Built-in Power Generator

Have you ever wondered how the car batteries continually get recharged? The car batteries just seem to have endless supply of power even when they continually are being used. Car batteries are seldom replaced. Perhaps, it is only when there are leaks or during acid replacements that the car batteries are removed and recharged. On the other hand, you might also wonder: what is the source of electrical power of the car lights if the batteries only provide low voltage current? Obviously, the batteries cannot effectively supply the power needs of the car lights. The answer to these questions is the alternator.

The alternator is the built-in electrical generator of the automobile. It is the main power source that sustains combustion and powers the automobile lights. It is also the one that periodically recharges the car batteries. On the other hand, when it comes to the process of ignition, the batteries merely initiate it. The alternator is the one that sustains ignition. The batteries do not have enough power to sustain combustion. As a built-in power generator, the alternator derives its mechanical power from the camshaft. Consequently, it cannot operate if the engine is not running. If you want to maintain the power supply in your car while it is parked, you have to put the engine in idle mode. In this manner, the alternator can still function.

As the name implies, the alternator produces alternating current. This type of current is better because it has greater power and can travel at longer distance without losing significant amount of energy. This alternating current is produced by the alternator through the process known as electromagnetic induction. Inside the alternator is a permanent magnet rotor. A set of magnetic wire coils is installed on the interior wall of the alternator. As the rotor spins, its magnetic field is cut by the wire coils. This results in the flow of electrons on the wire coils. The electrons are pushed by the rotating magnetic field.

Distributor: A Rotary Switch

The automobile is not all about mechanical output. It is not all about speed, torque, power, and mileage. The mechanical components of the automobile are just one aspect of a coherent whole. The electronic and electrical components are also equally important. The mechanical components cannot function without the electronic and electrical components. Without these latter components, the automobile will be like an animal without a nervous system. Even long before the development of the onboard computer, the electrical parts are already built-in features. One of the most basic electrical components is the distributor. This component is responsible for regulating the flow of high voltage electrical current to the spark plugs.

To some extent, the distributor can be considered as a composite of mechanical and electrical parts. It has a rotor that is powered by the camshaft. In this manner, the distribution of electrical current can be coordinated to the motions and positions of the pistons. Electrical voltage needs to be precisely discharged by the corresponding spark plugs only when the pistons are in particular positions. Any delay or advance electrical discharges can cause fuel combustion inefficiency and even the breakdown of the engine. Hence, the distributor serves a crucial role.

To put it simply, the distributor is a special type of mechanical rotary switch. Its main role is to alternately and sequentially distribute high voltage current to the spark plugs. The distribution of electrical current corresponds to the motions of the pistons. A distributor is comprised of housing, a rotor, a set of carbon conductors, rotor brushes, and a cap with distribution points. As the rotor rotates, specific circuits of spark plugs are closed. This allows the flow of high voltage current. Each distribution point on the distributor cap corresponds to a particular spark plug. The spark plugs are connected to the distribution points via spark plug wires.

My Mazda Convertible

I always loved the open air. Nothing is more relaxing than driving a convertible at dusk during summer season. I usually take my Mazda Miata convertible for a spin whenever I feel stressed at work. I recently bought this car from a car show that I attended. I originally intended this car as a productivity gift for my trusted friend and employee, Jim, but I decided to give him the Dodge instead. I liked the Miata so much that I decided to include it in my collection. Unassuming as it is, this car is perhaps the most practical car that I ever bought.

In terms of performance and efficiency, the Miata is superbly engineered. It is light weight but has a powerful engine. Its engine produces an output of 124 kW or about 166 horsepower. Its torque is also equally impressive at 140 ft lb, allowing it to be highly maneuverable both on flat ground and on slopes. It is environmentally friendly partly because of its multi-point injection fuel system. In this manner, you can be assured that no fuel is wasted. This also means highly responsive and precise engine that automatically adjust to the mechanical demands of the situation. Fuel efficiency translates to zero pollution.

Aerodynamically speaking, the Miata is also impressive. Its highly streamlined body allows it to smoothly run at high speed. Since air resistance is significantly reduced, fuel is also saved. Instead of spending fuel in counteracting air resistance, fuel combustion is translated into speed and mileage. Its petit body structure also contributes to its aerodynamic maneuverability. On the other hand, in terms of handling maneuverability, this vehicle utilizes wishbone front suspension with stabilizer bar and coil springs. Its brake system is equipped with electronic brake distribution and ventilated discs. In other words, Miata is stylish, efficient, safe and comfortable to ride.
