The present invention relates to a gas tank arrangement (100) for an internal combustion engine (102), said gas tank arrangement (100) comprising a gas tank (104) for containing a combustible gas, and an additional gas tank (106) arranged in upstream fluid communication with said internal combustion engine (102), wherein the gas tank arrangement (100) further comprises a valve arrangement (108) positioned in fluid communication with the internal combustion engine (102), wherein the valve arrangement (108) is further arranged in upstream fluid communication with the gas tank (104) and the additional gas tank (106) for controllably direct combustible gas from the internal combustion engine (102) to either the gas tank (104) or the additional gas tank (106).

A work vehicle including a drive device (10) having an internal combustion engine (12) for driving a vehicle body (1) has: a first tank (32) that is disposed in front of or behind the drive device, and stores fuel (9) to be supplied to the internal combustion engine; a second tank (34) that is disposed below the drive device so as to be separated from the first tank by a predetermined distance, and stores the fuel to be supplied to the internal combustion engine; a first storage amount detection part (70) that is disposed in the first tank, and detects an amount of the fuel stored in the first tank; and a second storage amount detection part (80) that is disposed in the second tank, and detects an amount of the fuel stored in the second tank.

A system, for use with a reservoir, for delivering an additive to a fuel tank is provided. The system comprises: a controller, the controller including a processor, a memory, the memory having housed therein instructions for controlling the processor, a display and a keypad; a temperature sensor, the temperature sensor in electronic communication with the controller; and a fluid delivery system, the fluid delivery system comprising: a pump, the pump for fluid communication with the reservoir and in electronic communication with the controller; a flow sensor, the flow sensor in fluid communication with the pump and in electronic communication with the controller; at least one valve, the valve in electronic communication with the controller and in fluid communication with the flow sensor; and at least one outlet, the outlet in fluid communication with the valve. A method of remotely adding an additive to a fuel tank is also provided.

A fuel tank device of a vehicle includes a fuel supply pipe, a first fuel tank, a second fuel tank, and a resistance portion. The fuel supply pipe includes a main pipe, and a first branch pipe and a second branch pipe that branch from the main pipe. The first fuel tank is connected to the first branch pipe, the second fuel tank is connected to the second branch pipe, and the resistance portion is provided in the main pipe and is configured to impart resistance to liquid fuel flowing in the main pipe.

Provided is a compressed natural gas (CNG) fuel system that can include a frame and at least one container. The frame can include a first side and a second side, with each side being configured to partly define a portion of an interior space. The at least one container can be configured to house or contain CNG and can be engaged to and partly encased by the frame. The at least one container can be partly located within the interior space of at least one of the first side or the second side. The frame assembly can be engaged to a chassis of a vehicle such that the at least one container is located either at least partially underneath a cab of the vehicle or at least partially behind a cab of the vehicle.

The technology disclosed by the invention relates to a pressure vessel system for a motor vehicle for storing fuel, comprising a plurality of pressure vessels (100) that are combined to a pressure vessel assembly (10), the pressure vessels (100), when mounted, being arranged substantially in parallel relative to each other, and the pressure vessels (100) being fluidically interconnected via a common fuel line (200).

A liquefied petroleum gas (LPG) filling system of a bi-fuel vehicle is provided. The LPG filling system may be configured for reducing the temperature and pressure in an LPG bombe for storing LPG in the case in which the external temperature is very high, e.g. in the hot season, whereby it is possible to easily refill the LPG bombe with LPG. The LPG filling system is configured to cool the inside of an LPG bombe and to reduce the vapor pressure of LPG by supplying some gasoline from a gasoline tank into the LPG bombe using the fact that the temperature of gasoline in the gasoline tank is lower than the temperature of LPG in the LPG bombe, whereby it is possible to easily refill the LPG bombe with LPG even in the case in which the external temperature is very high, e.g. in the hot season.

The at least one container can be configured to house or contain CNG and can be engaged to and partly encased by the frame. The at least one container can be partly located within the interior space of at least one of the first side or the second side. The frame assembly can be engaged to a chassis of a vehicle such that the at least one container is located either at least partially underneath a cab of the vehicle or at least partially behind a cab of the vehicle.

Provided is a saddle type fuel tank in which liquid fuel does not reach a canister through an exhaust passage immediately after full-tank refueling. The saddle type fuel tank includes a saddle type tank body and a full-tank regulating valve. The full-tank regulating valve includes a valve body, a float valve, a first hanging pipe communicatively connected to the valve body and having a first opening at a hanging end thereof, and a second hanging pipe communicatively connected to the valve body and having a second opening at a hanging end thereof. The first opening of the first hanging pipe is located at a height corresponding to a full-tank liquid level RA1_full in the first chamber. The second opening of the second hanging pipe is located at a height lower than that corresponding to a full-tank liquid level RA2_full in the second chamber.

A reserve fuel tank retention and control (RTRC) module and a method of operating a vehicle including an engine and a main fuel tank containing a fuel, the method including mounting the RTRC module onto the vehicle; fluidly connecting the RTRC module to the engine and to the main fuel tank; actuating a valve of the RTRC module for a predetermined time to purge moisture in a fuel supply hose into the engine; and upon the main fuel tank becoming empty, actuating the valve to allow fuel from the reserve fuel tank to supply the engine.
