THE CHASSIS

There is usually a thick wire coming from the other, hot, end of the power source (battery, or ac socket, or other power supply), and this main wire is called the bus. (In England it is often called the rail. ) In Fig. 6.3, it is shown as being a positive-charged dc bus, and various components (the 330 and the 2.2K) get their electric power from this wire.

The chassis moves on low-friction rolling mounts or guide rails (Figures 13.2 and 13.36). 

For withdrawable parts, such as a draw-out breaker or a draw-out chassis, proper movement of the movable parts and making of the contacts should be ensured. To verify this requirement, the chassis may be moved in and out for at least 50 times. 

Using a rear-wheel-drive vehicle as an example, a prop shaft delivers power from the transmission output, near the middle of the vehicle, to the differential that drives the wheels at the rear. If this prop shaft is designed to be stiff, which is normally the case, it could not be rigidly attached to the transmission output at one end and the differential at the other because of the differences in vertical movement between the drive wheels and the chassis. Typically, two universal joints are inserted into the drivetrain to accommodate this situation. 

The chassis is made from a 1/4 in. sheet of either ABS or TPO vacuum formed into a tub and reinforced with reinforced pultruded glass fiber-TS polyester plastic tubing. The hood and other products are being made from a 20 mm thick sandwich of thermo-formed PPO-alloy skins, glass fabric infused with thermosetting vinyl ester, and a urethane foam core. The bumper and front fascia is thermoformed from a polyolefin elastomer sheet with an UV-resistant cap layer of DuPont s Tediar PVF film. The dash and... 

Quadraxially oriented (four directional layer) glass fabric-TS vinyl ester polyester RP sheet panels with a foam core and gel coating are used. Most of the panels are 3 mm thick with molded-in rib structure supports. Body skins are bonded to the chassis with a double-stick acrylic tape developed by 3M Co. as well as mechanical fasteners. Unlike most steel designs, no B-pillar structural component between the front and rear doors is required thus providing more interior space and easy entry since doors open in opposite directions. 

Example Suppose we measure 2pA going from right to left in one wire. And we measure 5p A going from left to right in the other wire. We don t know the current through the chassis ground (earth). What are the CM and DM components involved ... 

That would have brought the Drain end of the Primary winding right next to the safety barrier, with the Secondary ground end (which is usually connected to the chassis) directly across the isolation boundary. With this winding arrangement, we would have a healthy dose of CM noise injected directly into the chassis/earth. 

The reed sensor is usually mounted in the chassis of the appliance and the permanent magnet is placed in the doorframe. Thus, when the door is closed, the magnets position is above or parallel to the sensor. When someone opens the door, the circuit is broken. 

Toyota and Honda have been experimenting with both methanol and metal-hydride storage of hydrogen. Honda has built several test cars, in 1999 a Honda FCX-V1 (metal-hydride hydrogen) and FCX-V2 (methanol) were tested at a track in Japan. The Ballard powered version-1 was ready, but proved to be a little sluggish and noisy. The other car suffered from a noisy fuel cell. Both Honda fuel cell test cars were built on the chassis of the discontinued EV Plus battery electric. Honda used a different and more aerodynamic body. 

The Sunmobile is charged solely with photovoltaic panels mounted as a roof canopy. It will travel at up to 30 mph with a range of up to 30 miles on a fully charged battery. A twist grip on the handlebars feeds information to a motor controller mounted under the chassis. 

Under the chassis suspension parts, belly pans, plugs, bumpers, grommets. .. 

When the ignition switch is on, a relay turns the inverter on, the relay lead contains a 20 amp in-line fuse. This relay only turns the inverter on and off and has no other function. The inverter is connected to the battery via a positive wire and a negative wire (not the chassis). The inverter is not grounded to the car at any point and instead, is carefully insulated to ensure that accidental grounding never occurs.

Capacitance, stray— is the undesired and unintentional capacitance parts of an experimental setup or instrument, as, e.g., an electrical conducting wire and the chassis. 

Over the past decade, automotive supplier parks have proliferated in South America and Europe as automakers pursue a manufacturing value chain that is as lean and efficient as possible. That trend has recently aslo gained popularity in North America. Ford Motor Company launched its first North American supplier park in Chicago in 2004, where painted exterior and interior components will be produced. Chrysler is planning a supplier co-location project at the Jeep Toledo North Assembly plant, where painted vehicle body and the chassis module will be sent on conveyer lines directly into the Chrysler Group s final assembly building. 

Figure 1 Coexistence of the past and present techniques in F F industry classical enfleurage process (photo on the left) and a supercritical carbon dioxide extraction facility as modern factory equipment (on the right). The photo on the left shows a stock of jasmine flowers in the basket (center) that are spread upon a wooden frame (chassis) that secures a glass plate coated with fat. The chassis is then piled to allow diffusion of fragrant components (note that the fat is applied on both sides of the glass plate to gain access to the headspace volume made by the chassis underneath).

Phase I—Chassis Dynamometer Tests. A 1.3-L engine equipped with a four-speed automatic transmission and complete drive system was calibrated to meet 1974 emissions standards using Indolene reference fuel. This standardized apparatus was then used in conjunction with the federal emissions test procedure to evaluate the performance of methanol/gasoline blends. Results of the single cylinder test program and preliminary evaluations with the chassis dynamometer system indicated that blends should be limited to 10% methanol or less to avoid drive-ability and other problems. A complete discussion of the apparatus and test procedures is given in Ref. 9. 

The results of the chassis dynamometer test program are presented in Figures 12 and 13. For the base fuels tested, the most notable change is the decrease in CO emissions. A nominal reduction of 30% is obtained by adding 10% methanol to the base unleaded gasoline. This reduction has also been noted by Wigg and Lunt (11) and by Brinkman et al. (12). 

Since the substrate volume controls TSA, which, in turn, affects conversion efficiency, its cross-sectional area A should be maximized and its length ( minimized to reduce Ap Of course, such an optimization of substrate shape will depend on space availability under the chassis.
