The Cause of Burning Is Not Perfect On The Car

On a combustion gasoline engine is carried out at some point before the top dead point when compression step. That's when spark plugs sparks in the engine combustion chamber. In engines where the fuel system is still conventional or still using a carburetor as a mixer, the mixing of air and fuel will not be as precise and in accordance with the condition / vehicle load as in the fuel system that has been injected.

Although in fact very rarely even there is no car that burning engine room occurs perfectly seratur percent. Then the next when viewed from the chemical formula, the perfect combustion of combustion in the engine where gasoline (C8H18) with oxygen (O2) burned and produce Carbon dioxide (CO2) and Water whose chemical formula is H20.

If combustion is perfect then transmisi manual mobil the formula will be like that, and the result of the flue gas will only contain CO2 and H20. But in fact the combustion on gasoline engine can not perfectly, hopefully there will be able to create and find the latest and advanced technology to produce perfect combustion. This incomplete combustion will cause new gases, such as carbon monoxide (CO), HC, NOx etc.

There are some dryers that burn incomplete combustion, including the following:

1. Ignition system problematic

Ignition system problems such as spark plugs off, when ignition is not appropriate, spark spark on small spark plugs, etc can menyebapkan imperfect combustion, the problem on this ignition system can menyebapkan burning in the engine is not as expected, consequently the mixture of air and fuel is not can burn completely. So leaving the gasoline vapor or often known as hydrocarbon. When forwarded again when the ignition timing is not appropriate eg too backward, the ignition time is too short and the fuel does not burn entirely. Read: Three Damages On Car Spark Plugs

2. Overlaping of the valve

Overlapping valves or opening valves simultaneously will affect the combustion results, if overlaping is too long the fuel and unburned air will come out with the combustion gases, so that the same pollution and if the emission test of HC concentration in the exhaust gas will be high .

3. Incoming air is not pure oxygen only

In this free air the content is not only composed of oxygen alone, but there are carbon dioxide, nitrogen and other elements. These gases when entered and burn will form a new gas that may be toxic. Let's say that nitrogen gas (N) that combines with or oxygen (O2) will produce NOx.

4. Pure fuel

Purpose of the fuel is not pure that some of the fuel used is mixed / coupled with certain chemicals that aims to increase the octane value of fuel, one of the losses obtained is to produce residues such as lead (pb) that cause pollution.

5. Low compression

Low compression is also associated with less tightness between the piston ring and cylinder wall, so that fuel and air can pass through the slit. Conditions like this will make the kada hc in the exhaust gas increases.

6. The air filter is clogged

Well, not smooth the entry of air into the combustion chamber can also be one of the incomplete combustion burner, for example, this blocked air filter will make the oxygen needs for combustion is not met. So the result of combustion is not obtained CO2 but CO (carbon monoxide) which is very dangerous for humans.

7. Mixture of air and fuel is not appropriate

Theoretically the comparison of the ideal mixture of air and fuel is about 14.7: 1. Which 1 kilogram of fuel will be exhausted when burned with 14.7 kg of oxygen. Then if (water fuel ratio) approaches this figure the combustion will also be near perfect. Then on the contrary if it turns out the air fuel ratio is not suitable or far from ideal afras for example too wasteful then the combustion will be imperfect and produce levels of hc and co in the exhaust gas not according to the allowed specifications.
