摘要： An engine includes a cylinder liner. The cylinder liner includes an interior wall, an exterior wall, and a thermoelectric element disposed therebetween. The interior wall forms a cylinder bore forming part of a combustion chamber. The exterior wall is positioned adjacent a coolant jacket. The thermoelectric element is operable to generate an electric current in response to a temperature gradient between the interior wall, which is exposed to the high temperatures of the combustion chamber, and the exterior wall, which is exposed to the cooler temperatures of a coolant in the coolant jacket. An electric current in a circuit of the thermoelectric element may be controlled to affect a cylinder wall temperature. The circuit of the thermoelectric element may be opened, and the voltage of the thermoelectric element may be measured and used to calculate the cylinder wall temperature.

摘要： A cooling system is provided for a vehicle having an engine. The cooling system includes a pair of heat exchangers, such as an oil cooler and a charge air cooler, laterally spaced apart from each other and located in front of a front end of the engine. A pair of blower units are in front of the coolers and blow cooling air rearwardly therethrough. A pair of duct units are located above the engine and to the rear of the coolers. Each duct unit includes a forward opening inlet receiving warmed air from the corresponding cooler, an upwardly opening outlet and a hollow housing extending from the inlet to the outlet. The outlets are spaced laterally apart from each other. A radiator is positioned above the duct unit housings and forward of the outlets. A set of radiator fans blow air upwardly through the radiator and are positioned between the radiator and the duct housings.

摘要： Cylinder arrangement (1) and method for cooling the cylinder arrangement (1) addresses a solution with which the heat transfer from a combustion chamber (6) of an internal combustion engine located in a cylinder liner (2) of the cylinder arrangement (1) into a region (7) surrounding the cylinder liner (2), such as a cylinder block or crankcase, is controlled in a temperature-dependent manner. Arrangement solves said problem by providing a jacket (9), the expansion of which changes depending on temperature, arranged between the cylinder liner (2) and the region (7) surrounding the cylinder liner (2). The method uses the cylinder liner (2) with a jacket (9), expands depending on temperature and surrounds the cylinder liner (2); jacket (9) forms a gap (10) between jacket (9) and region (7) in a first temperature range; jacket (9) forms no gap (10) between jacket (9) and region (7) in a second temperature range.

摘要： In a spark-ignition internal combustion engine in which a protrusion including an intake-side inclined surface and an exhaust-side inclined surface is formed on a top surface of a piston, and a cavity is formed in the protrusion at a position associated with a spark plug, the intake-side inclined surface and the exhaust-side inclined surface are formed in such a way that a ratio of a length of the exhaust-side inclined surface with respect to a length of the intake-side inclined surface is 1.25 or larger in a cross section passing through a center axis of the piston and orthogonal to an axis direction of a crankshaft.
