The Relationship Between Pencil Coil and Coil Ignition System

       Known for its incorporate electrical, mechanical and thermal isolation between the magnetic core, which is used for creating magnetic field, the pencil coil is one of the general categories of ignition coil. The engines generally use a mechanically times ignition system, and the key of this system is the distributor. Containing a rotating cam driven, a set of breaker points, a condenser and a distributor cap, the distributor is linked to the spark plugs and ignition coil with wires. And the pencil coil is inserted inside the spark plug insertion hole in the cylinder head.

       Originally, every ignition coil system required mechanical contact breaker points, and a capacitor (condensor). More recent electronic ignition systems use a power transistor to provide pulses to the ignition coil. A modern passenger automobile may use one ignition coil for each engine cylinder (or pair of cylinders), eliminating a distributor to route the high voltage pulses.

       Very early gasoline (petrol) internal combustion engines used a magneto ignition system, since no battery was fitted to the vehicle; magnetoes are still used in piston-engine aircraft. The voltage produced by a magneto is dependent on the speed of the engine, making starting difficult. A battery-operated coil can provide a high-voltage spark even at low speeds, making starting easier. When batteries became common in automobiles for cranking and lighting, the ignition coil system displaced magneto ignition. 

The Different Types of Trailer Hitches

       Trailer hitches are means of connecting a trailer to the rear of your vehicle. With the addition of a hitch, you can expand your vehicle's usefulness by being able to haul items that would normally be too bulky or heavy to place in the vehicle itself. Trailer hitches are made for most vehicles, from large pickup trucks and sport utility vehicles to small four-cylinder economy cars. No matter what size the tow vehicle, using the correct hitch and installing it properly is the key to safe trailer towing.

       If you want to pull a trailer or another car behind your vehicle, you’ll need a hitch. There are five classes of trailer hitches, each with a different weight rating, so you’ll need to have a good idea of what you need your hitch for before you start looking.

1. Class 1 hitches tow up to 2,000 pounds or 907 kilograms; they can be used to pull a trailer that is six feet or 1.8 meters long, or a boat that is 14 feet or 4.3 meters long. These hitches are good for use on smaller cars, such as small sedans, sports cars, and compact cars.
2. Class 2 hitches tow up to 3,500 pounds or 1,588 kilograms; they can be used to pull a trailerthat is 12 feet or 3.7 meters long, or a boat that is 20 feet or 6 meters long. These hitches work well on larger cars, such as midsize sedans and minivans, but are not suitable for compact cars.
3. Class 3 hitches are more heavy-duty hitches. They come in different sizes, but the largest of them can tow up to 5,000 pounds or 2,268 kilograms. A class 3 hitch can be used to pull a 24-foot or 7-meter boat trailer.
4. Class 4 hitches are also much more heavy-duty hitches, especially because their mounting brackets distribute weight more evenly along the frame of the truck that is doing the towing. Class 4 hitches are designed for use with full-size trucks, and will easily pull 7,500 pounds or 3,402 kilograms.
5. Class 5 hitches are the largest hitches available. Class 5 hitches can pull as much as 14,000 pounds or 6,350 kilograms.  

       In conclusion, choosing a hitch for your car is an important decision. You need to be fully prepared and well educated so as to make the most proper decision. It’s important to know what you will be using the hitch, and how much weight you could possibly be pulling, as well as what kind of vehicle will be doing the pulling.

 

The History of Leaf Spring

       There were a variety of leaf spring types, usually employing the word "elliptical". "Elliptical" or "full elliptical" leaf springs referred to two circular arcs linked at their tips. This was joined to the frame at the top center of the upper arc, the bottom center was joined to the "live" suspension components, such as a solid front axle. Additional suspension components, such as trailing arms, would be needed for this design, but not for "semi-elliptical" leaf springs as used in the Hotchkiss drive. That employed the lower arc, hence its name. "Quarter-elliptic" springs often had the thickest part of the stack of leaves stuck into the rear end of the side pieces of a short ladder frame, with the free end attached to the differential, as in the Austin Seven of the 1920s. As an example of non-elliptic leaf springs, the Ford Model T had multiple leaf springs over its differential that were curved in the shape of a yoke. As a substitute for dampers (shock absorbers), some manufacturers laid non-metallic sheets in between the metal leaves, such as wood.

       Leaf spring was very common on automobiles, right up to the 1970s in Europe and Japan and late 70's in America when the move to front wheel drive, and more sophisticated suspension designs saw automobile manufacturers use coil springs instead. Today leaf springs are still used in heavy commercial vehicles such as vans and trucks, SUVs, and railway carriages. For heavy vehicles, they have the advantage of spreading the load more widely over the vehicle's chassis, whereas coil springs transfer it to a single point. Unlike coil springs, leaf springs also locate the rear axle, eliminating the need for trailing arms and a Panhard rod, thereby saving cost and weight in a simple live axle rear suspension.

       It sometimes referred to as semi-elliptical, cart, or laminated springs. The center of this arc-shaped spring is usually attached to the axle of the vehicle it supports, while the ends of the spring are attached to the frame itself. In some cases, a leaf spring may be attached to the vehicle frame on one end and the other end will be attached to a short swinging arm known as a shackle. This type of spring configuration often helps to provide a softer, less rigid suspension system. Some automobile manufacturers have recently developed a leaf spring that is constructed of a composite material similar to plastic in order to provide a softer type of rear suspension.
