wires you'll be working with. Wires vary greatly and each is designed for a purpose. The wiring in your home is chosen to accommodate the load it must carry as well as the conditions it will be exposed to. Some are designed for indoor use while others can be buried. Some are for your panel while others hook up your lights and outlets. It may be confusing at first, but you will probably deal with only a few types of wire in your home.
