| description | To improve the combustion of an air-fuel mixture in a main chamber by equally diffusing a flame injected from a sub-chamber in the main chamber by making the flame collide with a guide part arranged at a piston apex face, in a sub-chamber type engine having a jet ignition system.SOLUTION: In a sub-chamber type engine 1 which is partitioned into a main chamber 21 and a sub-chamber 23 by a bulkhead arranged at a cylinder head, and ignites an air-fuel mixture in the main chamber by injecting a flame 35 formed in the sub-chamber 23 into the main chamber from the sub-chamber via a communication path 31 which is formed at the bulkhead, the engine comprises a guide part 33 having such a protrusive shape that the flame injected from the communication path collides with a piston apex face 9a, the guide part is inclined toward a cylinder internal peripheral wall side from the sub-chamber side in a plane view of the piston 9, and a height of the guide part is set to be low as separating from the sub-chamber.SELECTED DRAWING: Figure 2
【課題】本開示の少なくとも一つの実施形態は、ジェット点火システムを備えた副室式エンジンであって、副室から噴出される火炎をピストン頂面に設けられたガイド部に衝突させることによって、主室内において偏りなく分散させて主室内での混合気の燃焼を改善することを目的とする。【解決手段】シリンダヘッドに設けられた隔壁により主室２１と副室２３に区画され、この副室２３内に形成される火炎３５を、隔壁に設けられた連通路３１を介して副室内から主室内に噴出させて主室内の混合気に着火する副室式エンジン１であって、ピストン頂面９ａに連通路から噴出された火炎が衝突するような凸形状のガイド部３３を備え、ガイド部は、ピストン９の平面視において副室側からシリンダ内周壁側へ向かって傾斜して延在し、ガイド部の高さは、副室から遠ざかるにつれて低くなる。【選択図】図２ |
