    Abstract: A combustion control apparatus for an engine having a variable valve timing mechanism capable of varying valve timings of an exhaust valve and an intake valve establishes a combustion mode to either of following three modes, a four-cycle compression ignition combustion mode at a low and medium load area, a two-cycle spark ignition combustion mode at a high load area, and a four-cycle spark ignition combustion mode at a high speed area. When the combustion mode is established to the compression ignition combustion mode, the apparatus establishes the valve timings of the exhaust and intake valves so as to form a negative overlap period in which both exhaust and intake valves concurrently close in the neighborhood of the exhaust top dead center (TDC).

    Abstract: In an internal combustion engine, a combustion chamber is provided in a cylinder head on one side of a partition wall, and a heat-insulating layer is provided in the cylinder head on the other side of the partition wall. Cooling passages are provided in a plurality of regions provided with different heat loads in the partition wall, respectively. The flow rate of a cooling medium is set, so that the flow rate in the cooling passage existing in the region of the larger heat load is larger than that in the cooling passage existing in the region of the smaller heat load. Thus, the temperature of an exhaust gas can be maintained at a high level by maintaining the combustion chamber at a high temperature.

    Abstract translation: 在内燃机中，在分隔壁的一侧的气缸盖中设置燃烧室，在隔壁的另一侧设置有隔热层。 冷却通道分别设置在分隔壁上设置有不同热负荷的多个区域中。 设定冷却介质的流量，使得存在于较大热负荷区域的冷却通道中的流量大于存在于较小热负荷区域的冷却通路中的流量。 因此，通过将燃烧室维持在高温，能够将废气的温度维持在高水平。
