Fuel Injection Systems

All gasoline-powered engines require only two basic elements to run - the proper quantity of fuel for any given rpm and throttle opening, and spark from the ignition coil at the right moment. A carburetor's fuel-delivery system is compound of distinct fuel circuits, each with a specific job to comply. During startup of a cold engine, the choke circuit adds supplementary fuel and air to maintain engine from stalling. When the engine reaches operating temperature, the choke circuit shuts down. At idle (as the throttle is opened), the idle mixture from the screw and transfer port circuits allocates extra fuel as needed by the engine. As airflow into the engine raises, the main fuel circuit regulates fuel flow related to the proportion of throttle opening. If the throttle is opened unexpectedly, an accelerator pump circuit squirts fuel straightly into the intake manifold.

Even though carburetors have supplied fuel delivery services for well over one century and have always basically worked pretty well, there are several things they simply can't handle. A carburetor is fundamentally a hunk of aluminum with a number of holes drilled into it. As air pressure within the carburetor changes, fuel and air flow through the diverse holes and into the engine. However, a carburetor's capacity to deal with constantly changing operating environments is restricted with regard to reactions to modifications in altitude and compensation for engine temperature. They also lack accurate fuel control for emissions purposes and produce overall excessive fuel consumption pending steady-state engine operation and acceleration. In brief, carburetors are just too dumb to continue being helpful for providing accurate air/fuel mixtures in present vehicles. What is required is a fuel delivery system with some brains.

Why Buy a Nickel Plating Kit

It's important to choose the right nickel plating kit for your needs. While there are professional nickel plating companies you can take your old and vintage car parts, motorcycle restoration parts and bicycle parts, these businesses will always work to make the most money possible for their nickel plating services. There is nothing wrong with a business trying to make money but there may also be a better way for the weekend plater to get the most for their money.

A smart move is to buy a nickel plating kit from an online or local dealer. Isn't working with your own material what working on a hobby is all about? Why take a motorcycle part into a plating shop when this is something that can be done inside one's own garage or at-home workshop? One thing to keep in mind is that there are chemicals involved in the kits but modern plating kits are said to be safer and more accessible than kits in the past.

Insurance Claim Tips for Auto Glass Repair or Windshield Replacement

Accidents or damage to a vehicle's windshield happen from time to time, and when that happens, it is essential to be aware and know the information of your car insurance to see how it can be paid for. Windshield claims, which fall under the area of comprehensive auto insurance, deals with damage to the windshield in the form of chips, cracks, or severely damaged windshields. If the driver carries comprehensive insurance (liability coverage only covers the cost of other vehicles/persons), the person is able to file a claim to entirely cover or partially cover the cost of a repair or replacement. This has to do with the deductible, and varies from policy to policy, and from state to state.

Before a claim is filed, however, it is important to consider a couple of things. First, you should identify what your insurance deductible is, and second, an auto glass quote should be obtained to see how much the cost of the repair is. These things need to consider in that the number of claims can sometimes elevate the customer's premium. Here is an example: Let's say that your auto glass deductible is $300, and after you obtain an auto glass quote to fix your windshield the total was $330. It is here that you will have to decide that filing a claim, in which the insurance company would pay $30, is worth having a claim on your auto insurance history.

How Often Should I Change My Brake Pads?

You have had your vehicle for three years, you have put 45,000 miles on it, and the only maintenance repairs that you have had to put into the vehicle are a few oil changes. You usually don't worry about your vehicle unless a trouble light comes on, but suddenly you notice your vehicle screeching whenever you come to a stop. You assume this is being caused by the brakes but you have never had to do any brake repairs before, so you ask yourself "How Often Should I Change My Brake Pads?"

If you are uncertain you should have a mechanic inspect your brake pads to see how much of the pad is left. It is recommended that you have this done every 20,000 miles. There is usually a large range for when brake pads are changed on cars. A heavy-duty truck that is driven by an aggressive driver (brakes hard), mostly in stop-and-go city traffic may have their pads wear out at 15,000 miles. On the contrary, a small car that is driven with care and mostly on the highway may not have to replace their brake pads until 45,000 miles. Other factors such as the quality of your brake pads and whether they are semi-metallic or ceramic will also play a factor in when you need to change your brake pads. It is important to note that if you have 4 Wheel Disc Brakes, you will probably have to change your front set more often than your rear set. This tends to be the case for 90% of the vehicles on the road.

Tips for Saving on Brake Repair

Brake repair is never something a car owner should put off. If there are any indications that the braking system on a vehicle is not working to the highest standard, it is necessary to bring the vehicle in for an inspection. Doing so may take only moments but the peace of mind it offers to the driver can be very important. Prior to investing in any service, though, it can pay to know a few ways to save money. In nearly all situations, consumers will find more than one way to reduce the costs associated with these repairs.

Do Ask for the Discount

When calling a brake repair location to schedule a service, ask about any discounts or promotions currently available. When you do this, you open the door for the company to provide you with a reason to make an appointment. Often times, they will negotiate a deal with you especially if a competitor has a promotion running. The only thing you have to do is to ask for the discount. Sometimes, it is possible simply to ask for a lower price or to ask for a free inspection. You do not have to expect the company to be running a promotion. Ask for a deal and the manager may provide it to you.
