A tank system for a construction machine includes a fuel tank having an outer tank wall that closes off a tank volume to the outside, a withdrawal tank volume, which is separated by a partition wall from a main tank volume of the tank volume and has a fuel-exchanging connection to the main tank volume, and a fuel withdrawal arrangement having a main fuel pump and a withdrawal line opening into the withdrawal tank volume for conveying fuel by the main fuel pump via the withdrawal line from the withdrawal tank volume to a fuel-consuming system region. The tank system also includes a fuel feed arrangement having an auxiliary fuel pump for conveying fuel from the main tank volume into the withdrawal tank volume.

An electrically-operated ON/OFF valve for a high pressure hydrogen tank for an automotive fuel cell system has a valve body, a solenoid group, a first gate that achieves a first-stage seal, and a sealing element provided with a main sealing surface to achieve a second-stage seal. The first-stage seal and the second-stage seal are both achieved by the sealing element.

Estimating a fuel consumption includes receiving a request for estimating the fuel consumption between a first time and a second time; estimating a first fuel consumption value in a first time interval using fuel-sender resistance data; estimating a second fuel consumption value in a second time interval using fuel-injected mass data, where the first time interval and the second time interval are consecutive, non-overlapping intervals; and combining at least the first fuel consumption value and the second fuel consumption value to obtain a fuel consumption value.

A tank includes a tank body made of a thermoplastic resin, a female screw member and a joint that are made of metal, and a seal member. The tank body has a tubular connection port with a through hole, and an inner space communicating with the connection port. The joint has a male screw portion to be screwed into a female screw hole of the female screw member, a boss portion connected to the male screw portion, and a joint through hole passing through the male screw portion and the boss portion. The seal member is provided so as to contact the boss portion and the hole side surface when the male screw portion is screwed into the female screw hole. The boss portion is contactable with a first bearing surface of the female screw member.

A refuse vehicle includes a vehicle chassis and an all-electric vehicle body on the chassis. The body includes a hopper, a refuse storage container, and a plurality of electrically powered body systems. The body systems include an electrically actuated tailgate, an electrically actuated refuse loading assembly, and an electrically actuated refuse packing assembly configured to remove refuse from the hopper and to pack said refuse in the storage container. The vehicle (e.g., vehicle body) further includes a power management module configured to regulate energy usage of the body systems and/or to record and track electrical energy usage in the body systems.

A gas detection device includes a gas sensor and a drive circuit. The drive circuit includes a measurement circuit, a power supply circuit, and a control circuit. The gas sensor includes a first electrode, a second electrode, a metal-oxide layer disposed between the first electrode and the second electrode, and an insulating film that covers the first electrode, the second electrode, and the metal-oxide layer, and has an opening that exposes part of a main surface of the second electrode. A resistance value of the metal-oxide layer decreases when gas containing hydrogen atoms contact the second electrode. When the resistance value of the metal-oxide layer falls outside a predetermined range, the drive circuit applies a predetermined voltage between the first electrode and the second electrode to restore the resistance value of the metal-oxide layer back into the predetermined range.

A throttle valve for adjusting the feeding of a gas to a fuel cell, which includes: a valve body, divided into a first and a second portion; a gas feeding duct obtained in the first portion; a throttle plate arranged in the feeding duct; a shaft which is rotatably mounted in the first portion and supports the throttle plate; and an actuator which is mounted in the second portion and is configured to rotate the shaft. The throttle valve further comprises a magnetic joint, which transmits the motion from the actuator to the shaft and is divided into a first half coupled to the shaft, and a second half facing the first half and coupled to the actuator. The throttle valve also includes an insulating wall which insulates the first partition, in a pneumatically sealed manner, from the second portion of the valve body and is arranged between the two halves of the magnetic joint.

An embodiment mounting structure includes a rear side member having a rear end portion configured as a deformation-inducing portion, and a mounting portion configured to fix a fuel storage device to a portion in front of the deformation-inducing portion in the rear side member. An embodiment vehicle includes a vehicle body including rear side members on opposite sides of the vehicle body, each of the rear side members having a rear end portion configured as a deformation-inducing portion, a fuel storage device, and mounting brackets each coupled to a respective one of the rear side members and configured to fix the fuel storage device to a portion of the rear side members in front of the deformation-inducing portion.
