Abstract:
In at least some embodiments, the present invention relates to an air cleaner having a housing portion, and a low profile rain cover having an opening on an underside of the cover to allow unfiltered air to enter into the air cleaner. Also, in at least some embodiments, the present invention relates to an air cleaner including a housing and an additional component by which the air cleaner is capable of being directly coupled to a carburetor inlet. In some such embodiments, one or more protrusions can be provided within a channel formed by the housing/additional component to influence air flow. Further, in at least some embodiments, the present invention relates to an air cleaner having a shaped wall formed on a housing portion, where the shaped wall includes both an interior surface and an exterior surface by which air flowing within the air cleaner is imparted with helical motion.
Abstract:
An air cleaner is provided in an all terrain vehicle in order to improve the control performance for effecting optimal combustion in an engine by accurately measuring the temperature of air introduced into the engine. The air cleaner includes an air cleaner case disposed behind an engine, a throttle valve disposed between the engine and the air cleaner case, and connecting tube for connecting the air cleaner case and the throttle valve with each other. A temperature sensor is disposed in either a front or rear face of the air cleaner case. Optionally, the temperature sensor is disposed in the connecting tube.
Abstract:
Efficiency leading to saving in transportation is a must at this competitive era. The choice of an automotive vehicle as a transportation means in mining, plantation, and forestry entails a special tactics in order to minimize the operational, maintenance and replacement cost of the air filter used in its internal combustion engines, especially the air filter whose entire parts should be replaced when its clogged filtering medium (7) is replaced. The air filter presently invented is a knocked-down air filter, i.e., an air filter whose part that should be replaced is its filtering medium (7) and inner mesh (6) only which are bound together by lower rubber (5) and upper rubber (8). Its other parts such as lower housing (1), upper housing (9), perforated plate (3) and reinforcing pile (4) are not necessarily replaced. A manually opened and closed locker (11) unite this knocked-down air filter as a single unit.
Abstract:
An intake system for an internal combustion engine includes an intake manifold adapted to be attached to a side wall of the engine, and an air cleaner for supplying intake air to the intake manifold. The air cleaner is disposed opposite to the side wall of the engine while interposing therebetween the intake manifold. The air cleaner has an air cleaner main body joined with the intake manifold to constitute a single unit. The air cleaner main body is made of a material lower in the strength than a material which the intake manifold is made of.
Abstract:
An air induction system comprises flow body (32) and a filter housing (20). The filter housing (20) has a first housing portion (36) and a second housing portion (40) in communication with the air flow body (32). A filter (44) is disposed in the filter housing (20). A connector comprises a wing (54) mounted to a post (70) extending from the first housing portion (36) and a slot (56) on the second housing portion (40). (FIG. 4). The first housing portion (36) has at least one cutout (60) adjacent post (72). (FIG. 4).
Abstract:
A structure for cooling one or more units built in a hybrid vehicle, where the structure is simple and can be inexpensively realized, and has a high cooling efficiency. The hybrid vehicle has an internal combustion engine and high-voltage units which include a motor which assists driving power of the engine and also functions as a power generator, a high-voltage storage battery for storing generated power, and a high-voltage controller provided between the motor and the storage battery. At least one of the high-voltage units is provided in an air intake passage for the engine, through which an air passes while cooling said at least one of the high-voltage units.
Abstract:
An improved air box lid and an improved air conveyance tube may be used alone and/or in combination to improve engine performance. For example, the improved air box lid and the improved air conveyance tube may be used together in an air induction system to increase the flow of ambient air from an air intake box to the motor throttle body. The improved air box lid and the improved air conveyance tube are preferably provided with interior walls that are smooth and continuous and define only obtuse interior angles.
Abstract:
The present invention concerns an air filter unit for a vehicle with an internal-combustion engine. Air filter unit for a vehicle with an internal-combustion engine, comprising an air filter and a hollow case containing and holding the air filter in position, characterised in that said case is composed, on the one hand, of a lower part forming an open receptacle for said filter and made up of at least two elementary parts assembled at complementary formations of their edges placed in contact and, on the other hand, of an upper part forming a cover and closing the upper part of the lower part, said upper and lower parts being assembled, with insertion of a seal or a packing, at the lower peripheral edge of said upper part and at the peripheral edge of the opening of the lower part.
Abstract:
An air cleaner includes a slide retention structure which engages a sliding resonator volume. The volume slides along the slide retention structure into an assembled position. Once assembled, a tuning tube engages an aperture in the volume, the volume and the resonator assembly reducing noise produced by the engine. A flexible seal is positioned around the aperture to acoustically seal the resonator volume to the tuning tube. An air cleaner cover is secured to the box by a lock plate. To lock the cover to the box, the lock plate is slid so that a plurality of wedges on the plate are forced under hooks on the box, securing the cover to the box. A side opening located proximate to the wedges allow the lock plate to slide so that the hooks do not hinder the movement of the lock plate.
Abstract:
To enlarge an opening area in an element retainer supporting a clean side of an element, to reduce resistance to air passage and thereby to enlarge intake air quantity. The interior of an air cleaner is surrounded by a case and a lid is partitioned by an element into a dirty side and a clean side. An opening portion on the side of the clean side of an element holder supporting the element is covered by an element retainer, and the element retainer is formed in the shape of a louver.
