Abstract: The present disclosure relates to systems and methods for managing vehicle operations utilized for autonomous driving. An example method includes obtaining a set of inputs corresponding to a set of operational information associated with a vehicle; responsive to determined trigger, processing the set of inputs to determine whether the vehicle is available for travel; processing the set of inputs to determine whether at least one occupant has indicated an intent for the vehicle to initiate travel; responsive to determined vehicle availability for travel and determined intent for the vehicle to initiate travel, identifying a set of vehicle operational parameters corresponding to a determined path of travel; and causing the initiation of the identified set of vehicle operational parameters.

Abstract: A fuel lock/converter having an integrated housing with a liquid fuel inlet port and a gaseous fuel outlet port. The outlet port discharges to an air/fuel mixer which acts as a carburetor and its demand controls this fuel lock/converter. Between the inlet port and the outlet port there is a fuel lock which closes in the absence of demand, and opens at any demand. A primary regulator valve regulates liquid flow to a converter, and gaseous fuel from the converter is regulated by a secondary regulator valve. The secondary regulator valve also acts as a fuel lock in the absence of demand.

Abstract: The invention provides a mixture control system for controlling the flow of vaporized hydrocarbons drawn into an engine for combustion and combining a supplemental fuel with the vaporized hydrocarbons as required to maintain a near stoichiometric mixture.

Abstract: An economizer valve for use with an induction and fuel supply system for an internal combustion engine operated on gaseous fuels, for example, LPG or natural gas. The system is used with a conventional mixing valve which supplies air according to engine demand, together with fuel appropriate to the desired charge, and includes a regulator for providing gas to the mixing valve, and an economizer valve responsive to pressure regions upstream from and at and downstream from a throttle valve, effective on the regulator to cause it to lean out the charge under certain conditions and to permit the charge to be enriched at other conditions.
