    [0001] [0001] The present disclosure concerns an electronic engine control system that uses an exhaust emission sensor and adaptively maintains a given emission level. BACKGROUND OF THE INVENTION
    [0002] [0002] In a slow-moving vehicle, such as a farm tractor, the hot air coming out of the cooling system can be recirculated or dragged back to the intake of the cooling system. This reduces the potential for the airflow to perform useful cooling, thereby increasing the air mass required for cooling and, as a result, increasing the amount of fan power required. The fan power is parasitic in nature and, with the need for greater efficiency, keeping the fan power low is a high priority.
    [0003] [0003] Furthermore, Tier IV regulations require additional physical equipment that, if mounted on the engine housing, will require a thermal management strategy to prevent damage due to excessive temperatures under the hood.
    [0004] [0004] A known vehicle cooling system is described in U.S. Patent 7,051,786, issued May 30, 2006, and assigned to the applicant for this application. In this system, the hood has openings on its upper surface through which the air blown by the radiator fan unit and the charge air cooler fan unit passes. This cooling system blows heated cooling air vertically upwards, thereby preventing the heated cooling air from being drawn back into the cooling system inlets and preventing heated air from being blown out of the tractor cab. However, this system requires multiple cooling units and corresponding electric motor driven fans to blow air up.
    [0005] [0005] Another known vehicle cooling system is described in U.S. Patent 7,325,518, issued September 8, 2005, and assigned to the applicant for this application. This cooling system includes a pair of heat exchangers, such as an oil cooler and a cargo air cooler, laterally spaced from each other and located in front of a front end of the engine. A pair of blower units are in front of the coolers and blow cooling air back through it. A pair of duct units is located above the engine and at the rear of the coolers. Each duct unit includes an inlet leading to the front that receives hot air from the corresponding chiller, an outlet opening upward and a hollow housing extending from the inlet to the outlet. The exits are spaced laterally from each other. A radiator is positioned above the duct unit housings and to the front of the outlets. A set of radiator fans blows air up through the radiator and is positioned between the radiator and the duct housings. However, with this cooling system, the duct system needed to direct the used air flow to a useful space under the hood. Also, the amount of air movement under the hood was limited.
    [0006] [0006] Most previous and current production tractors do not have closed engine compartments. Some prior and current technology tractors, such as the John Deere 8030 tractor, have ducts that prevent air from ever reaching the engine compartment. Other well-known production tractors have a closed engine compartment, but have significant shutters to allow airflow to escape from the sides. SUMMARY OF THE INVENTION
    [0007] [0007] According to one aspect of the present disclosure, a vehicle engine box includes a tractor chassis that supports an engine. A cooling system is mounted on the chassis. The cooling system has a housing that surrounds the cooling components. A hood is mounted on the chassis and encloses the engine and the cooling system. The hood includes a top panel and side panels of the left and right hood. The top panel has exhaust fans formed on it. An upper seal seals the housing and the upper panel. A pair of left and right side plates is mounted on chassis 13. A pair of side seals is provided. Each side seal seals one of the hood's side panels and a corresponding plate from the side plates. A pair of lower seals are provided. Each bottom seal seals the chassis and a corresponding plate from the side plates. A rear end plate covers one rear end of the hood. A rear seal seals the rear end plate and the hood. The hood, side plates, chassis, engine and cooling system housing cooperate to form a duct that collects hot air and moves it vertically through exhaust fans to prevent the reentry of hot air.
    [0008] [0008] The engine housing also includes a front seal that has an upper strip and upper side strips that extend downwards from the upper strip. The upper strip forms a seal between the housing and the top panel of the hood. The upper side strips form a seal between the sides of the housing and the front side plates. The front seal also includes lower side strips that connect the upper side strips with a lower front seal strip. The lower side strips seal the hood and the front side plates.
    [0009] [0009] As a result, with this design, the engine compartment and the chassis are used to behave as a duct to minimize recirculation to the front grille. This improves the performance of the tractor and the cooling system, and allows thermal control of the components under the hood. BRIEF DESCRIPTION OF THE DRAWINGS

    [0017] [00017] Referring to figures 1-4, a tractor engine box 10 includes a hood 12 which is supported by the pivot close to its rear end in a conventional manner on a pivot chassis of the hood 11 which is supported on the chassis of the tractor 13. The hood 12 includes an upper panel 14 and a pair of side panels 16 and 18 that hang from the upper panel 14. A pair of side hoods 20, 22 is formed on each of the side panels 16, 18. The box also includes a pair of lower front side plates 24 and 26 and a pair of lower rear side plates 25 and 27, all of which are removable and which are supported on the chassis 13. The rear side plates 25 and 27 are preferably contoured to fit around the engine 30 and fit in the chassis 13. A plurality of upper openings or hoods 28 are formed in the upper panel 14. A pair of inlet openings 27 are formed at a front end of the upper panel of the hood 14. The hood 12 includes a the mesh grid 29 at its front end.
    [0018] [00018] Box 10 encloses a conventional internal combustion engine 30 that is mounted on chassis 13. Box 10 also contains a cooling system 32 that includes a rotating fan 34 with an external protection 36 connected to a housing 38 that involves components known cooling system, such as a radiator (not shown), a charge air cooler (not shown), a hydraulic oil cooler (not shown) and an AC condenser (not shown).
    [0019] [00019] As best shown in figures 2, 3 and 4, box 10 includes a front seal 40. The front seal 40 has an upper strip 42 and side strips 44 and 46 that extend downwardly from the upper strip 42. The upper strip 42 forms a seal between the housing 38 and the upper panel of the hood 14. The side strips 44 and 46 form a seal between the sides of the housing 38 and the front side plates 24 and 26, respectively. Curved side sealing strips 48 and 50 connect side strips 44 and 46, respectively, with a lower front sealing strip 52. Sealing strips 48 and 50 seal the hood 12 and the front side plates 24 and 26.
    [0020] [00020] As best seen in figures 3 and 4, box 10 also includes lower side seals 60 and 62. Seals 60 and 62 seal an upper surface of the chassis 13 and a lower edge of the front side plates 24 and 26, respectively .
    [0021] [00021] As best seen in figures 3, 5 and 6, box 10 also includes upper side seals 64 and 66. Seals 64 and 66 form seals between a lower edge of the side panels of the hood 16 and 18, and an edge rear side plates 25 and 27, respectively.
    [0022] [00022] As best seen in figures 2 and 8, box 10 also includes a rear end plate 70 that covers or fills the rear end of the hood 12 and which is attached by clamp 71 to the pivot frame 11. A seal 72 seals the rear end plate 70 and the top panel 14 and side panels 16 and 18.
    [0023] [00023] The result is an engine box that directs the hot air that leaves the cooling system 32 and that performs the function of a duct that collects the hot air and moves it vertically out of the tractor to prevent air readmission. Essentially, the kinetic energy in the air stream that leaves the cooling system 32 is transformed into potential energy in the form of pressure under the hood 12 and released as kinetic energy through the openings 28 in the top panel of the hood 14 in the form of an air jet. . The air that leaves the hood 28 openings is directed so that it is not readmitted or released against the cab glass (not shown) causing additional cabin heating.
    [0024] [00024] The advantage of this design is that the space, which would otherwise be needed to accommodate large ducts to direct the flow of hot air, becomes available for other purposes. In addition, a constant flow of air is provided to the engine compartment to prevent temperature-related damage from the increased thermal load associated with the mechanical equipment required by regulations.
    [0025] [00025] Although the disclosure has been illustrated and described in detail in the drawings and in the description presented, such illustration and description must be considered as exemplary, and not restrictive, and it should be understood that all changes and modifications that fit the spirit of the disclosure must be protected. It is noted that alternative modalities of the present disclosure may not include all of the features described, and also still benefit from at least some of the advantages of such features. Those skilled in the art can easily design their own implementations which incorporate one or more of the features of the present disclosure and which fall within the spirit and scope of the present invention, defined by the appended claims.
