Title: Intake device for engine
Inventor: KONDO MITSUNORI
IPC: F02B31/02
Filed: 1995-03-28
Abstract: PURPOSE: To obtain an intake device for an engine of a simple structure, by which a suitable swirl can be generated according to the engine rotating speed. CONSTITUTION: In an intake two-valve type diesel engine DE, first intake ports 3a-3d are taken as a high swirl port, and on the other hand, second intake ports 4a-4d are taken as a low swirl port. The tuning point of the resonance effect on the first intake port side is set in a low rotation region, and the tuning point of the resonance effect on the second intake port side is set in a high rotation region. Thus, in the low rotation region, the intake air inflow on the first intake port side is made larger by the resonance effect on the first intake port side, so that a strong swirl is generated in combustion chambers 2a-2d so as to heighten combustibility of fuel. On the other hand, in the high rotation region, the intake air inflow on the second intake port side is made larger by the resonance effect on the second intake port side, so that a strong swirl is not generated in a cylinder so as to sufficiently heighten the charging efficiency.

Abstract: PURPOSE: To prevent thermal deformation of the subject pipe by filling a low-temperature-melting alloy in a gap between the inside of the hole of the main body of an axis and the outside of a heat pipe in the subject axis with the heat pipe built in the main body of the axis.  
     CONSTITUTION: A low-temperature-melted alloy 11 is filled in a gap formed by the inside of the hole 5 of the main body 4 of an axis and the outside of a heat pipe 6.

A material whose melting point is, for instance, 70W100°C is used as the alloy 11, and by using such material as having almost the same thermal conductivity with that of the main body 4 of the axis, the thermal resistance from the main body 4 toward the heat pipe 6 is made to be almost equal, even when the heat pipe is built eccentrically in the main body 4 of the axis. Accordingly, even when the heat pipe is eccentric in the main body of the axis, the thermal resistance in the direction of diameter becomes uniform, and thereby the difference in the distribution of temperature in the circumferential direction is eliminated and the deformation of the pipe due to the difference in the thermal expansions of the two can be prevented.
