Abstract: A vehicle speed limiting device is designed for use with diesel engines, particularly those in over-the-road trucks. A D.C. pulse generator is attached at the wheel or transmission speedometer pickup and provides a signal to a speed switch which includes a frequency-to-voltage converter which processes the pulse signal. The converter output is then compared to a reference voltage corresponding to a predetermined speed limit, generally 55 miles an hour. When the vehicle speed and corresponding voltage exceeds the reference voltage and speed, the comparator operates a relay which opens or closes a solenoid valve in the fuel supply line of the truck. In most applications, the solenoid valve is placed between the fuel pump and the injector and fuel flow is diverted from the injectors to the upstream side of the pump. A small amount of fuel is allowed to continue to the injectors to provide for proper lubrication thereof.

Abstract: A fuel tank is provided for the automotive transport of a cryogenic liquid fuel which in the course of transport is being consumed by an engine or the like. The fuel tank consists essentially of two containers, one for the cryogenic fuel and the other for a secondary cryogenic liquid which is used to cool the fuel during storage when no fuel is being consumed. By the method of the invention the build up of fuel vapor pressure during storage is avoided and the vapor pressure maintained at a predetermined level. The fuel tank described herein was two distinct modes of operation, namely, the fuel storage mode and the fuel supply mode. In the fuel storage mode the cryogenic fuel is being stored for later use while the secondary fluid is being used as a heat sink for the heat absorbed by the tank from the environment.
