(55) СПОСОБ ОЦЕНКИ ТЕХНИЧЕСКОГО СОСТОЯНИЯ ДВИГАТЕЛЯ ВНУТРЕННЕГО СГОРАНИЯ(55) METHOD FOR ESTIMATING THE TECHNICAL CONDITION OF INTERNAL COMBUSTION ENGINE
1one
Изобретение относитс к машиностроению, точнее, к диагностике технического состо ни двигателей внутреннего сгорани (ДВС).The invention relates to mechanical engineering, more precisely, to the diagnosis of the technical condition of internal combustion engines (ICE).
Известен способ оценки технического состо ни ДВС по величине зазора в сопр жении кривошшшо-шатунного механизма путем измерени положени поршн в верхней мертвой точке 1.There is a method for evaluating the technical condition of an internal combustion engine by the size of the gap in conjunction with the crank mechanism by measuring the position of the piston in the top dead center 1.
Однако сушаствзоощий способ обладает низкой достоверностью.However, the dry process has low reliability.
Цель изобретени - повышение достоверности оценки.The purpose of the invention is to increase the reliability of the assessment.
Поставленна цель достигаетс тем, что измерение положений поршн производ т при рабочем и нерабочем тактах и по их разнице суд т о техническом состо нии двигател .The goal is achieved by measuring the positions of the pistons with working and non-working strokes and judging by their difference the technical condition of the engine is judged.
При нерабочем такте (например, такте выпуска ) работающего двигател на поршень и другие детали кривошипно-шатунного механизма (КШМ), приближающиес к верхней мертвой точке (ВМТ), действует сила инерции , под действием которой поршень максимально удал етс от оси коленчатого валаWith the off stroke (for example, the exhaust stroke) of a running engine, the inertia force acts on the piston and other parts of the crank-connecting rod mechanism, approaching the top dead center (TDC), under the action of which the piston is as far as possible away from the crankshaft axis
и выбирает при этом зазоры с одной стороны сопр жений КШМ.and, at the same time, selects gaps on one side of CMR connectors.
При рабочем такте (такте сгорани рабочей смеси) на поршень со стороны расшир ющихс газов действует сила противоположного направлени . Ввиду того, что зажигание смеси происходит до прохождени поршнем ВМТ, в момент прохождени поршнем ВМТ на него со стороны газов действует сила, превьш1ающа действующие силы инерции.During the working stroke (combustion stroke), the piston from the side of the expanding gases is acted upon by the force of the opposite direction. Due to the fact that the ignition of the mixture takes place before the passage of the TDC piston, at the time of the passage of the piston of the TDC, a force exerts on it from the gases that exceeds the effective inertia forces.
Разница в положени х поршн при нерабочем и рабочем тактах в ВМТ равна удвоенному значению зазоров в сопр жени х КШМ. Регистраци положений поршн работающего двигател может бьггь осуществлена любым известным способом с использованием запнсьшающих устрюйств.The difference in the positions of the piston with the non-working and working cycles in the TDC is equal to twice the value of the gaps in the crank end mounts. The registration of the piston positions of a running engine can be carried out by any known method using a portable device.
Предлагаемый способ применительно к карбюраторному двигателю по сн етс чертежом.The proposed method as applied to a carburetor engine is illustrated in the drawing.
Дл осуществлени способа примен етс специальна свеча 1 зажигани ; с измерительной пластиной 2, к кбторой креп тс тензодатчики 3, включенные в схему регистрирующего прибора 4.For the implementation of the method, a special ignition plug 1 is used; With the measuring plate 2, the strain gages 3, included in the chart of the recording device 4, are attached to the container.
