摘要
An internal combustion engine (100) including a low thermal capacity, low thermal conductivity insulating liner (114) is provided. The insulating liner (114) may be positioned to line the combustion chamber (113) and a portion of the cylinder wall (106). The insulating liner (114) may comprise a high aspect morphology sintered ceramic material and may further include a surface coating. The internal combustion engine (100) may be a four-stroke diesel engine with variable valve timing operating using an asymmetric cycle. Through the asymmetric cycle and insulative properties of the insulating liner (114), the heat loss of the disclosed internal combustion engine (100) is significantly less than that of a similar conventional internal combustion engine, resulting in significant efficiency improvements.
