Detonation phenomenon

The phenomenon of detonation and pre-ignition are two problems that affect the operation of the engine and must be fixed, to not compromise the life of the engine and also to avoid excessive fuel consumption, power loss and high emission of pollutants in the atmosphere.

The pre-ignition is a phenomenon caused by various reasons. One is the appearance of carbon deposits on top of the piston and the cylinder wall. This burning coal, causing the mixture of fuel and air explode before the third time in the engine cycle. This explosion may occur in the second time of the engine cycle, when the piston goes up, compressing the mixture by generating pressure and increasing the temperature of the gases, along with the coal, causing the mixture to explode prematurely. Other factors that cause pre-ignition are hot spots in the combustion chamber, excessively hot plugs and adulterated fuel, generating much carbon residue. The BE-Fuelsaver (PINOX) eliminates dirt residues in the engine, saving in maintenance and preventing pre-ignition.

The detonation phenomenon also occurs within the cylinder and is very similar to the pre-ignition, mainly caused by adulterated fuel of low octane, making the mixture explode before time. Lean mixture, inhomogeneity and early ignition also cause the detonation phenomenon. One factor that causes spontaneous detonation inside the cylinder is the high compression ratio in modern engines. To extract greater engine power, the combustion chamber is smaller, raising the compression ratio at high levels and contributing, along with the other factors mentioned above, to the effect of detonation. The consequences of this thermodynamic phenomenon can vary from bad to catastrophic. Engineers have developed many technologies to identify and avoid detonations and currently almost all new engines have systems to combat the phenomenon.

In addition to the conservation balanced characteristics of the motor through regular maintenance and, if necessary, a preparation made with discretion, the detonation can be avoided by taking some precautions. Avoid accelerating 100%, at low revs (RPM) whenever there is higher risk, such as when climbing a coastal mountain range (the highest atmospheric pressure and high temperature are aggravating factors); endeavor to supply at more reliable petrol stations, avoiding "miracle" promotions that may indicate fuel adulteration; and if the detonation is detected, drive the vehicle without further efforts to submit it to an inspection by a qualified mechanic.



The octane number is set to a detonation index of a fuel compared to the detonation of a reference fuel consists of a mixture of n-heptane (C7H16), octane as reference zero (0) and 2-2-4-trimethyl pentane (isooctane) as reference hundred (100). For example, a 85 octane fuel indicates that this product has the same tendency to detonate the standard engine tests under the same conditions for a fuel mixture formed of 85% isooctane and 15% n-heptane. There fuels such as gasoline used in competition Formula 1 and ethanol having octane number of 100. The ethanol, for example, has the number equal to 110. To determine these values are used other reference fuel reaching 120 octane. High-octane fuel prevent "off-time" detonations and cheap fuel and low-octane makes it easier. In racing cars, vulnerability to detonations is greater because of the proximity to the motor limits.

And now the good news:
The BE-Fuelsaver (PINOX) can eliminate the detonation phenomenon and increase the life of your engine.

An old Porsche 911, which need to use 98 octane gasoline to prevent the detonation phenomenon, when installing the BE-Fuelsaver (PINOX), now goes with 88 octane gasoline.
