摘要： A device for electronically controlling the intake air temperature of an internal combustion engine, featuring a temperature sensor in the clean air space of the filter, the signal from the sensor controlling an electromagnetically driven oscillator pump whose vacuum output adjusts the flapper of an air flow proportioning valve by means of a pneumatic actuator, until the correct ratio of cold and preheated raw air is admitted into the intake system for the establishment of an optimal combustion air temperature. An automatic lowering of this temperature under full-load operation is achieved by utilizing the negative pressure in the air intake manifold as a control means to shift the oscillating armature of the oscillator pump away from its maximum output position. In an air intake system for fuel-injected engines, a similar result is achieved by means of an air flow sensor whose output signal is superimposed on the control signal from the temperature sensor.

摘要： An intake air temperature control device for mixture-compressing internal combustion engines having an inlet flapper proportioning the flows of cold and preheated raw air into a duct junction and into raw air mixing duct, the flapper-adjusting wax thermostat being arranged inside a thermostat chamber into which branch flows of cold and preheated raw air are admitted through two calibrated branch inlets. A narrow annular gap through which the combined branch flows must pass assures an integrated response of the thermostat to changing temperatures and air intake speeds. A lost-motion drive connection and a biasing member produce a full-load correction of the adjusted temperature. The flapper drive members may have valve edges which cooperate with the calibrated branch inlets to open and close the latter.

摘要： A device for automatically regulating the intake air temperature of a carburetor-equipped internal combustion engine whose air intake system includes a flow proportioning pivotable flapper in a duct junction admitting cold raw air and/or preheated raw air to the air intake filter, depending on the ambient temperature, the flapper position being controlled by a pneumatic membrane actuator receiving negative pressure from the engine intake manifold, via a vacuum line with a thermostat-controlled pressure relief valve which reads the temperature of the raw air mixture. In the cold air intake duct is arranged a temperature-responsive unit, in the form of either a wax thermostat or a bimetallic spiral and disc cam, which serves as a position-adjustable stop thereby preventing the flapper from completely closing the warm air intake duct, when the engine takes in cold air, operating at full load.
