Embodiment Construction

[0041] refer to figure 1 , the circuit for supplying air to cylinders 100 of a turbocharged internal combustion engine of a motor vehicle can be seen. The air sucked in from the outside passes into the air filter 101 and is then compressed by the compressor 102 of the turbocompressor which sends the air into the double restrictor forming the subject of the present invention. The body 1 of the double restrictor has an inlet channel 2 through which the air from the compressor passes, and two outlet channels 3 and 4 . The restrictor receives commands for controlling the air between these two channels from a controller 103 , called an electronic control unit (ECU). These commands are executed in the form of a displacement of the flaps, which more or less close the channel 3 under the action of an electric actuator motor (not shown) incorporated in the body of the double restrictor and a suitable kinematic system and 4. A heat exchanger or cooler 5 is mounted on one of these cha...

Abstract

The invention relates to a device for dosing inlet fluid in an engine and for regulating the temperature thereof, comprising a dosing body wherein a first and a second circulation channel are arranged. First (10) and second (20) movable flow dosage flaps are arranged in said circulation channels. Said dosing body additionally comprises an actuator motor and a kinematic capable of actuating the first and / or the second flap, and said device additionally comprises first and second tubes, at least one of the tubes comprising a means for modifying the temperature of the fluid, characterised in that the kinematic is shaped so as to position at rest, if flap actuation is lost, the flap (10) of the cool channel being then in a fully open position and the flap (20) of the hot channel being then in a fully closed position.

Description

technical field [0001] The invention relates to the field of automobiles, and more particularly the field of engine supply equipment. Background technique [0002] A motor vehicle heat engine includes a combustion chamber, typically formed by a plurality of cylinders, in which a mixture of fuel and air is combusted to produce engine work. [0003] In some known arrangements the incoming fluid flowing, including the air required for the operation of the engine, is divided between the two conduits. One of the ducts carries means for cooling the fluid, while the other duct does not include such means. These two ducts meet each other at the inlet of the engine. The control may thus be based on whether more fluid is supplied via passages through the cooler (called cooling passages) or via passages bypassing the cooler (known as bypass passages or non-cooling passages) before the fluid is introduced into the cylinders while changing the fluid temperature. The control means thu...
