The electrical system consist of the generator (alternator), the regulator, the battery, the starter, and of course all the necessary wiring.
Generator (alternator)- The generator converts the mechanical energy, which it obtains from the crackshaft through a pulley and belt system, into the electrical energy needed for ignition, lights, and all other electric accessories the vehicla contains. It also recharges the battery. The generator consist of two basic parts: the Field Coils which create the magnetic field and the Armature Winding which rotates in the magnetic field producing a flow of current. It's common to have a fan attached to the generator to help cool the system.
Regulator- The regulator controls the generator's output according to the needs of the electrical system.
Battery- The battery stores electrical energy for starting the engine and the operating electrical units when the output produced by the generator is not sufficient. It principle is to convert chemical energy into electrical energy. Batteries are built in a series of cells, each producing approximately 2 volts. A 6 volt battery will then have 3 cells and a 12 volt battery will have 6 cells. The cells are all connected in series.
Starting Motor (starter)- This is a special type of an electrical motor designed to crank the engine at a speed high enough to permit it to start. It is capable of operating under heavy overload and creates great power, but only for a short time. When the starter is engaged, the driving pinion gear, which is attached to its shaft, is thrust forward to engage the teeth of the flywheel. The flywheel rotates the crankshaft to which is mounted, thus cranking the engine. As soon as the engine starts up, the driving pinion is automatically disengaged from the flywheel.
The ignition system is designed to transform the low voltage from the battery or generator to the high tension voltage required to produce the sparks that ignite the compressed mixture of air and fuel in the combustion chamber. This system consist of the ignition coil, the distributor, the spark plugs, and high and low tension wires.
Ignition Coil- This is a transformer designed to step up the 6 or 12 volts from the battery to approximately 20,000 volts.
Distributor- The distributor which is driven by the camshaft, sends the high tension current it recieves from the ignition coil to the proper spark plug at the correct instant that the corresponding piston reaches the top of the compression stroke.
There are three parts exterior parts to these injectors. The injector nut holds the nozzle and spacer with the nozzle springs. The injector body holds the plunger and barrel, it is also where the solenoid is bolted down on top of the body. The solenoid is plugged in to the pigtail on the valve cover gasket, which sends electrical current to the injector telling it when to fire. There is a total of five o-rings on the exterior side of the ...
Insert the key, turn, and vroom. And down the road you go. Most people take for granted the strange conglomeration of metal and plastic under that sheet of metal either in front or back of their vehicle. The engine as you may have guessed, is modern marvel- so to speak. They’re found in cars, trucks, boats, airplanes…All with various power outputs.
The first type of forced induction system is the turbocharger. A turbocharger is essentially the same as a supercharger, except where they get their power from. A turbocharger is powered by exhaust gasses that have been produced by the engine and are forcing their way through the turbofold, or the exhaust manifold that the turbo is housed in. The exhaust gas pushes its way through the turbocharger and hit the turbine wheel. Vehicles that usually find the need for a turbocharger from the factory are four or six cylinder engines. Standard in most European vehicles such as Mercedes, Audi, Volkswagen and Volvo. These cars are known for their small displacement motors, and great gas efficiency, due to this setup...
The Automotive, or electric car industry particularly, comprises all those companies and activities involved in the manufacture of electric motor vehicles (EV), including most components, such as engines, bodies and rechargeable batteries or another energy storage device. The industry’s principal products are passenger automobiles. Despite the fact that the first electric cars were produced in 1880s , the advances in internal combustion engines, especially the electric starter, soon diminished the relative advantages of the electric car and became the dominant design in the market. Due to this the EV was almost a forgotten industry staying in the early stage of development, conforming to less than 1% of the automotive stock
In the future the automotive industries will need alternative fuel sources, in turn that means they will need alternative engines in their automobiles. The engines found in their cars will have to be changed to fit the new fuels being made. They have many directions in which they can go concerning engine types and fuel types.
These cars operate from a rechargeable battery and gasoline. The engines are smaller so that they will be able to accommodate the 99% of time when the car is not going uphill or accelerating quickly. The battery is used to give extra acceleration power if needed. When the car is stopped, hybrid gasoline motors can shut off and run off their electric motor and battery. These cars are aerodynamic and the tires are often stiffer and inflated higher to reduce dragging.
A four stroke engine is the kind most commonly found in automobiles, and operates in four distinct steps or “strokes”; induction, compression, combustion and exhaust. On the first stroke, the piston moves downward and causes a pressure in the cylinder which is less than the atmospheric pressure outside of the engine. As a result, the air outside of the engine moves into the cylinder where there is less pressure, and is actually forced in because of the now higher pressure outside of the piston. On the second stroke, the piston moves upward and compresses the air with gasoline. The sparkplug ignites the mixture which combusts and moves the piston downward for the third stroke. This is where the power of the engine comes from. The piston then returns upward for the fourth stroke in order to push out the exhaust gases. Because the power of an engine is dependent upon the volume of air that can be drawn into the cylinders, it becomes limited at a certain point when the cylinder reaches its maximum negative pressure, and no more air can be sucked in. Not even an efficient engine, which at best is said to be on...
For over a century people have relied on automobiles, planes and trains as means of transportation, industry and agriculture, it has become such a successful necessity in the modern world that it has become a need for people to use them to get by. Now sure the three basic means of transportation are entirely different in the way the function and their use. All of these means of transportation would not be possible without this invention transportation could not be possible, The Internal Combustion Engine. You might be wondering what is exactly is an Internal Combustion Engine? It’s actually a simple concept but the way it’s performed can becoming very complex. The function of is to create a pulling force through a controlled explosion of compressed air and fuel inside a combustion chamber which then pulls a crank. Depending on what type of platform the engine is on will determine what the crank turns, for an example in a car the crank then turns either a front or rear axle which that axle transversely turns a wheel. In order for this engine to function in needs three elements - air, fuel and spark and without one of these elements the engine will not function, so it takes precise timing and careful planning by the Engineers to make the engine work as required.
An electric motor is a device used to convert electric energy into rotational kinetic energy. There are two different types of electric motors, and each has there own use. The different types are direct current and alternating current motors. Each of these motors will be analyzed in the following.
?In a series hybrid, the internal combustion engine drives a generator that charges the batteries, whic...
The steam engine is a peripheral ignition mechanism, wherein the operating fluids are disconnected from the ignition results. Non-combustion heat resources like nuclear and solar powers or geothermal power could be utilized. Water resorts to vapour in a reservoir and arrive at high pressures. When developed through turbines or pistons, automatic exertion is completed. The condensed-pressure condensation is then compressed, and reverse-pumped to a boiler. Several convenient steam engines remove low-pressure steams rather than compressing it for recycles.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
Wind turbines are a great source of energy around the world. Wind turbines produce wind energy that can be used to power our homes. Wind turbines convert kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity.
An electric vehicle is different from a gasoline powered vehicle. It is powered instead by an electric motor that receives current from rechargeable storage batteries, or portable sources of electrical energy.
The stator is the stationary component while the rotor is the rotational component of the motor. Usually magnetic fields are created when an electric current is applied to a set of conductive wires wound together (Dixon, 2001). Magnetic fields can also be created using Permanent Magnets (PM). Electrical motors can also work as electrical generators (Correla, 1986). Electrical generators are devices capable of converting mechanical energy into electrical energy. An example would be a wind turbine which works as an electrical generator. It converts the mechanical energy of the rotating shaft caused by wind into electrical energy (Correla, 1986). The focus of this research will ...
