Abstract: A bi-fuel vehicle has an Internal Combustion Engine (ICE) to provide motive power to the vehicle by combustion of a liquid fuel and gas-phase fuel. The vehicle has a dual fuel tank including a liquid fuel tank to receive liquid fuel, contain the liquid fuel, and supply the liquid fuel for combustion in the ICE. The vehicle has a pressurizable gas-phase fuel tank defined by a wall. A gas-phase fuel is permeable through the wall. The pressurizable gas-phase fuel tank is to receive the gas-phase fuel, contain the gas-phase fuel, and supply the gas-phase fuel for combustion in the ICE. A shell envelops the pressurizable gas-phase fuel tank and defines an interior space of the liquid fuel tank. The wall is in fluid communication with the interior space. The interior space is to receive the permeated gas-phase fuel.

Abstract: A cooling system for a drivetrain of an electric vehicle includes a coolant circuit directing a flow of coolant through a first inverter and a second inverter of the drivetrain, and an adjustable flow valve positioned along the coolant circuit to selectably alter proportions of the flow of coolant directed through each of the first inverter and the second inverter. A method of operating a cooling system for a first inverter and a second inverter of a vehicle drivetrain includes commanding a speed and torque of each of the first and second inverter, and estimating losses and temperature of each of the first inverter and the second inverter as a result of the commanded speed and torque. A valve position of an adjustable flow valve operably connected to the first inverter and the second inverter is selected, and a change of the valve position is commanded.

Abstract: A method for early detection of a stochastic preignition (SPI) in an internal combustion engine includes monitoring sensor data from a sensor that is coupled to the internal combustion engine of a vehicle, determining whether a SPI event will occur using the sensor data and a Hankel Alternative View of Koopman (HAVOK) model, and commanding the vehicle to take a corrective action before the SPI event occurs to prevent the SPI event from happening in response to determining that the SPI event will occur.
