Why do car engine So Noisy or Noisy

Car engine sounds unnatural is happening on a car's engine is usually sound like a knock. If the sound is still heard regularly beats the cause is usually on the system a.k.a. or valve. In a State of slow machine round the sound beats it does not sound clear, but by the time the rotation of the engine is accelerated so the beats sound is heard loud and clear.

Car engine noise may also be caused due to the valve gap is set too loose. If your settings are too loose and not in accordance with the manufacturer's specification settings, this can cause engine noise and the effect of the suction valve working period and the exhaust valve so it is less effective.

But conversely, if the gap is too small then the set valve valve-the valve tends to be in a State of elevated and result in the ability of the machine be declined because of the suction valve working period and the exhaust valves are not perfect and the engine compression to be less good.

Car engine noise can also come from components or other parts which wear out or damage suffered. For example, at the time the car is turned on, the noise sounded like metal beats you met. If the gas pedals to step on and held a few moments that noise disappears.

Sometimes noise is heard when the car is parked for too long, it could be in the morning when the car is being heated. Noise was coming from the engine timing chain or chains that have been worn or damaged. Noise or other noise that often sounds of the machine is the sound of creaking. Usually this sound comes from the fan belt is already too slack, it could also come from the compressor AIR CONDITIONING.

For sound or the sound of creaking that comes from the air conditioning, if the sound of creaking harder when AC is alive, this is because the bearing of the compressor or the compressor shaft seal is already worn out. But if the air conditioning is turned off and at that moment the sound of squealing louder means caused by pulley bearings are worn.

Sound or noise is not normal is the only crackling sounds once when the engine or gassed launched full. This is usually caused by the propeller tip to touch the radiator cooling fan or fan guard.

This usually happens on cars that have rear wheel drive system. This occurs because the engine cradle are loose or damaged rubber causing the machine moved forward suddenly when the gas pedal.

The Workings of the Machine Two Step

The first step is the piston moves from BDC (bottom dead center) to TDC (top dead center). By the time the piston rises to the top, then the fuel entry whole open and fuel is sucked from the carburetor into the room on the vessel at the bottom of the piston crank.

At that time also the flushing hole and drain covered by the shaft. Then going down the shaft resulted in compression in the crankcase crank, and then there is fuel in it is pressed into the top hole towards flushing.

Hold the shaft down to the BDC and approximately 10% of the shaft before reaching the BDC, flushing holes began to open up to the BDC. The compressed fuel in crankcase cranks up through the transfer port and fills up the cylinder at the top of the shaft.

Then the shaft rises again for the TDC and approximately 10% of the shaft after the flushing hole covered by BDC cardiothoracic surgery, at a time when 20% of the shaft after BDC that moment also a drain covered by the shaft. With the closing two holes then began the compression stroke fuel.

Meanwhile at the bottom of the piston pit entry and fuel began to open new fuel is sucked from the carburetor into the room like a crank. After performing the steps of compression then the fuel undergoing combustion process that is followed by return of the shaft to the bottom in order step effort or work steps.

After approximately 80% of the shaft after step through TDC, sinkhole began to open and process of disposal gas combustion residual to the BDC, and approximately 90% of the shaft after the flushing hole then TDC (transfer) is open and that there was also a sign of new fuel into the cylinder at the top of the shaft while pushing gas remnants out of the hole.

The process of disposal income and fuel into the cylinder at the same time is called flushing. Meanwhile, at the same time the entry holes covered by the shaft.

So the conclusion is that the work cycle the machine motor this two steps with just one rotating crankshaft can generate one horsepower. So the difference with four-step is if the machine four steps to do one job takes one full step while for two steps machine with just one step shaft can produce two work.

The Working Principle of a Four Step Machines

The first step is sucking fuel from the carburetor to the cylinder bore, after this step the piston moves from TDC (top dead center) toward BDC (bottom dead center) and at the same time the entry valve opens, while the exhaust valve closes tightly.

In this step, enter a mist of fuel through the entrance hole is passed on to the incoming valve and finally into the cylinder. After the process of sucking the fuel is finished and the position of the shaft are under, that's when the valve closes the entry so that the mist of fuel trapped in the cylinder.

The second step is the last step of compression fuel i.e. the shaft moves of BDC to TDC. At this stage the second valve in the State shut down the meeting so that the resulting compression of machine is good. Strong or weak energy produced is directly proportional to machine a good or bad result of compression, as well as a quantity of fuel mist who smoked in the first step.

At the time of the shaft before reaching the TDC in the end step compression, spark plugs sputtering flames and burning fuel mist so that it is making a hot high-pressure gases.

The next step is called a step or steps of work effort, at the moment the shaft moves from TDC towards BDC. In step this is the useful energy produced to run vehicles, while other measures thus require energy. At this stage the second valve is still in a State of closed meetings and just before the shaft up to the exhaust valve begins to open BDC.

The last step is a waste, at this time the shaft back moving from BDC toward the exhaust valve open and TDC while the valve entry closes the meeting. The movement of the shaft at this point serves to encourage the remaining combustion gases thrown towards the exhaust. After the end of the next stage of this exhaust step is to return to the first step to step up to this dump again repeatedly.
