Abstract

Изобретение предназначено дл  повышени  качества холодной приработки двигателей внутреннего сгорани . Коленвал двигател  прокручивают от внешнего привода, увеличива  частоту вращени  по колебательному закону. При этом после каждого полупериода колебаний частоты вращени  его направление измен ют на противоположное.The invention is intended to improve the quality of cold burn-in of internal combustion engines. The crankshaft of the engine is rotated from an external drive, increasing the speed of rotation according to the oscillatory law. At the same time, after each half-period of oscillation of the rotation frequency, its direction is reversed.

The crankshaft of the engine is rotated from an external drive, increasing the frequency of rotation according to the oscillating law. At the same time, after each half-period of oscillation of the rotation frequency, its direction is reversed.

Изобретение относитс  к машиностроению и может быть использовано при приработке двигателей внутреннего сгорани  после их изготовлени  или ремонта .The invention relates to mechanical engineering and can be used in the run-in of internal combustion engines after their manufacture or repair.

Цель изобретени  - повышение качества холодной приработки.The purpose of the invention is to improve the quality of cold running-in.

Способ осуществл етс  следующим образом .The method is carried out as follows.

Двигатель устанавливают на обкаточный стенд и подключают к магистрал м централизованного масла и водоснабжени . Прокручивают коленчатый вал двигател , увеличива  частоту вращени  по колебательному закону, причем одинThe engine is installed on the rolling stand and connected to the main line of the centralized oil and water supply. The crankshaft of the engine is rotated, increasing the rotational speed according to the oscillating law, and one

полупериод колебани  частоты вращают коленчатый вал в одну сторону, а другой полупериод - в другую.half-cycle frequency rotates the crankshaft in one direction, and the other half-cycle - in the other.
