AUTOMOTIVE ENGINEER CAREER
Automotive engineering is involved with examining the operating principles of automobiles. This may include electrical processes, hydraulic systems, mechanical system, and efficiency management. The automotive industry is a rapidly advancing sector, and includes many technological and computer-based systems. Some automotive engineering degree programs offer many courses in mechanical engineering, and automotive design engineering focuses on the interior and exterior components of vehicles. Automotive engineering colleges provide hands-on training and direct application for a variety of careers in the industry.
Automotive engineers design, test and develop vehicles and / or components & systems from the concept stage through to production. They are also involved in improving the vehicle in response to customer feedback once on the market. Specialising in areas such as aerodynamics, alternative fuels, chassis, electronics, emissions, ergonomics, manufacturing, materials, motorsport, powertrain, rapid prototyping, vehicle and pedestrian safety or supply chain management - they use both traditional methods and state-of-the-art technology to engineer vehicles to high standards of performance, safety & reliability.

PARTS OF YOUR CAR
Air cleaner/filter: Air is drawn through it. Contains a filter that blocks dirt before it can enter the engine.
Air intake manifold: Air is distributed into the combustion chamber.
Alternator: Takes over from the battery when the engine is running. Recharges the battery and supplies power to all electrical components.
Battery: Supplies the initial electrical power that starts the engine.
Carburetor: Most new cars now have fuel injected engines. Older vehicles have carburetors. This gadget mixes air and fuel in the proper ratio for burning in the engine's combustion chambers.
Coolant reservoir (tank): Holds hot coolant (antifreeze) that overflows from the radiator and also draws back into the radiator as it is needed.
Distributor: Distributes high voltage electricity to the spark plugs, one at a time.
Exhaust manifold: Set of pipes, one for each cylinder that conducts exhaust away from cylinders.
Fuel injection system: Sprays controlled amount of fuel directly into either the intake manifold or combustion chambers, resulting in a very precise air to fuel ratio that improves fuel economy.
Muffler: The interior "baffles" and tubes quiet the explosive release of exhaust.
Suspension system: This system receives a great deal of punishment from the roads. This system consists of shock absorbers, Struts, springs, and motor mounts, tires, tie rods, ball joints, control arms, torsion bar, strut rods, spindle, axles.
Power steering reservoir: This reservoir contains fluid for your power steering system. Once the reservoir cap is unscrewed the cap will consist of a dip stick. This will identify the fluid levels.
Brake fluid reservoir: The brake fluid level can be inspected by the plastic box or bottle by the fire wall on the driver side.
Disc brakes: A metal disk that spins with the wheel that the brake pad uses to pressure against to stop.
Oil dip stick: The stick that's used to check the level of the motor oil.
Rear Axle: A shaft that connects the power from the transmission to the wheels.
Radiator: The device that helps to remove heat from the cooling system as coolant passes through it.
Nickel-Hydrogen Batteries
The nickel-hydrogen battery is a sealed secondary battery, and combines the technologies of batteries and fuel cells.
Figure 1 displays a 6-volt 100-Ah terrestrial nickel-hydrogen battery. The cutout portion shows the various module components. The positive and negative plates attach to the busbar, and the battery contains a water line, a water inlet, and a pressure vessel as well.
Chemistry
The nickel-hydrogen battery has a nickel oxide positive electrode similar to the nickel-cadmium cell, and is like the hydrogen-oxygen fuel cell since it has a hydrogen negative electrode. This hybrid battery has a long cycle life, high specific energy, high power density, and also exhibits tolerance for overcharge, and is therefore the choice battery in many aerospace applications, especially geo-synchronous (GEO) and low earth-orbit (LEO) satellites. In addition, the battery's hydrogen pressure is a good indicator of the charge state of the battery. Recently, nickel-hydrogen batteries have also been used in terrestrial applications. Its disadvantages include an expensive initial cost, as well as low volumetric energy density.
The positive electrode reactions happen similarly to those in the nickel-cadmium system. Hydrogen gas in the negative electrode becomes oxidized to water at discharge, only to be reformed at charge via electrolysis. Oxygen is formed at the positive electrode at overcharge, and there is no alteration of the potassium hydroxide (KOH) or water level in the battery during continuous overcharge. The positive electrode makes hydrogen during reversal, which in turn is consumed at the same rate at the negative electrode. In addition, hydrogen reacts electrochemically but not chemically, and reduces the nickel oxyhydroxide.
The sintered positive electrode is made up of a sintered porous nickel plaque, which contains active material of nickel hydroxide. The plaque conducts the battery's electric current, and retains the active material. An electrochemical process, either the aqueous impregnation process or the alcoholic impregnation process, forces the active material into the sintered plaque. Both processes load the active material uniformly within the pores of the nickel sinter, and also control the loading level.
