Abstract: The engine generator set has an internal combustion engine and an alternator in a main compartment. Two separate cooling air streams independently cool the internal combustion engine and alternator. The independent air streams are then intermixed in the main compartment and used to cool the engine exhaust system and gases. Heat sensitive components are segregated from the heat generating components. Cooling air is drawn over the heat sensitive components maintaining them at nearly ambient temperature.

Abstract: The air-fuel mixture produced by a carburetor is controlled by an apparatus that includes a choke valve located in a passage of the carburetor. A solenoid with a moveable plunger rod coupled to move the choke valve between extreme open and closed positions, and having a stop fixed to the plunger rod. A bimetallic element changes shape in response to changes in temperature, wherein below a given temperature the bimetallic element engages the stop thereby restricting movement of the plunger rod and preventing the choke valve from reaching the extreme open position. Above the given temperature the bimetallic element changes shape to avoid engaging the stop thereby allowing the choke valve to reach the extreme open position. A foil electric heater is mounted on a surface of the bimetallic element to match the shape of the element to the desired performance characteristic of the engine.

Abstract: An enclosure for an engine and a generator which is adapted to be positioned in the front of a motor vehicle and adjacent an inlet for the coolng air of the vehicle engine. A housing encloses both an engine and a generator, and there are separate air inlet openings and air outlets for the engine and the generator. In a preferred manner the air outlet duct for the engine extends to the outside of a motor vehicle and laterally thereof with the air outlet adapted to accommodate an exhaust pipe for a generator engine. Also preferably the air inlet and outlet for the generator are disposed at a 90 degree angle from each other.
