Igniting a Spark

Igniting a Spark
Your Volvo has thousands of parts in it. Some play a crucial role in the car, while others do not. Some are used all the time, while some are needed only for a specific time. One of the latter is your Volvo’s ignition coil. Also called a spark coil, the ignition coil is an induction coil in the automobile’s ignition system. The Volvo ignition coil transforms a storage battery’s 12 volts into the thousands (which sometimes could reach as high as 120,000 volts) needed to ignite the spark plugs. Invented by A. Kent Atwater in 1921, the ignition coil is a simple transformer that has two sides: the 12 volt or primary side and the high voltage or secondary side. The primary side contains a few hundred turns of a large diameter wire and it builds up the magnetic field in the coils. On the other hand, the high voltage side contains thousands of turns of small diameter wire. The coil uses electromagnetic induction to create the high voltage. When the voltage in the primary side is turned off, the collapsing magnetic field in the secondary side induces a voltage in the secondary side, producing thousands of volts. In older vehicles, a single, large ignition coil would serve all the spark plugs, distributing voltage via an ignition distributor. In modern systems, the distributor is omitted and ignition is controlled electronically, instead. Much smaller coils are used with one coil for each spark plug or one coil serving two spark plugs (so two coils in a four-cylinder car). These coils may be remote-mounted or they may be placed on top of the spark plug (coil-on-plug or direct injection). Where one coil serves two spark plugs (in two cylinders), it is through the “wasted spark” system. In this arrangement, the coil generates two sparks per cycle to both the cylinders. The fuel in the cylinder that is nearing the end of its compression stroke is ignited, whereas, the spark in its companion nearing the end of its exhaust stroke has no effect. The wasted spark system is more reliable than a single coil system with a distributor and cheaper than coil-on-plug. Where the coils are remote mounted, they may all be contained in a single molded block with multiple high-tension terminals. This is commonly called a coil-pack. Your Volvo ignition coils are part of a larger system, which is the ignition system. The ignition system is part of an even larger engine system. The ignition system’s primary responsibility is the timely burning of the fuel-air mixture in the engine. Your Volvo user’s manual would carry the recommended service interval for your ignition system, including your Volvo ignition coil. Your Volvo engine might run rough, buck, surge, stall or even get poor fuel economy. These are signs that your ignition system might need servicing as they are potentially an ignition system problem. When this happens, drive to the nearest Volvo dealership and have a qualified technician take a look around. Your Volvo engine might be in problem in the long run.

How Cost Effective Are Hybrid Cars?
There seems to be no stopping the oil companies, as the price at the pumps continues to rise to astronomical heights for a myriad of reasons, valid or not. Civil wars in Nigeria, international conflicts in Iraq, hurricanes and other storms at home and abroad are all reasons gas companies posit to defend their outrageous gouging. In the face of rising gas costs, many consumers are beginning to consider the option of a hybrid vehicle- one which operates on both gas and electricity. All of the models of hybrid car will save money in terms of gas expenditures, but are they really effective when all of the costs of maintenance and other considerations are factored in? Right off the bat, consider the cost of buying a hybrid vehicle. Depending on the model, hybrid vehicles can cost anywhere from $2,000 to $5,000 more than the equivalent non-hybrid model. These prices need to be stacked up against the savings that a hybrid car owner would gain in gas, factoring in the mileage needed. One report by Edmunds, for example, shows that huge price increases in the cost of gas would need to take place, or the vehicle owner would need to put on some serious mileage, in order for the hybrid models to gain a sufficient price saving advantage when stacked up against initial purchases. The one exception in the study was the Toyota Prius, which compared very effectively in terms of initial cost with the Camry model. The consumer watchdog points out, however, that as the hybrid cars become increasingly more available as a reflection of demand the prices can be expected to drop, making them more cost effective when it comes to an initial investment. Also important to keep in mind is the fact that the hybrid cars have a much more specialized system than the standard vehicle, and will therefore require a more specialized mechanic when it comes time for any repairs. Most consumer report features consider hybrid cars to require an investment of at least five years in order to break even as far as initial costs go, and do not take into account the possibilities of damage that requires fixing to the power train of the vehicles. It seems as though, at least for the time being, the purchase of a hybrid vehicle for the average consumer may not be the best option when it comes to saving money. It is important to keep several things in mind, however, when considering purchasing a hybrid model. Many consumers are choosing to purchase these cars because they represent a significant development in terms of environmental concerns over standard models. They also mean that as a whole, Western nations will become less dependent on oil as the sole means of power. Finally, it is imperative to keep in mind that the hybrid car is a very new technology. Developed only within the last few years, the technology is still in the infant stages, where costs will continue to be high. Hybrid cars also have only a small percentage of the market right now as well. As time passes, the development of the hybrid technology will begin to push prices down to the point where hybrids are more than competitive with the traditionally fueled models of the past.
