Изобретение относитс к способам определени суммарного зазора в кривошппно-шатунном механизме при диагностике двигател внутреннего сгорани без его разборки.The invention relates to methods for determining the total clearance in a crank-drive-connecting rod mechanism in the diagnosis of an internal combustion engine without disassembling it.
Известны способы определени суммарного зазора в кривошипно-шатунном механизме внутри цилиндра неразобранного двигател внутреннего сгорани путем измерени перемещени поршн при установке последнего в верхнее мертвое положение и создани давлени или разрежени в цилиндре.Methods are known for determining the total clearance in a crank mechanism within a cylinder of an internal combustion engine that has not been disassembled by measuring the displacement of the piston when the latter is in the upper dead position and creating pressure or vacuum in the cylinder.
При таком способе определени суммарного зазора в кривошипно-шатунном механизме перемещение вала в коренных подшипниках происходит с перекосом и, кроме того, ограничиваетс подшипником, не относ щимс к измер емому цилиндру. Измерение перемещени поршн измерительной ножкой индикатора возможно только в том случае, когда ось форсунки расположена параллельно оси цилиндра , что во многих современных конструкци х двигателей не имеет места.With this method of determining the total clearance in the crank mechanism, the movement of the shaft in the main bearings is skewed and, in addition, is limited by a bearing that is not related to the cylinder to be measured. Measuring the movement of the piston with the measuring foot of the indicator is possible only when the nozzle axis is parallel to the axis of the cylinder, which is not the case in many modern engine designs.
Цель изобретени - придание способу большей универсальности и повышение точности определени зазора.The purpose of the invention is to make the method more versatile and improve the accuracy of the clearance.
Цель достигаетс тем, что измерение перемещени поршн производ т при прижатом к коренным подшипникам коленчатом вале, дл чего в цилиндры, ближайшие к тому, в котором осуществл ют измерени , подают сжатыйThe goal is achieved by measuring the displacement of the piston with the crankshaft pressed against the main bearings, for which a compressed air is supplied to the cylinders closest to the one in which the measurements are made.
воздух через открытые выпускные клапаны и выпускной коллектор. Перемещение поршн регистрируют с помощью опущенного на днище поршн при отжатых пружинах впускного клапана, причем перемещение поршн осуществл ют многократно в противоположных направлени х , нагнета в цилиндр или отсасыва из него воздух через открытый впускной клапан и впускной коллектор.air through open exhaust valves and exhaust manifold. Piston movement is recorded using an intake valve lowered at the bottom of the piston with the springs pressed, the piston moving repeatedly in opposite directions, forcing air into or out of the cylinder through the open intake valve and intake manifold.
