Remain Engine Stable in Idle Position
Wasteful consumption of fuel is not only caused by improper driving style, road traffic, but can also be influenced by our engine settings. Especially from setting mixture of fuel and air that are less fit. Could be, setting the engine's fuel ratio right so the mixture does not become "fat". Called "fat" because the supply of fuel to the combustion chamber is larger than needed.
That is why setting the air and fuel mixture affects the least wasteful fuel consumption. Well, to find out whether or not fitting arrangement, it is very easy. One of them can be detected when the engine is in the idle position. If the engine RPM up and down, it's a sign setting ratio of fuel and air that are less fit. Supposedly, after the ignition is turned to the START position and engine life, RPM remains stable when we leave on the gas pedal.
Therefore, beware of machines that are not stable in the idle position. In addition to causing more wasteful consumption, it is possible engine suddenly off when the car is racing toward us in the middle of the road.
How to know the arrangement of fuel and air mixture that does not fit with the simpler method is through emissions testing. Just try to follow the activities of free emissions testing, when the paper test results indicated levels of HC and CO are too high, meaning that the fuel into the combustion chamber is larger than necessary due to an improper setting.
The solution is simple. Lives rearranged mixing ratio of fuel and air in the vehicle. Any routine service at the garage was usually mechanical inspection and adjustment of the ratio of fuel and air burning is often called CO set.
Nevertheless, it is quite possible if the adjustment is just right but remain incomplete fuel combustion. To be sure, do the inspection throttle body. Most likely components where the flow of air is dirty and disturbing the smooth flow of air into the combustion chamber.
In addition, check the ignition system. Perhaps there is a dead spark plugs, coil worn or detainees in the ignition spark plug wires too high.
