An automotive catalytic converter is a device that is placed inside the tailpipe of a vehicle. The device controls the amount of toxic pollutants being released from the exhaust pipe. It consists of precious metals (platinum and palladium) that catalyze (accelerate the rate of) redox reaction (an oxidation and a reduction reaction) that converts harmful exhaust gases to less toxic gases.

An automotive automatic transmission (AT) system allows the gears to be automatically changed, without the need for pressing the clutch manually. This type of transmission system is also known as self-shifting transmission or n-speed transmission and provides a wide range of speed and torque output. A vehicle equipped with AT comes equipped with automatic gearboxes, which are devoid of the conventional clutch pedal.

Power factor controllers are mainly used to control voltage fluctuations and maintain optimum power factor for eliminating interference during machine operations. Power factor controllers include both automatic and manual controllers. The applications of both these controllers are similar, the recognition mode being the exception. Automatic power factor controllers use an automatic capacitor recognition mode whereas manual power factor controllers must be adjusted manually in times of fluctuation or decrease in the power factor. Manual power factor controllers are suitable for testing relay outputs. However, the use of these controllers is limited as most of them are getting replaced by automatic power factor controllers. This is because automatic power factor controllers are easy to use and maintain compared with manual power factor controllers.

The use of 3D glasses has gained popularity over the years with the growth of the media and entertainment industries. In 1838, Sir Charles Wheatstone developed the first 3D viewing device called stereoscope by applying the principals of stereopsis. The stereoscope was a flat board fitted with mirrors and lenses and was enhanced by removing mirrors to make the view easier through lenses. This resulted in a device called lenticular scope, which was the first portable 3D viewing device.

Aluminum casting is a process of melting aluminum and injecting it into a hollow mold to get the desired shape. Aluminum castings are used in numerous applications due to multiple advantages like high tensile strength, molded inserts, fine surface finish and high heat resistivity. Aluminum cast components are used to manufacture subassemblies of vehicles, planes, and trains. These castings are also used in industries such as mining, construction, and electrical and electronics. The high demand for aluminum castings from small appliance part manufacturers and the automotive and machinery industries will boost the growth of the global aluminum casting market during the forecast period. The growing demand for lightweight and fuel-efficient vehicles is also a major factor contributing to the growth of the market. Casting products are manufactured using the following methods

Batteries provide power to devices such as smartphones, flashlights, watches and clocks, and electric cars. These batteries consist of an electrochemical cell with electrodes, which provide the necessary charge when connected to an external device. Alkaline batteries use an alkaline electrolyte of potassium hydroxide (KOH). It consists of a positive electrode made of manganese dioxide and a negative electrode made of zinc. When the battery is connected, electrons flow from the negative electrode to the circuit to power the external device connected to the battery. The flow of electrons forms an electric charge.
