The duct has an interior angle between 40 and 60 degrees. There are a plurality of flat (interior and exterior surface) sensor mounts disposed about and through the duct, including an octagonal ring of sensor mounts circumscribing the duct body. The cage has a flat front opposite the rear that has a larger diameter than a diameter of the rear. The duct has an aspect ratio of exterior angle length to diameter no greater than 3.5:1 and the duct and prefilter combined has an aspect ratio of exterior angle length to diameter no greater than 4.5:1.

A controller for a motor vehicle having an internal combustion engine, and a device for detecting a fire in a fluid conduit, the device having a fluid state sensor for detecting a state variable of a fluid that is conducted in the fluid conduit, are provided. The determination of a fire situation is performed in a manner dependent on a signal of the fluid state sensor.

Methods and systems are provided for accurately estimating intake aircharge based on the output of an intake oxygen sensor while flowing EGR, purge, or PCV hydrocarbons to the engine. The unadjusted aircharge estimate is used for engine fuel control while the hydrocarbon adjusted aircharge estimate is used for engine torque control. A controller is configured to sample the oxygen sensor at even increments in a time domain, stamp the sampled data in a crank angle domain, store the sampled data in a buffer, and then select one or more data samples corresponding to a last firing period from the buffer for estimating the intake aircharge.

The invention relates to a device for controlling the swirl of a fluid (2) flowing in a pipeline (1). The invention was based on the object of creating a device with which the adaptation of the swirl (2B) of a fluid (2) flowing in a pipeline (1), even in the case of constantly changing initial swirl (2B), to the desired flow conditions in the pipeline (1) is possible. Said object is achieved in that a swirl measuring device (4) and a swirl control device (6) are provided at predetermined positions of the pipeline (1), and the device has an evaluation and encoder unit (5), wherein, in the presence of differences between the measured actual swirl (2B) and the desired swirl, a corrective value can be determined by means of the evaluation and encoder unit (5), and the swirl control device (6) corresponds with the evaluation and encoder unit (5) and, by means of the swirl control device (6), the present swirl (2B) can be adapted to the predetermined desired swirl in accordance with the determined corrective value.

An intake adaption system for internal combustion engines of vehicles employing an aftermarket intake air assembly including high capacity intake ducting and a low resistance air filter. Intake air sensors provide intake air condition signals of filtered intake air to the engine. A CPU includes a routine for modifying the intake air condition signals of the filtered intake air to the ECM. Tables alter the appropriate sensor signal or signals to correct for the calibration and predictions made by the ECM based on the original equipment. A first table translates the intake air condition signals from the intake air sensors indicative of MAF into the engine to provide actual MAF into the engine. A second table generates a pressure offset responsive to MAF into the engine to provide the ECM with a lower pressure value than actual, avoiding a diagnostic trouble code.

The hydrogen production system for internal combustion engines includes an intake air scoop, a vacuum block having an air input port system for receiving air from the intake air scoop, a water reservoir connected to the vacuum block for providing water to be mixed with the air in the vacuum block, at least one primary generator assembly with an inlet port for receiving the air/water vapor mixture from the vacuum block and producing a mixture of hydrogen, produced oxygen, and fine hydrogen production vapor from a partially oxidized water fog, and a plurality of secondary hydrogen generator assemblies connected to the primary generator assembly for receiving this mixture. The engine vacuum draws this mixture into the intake manifold to provide an ideal fuel mixture for the engine.

A snow bike intake, snow bike conversion kit, and/or air intake pod snow bike conversion kit, having; a throttle body coupling; an elbow-shaped intake duct coupled to the throttle body, a pre-filter body cage coupled at a rear thereof to the duct and a textile cover fitting about the cage. The duct has an interior angle between 40 and 60 degrees. There are a plurality of flat (interior and exterior surface) sensor mounts disposed about and through the duct, including an octagonal ring of sensor mounts circumscribing the duct body. The cage has a flat front opposite the rear that has a larger diameter than a diameter of the rear. The duct has an aspect ratio of exterior angle length to diameter no greater than 3.5:1 and the duct and prefilter combined has an aspect ratio of exterior angle length to diameter no greater than 4.5:1.

An attachment mechanism for electronic equipment for an engine includes a bracket configured to hold the electronic equipment and a plurality of support portions configured to elastically support the bracket with respect to a head cover of the engine. The support portions are disposed such that a maximum distance between two support portions of the support portions in a direction parallel to a shaft center of a crankshaft of the engine is longer than a maximum distance between the two support portions of the support portions in a direction perpendicular to the shaft center of the crankshaft of the engine.
