Test Circuit

By Mike Trudel

 It’s Saturday, which means you have chores to do. You jump in your minivan and turn the ignition. Without being told, your favorite song is cued, your seat is automatically heated to your preferred temperature, and you are reminded of about how many miles you can drive until you need gas. “Oh,” you think, “I’ll get gas first.” With the touch of a button, your navigation system shows your current location and the price of gas at the five nearest gas stations.

Welcome to the world of telematics and the new wave of automotive in-car technology that’s quickly finding its way into our vehicles.

Telematics is deeply embedded hardware, software and telecommunications systems that provide an increasingly wide range of applications that serve our vehicles. These applications can enable safety, security, monitoring of vehicle health and remote diagnostics services. For the driver and passengers, telematics systems can provide dynamic location-based services such as navigation, traffic information, emergency assistance and a suite of other driver services based on two-way connectivity.

The icing on the cake is the idea of bringing the Internet to your vehicle. Automakers are working with Web companies to devise ways of connecting this technology intelligently, and advertisers are ready to jump on board and make it cost-effective, all to integrate your vehicle into the connected world.

Today’s vehicles are already providing a glimpse of what lies ahead. Many already have their own personal computer, their own cell phone and a display monitor. Add a keyboard or touch pad in-dash and the possibilities are endless. It all depends on how much information about yourself you are willing to provide. Data such as your blood type, favorite restaurants and even the stocks you own can prove useful. Ultimately, you will be able to tell your vehicle what you want it to do and when. Want an alert sent to your cell phone if your vehicle alarm goes off? Want to let your significant other know if your airbag has been deployed? Want to know when you’re driving by your favorite coffee shop? Easy to do; your vehicle will be as smart as you let it be.

Global automakers are working toward making telematics the core of the connected vehicle, and they have a strong incentive to integrate this technology as quickly as possible. The competition from connected mobile devices has clearly acted as a very powerful stimulant. Personal Navigation Devices (PNDs) and smart phones are grabbing the consumer’s fancy, and navigation systems are on a lot of wish lists.

PND manufacturers are heavily reliant on sales and are aiming their brand of navigation as a service product. As more devices have navigation capabilities, it won’t be about the hardware but about the service - something that provides two-way communication and lends itself to the consumer’s lifestyle.

Even automakers are realizing that it’s the suite of services that will help them achieve success. The wireless mobile and wireless automotive communities are fighting tooth and nail to win consumers’ hearts and minds.

One industry that is highly interested in telematics is the insurance industry. As more in-car technologies become available, automotive insurers have the opportunity to collect driver data with as much or as little granularity as they desire. They can monitor vehicle location, speed and driving times, or they can collect data on specific, narrowly defined events, such as hard braking. With better underlying data and the accompanying ability to price risk more accurately, insurers can roll out new types of products, often targeted at customers previously considered uninsurable. Information collected in the vehicle can also be used during the claims process. The overwhelming obstacle is the business issue of cost.

This is where advertisers are chomping at the bit to jump on board. Enabling these systems in your vehicle carries a cost, whether it’s a monthly subscription based on usage or a flat fee, and bringing advertisers into your vehicle can lower the cost considerably. So whenever you download a movie into your vehicle for the kids to watch on the next trip, it’s likely to be sponsored by an online movie provider. A major quick lube company will gladly make arrangements for your next scheduled oil change.

Advertisers also see the value of “knowing where you’re going” as a valuable customer relationship management tool. Remember those Saturday chores? Heading to a home improvement store? A telematics- equipped vehicle offers advertisers sophisticated, location-based options never before available. It’s all about capturing a consumer when they’re ready to make a decision. Let your system know you’re going to a home improvement store, and you get a quick glimpse at a discount being offered by one of the major chains. Once your vehicle is detected going to that location, the incentive is activated. You get something in return for sharing your data. Advertisers love that.

Grinding Valves in Antique Cars
By Peter Salmonford

 

Owing to the fact that the inlet valve is not subjected to the temperatures which the exhaust valve reaches, it is very rarely necessary to grind it in. The period at which valve grinding becomes necessary varies with different engines and the care of driving, etc. Roughly, with a water-cooled engine, the exhaust valve should be ground in after 3,000 miles and the inlet after 6,000. No harm can be done by grinding in a valve, so that if an engine loses power before it has run this distance it is well to examine the valves and give them a slight grinding. After the valve is replaced the cotter should be readjusted, and locked by means of the nut.

If a valve is badly burnt examination will show whether it is better to fit a new valve rather than grind in the old one. Very often a badly burnt valve can be recut and trued, and to replace the whole process of valve grinding, a process of valve truing and an apparatus for carrying it out has been evolved by the Southern Automobiles, Ltd. The apparatus consists of a pair of cutters, one of which recuts the valve face after it has been removed, whilst the other has the same effect on the valve seating. Into the respective merits of the two processes it is not proposed to enter, but valve grinding is the more common practice, and it can be applied not only to the main engine valves, but to other valves when the need arises. Thus a petrol or water tap sometimes leaks slightly, when it should be removed and the removable part ground in with some fine emery powder.

It will have been gathered that grinding-in of valves is done to restore loss of compression, but this weakness is sometimes due to other causes. For instance, any one of the cylinder joints may be leaking. The sparking plug washer and that upon the valve cap which screws into the opening sometimes leak, and to ascertain if this is the case some paraffin should be squirted round these washers and the engine turned round just to come on to the compression stroke. When pulled slowly over the compression stroke the presence of bubbles will indicate if there is any leakage at these points. If there is leakage new washers must be used. On no account should any adhesive mixture, such as boiled oil or gold size, be put on the screw threads. This is sometimes done to obtain good compression, but it is inadvisable, on account of the extreme difficulty in separating the parts later.

Drive-In Theaters Or Driving Theaters? Today’s On-Board Vehicle Entertainment
By Mike Trudel

 There was a time when a static-filled sound box and a bag of greasy drive-in popcorn had to suffice for vehicle theater entertainment. Today’s vehicle manufacturers have taken the theater experience of yesteryear and brought it into the 21st century with a virtual in-car entertainment system. Portable device interfaces, media players and satellite television are just a few emerging technologies for an automotive engineer to consider integrating as an attractive magnet for potential car buyers.

Portable Entertainment

Functionality and integration of portable entertainment has become more than just a feature for luxury vehicles. Portable device interfaces allow drivers to access their home music library or a video game via their automotive system using a USB port. MP3 players connect directly to a vehicle radio and allow control of music selection while song title, artist, album and elapsed time are conveniently displayed on the radio. SD Card Playback, a navigation database interface, can also be used to bring music into the vehicle.

That’s Infotainment

With the advent of media players, today’s driver can integrate a variety of entertainment and information content to his or her preference. Music from multiple sources can be searched and played using a single interface. And those interfaces are controlled via voice, soft keys, a central control knob or steering wheel controls. Want to hear only reggae or pop while driving home from work? A “Similar Songs” button looks into the database and selects similar songs for play. Other media player features include Bluetooth (R) audio streaming, DVD-V/ROM, MP3 and full-featured navigation capabilities.

Best Seat Isn’t Even in the House

“Are we almost there?” is likely to turn into “We’re here already?” for those who discover the best seat in the house is at the rear of a vehicle. Rear-seat entertainment allows passengers to enjoy movies, music and video games via an LCD color monitor, which offers a crisp and clear picture, even at extreme viewing angles. Factory-installed systems include a DVD player, which forms the core of the system and can also read music, data files and photos. Illuminated keys let the viewer keep control of the DVD player, even in the dark.

After short journey breaks or after the engine has been switched off, a special module enables the system to know exactly which content was played last - so users do not have to go searching through the last film or music program.

Soon, consumers may also begin to see video/wireless systems that deliver separate options for the driver, front-seat passengers and the rear-seat positions. Drivers might listen to satellite radio, while passengers separately employ headphones to listen to MP3 players or watch DVDs.

TV on the Open Road

Satellite television allows passengers to leave DVDs at home and instead enjoy digital-quality entertainment channels on the open road. Various systems can provide access to more than 100 programming channels and more than 50 channels of satellite music. In addition, families can catch the big game, traffic reports or local news stories from the comfort of their vehicle via local networks. Satellite TV also integrates with various in-vehicle backseat video systems.

Popcorn Optional

Today’s on board car entertainment system provides seamless experiences in music, movies, television and more. Greater freedom from home to the open road means access to entertainment, navigation and safety features from behind the wheel. With all of these options, drivers may discover the best seat in the house is actually parked out in the garage.
