Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
An enclosure for an engine and a generator, the enclosure adapted to be positioned in the front of a motor vehicle and adjacent an inlet for the cooling air of the vehicle engine, the enclosure comprising: a housing enclosing both an engine and a generator; at least one air inlet opening and an air outlet opening spaced from said air inlet; an air outlet duct in fluid communication with the air outlet and adapted to extend to the outside of a motor vehicle, the air outlet constructed and arranged to accommodate an exhaust pipe for a generator engine; whereby the same duct accommodates both air exiting from the enclosure and the exhaust pipe so that the exiting air assists in cooling the exhaust pipe.
Claim 2
Dependent Claim
124 words
An enclosure for an engine and a generator, the enclosure adapted to be positioned in the front of a motor vehicle and adjacent an inlet for the cooling air of the vehicle engine, the enclosure comprising: a housing enclosing both an engine and a generator; at least one air inlet opening and an air outlet opening spaced from said air inlet; an air outlet duct in fluid communication with the air outlet and adapted to extend to the outside of a motor vehicle, the air outlet constructed and arranged to accommodate an exhaust pipe for a generator engine; whereby the same duct accommodates both air exiting from the enclosure and the exhaust pipe so that the exiting air assists in cooling the exhaust pipe.
Claim 3
Dependent Claim
20 words
The enclosure as defined in claim 1 wherein the air outlet duct is positioned transversely to the air inlet opening.
Claim 4
Dependent Claim
30 words

Claim 5
Dependent Claim
23 words
The enclosure as defined in claim 1 further including a separate air inlet opening and outlet extending through the housing for the generator.
Claim 6
Dependent Claim
102 words
An enclosure for an engine and a generator, the enclosure adapted to be positioned in the front of a motor vehicle adjacent an inlet for the cooling air of the vehicle engine, the enclosure comprising: a housing enclosing both an engine and a generator; a first air inlet opening for the generator engine in a front of the housing; a first air outlet in a side of the housing; a second air inlet opening for a generator in a back portion of the housing; and a second air outlet for the generator, the second air outlet spaced from the second air inlet.
Claim 7
Dependent Claim
102 words
An enclosure for an engine and a generator, the enclosure adapted to be positioned in the front of a motor vehicle adjacent an inlet for the cooling air of the vehicle engine, the enclosure comprising: a housing enclosing both an engine and a generator; a first air inlet opening for the generator engine in a front of the housing; a first air outlet in a side of the housing; a second air inlet opening for a generator in a back portion of the housing; and a second air outlet for the generator, the second air outlet spaced from the second air inlet.
Claim 8
Dependent Claim
31 words
The enclosure as defined in claim 5 further including an air outlet duct in fluid communication with the air outlet and adapted to extend to the outside of a motor vehicle.
Claim 9
Dependent Claim
25 words
The enclosure as defined in claim 6 wherein the air outlet duct is constructed and arranged to accommodate an exhaust pipe for the generator engine.
Claim 10
Dependent Claim
21 words
The enclosure as defined in claim 5 wherein the first inlet opening is defined by a separate component from the housing.
Claim 11
Dependent Claim
26 words
The enclosure as defined in claim 8 wherein the housing for the engine and the generator is provided by a bottom portion and a removable top.
Claim 12
Dependent Claim
