Why can’t turbo cars use pertalite?
Turbocharger technology and its impact on engine performance
Turbochargers are now increasingly popularly used by automotive manufacturers to improve the performance of small capacity engines to be equivalent to large-powered engines. This component works mechanically by utilizing the exhaust gas flow to rotate the turbine which is in charge of pumping fresh air into the cylinder. Thus, the engine can produce more power without the need to increase the size of the engine.
Although capable of producing tremendous power efficiency, the engine equipped with forced induction systems has very strict maintenance demands. One of the standard rules that is very haram to violate is the strict prohibition on using low-octane fuel oil such as pertalite.
1. High air pressure multiplication effect inside the turbo engine combustion chamber
The main workings of the turbocharger system is to force a much more volume of air to enter the combustion chamber densely. The air compressed by this turbo compressor will automatically experience a very drastic increase in temperature before infiltrating the cylinder. When the high pressure hot air enters the piston, the effective compression ratio in the combustion chamber will increase many times over.
The internal conditions of the engine that are already very extreme require the use of fuel oil which has high resistance to high pressure. Pertalite which has only ninety octane ratings is not chemically designed to be able to survive in this super-solid environment. As a result, this low octane gasoline will become very unstable and prone to a defense malfunction before the ignition system works.
2. The phenomenon of super knocking as a threat to the destruction of machine components instantly
When pertalite gasoline liquid meets high-pressure hot air from the turbocharger supply, the combustion circulation will be completely chaotic. The low octane fuel will explode by itself due to the compression temperature that is too high, even before the spark plugs have time to splash the sparks. The phenomenon of premature combustion that occurs massively in turbo engines is known as extreme knocking or high-level detonation.
The explosive power of this super knocking symptom has a much more destructive mechanical stress strength than the tickling symptom on a regular machine. This very powerful shockwave hit will collide directly with the movement of the piston that is moving up to the top. This collision of energy in the opposite direction can destroy the surface of the piston, bend the piston handlebar, causing the engine block to break in seconds.
3. The importance of high octane consistency to maintain vehicle mechanical safety
In order to avoid the risk of engine damage that costs tens of millions of rupiah, the use of high-octane gasoline is a fixed price. Fuel with a minimum octane number of ninety-two such as Pertamax or higher has the right resistance to compensate for the performance of the turbo wheel. The combustion in the cylinder will be created neatly, homogeneously, and produces optimal torque thrust according to the original design of the manufacturer.
Modern car computers do have a sensor system to rewind ignition time when detecting beats, but the system has a tolerance limit. In machines with forced induction systems, the delay in computer response delays in overcoming knocks can be fatal to the integrity of the cylinder. Therefore, discipline in choosing the type of high-quality fuel oil is the main key so that the performance of the turbo engine remains durable and powerful.
