When you have a car, you need to know how to take care of it. You’ll want to make sure you understand the different things that can go wrong and when you need to fix it. One of the parts of a car that you need to pay attention to is the alternator. The alternator is a vital part of the car. Inside the vehicle, the alternator takes mechanical energy and converts it into electrical energy. This is stored in the car battery.
The alternator is not an insulated part against moisture
The alternator is not waterproof and when or if it is submerged you will need to check it. Repairs are necessary for your car to function properly. If you have the ignition on, you will see a battery light appear on the dashboard. It can also come on while you’re driving, which means you’ll need to have it checked.
Give your car the attention it deserves
Sometimes you may notice that your headlights or dash lights flicker or go out completely. This happens when the car is idling. You will find that while the engine is running, they will become brighter. If this happens to your car, you may have a bad alternator. You will want to find out if it is the alternator or a battery that is going bad. You’ll want to make sure your car is running smoothly at all times.
Do more
Starting in the 1980s, car manufacturers switched from using carburetors to a more advanced system – electric fuel injectors. As such, the car is equipped with sensors that measure the outside ambient temperature. This system allows the electric fuel injector to adjust the air-fuel mixture to account for cold weather. Typically, an electric fuel injector will create a fuel-rich air-fuel mixture, releasing more gasoline, compensating for low evaporation levels.
"Excellent service and honest mechanics. I always come when I have a problem with my cars and I always recommend this place to everyone.”
With this in mind, when you let your car idle, you use more fuel with little or no benefit. After all, your car’s engine has been optimized to run at low temperatures without the car stalling. The only reason to stop your car is to warm up the cabin and defrost the windshield, which should take about 3 minutes.
If you keep your vehicle idling for 10 to 15 minutes before starting your journey, it will increase the pollution. With much of the fuel leaving the engine unburned or partially burned, your car will release a lot of toxic fumes.
Why do many people think that warming up the car at idle in the winter is paramount?
Internal combustion engines work by mixing gasoline with air in the engine’s cylinders. Once the air-fuel mixture is compressed, the mixture is ignited by the spark plug, which moves the pistons. In years past, especially before the 1980s, a carburetor controlled the mixture of fuel and air. A disadvantage of the carburetor was its inability to precisely control the fuel in the air-fuel mixture.
Since gasoline has a hard time evaporating in cold weather, the carburettor was liable to release much more fuel than necessary.
The rich fuel mixture increased the potential for engine damage once ignited.
Car owners are advised to let their car idle for a few minutes to allow the engine to warm up and therefore make it easier to feed the carburettor with the right fuel mixture.
When do you need repairs?
The mechanical parts of the alternator are sealed, but standing water can damage it as the lubricant wears out. Repeated exposure to water can cause damage to the brushes due to arcing and wear. Early detection is always better. Check the signals on the dashboard while driving, if the ignition is on, it will show a battery light on the car dashboard. This means you need to look at it quickly.
