Race Porsche

By Mike Trudel

 If your fingers itch for a touch screen even during the morning commute, there may be a solution — particularly when you’re carpooling in the passenger seat and have a minute to play. Vehicles are now being released with “carputers” or “carPCs” as an option, not just as a retrofit. A familiar type of “carPC” to most folks is a Global Positioning System (GPS). According to an online encyclopedia, a GPS device is much like a limited laptop running GPS software.

Basic Specs and Tech:

“Carputer” machines consist of a motherboard, processor and memory and data storage method, such as a hard drive or solid state flash memory. Interface hardware depends on non-distracting options to interact with the “carPC,” such as wireless protocols, which are commonly used to connect to GPS devices and mobile phones. Wirelessly connecting and transferring data to and from home computers is also possible.

A well-executed interface is paramount to the machine’s success, and its software runs the computer’s hardware. Good programming allows drivers to use their favorite piece of technology without being distracted. Common operating systems are available and nearly all are customizable.

Making sure “carPCs” keep their juices flowing is a slightly more complicated matter than it is for the average desktop or laptop. The danger lies in the sudden power drain to certain systems that occurs upon start-up or, of course, when the ignition is cut. To suddenly seize a computer’s supply, however, is risky; software can malfunction and data can be lost. To safeguard against this, a DC-DC power supply is often used, which provides a continuous, 12V power stream to the “carputer.” A DC-AC inverter can also be installed, but it tends to use more energy and produce more wasted heat. The right hardware and software combination allows the computer to sense when the main power source has been cut and use what’s left to safely shut down the machine.

Experiments have found that Internet users experience marked levels of frustration when a Web site takes thirty or more seconds to load. Bearing this in mind, imagine how quickly “carputer” popularity would decline without the relay circuits enabling the machine’s devices to start automatically. Without properly relaying circuits, devices such as amplifiers and screens would have to be started manually — something a portion of the general public doesn’t even know how to do anymore.

Before 2000, LCD character displays were the screen of choice for “carPC” builders. Commands were usually sent to the machine through a keyboard with this system. Soon, wireless serial port remotes were made possible, and small television screens became affordable. The majority of first screens were video input only. For over a grand a pop, though, these were hard to justify. Rapidly advancing technology and production increases have recently made touch screens available and affordable.

Lest one thinks these little “carputers” are all business, entertainment features have been added. “CarPCs” now bring nearly all the entertainment comforts of home onto that cross-country trek. Passengers feel like watching a movie? No problem. Playing a video game? Hook ‘er up. Download favorite music, tune in to satellite radio and map the next trip to Europe on advanced GPS software. It’s all there. No more “Maaa-om. Are we there yet?” “Pop in a movie,” says Maaa-om. Or, “do your homework,” which she downloaded from a desktop at home. At last — technology not only brings hope for peace and quiet but also a way to make sure no one gets too lost along the way.

The possibilities are nearly endless. After all, automobiles have already been introduced to the world of high technology. Consider infrared cameras, a variety of hands-free applications, cargo detectors, lane departure and side (blind spot) warning software — these technological offerings are all not only possible but are already being incorporated. Imagine the capabilities modern computers possess. Now imagine that in your car.

Automotive Telematics Deliver A Brave New Ride
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.

Handling Soot in Antique Car Engines
By Peter Salmonford

 

In the course of running soot is formed in the engine, the quantity varying with the richness of the mixture and the facility for the lubricating oil to get past the piston. This carbonaceous deposit, combined with the non-inflammable constituents of road dust which are sucked through the carburetter, adheres to the cylinder walls and combustion head, causing falling off of power, and in time preignition. When the valve cap is removed it will be found that its underside is coated with soot, and sometimes even with a hard deposit, an indication of the state of the interior of the cylinder. To remove this carbon deposit, the usual procedure is to take off the cylinder so as to expose the parts and scratch off the deposit with a screwdriver or some similar instrument. From the tops of the piston the deposit can be cut away with a knife, and when removed the surfaces should be polished with fine emery cloth, as deposit adheres less easily to a polished surface. The deposit must be completely removed from all parts of the cylinder as well as the piston, a matter of some difficulty.

There have been one or two inventions evolved from time to time to remove the deposit without necessitating the dismantling of the engine. One of these is to insert a steel ball of about 5 inch diameter into the cylinder and then to run the engine, its action being to hammer the carbon deposit and so chip it off the surface. Another, and more promising, process consists in passing a stream of oxygen into the cylinder, lighting it, and so causing a chemical combination to take place between the carbon and the oxygen. As soon as all the carbon has combined the flame goes out, and it is known that the cylinder is clean. The writer has not tried either of these schemes, but mentions them as matters of interest. The ball process, however, would seem rather risky.

To keep an engine in good running order the valves, apart from grinding-in, require careful attention. In the olden days silence of running was not of great importance, but nowadays it is an essential, and to obtain it one of the most important points is to see that the clearance between the valve tappet  and the bottom of the valve stem is small. As the engine runs it will be understood that the tappet  rises rapidly and strikes the foot of the valve. If there is a large clearance between these two the impact between the tappet and the valve causes a clicking noise, which should be stopped by adjusting the tappet head close up to the valve stem. The usual distance or clearance is about 5 inches. The top of the tappet head is inlaid with fibre to reduce the noise, and in course of time this fibre becomes dented or recessed. The tappet should then be removed and its head filed flush so as to remove the indentation.
