    What is an engine or car engine?

    An engine is a machine designed to convert one form of energy into mechanical energy.

    How does it work in cars or automobiles?

    A car engine is to convert gasoline / petrol / diesel into motion so that your car can move. The easiest way to create motion from gasoline / petrol / diesel is to burn it inside an engine and convert heat energy into mechanical energy.

    What are the most common problems in engine?

    Most common reasons behind a engine failure is normally few mere problems like excessive smoke from tailpipe; excessive oil consumption; knocking or tapping sounds; low oil pressure; low compression; water mixing in oil and oil getting into the air cleaner and/or radiator, etc.

    How to diagnose engine problems?

    Unusually engine noises, low oil pressure, engine overheating, loss of power, misfiring, hard starting and similar driveability and performance complaints can all be indications of engine problem.

    How many engines present in the car?

    Although there are exceptions of having multiple engines in a car, but normally cars have only one engine. Few vehicles like tractors have even six and seven engines too. Actually only limit is space, weight, money and imagination.

    You should take your vehicle to a reputable automotive repair shop, dealer or engine installation center for diagnosis and replacement. You have to provide them your car make, model, engine size, engine type and etc. to find a proper replacement.


    Intake manifold or Inlet manifold:


    What is Intake Manifold or Inlet Manifold?


     An intake manifold, which is also called inlet manifold, is a series of tubes attached to several engine parts as well as to the carburetor, if the motor is not fuel injected. The key players in an engine system is the intake manifold.


    Where is Intake Manifold located?


     The intake manifold is aluminum, steel or plastic cover that sits on top of the engine. 


    What are the main functions of Intake Manifold?


     The main function of the intake manifold, or inlet manifold, is to evenly distribute the air-fuel mixture to the cylinders as well as to the carburetor on a non-fuel-injected engine. The manifold directs the fuel mixture in the engine to the correct cylinder, and then cools down the cylinder to keep the engine from overheating. The intake manifold achieves this cooling by running coolant through the manifold and towards the cylinder heads, where the coolant absorbs heat. 


    What are the main parts of Intake Manifold or Inlet Manifold?


     Following are the main parts of Intake manifold or Inlet manifold,


    ·         Plenum and Carburetor Flanges

    ·         Throttle Body Flanges

    ·         Plenums and Elbows

    ·         Throttle Cable Brackets

    ·         Runners and Velocity stacks



    What are the main causes of Intake Manifold or Inlet Manifold?


     Expansion, contraction, and heat from the engine cause the gasket to fail. This will cause coolant passing through the intake manifold to leak. A leaky manifold gasket can also result in air being sucked through the leaky gasket, resulting in a vacuum leak and poor engine performance.


    How to fix Intake Manifold or Inlet Manifold?


     If there is a coolant leak then, in most cases, using K-Seal will help to quickly and permanently stop the leak, saving a lot of time and money. We can also remove this problem by using these methods,

    ·         Scan the computer in the car for codes.

    ·         Inspect intake manifold for any signs of leakage.

    ·         Pressure-test the cooling system.

    ·         Remove and replace the intake manifold gaskets.

    ·         Clear any diagnostic code.

    ·         Run engine and test drive vehicle.





    What is Car Alternator?

    The definition of alternator is hidden in the name of this machine itself. An alternator is such a machine which produces alternation electricity. It is a kind of generators which converts mechanical energy into alternating electrical energy. It is also known as synchronous generator.

    Where is Car Alternator Located?

     Alternators are typically found near the front of the engine.

    What are the main types of Car Alternator?

    According to application these machines are classified as-

    1.    Automotive type - used in modern automobile.

    2.    Diesel electric locomotive type - used in diesel electric multiple unit.

    3.    Marine type - used in marine.

    4.    Brush less type - used in electrical power generation plant as main source of power.

    5.    Radio alternators - used for low brand radio frequency transmission.


    Define main functions of Car Alternator?

     The alternator works with the battery to generate power for the electrical components of a vehicle, like the interior and exterior lights, and the instrument panel. An alternator gets its name from the term alternating current (AC). Alternators produce AC power through electromagnetism formed through the stator and rotor relationship. The electricity is channeled into the battery, providing voltage to run the various electrical systems.

    What are the main Causes of Car Alternator?

    The most frequent symptom of a problem with your vehicle's charging system is a battery-shaped warning light (in the photo) or the "CHARGE" icon that comes on while driving. Normally this warning light should come on when you turn the ignition, but should disappear as soon as the engine is started. If it stays on, there is a problem with your charging system. The charging system warning light doesn't point directly to a failed alternator, although alternator problems are very common. Your mechanic will need to do further testing to pinpoint the defective part. Sometimes when the alternator becomes weak, you may notice that your car's headlights and dash lights become dim at idle, but get brighter at higher RPMs.

    How to check Car Alternator?

     To check if your alternator is faulty, you will need a digital volt ohmmeter or DVOM (aka voltmeter). With this tool you can quickly and easily see how much voltage your alternator is putting out.

    The first thing you should do is turn your engine off. You will need to start your car for a later test, but for now just leave it off. Take your voltmeter and put the red lead on the positive post of the battery and the black lead on the negative side of the battery. Be sure your voltmeter is set to read DC volts.

    It should read above 12.65 volts. This would indicate that the battery is fully charged. If it is not, then you either have alternator problems or a battery that is faulty.

    The next thing you need to do is to remove the leads from the battery and start your car. Then put the leads back on being careful not to get them caught in the serpentine belt or any other part of the engine.

    Read the voltage with the engine on. It should read somewhere in the 13.5-14.5 volt range. If it does then most likely the alternator is just fine. It is possible that it is still bad though, sometimes they are intermittently bad. If it proves to be good then you probably have battery problems. It is time to get the battery tested.


    How to fix Car Alternator?

    Test the alternator to make sure that it can start up the battery. If the battery is working properly and nothing is wrong with it, then it's the alternator that will more likely cause a problem. A simple test to check the working of the alternator is by running your car; and then unplugging the positive connection of the battery. If the car stops, then you most likely have a problem with the alternator. Another simple test is to check your interior lights. An alternator charges your battery when the car is running. If the interior and dashboard lights come on brightly but slowly start to fade, then it indicates a problem whit the alternator. It demonstrates that the alternator cannot keep a charge when the car is running. Another sign is that the car lights run brightly when you race your car, but when you slow it down, the lights start to lose power.

    We also recommend that if you have a dead battery, get a jump start done and check the battery and alternator at the garage. Most garages will do this absolutely for free and it just takes about five minutes.
