Problem. The features of the design and operation of piston engines in general aviation are
considered. Comparative analysis of design features and parameters of automobile and aircraft engines is carried out. It is shown that car engines, despite the high technical level achieved at the beginning of the 21st century, do not technically meet aviation requirements. At the same time, engines
created on the basis of automobiles through their deep modernization meet aviation requirements,
however, modernization and adaptation of a standard automobile engine to aviation use in terms of
costs compared to the creation of a new engine. Purpose. Carry out research on the failure of automobile engines used in light aviation. Methodology. Rough calculations of the service life of an automobile engine were made based on standard driving tests and a flight plan. According to the results of
calculations, it has been established that the resource of a standard automobile engine in aviation is
reduced many times due to prolonged operation at high loads and rotational speed that are not characteristic of ordinary automotive applications. Results. Experimental data have been obtained on the
actual failure of standard automobile engines in aviation during the operating time, significantly less
resource of aircraft engines of well-known brands. Based on the results of the study, it was concluded
that the use of general aviation automobile engines is economically ineffective due to a short resource
and insufficient reliability. Originality. Modern automobile engines, despite their technical perfection,
cannot be used in aviation, since they do not correspond to aviation operating conditions. At the same
time, adaptation of automobile engines to aviation applications is possible, but requires significant
design changes, which makes their single use, as a rule, technically impractical and economically ineffective. Practical value. Due to the fact that saving on an aircraft engine is unacceptable from the
point of view of flight safety, the aviation use of automobile engines without special modernization
carries excessive risks of failures and their consequences. As a result, serial aircraft engines Lycoming, Continental, Jabiru, ULPower, Rotax, Limbach and others have virtually no alternative in
general aviation
