Octane Fuel

Octane gasoline is a large number of indicators that can be given before the pressure of the gas ignites spontaneously. At each engine, air and fuel mixture is pressed by the piston up with a very small volume and then set on fire by sparks produced by spark plugs. As a result of the magnitude of the pressure, the air and fuel mixture can also ignite spontaneously before the spark from the spark plug out.
The principle used octane level for a machine needs to be well adjusted to the level of the engine compression ratio (ratio of air and fuel mixture). Like the water that poured needs to be adjusted to the size of the glass if the water does not spill and would be redundant.
When the engine compression ratios ranging from 8: 1 to 9: 1 then the required octane gasoline for the engine no more than 92, the minimum 88 If you use 95 or 98 octane when the engine compression ratio of not more than 9: 1 then most likely what happens is the engine performance may not be better. Due to the use of higher octane, longer burning time and this must be balanced with the content ratio larger air inside the engine, so that performance can be maximized.
The use of high octane for high compression ratio can further increase the efficiency of fuel use, because gasoline burning longer than using a lower octane. So use octane gasoline that does not comply with the compression ratio can result in waste. As the diesel engine uses the term cetane numbers starting from number 40 to 55 The high levels of cetane number and low sulfur content, the time of the burning of diesel fuel into the air longer effect on the increase in the diesel engine performance and exhaust gas levels were also becomes lower.
However, increasing the compression ratio, higher engine can be done with or perform semi pengorekan tuning can increase the power and torque of the engine between 15% to 35% depending on how many modifications are done by re your machine.
In some types of engines the timing degree can still be set to adjust the ignition is slow or fast, according to the octane level of gasoline used. But this is usually just to relieve the symptoms not improve or reduce the knocking engine compression ratio. Despite increasing engine performance there but very minimal. It also needs to be aware that by using a higher octane then this also can accelerate the rate of warming in your machine, and if your machine is old enough so be careful to avoid overheating as a result of the use of octane gasoline is too high. Well some of the things that also need to be observed when you buy and make refueling as follows:

     Make sure the octane number is used.
     In each vehicle, behind the petrol cap listed minimum octane gasoline must be used as a minimum of 88, 92 or 95 Better to avoid fatal damage to your machine, and can further improve the performance and working life, follow these instructions. If it is less obvious, can be asked directly to the nearest car dealership you. Especially for the vehicle warranty period is still valid, it is required to be asked to them to avoid the loss of the warranty period. For this type of diesel engine, diesel fuel is usually the type that must be used is not listed on the diesel tank cap. So safe you ask the technician directly to the car dealership nearby.
     Avoid adulterated petrol.
     Types of gasoline or diesel fuel to be had on the roadside usually slightly mixed with other chemicals or the quality of its cleanliness is very minimal. It usually makes it difficult to detect what octane or cetane number which contains the fuel. Ignoring these problems can lead to blockage in the ducts of gasoline or diesel fuel tank of your car. If this happens to your vehicle, repair costs are not fairly cheap. As to the type of vehicle diesel engines, due to the sulfur content is too high can lead to blockage in the diesel injector line, which begins with the difficult symptoms turned on and after it dies completely. The cost of repair is very high.
     Filling the gas station quality. To avoid refueling meter inaccurate or cetane and octane levels are not clear. Should always fill the gas station that has a good reputation. As in some of the Pertamina gas stations that must fit and quality, if not you can make a complaint to them or asked for compensation, in case of fatal damage to the machine. Or safe, you can also fill the gas station from the outside, such as Shell, Petronas, and Total.
     Try the full content. We recommend that you refuel your vehicle up to the full if possible. These are the tips to slow down the entry of dirt into the tank, as well as reduce the production of excessive air occurs in it. Thus the use of fuel became more efficient, especially for a considerable distance usage.
