Abstract
A vehicle system, comprising an internal combustion engine, a transmission enclosed within a transmission case coupled to a gaseous fuel source, the transmission case having an amount of gaseous fuel located therein. Housing the transmission in a case containing low density gaseous fuel reduces the power losses from air resistance and increases fuel efficiency.
Claims17
A vehicle system, comprising:
- an internal combustion engine;
- a transmission enclosed within a transmission case that is fluidically coupled to a gaseous fuel source, the transmission case having an amount of gaseous fuel located therein;
- and
- a purge canister fluidically coupled to the transmission case via a line, wherein the transmission case is further fluidically coupled to a motor case, a generator case, or a combination thereof.

A method for a vehicle, comprising:
- delivering a gaseous fuel into a transmission case of the vehicle;
- delivering the gaseous fuel into an electric motor case;
- and
- determining an amount of gaseous fuel delivered into the electric motor case in response to an amount of air resistance desired within the electric motor case.
1 more element
A method for a vehicle, comprising:
- delivering a gaseous fuel into a transmission case of the vehicle;
- delivering the gaseous fuel into an electric generator case;
- and
- adjusting an amount of the gaseous fuel within the transmission case in response to an air to fuel ratio (AFR) within the transmission case being above a threshold.
