1. For lubrication function
Turn off engine cause the lubrication functions is stop. The function of lubrication is important, among them to reduce wear on components such as gear to gear friction, piston rings with the cylinder wall, and others. The longer die, the more oil that fell or returned to storage.
Surely the oil that is on the gear, piston and so on will be depleted. When the machine is turned off for a long time after it took a while for the oil to lubricate the parts rub against each other or gear. If you leave just like that, with a little lubrication, gear-gear can be worn, piston rings can break causing the vehicle to break down. Well, this is the most vital thing in the importance of the heating process.
Piston moves generally 50 rounds in 1 second or 3000 rpm, this in a static state (without gas). What if you_ moving with a speed of 100 km /hr would be more than 50 rounds in 1 second!
2. For more perfect combustion
Before the machine is turned onyet, the fuel and air are still in their places. That it takes the process of mixing air and fuel to get the right mix of fuel and air between about 1: 14.7 liters in size or can be mentioned 1 liter of petrol should ideally be mixed with 11,500 liters of air. This is how the mixingyet, the colors purple and green fuel air.
Motorcycle heated – air mixing At first not stationaryyet, mostly happens when gasoline vapors and sound like a firecracker – Finally after mixing stationary air was ideal – automatic firecrackers and fumes on the wane since the fuel burns more completely
Heat 2-3 minutes before the motor to work. Do not be too long because it can cause the exhaust so colored purplish or brownish to exhaust a silver or light-colored. This is caused by overheating due to exhaust air just running there-there just so there is no cooling
Engine cars and motorcycles require gasoline in accordance with the design of the machine in order to work properly and produce optimal performance. Types of gasoline are usually represented by a number / octane (RON), such as high-octane Premium 88, Pertamax high-octane 92 and so on.
The higher the octane number, the price per liter, were generally higher. But not necessarily that if the air-filled high octane gasoline on the engine / motor us, then it will result in a higher power as well. Well so what then?
If we look at the specifications of our vehicles, the good brochure will feature information compression ratio (Compression Ratio / CR). CR is the result of pressure ratio calculation related to the volume of the combustion chamber to measure the distance from the piston down to the most point while running. seen in the table, that the CR engine Toyota Avanza and Daihatsu Xenia is 11: 1
From the information brochure specifications, we can determine that we AX car engine requires gasoline octane value 95, ie gasoline Pertamax Plus.
What If Gas Filled With Lower Octane?
Low-octane gasoline more flammable. The higher the value of CR in the machine means that require high octane value of gasoline. Berkompresi high gasoline engine making rapid fire (due to high pressure), which would be a problem is, when gasoline burns early before spark plugs fire. When the piston up on compression, station lights preceded plugs, piston consequences such as being hit hard by the explosion of the combustor. We often hear the term “knocking”.
When there is p, gasoline is not a power in use. Work machine is not optimal. Back repeated, the CR engine is high, requiring a slow-burning gasoline. The higher the value of CR, the slower burning gasoline have (high octane).
Well, so to my friends, look at the value of CR engine / motor we (can peek at the list below), fill in the appropriate fuel for the engine.
- It is recommended for gas according compression ratio. (unless there are other modifications).
- The HIGH octane rating, the slower the fuel burns (due to higher burn point).
- The HIGH octane rating, the more difficult evaporated gasoline (low evaporation)
- Gasoline failed burn (due to too high octane), can cause a buildup of scale on the engine or on the valve.
