ENGINE COMBUSTION CHAMBER STRUCTURE, AND INNER WALL STRUCTURE OF FLOW PATH |
摘要 |
<p>Provided is an engine combustion chamber structure wherein the thermal efficiency of an engine and fuel consumption are improved. Also provided is an inner wall structure for a flow path through which exhaust gas or intake gas of the engine passes. An engine combustion engine structure is provided with a heat-insulating member (1) on the inner wall of an engine constituent member (21) which constitutes an engine combustion chamber, the heat-insulating member (1) containing a heat-insulating porous layer (3) formed from ceramics, and a surface dense layer (2) formed on the surface of the heat-insulating porous layer (3) and formed from ceramics. The surface dense layer (2) of the heat-insulating member (1) has an open porosity of 5% or less, and preferably the heat-insulating porous layer (3) has a larger open porosity than the open porosity of the surface dense layer (2).</p> |
