MEANS FOR CONTROLLING THE TEMPERATURE OF THE INTAKE AIR IN AN INTERNAL COMBUSTION ENGINE

... 1426380 Intake air temperature control for I C engines AUDI NSU AUTO UNION AG 7 Nov 1973 [10 Nov 1972] 51569/73 Heading F1B The temperature of air fed to an I.C. engine is determined by controlling the proportions of heated air fed through a pipe 6 and cold air fed through a pipe 5 to a mixing chamber 4 by means of a flap 7 responsive to a temperature sensing device 15 in a liquid coolant or lubricant circuit of the engine. While the coolant or lubricant is below its normal operating temperature, a slide 14 is in the position shown in Fig. 1, so that manifold vacuum is communicated by pipes 11, 12 to an actuator 8 causing flap 7 to cut off cold air and allow heated air to reach the engine. At normal operating temperature, slide 14 rises and flap 7 moves to the position shown in broken lines to cut off the heated air supply and allow cold air to pass to the engine. In Fig. 2 (not shown), the temperature sensing device 15 acts directly on the flap 7.

APPARATUS FOR REGULATING THE TEMPERATURE OF I.C. ENGINE INTAKE AIR

Temperature responsive control devices

In a device for controlling the temperature of the intake air to an internal combustion engine, the piston of a hydraulic cylinder controls the setting of a damper between the warm-air intake and the cold-air intake. A sensor body in the mixed-air duct communicates, via a hydraulic conduit, with the cylinder. The sensor body is filled above a free piston with an expansion medium of higher coefficient of thermal expansion than the hydraulic medium on the opposite side of the free piston. By allowing the temperature in the engine compartment, for example, to determine the temperature of the hydraulic conduit, the control interval is displaced so that the temperature of the intake air is higher when the engine is cold than when it is warm.

Adjusting inlet air temp. of IC engine - by mixing cold and hot air flows as function of engine parameter

The air intake manifold is divided into two sections before the filter. One section (21) receives cold air and the other (22) receives heated air. A diverter valve (20) controls the proportion of air from each supply. This valve is operated by a mechanical linkage from a diaphragm (23). The air passes through the filter (19) and over two sensors (30 and 31), which have bimetal strips controlling valves opening at different angles, before passing the throttle valve (17). A switch (26) is operated by a diaphragm (33) which senses the manifold air pressure so that one of the sensors is switched in circuit to control manifold pressure applied to the diaphragm (23). Thus manifold pressure controls the proportion of cold and hot air passed to the manifold.

Thermostatic valves for intake air temperature compensation for internal combustion engines

Inlet air temperature control for automobile engine

Ambient inlet air and preheated inlet air are supplied to an internal combustion engine in proportions controlled by a proportioning valve to determine the temperature of the resultant inlet air mixture. Means responsive to the inlet air temperature downstream of the proportioning valve cooperate with an engine vacuum source to apply a temperature modulated motor actuating pressure to a vacuum motor, which in turn operates the proportioning valve to increase the proportion of ambient air as the inlet air mixture approaches a predetermined engine operating temperature. A restricted temperature responsive one-way check valve means retards the rate of flow of motor actuating pressure to the motor when the inlet air temperature downstream of the proportioning valve is above a predetermined minimum, prevents said flow entirely when the inlet air temperature is below said predetermined minimum, and enables the reverse flow of pressure freely from the motor regardless of temperature.

INTAKE AIR MIXER OF AN INTERNAL COMBUSTION ENGINE

Device for electronically controlling the intake air temperature of an internal combustion engine

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.
