Abstract

FIELD: engine engineering. SUBSTANCE: combustion chamber 7 is positioned in cylinders 2 between pistons 1. The cylinders arranged in plane perpendicular to their axes are shifted one with respect the other to define at least two C-shaped zones. The magnitude of the shifting is (0.3-0.7)D, where D is diameter of the cylinder. Valves 6 of the valve gearing are arranged in C-shaped zones and their ases are parallel. Turns are absent on flow of the mixture from the valve to combustion chamber 7. This permits hydraulic resistance to be minimum and results in conserving the block coefficient of combustion chamber 7 at a level inherent to the engines with suspended valves. EFFECT: enhanced reliability. 2 dwg

Description

Изобретение относится к области машиностроения и предназначено для использования в двигателях внутреннего сгорания. The invention relates to mechanical engineering and is intended for use in internal combustion engines.

Целью изобретения является повышение надежности двигателя. The aim of the invention is to increase engine reliability.

На фиг. 1 изображен схематический разрез двигателя; на фиг.2 разрез А-А на фиг.1. In FIG. 1 is a schematic sectional view of an engine; figure 2 section aa in figure 1.

Двигатель внутреннего сгорания содержит по крайней мере два поршня 1, размещенных в цилиндрах 2, при этом каждый поршень кинематически, посредством, например, кривошипно-шатунного механизма 3, связан с соответствующим выводным валом 4. Серповидные торцовые поверхности 5 цилиндров содержат клапаны 6 газораспределения, обеспечивающие газообмен в камере сгорания 7, размещенной в цилиндрах между поршнями. Клапаны непосредственно связаны с кулачками 8, имеющими кинематический привод посредством, например, шестерен 9 от вала. The internal combustion engine contains at least two pistons 1 located in the cylinders 2, each piston kinematically, for example, by means of a crank mechanism 3, connected to the corresponding output shaft 4. Crescent end surfaces 5 of the cylinders contain gas distribution valves 6, which provide gas exchange in the combustion chamber 7, located in the cylinders between the pistons. The valves are directly connected to the cams 8 having a kinematic drive through, for example, gears 9 from the shaft.

В четырехтактном цикле двигатель работает следующим образом. In a four-cycle cycle, the engine operates as follows.

В такте наполнения поршни 1, приводимые в движение от вала 4, посредством кривошипно-шатунного механизма 3 расходятся, одновременно клапаны 6 газораспределения под действием кулачка 8 перепускают в камеру сгорания 7 топливно-воздушную смесь. In the filling stroke, the pistons 1, driven by the shaft 4, diverge by means of the crank mechanism 3, at the same time the gas distribution valves 6, by the action of the cam 8, transfer the fuel-air mixture to the combustion chamber 7.

Отсутствие поворотов в движении смеси от клапана 6 к камере сгорания 7 обеспечивает минимальное гидравлическое сопротивление, что позволяет сохранить коэффициент наполнения камеры сгорания на уровне двигателей с подвесными клапанами. В такте выхлопа поршни 1, приводимые в движение от вала 4 посредством кривошипно-шатунного механизма 3, сходятся, вытесняя при этом из камеры сгорания 7 выхлопные газы через открытые клапаны 6 газораспределения. Открытие клапана осуществляется непосредственно от кулачка 8, приводимого во вращение валом 4 через шестерни 9. Отсутствие поворотов в движении выхлопных газов из камеры сгорания 7 к клапанам 6 обеспечивает минимальное гидравлическое сопротивление, что улучшает очистку камеры сгорания от выхлопных газов. The absence of turns in the movement of the mixture from valve 6 to the combustion chamber 7 provides minimal hydraulic resistance, which allows to maintain the filling factor of the combustion chamber at the level of engines with outboard valves. In the exhaust stroke, the pistons 1, driven by the shaft 4 by means of a crank mechanism 3, converge, displacing the exhaust gases from the combustion chamber 7 through the open valve timing 6. The valve is opened directly from the cam 8, driven by a shaft 4 through gears 9. The absence of turns in the movement of exhaust gases from the combustion chamber 7 to the valves 6 provides minimal hydraulic resistance, which improves the cleaning of the combustion chamber from exhaust gases.
