Способ диагностики двигателя внутреннего сгорания путем определения зазоров в его сопряжениях по интервалу времени между стробирующим и вибрационным импульсами от проверяемого сопряжения, причем вибрационные импульсы выделяются на одной из резонансных частот виброакустического канала, соответствующего проверяемому сопряжению, отличающийся тем, что диагностика осуществляется на неработающем двигателе путем создания колебаний в исследуемом сопряжении от постороннего источника (вибратора) при изменении частоты колебания до появления эффекта резонанса.A method for diagnosing an internal combustion engine by determining the gaps in its mates according to the time interval between the strobe and vibration pulses from the tested pair, moreover, vibration pulses are emitted at one of the resonant frequencies of the vibro-acoustic channel corresponding to the tested pair, characterized in that the diagnosis is carried out on an idle engine by creating oscillations in the studied conjugation from an external source (vibrator) when the oscillation frequency changes until Ia resonance effect.
