Description
Изобретение относитс к машиностроению , а именно к двигателестроению в частности к выполнению камер сгорани в двигател х внутреннего сг рани .. . Известны двигатели внутреннего сгорани , содержащие камеру сгорани в поршне, выполненную с наклонной образующей, соединенную горловиной с надпоршневым пространством и отсе каемую при положении поршн в верхне мертвой точке вытеснителем, размещен ным в головке цилиндров и снабженным форсункой, расположенной соосно с горловиной 1 . Однако распылитель топливной форсунки работает в т желых температурных услови х, 4ТО приводит к зависанию иглы распылител и выходу из стр топливной форсунки. Кроме того, известные двигатели имеют плохое качество распцла топлива , вследствие несоответстви длины топливного факела рассто нию от распылител форсунки до поверхности камеры сгорани , что приводит к неполному сгоранию, ухудшению экономичности и повышению дымности особенно в малоразмерных быстроходных дизел х. Цель изобретени - улучшение экономичности . Дл достижени дели вытеснитель снабжен полостью с конусной образующей , угол наклона которой равен углу наклона образующей камеры сгорани , а меньшее основание равно диаметру форсунки, причем высота полости выполнена равной 1,0-1,2 высоты вытеснител . При этом, форсунка двигател может быть установлена в конусной полости на уровне ее меньшего основани . На чертеже представлен двигатель, разрез через камеру сгорани . Двигатель содержит камеру 1 сгорани , выполненную с наклоннрй образующей 2 и снабженную горловиной 3 соедин ющей ее с надпоршневым простFIELD OF THE INVENTION The invention relates to mechanical engineering, in particular to engine-building, in particular, to the implementation of combustion chambers in internal combustion engines. The internal combustion engines are known that contain a combustion chamber in a piston made with an inclined generatrix, connected by a throat to the over piston space and cut off when the piston is in dead center by a displacer located in the cylinder head and fitted with a nozzle located coaxially with the throat 1. However, the fuel injector dispenser operates under severe temperature conditions, 4TO causes the atomizer needle to hang and exit the fuel injector page. In addition, known engines have poor fuel quality due to the inconsistency of the length of the fuel plume from the nozzle to the surface of the combustion chamber, which leads to incomplete combustion, poor fuel economy and increased opacity, especially in small high-speed diesel engines. The purpose of the invention is to improve efficiency. To achieve the task, the displacer is provided with a cavity with a conical generatrix whose angle of inclination is equal to the inclination angle of the generatrix of the combustion chamber, and the smaller base is equal to the diameter of the nozzle, the cavity height being equal to 1.0-1.2 of the displacer height. In this case, the engine nozzle can be installed in the conical cavity at the level of its smaller base. The drawing shows the engine, a cut through the combustion chamber. The engine contains a combustion chamber 1, made with a sloping generatrix 2 and provided with a neck 3 connecting it with a piston shaft
