Engine Intake Thermostat Using Turbocharger
The present invention relates to an intake temperature control apparatus for an engine, and more particularly, an engine for controlling an intake temperature by mounting a temperature sensor on an intake manifold and increasing or decreasing a heat exchange amount by a turbocharger based on a signal from the temperature sensor. It relates to an intake air temperature control device.
Background Art A turbocharger that uses heat of exhaust gas to increase the temperature of air sucked into an engine has been developed in the past. This is to perform heat exchange with the exhaust gas when the air is sucked into the engine so that the suction air is heated.
However, such a device has a problem that the suction temperature cannot be adjusted to the target temperature because the suction temperature always depends only on the exhaust gas.
The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide an engine intake temperature control apparatus using a turbocharger that can adjust the temperature of the intake air to a target temperature required by the engine.
Engine intake temperature control apparatus using a turbocharger of the present invention for achieving the above object is a temperature sensor installed on the intake manifold, a magnetic clutch fan installed on the air suction pipe, a relay for supplying power to the magnetic clutch fan, the relay, It characterized in that it comprises a controller for controlling the relay to the target flow temperature by the signal from the temperature sensor.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is a block diagram of an engine intake temperature control apparatus using the turbocharger of the present invention.
As shown, the engine intake temperature control apparatus using the turbocharger of the present invention is powered by a temperature sensor (1) installed on the intake manifold, a magnetic clutch fan (2) installed on the air suction pipe, the magnetic clutch fan (2) And a controller (4) for controlling the relay (3) so as to reach a target intake temperature by a signal from the temperature sensor (1).
Engine intake temperature control apparatus using the turbocharger of the present invention acts as follows.
The air enters the engine cylinder via the turbocharger, through the turbocharger 5 installed on the suction passage. The exhaust gas pressure is applied to the turbocharger 5.
The intake air is thus warmed by the turbocharger 5. However, when the magnetic clutch fan 2 is operated, the temperature of the suction is further warmed up. Therefore, the friction clutch fan 2 can be turned on and off to adjust the intake air temperature.
The controller 4 measures the temperature of the intake air entering the current cylinder by the signal from the temperature sensor 1, and controls the relay 3 to supply power to the friction clutch fan 2 when the target temperature is not reached. When the friction clutch fan 2 is operated, the sucked air is greatly heated by the turbocharger 5. Therefore, the temperature of intake air rises.
When the temperature of the intake air reaches the target value, the controller 4 controls the relay 3 to cut off the power supply to the friction clutch fan 2. The temperature of the intake air then falls.
The present invention controls the temperature of the intake air by repeating this action.
As described above, the engine intake temperature control apparatus using the turbocharger of the present invention can adjust the temperature of intake air to a target temperature required by the engine, thereby improving combustion performance and thereby improving fuel efficiency.
It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
