countries, therefore, it has been observed that they are not adapted to the geographical
conditions, an example is the highland area where there are cities that are over 2000 meters
above sea level, which is a determining factor not only for the performance of the vehicle but
also for the incomplete combustion of gasoline.
For this reason it is important that, when performing vibration tests on internal combustion
vehicles, it is important to identify how the quantity in ml of additive together with the type of
gasoline can reduce or increase the vibration level.
Within the steps to follow for the investigation of the article, the fuels and cars with new
technologies that are offered at national level are analyzed, the types of additives offered and by
means of a measuring equipment to analyze the vibrations that these engines demonstrate with
these technologies including the fuels and additives to determine the level of vibration that these
engines can generate at these atmospheric conditions. In the research "Study by means of the
vibration technique of the effects of the pressure variation in the fuel rail on the combustion of
a CRDi engine Model Hyundai Santa Fe 2.0" (Albarracín & Huiñisaca, Estudio mediante la Técnica
de vibraciones de los Efectos de la Variación de Presión en el Riel de Combustible sobre la
Combustión de un Motor CRDi Modelo Hyundai Santa Fe]é 2.0, 2015)The heat power
associated with the fuel that will have a variation when using an additive as a component within
the mixture as a second level, in conjunction with the process that occurs inside the cylinder in
order to quantify the pressure levels in the rail area is analyzed. Thus, it is necessary to analyze
the vibration behavior of a gasoline engine with different technologies, taking into account the
altitude of the city where the study will be carried out.
The vibrations of an Otto cycle vehicle, in the research entitled "Analysis of the vibrations of an
OTTO cycle engine with a gasoline and ethanol-based fuel mixture" (Gutiérrez, Iñiguez, Cadena,
& Santiana, 2017) in which they specify that the behavior of vibrations depends on the quality of
combustion and fuel properties since such vibrations are the consequence of alternating, rotating
and linear movements originating in the combustion process. The research shows that the
defects observed in internal combustion engines are linked to the quality and effects found in
the combustion process, since the latter gives rise to a different vibration pattern.
In the research "Analysis of the degradation and additives of the lubricant of a spark ignition
engine in M1 vehicles within the period of maintainability" (Panchi, 2020) (Panchi, 2020)It is
identified that the additives are important for the operation of the internal combustion engine,
that is why the evaluation of the degradation condition of the additive must have periods of
maintainability in order to guarantee its correct use, since the gasoline of the country is of a
lower quality than that of the countries of origin of the automobiles. Within the proposed
research, it was found that there is a 25% to 32% reduction in the formation of acids related to
oxidation, which notably reduces the capacity of the additive to reduce the vibrations that occur
in the engine area.
In the research "Analysis of vibrations in internal combustion engines by means of ultrasound"
(Cardenas, Cevallos, & Moyano, 2017), the method is established to identify internal shredding
of internal engine components, in order to determine pressurized leaks that minimize the
potential of complete fuel burning, on the other hand the ultrasonic warning allows to recognize
the increase of low frequency vibrations and the progressive increase of temperature.
Thus, when comparing vibrations in internal combustion engines, both rotational balancing
parameters and the construction of the engine used in the vehicle are interpreted. Therefore,
the application of vibration instruments within the analysis of engine performance can improve
the level of vibrations produced by preventive maintenance of the components.
