PURPOSE: An engine cooling control device is provided to control a speed and a driving of a cooling fan automatically by an engine management system according to a signal of a pulse width modulation (PWM) or a signal of a sensor like an engine temperature sensor or a pressure sensor. CONSTITUTION: An engine cooling control device comprises a valve (100), a conductor (200), a second housing, and a first housing (500). The valve is formed in an outer portion of a principal axis, and controls a flow of oil flowing inside an oil seal. The conductor is positioned at a lower part of the valve, and rotates with a cooling fan. The second housing is formed adjacent to a concavo-convex block part of the conductor. A hall sensor (750) is formed inside. In one side, a plastic injection including a connector part housing (610) and a PCB part housing is formed. The hall sensor and a PCB (700) are mounted on the PCB part housing. A cover is formed at an upper part of the PCB. A partition wall is formed inside the PCB part housing. In the first housing, a bobbin in which a coil is reeled is mounted on an inside, and a bearing (400) is formed by passing through a center.

Internal combustion engine

Internal combustion engine

The inventive internal combustion engine is provided with a self-cooling system, i.e. a cooling system is substituted by a self-cooling method consisting in returning the energy which is given up by the external walls of a cylinder during cooling to said cylinder where it works. The self-cooling of a cylinder-piston group is carried out in a cooling chamber formed by the double walls of the cylinder barrels provided with cooling windows connecting said cooling chamber to the cylinder volume which is increased with respect to a combustion chamber and a specified compression rate, thereby making it possible to use a residual gas energy. The self-cooling is carried out by the transmission of a heat energy produced by the cylinder-piston group cooling to a compressed air in the cooling chamber, which subsequently participates in carrying out a useful work. A heat insulating coating prevents from loses of the heat energy of cooling.
