The present invention provides system (100) for securing fuel of motor vehicles using IoT devices. The system comprises control device (101) mounted on lid of fuel tank to control the opening and closing of the lid of the fuel tank, from remote places. The control device (101) comprises plurality of IoT sensors connected to a microcontroller unit (205), a GSM module (202) to transfer the data between the authorized user and control device (101). The control device (101) also comprises microcontroller unit (205) to execute the plurality of operations and motor (207) integrated with microcontroller unit (205) to lock or unlock the lid of the fuel tank on receiving the signal from authorized user. An application is installed onto the user's mobile device (104) to monitor and track the activities in fuel tank. A cloud based database server (103) is used for storing and analyzing the measured fuel data.

A fuel pump system of a hybrid vehicle is provided. The fuel pump system prevents a fuel pump from continuing to operate when fuel is exhausted, whereby the fuel pump may be damaged. The pressure of fuel is measured in response to exhaustion of fuel, and when the pressure of fuel is low, fuel is circulated within the fuel pump instead of being supplied to the engine side, thereby preventing the fuel pump from being stuck due to frictional heat

A hydrogen generator for use with an inner combustion engine or other apparatus, even of a movable type, such as a home gas kitchen, said hydrogen generator comprises a system for separating hydrogen from ammonia, said system comprising a NH.sub.3 tank, an ammonia sucking pump, and a cracking oven containing a catalyst, an electric resistance and a H.sub.2/N.sub.2 separating centrifuge and including a suction device comprising a filter followed by a bottle for providing a feeding volume necessary for the produced hydrogen to compensate for user system requirement variations.

The present disclosure provides a male coupling member detachably couplable to a female coupling member that includes an outer coupling body having a first end inserted and fitted into the female coupling member, a second end opposite to the first end, and a passage extending from the first end to the second end. The male coupling member further includes an inner coupling body disposed coaxially with the outer coupling body at a position closer to the first end, and a filtration member detachably attached to the inner coupling body. The inner coupling body is attachable to and detachable from the outer coupling body from the first end. The filtration member is held in the passage when the inner coupling body is attached to the outer coupling body. The filtration member is detachable when the inner coupling body is detached from the outer coupling body.

A component for a plastic tank for a motor vehicle, said component being suitable for being inserted into a parison during a manufacture of the plastic tank for the motor vehicle. The component has at least one dimension, in at least one plane perpendicular to a direction of extrusion of the parison, which is substantially equal to or greater than a minimum distance between two opposing points located on a solid inner wall of the parison in said at least one perpendicular plane. The component includes a frame containing a first deflection means including at least one surface suitable for coming into contact with and guiding a travel of the parison when the component is inserted into the parison.

A fuel system for installation in a hydrogen-powered vehicle and for one or more hydrogen pressure tanks configured for a high pressure level of at least 200 bar, includes connections for input and output lines and at least the following internal components: a pressure reducer, a gas filter, a shut-off valve, a vent valve, an overpressure safety valve and a pressure sensor. The pressure reducer is a two-stage pressure reducer which reduces the pressure of the hydrogen from the high pressure level from the pressure tank to a medium pressure level between 3 bar and 30 bar. The first stage reduces the pressure from the pressure tank to an intermediate level between 40 and 80 bar and the second stage further reduces the pressure to the medium pressure level. The internal components and gas lines interconnecting these internal components are disposed in an integral and self-supporting modular unit.

A device is provided to prevent the accidental introduction of an incorrect liquid into a tank, such as the introduction of gasoline into the fuel system of a diesel fuel container. The device discriminates between nozzle diameters, allowing entrance of nozzle diameters at or greater than a predetermined minimum diameter while inhibiting entrance of nozzles having diameters less than the predetermined minimum diameter. A closure mechanism prevents access to a fuel container interior and a releasable locking mechanism responsive to nozzle diameters allows the closure mechanism to open and close to allow access to the fuel container interior.
