Capacitor discharge ignition

The necessary high voltage, typically 10,000 volts, is supplied by an induction coil or transformer. The induction coil is a fly-back system, using interruption of electrical primary system current through some type of synchronized interrupter. The interrupter can be either contact points or a power transistor. The problem with this type of ignition is that as RPM increases the available of electrical energy decreases. This is especially as problem since the amount of energy needed to ignite a more dense fuel mixture is higher. The result was often a high rpm misfire.

Capacitor discharge ignition was developed. It produces a rising voltage that is sent to the spark plug. CD system voltages can reach 60,000 volts.19 CD ignitions use step-up transformers. The step-up transformer uses energy stored in a capacitance to generate electric spark. With either system, a mechanical or electrical control system provides a carefully timed high-voltage to the proper cylinder. This spark, via the spark plug, ignites the air-fuel mixture in the engine's cylinders.

While gasoline internal combustion engines are much easier to start in cold weather than diesel engines, they can still have cold weather starting problems under extreme conditions. For years the solution was to park the car in heated areas. In some parts of the world the oil was actually drained and heated over night and returned to the engine for cold starts. In the early 1950s the gasoline Gasifier unit was developed, where, on cold weather starts, raw gasoline was diverted to the unit where part of the fuel was burned causing the other part to become a hot vapor sent directly to the intake valve manifold. This unit was quite popular until electric engine block heaters became standard on gasoline engines sold in cold climates.20

Test drive a luxury car brand

The opportunity to test the car before buying enjoys considerable popularity among customers as well as all other interested parties. Test drive the opportunity to try a bit of luxury as an exclusive brand cars also offer ride exposed for sale cars. I must admit that in this case, it is often true fan event for the automotive industry, which for years had dreamed about it, to go for a car ride, which in everyday terms will not be able to afford. It is no wonder that many people going to a car dealership just to try these wonderful, but exorbitantly expensive machinery. Especially in big cities simulating the role of the potential customer it is fairly easy to do and quite common.


The trendiest gadget automotive - navigation

Although the market there are a lot of gadgets, which are available to the driver, most people reaching for automotive technical innovations selects navigation. It is without a doubt the most popular device, which allows for maintaining the route, even without knowing the map. What's more, most of the satellite navigation sets us some runs and we can decide, according to which we will go. Most people reach for this little device, above all, because it allows not to get lost in an unknown area; by navigation you can also quickly reach the destination in many cases. Fashion for having such a gadget automotive lasts for several years and so far, you can expect that these articles will continue to be very readily bought by drivers.
