摘要： A cooling structure for an internal combustion engine includes a spacer. The spacer is fitted inside a water jacket which is formed to surround peripheries of a plurality of cylinder bores arranged one after another on a cylinder row line of a cylinder block of the internal combustion engine. A cooling condition of the cylinder bores is controlled by regulating a flow of cooling water in the water jacket by use of the spacer. A fixing member for fixing the spacer inside the water jacket is provided on an inner wall surface of the spacer facing the cylinder bores.

摘要： Volumetric efficiency is reduced in a premixed gaseous fuel engine compared to a premixed liquid fuel engine. An improved method for operating an internal combustion engine and improving volumetric efficiency comprises storing a gaseous fuel in a liquid state; determining a load on the internal combustion engine as a function of engine operating conditions; determining a target temperature for the gaseous fuel that reduces the likelihood of pre-ignition and knock as a function of the load; and controlling the amount of heat transferred to the gaseous fuel to convert it to one of a gas state and a supercritical state, such that the gaseous fuel is introduced into the internal combustion engine at the target temperature.

摘要： An engine cooling device including a water pump, a radiator, an exhaust heat recovery unit, and a coolant circulation circuit for circulating a coolant in these apparatuses includes a flow rate limiting means that limits the flow rate of the coolant that circulates in the exhaust heat recovery unit in the case where a temperature of a sensor element of an A/F sensor, that is disposed downstream of the exhaust heat recovery unit in an exhaust path, is below a preset activation temperature. An extent of opening of a second switching valve is made smaller in the case where the temperature of the sensor element is below the activation temperature than in the case where the temperature is equal to or higher than the activation temperature.
