You should take your vehicle to a service center if something seems to be off, but it helps tremendously if you know something about car maintenance yourself. It helps if you look at a car parts diagram, so you know where the most important parts in your vehicle are located. Learn about car parts so you can have more in-depth discussions with your service technician about how to adequately maintain your vehicle. Battery The battery is a critical component. It allows your vehicle to turn on in the first place. In a majority of cars, it will be located under the hood, and you can identify it with the (-) and (+) symbols. In the event you need to jump-start your vehicle, you need to connect the red clamp of the jumper cable to the (+) symbol and the black clamp to the (-) symbol. Axle The axle is responsible for transferring power from the engine to the wheels. It is an important part when you want to move, brake and turn. You can tell if your axles are in a state of disarray if they star

There are five different types of welded joints for bringing two parts together for joining. Five types of welded joints are butt joint, corner joint,  lap  joint, tee-joint and edge joint. 1. Butt joint: In Butt welded type, the parts lie in the same plane and are joined at their edges. 2. Corner joint: The parts in a corner joint form a right angle and are joined at the  center  of the angle. 3. Lap joint: Lap joint consists of two overlapping parts. 4. Tee-joint: In a Tee-joint, one joint is right angle to the other joint in the approximate shape of the letter “T”. 5. Edge joint: The parts in edge joint are parallel with at least one of their edges in common and the joint is made at the common edge(s).

Hydraulic Turbines  are also known as water turbines. Types of Hydraulic Turbines are listed below. Pelton Turbine : Pelton turbine is a type of impulsive water turbine Francis Turbine: Francis turbine is a type of water turbine.  They are used widely. Kaplan Turbine: We can notice the little variation from the Francis turbine Turgo turbine:    Pelton wheel modification is turgo turbine. Cross flow turbine: It is also known as Ossberger turbine or banki Michell Turbine. Wind turbine: The Wind turbines are operated at the single stage but there is working without nozzle and inter-stage guide vanes. Mercury vapour turbine: In the mercury vapour turbine working fluid is mercury. It is used to improve the efficiency of the fossil fueled generating station. In some power plants we can see notice the combination of the conventional steam turbine and mercury vapours. The toxicity of the metal mercury was quickly outward.

Tesla and other car companies are selling a record number of electric vehicles (EVs). But even at souped-up “supercharger” stations, the cars still require more than 1 hour to top off their batteries. A new advance may change that. One strategy for boosting battery charging speeds has been to raise the battery temperature during charging, which accelerates the chemical reactions inside the battery. But keeping batteries at high temperatures can cause components to break down quickly. Now, researchers report they can prevent this breakdown, and allow fast charging, if the heat is added just for short periods. By heating up a charging device to 60°C for just 10 minutes, they were able to speed the incorporation of lithium ions into layers of graphite that make up the anode (as shown in the above artist’s representation), the key step in recharging the battery. If scaled up, this would allow them to add 320 kilometers in driving range to conventional lithium-ion bat

Steam turbines  may be classified into different categories depending on their construction, working pressures, size and many other parameters. But there are two basic types of steam turbines: impulse turbines reaction turbines . The main distinction is the manner in which the steam is expanded as it passes through the turbine. Main Differences of Impulse & Reaction Turbines: Impulse turbine Reaction turbine 01. Steam expands completely in the nozzle. 01. Steam expands partially in the moving blades and partially in the fixed blades. 02. Pressure of steam remains constant during its flow through the blade passages. 02. Pressure of steam is not constant during its flow through moving and fixed blade passages. 03. Steam flow over the blades is uniform due to symmetrical blade profile. 03. Steam flow over the blades varies due to aerofoil section (unsymmetrical) blade profile. 04. Due to complete pressure drop in the nozzle, steam velocity and rotor speed are very high, resulting in c

Flat plate collector: In a flat plate collector, the radiation energy of sun falls on a flat surface coated with black paint having high absorbing capacity. It is placed facing the general direction of sun. The materials used for the plate may be copper, steel or  aluminum . The thickness of the plate is 1 mm to 2 mm. tubing of copper is provided in thermal contact with the plate. Heat is transferred from the absorber plate to water which is circulated in the copper tubes through the flat plate collector. Thermal insulation is provided behind the absorber plate to prevent heat losses from the rear surface. Insulation material is generally  fiber  glass or mineral wool. The front cover is made up of glass and it is transparent to the in-coming solar radiation. Cylindrical parabolic concentrator collector: Concentrator collectors are of reflecting type utilizing mirrors. The reflecting surface may be a parabolic mirror. The solar energy falling on the collector surface is reflected and f

In the future all electronic devices will be wirelessly powered. Small, battery-powered gadgets make powerful computing portable. The battery charger should be capable of charging the most common battery types found in portable  devices today.  In addition, the charging  should be  controlled from the base station and a bidirectional communication system between  the pickups  and base  station  should be developed. Inductive Power Systems: Inductive Power Transfer (IPT)  refers to the concept of transferring electrical power between two isolated circuits across an air gap.  While based on the work and concepts developed by pioneers such as  Faraday and Ampere, it  is  only recently that IPT has been developed into working systems. Essentially, an IPT system can be divided into two parts; ●         Primary and ●         Secondary. The primary side of the system is made up of a resonant power supply and a coil. This power supply produces a high frequency sinusoidal current in the coil. 

A rivet gun is a very useful tool that fastens metal parts with rivets. Working with a rivet gun can increase productivity without degrading the quality of the finished product. There is more to the operation of a rivet gun is more than just learning the triggering mechanism. ●        A rivet gun is a special type of tool that is used to drive rivets into metallic objects to bind them. This tool is also known as a pneumatic hammer because it is a pneumatically powered tool, i.e., it uses pressurized gas to drive the force. When a rivet is used to fasten metal pieces, the gun produces the head of the rivet while a bucking bar is used to tighten tail. Rivet guns that are used for fastening steel parts are quite large while those used in aircraft assembling are comparatively small. They differ from air hammers only by the level of driving force; the underlying concept used in both the tools is same. How the Rivet Gun Works ●        There are various sizes and shapes of rivet guns with dif
