Car Manufacturing; How the New Mercedes C class is made

The car manufacturing process is developing year on year. Several years ago it was done manually. Nowadays it is drifting towards a full automatic car manufacturing process. This article will briefly describe how the new Mercedes C class is manufactured.

The skeletal body of the Mercedes is made from weatherproof steel. This steel which comes in flat rolls are cut into various sizes and pressed moulded into the required shapes and body parts by heavy robotic machines.

The body frame parts are then transported to the assembly point where again, robotic machines assemble the car body frame, riveting, screwing or welding the parts to one another.

Next the assembled body frame is taken for painting. The robotic machines do the painting work.

The painting work is carefully inspected by human workers for any defects.

After painting is done and fully dried, all other parts of the car such as engine, wheels, headlights,and car interior are put in place.

Finally the finished manufactured car is carefully inspected and test driven before it is put up for sale.

The work of Shock Absorbers in your Car

shock absorbers

The work of shock absorbers is primarily to reduce the oscillations, up and down motions or vibrations your car makes during movement on uneven roads. It also enables your car to remain stable particularly at high speeds. 

A car with a bad shock absorber will result in a very uncomfortable  driving experience. The uncontrolled oscillations produced can result in damage to the under parts of your car. Occupants in your car too will have a rough ride.

Shock absorbers also known as dampers convert kinetic energy to heat which is in turn dissipated into the surroundings.

There are two types of shock absorbers;The pneumatic and the hydraulic types. 

The first type uses highly compressed gas as the damping component while the second type uses a viscous fluid as the main damping component

The hydraulic type is the most commonly used in vehicles.

Your car normally will have four shock absorbers, one by the inner side of each tire.

A major sign of a faulty or damaged shock absorber is hydraulic fluid leakage. You will see it on the body of the shock absorber.

To avoid damage to your shock absorbers, make sure to drive carefully on uneven roads. Avoid strong impacts into portholes or bumps.

Common problems your vehicle may have

Continuous degradation of fuel we use in our car engines produces some substantial amount of heavy and sticky residue. This substance can block fuel and oil flow through the engine. It makes engine parts wear out prematurely. Removing this residue from your engine will make your engine last much longer. Below are some problems you may notice with your car.

Car doesn’t come on or does so after several attempts.

If your car doesn’t start right away in the morning, or takes several attempts to do so. The car may be suffering from any of the following;

Substantial amount of dirt in fuel injector, carburettor or fuel filter, bad spark plug or coil, bad or faulty fuel pump.

Rough idle

Rough idle means the rate at which the engine runs when the throttle is not pressed.

Most car and truck engines idle steady at 600 to 1200 RPM. A good engine will idle smoothly and quietly. If your car is doing rough idle, you will notice that the engine looks shaky with a substantial amount of vibration and unpleasant noises. Causes include dirty fuel injector/carburettor, bad spark plugs and vacuum air leaks. 

Engine suddenly stops running.

It is called engine stall. its when the engine suddenly dies when its supposed to be running. Though the engine may start back up again. Stalling may indicate an inadequate amount of fuel or air going into the engine. causes include bad spark plug, bad coil or dirty air filter.

Hesitation

If your engine has a delayed response when you press down the throttle,then it may have the hesitation problem.Common causes include clogged fuel filter, dirty fuel injectors, failing spark plugs or plug wires, vacuum/air leak, weak fuel pump and bad fuel.

If your car doesn’t run, accelerate & climb hills as fast as it normally should then it may be suffering from power loss. It could also be caused by any, some or all of these;clogged fuel filter, bad fuel injectors, failing/faulty spark plugs or plug wires, vacuum/air leak, weak fuel pump and low quality  fuel.

In conclusion, for you car to operate smoothly have your car serviced at least every six months

How to care for your car battery

The battery in your car is designed to kickstart your car. It provides the needed voltage to the kickstarter necessary to start your vehicle. The commonly used battery is the sealed lead acid battery.The battery is usually maintenance free and when it wont charge properly anymore discard and get a new one. The lifespan of a typical car lead acid battery is 1-2 years..

How to care for your car battery

Never let the battery run down or discharge completely. Even a single occurrence can severely damage the battery. May sure head, parking and interior light are not on when you park and exit the vehicle. Make sure you switch  off the car completely and no appliance is discharging the battery when you are not using the vehicle.

Make sure battery terminals are well connected.

When battery light indicator comes on in the dashboard, quickly have the alternator and battery checked by qualified personnel

Peripheral electronic devices for use in your car should be used when the engine is running. 

If you use a do it yourself maintenance lead acid battery , always check the electrolyte level and fill with distilled water if it falls below the marked minimum.

Your car battery is not designed for inverter indoor use. Using your car battery for this purpose will quickly damage the battery.

Indications that your car battery will soon need replacement

  1. Engine fails to start quickly and smarter than before
  2. Battery Indicator comes on the dashboard
  3. You always have to tighten and retight the terminals a considerable number of times  you start the engine. 
  4. White residue on the battery terminal.
  5. Battery always discharges before the next morning.
  6. Battery performance has greatly reduced. Runs down quickly under little load.

Caution: When raising your Vehicle

Raising your vehicle means to lift up your car at the side (to change tires) or at the front and back (to work under the car).  Vehicles are raised using a jack.  Be cautious when raising your vehicle with a jack as any mistakes can result in serious injury.

Take the following precautions

  1. Do not put any part of your body or get underneath the vehicle supported only by the jack
  2. Always place the jack on a solid, level surface before using it to raise your vehicle.
  3. Do not start the engine while the vehicle is supported by only by the jack.
  4. Stop the vehicle on level firm ground, firmly set the parking brake and put the shift lever in P (automatic transmission) or R (manual transmission)
  5. Make sure that the jack is properly set at the jack point on your car.
  6. Don’t raise the vehicle with someone inside.

About Engine Oil Consumption of Your Car

Cars consume engine oil, but oil consumption is minimal.

Note that the amount of engine oil your car consumes will depend on viscosity, quality of the oil and the way you drive your car.

Your car consumes engine oil when you drive at high speeds and also frequent acceleration and deceleration.

A new engine consumes engine oil.

Normally your car should consume about one liter of engine oil every 1000km (600 miles).

If your car consumes much more then have it checked by a qualified personnel.

You should also note that engine oil drops on the floor under the car and oil stains on the engine body need to checked by qualified personnel.
