Abstract
A system may include a first methanol tank and a second methanol tank connected to the first tank. The system may include a first valve fluidly connected to the first methanol tank and the second methanol tank. The system may include a heat exchanger connected to the second methanol tank and a turbine of a turbocharger. The system may include a second valve fluidly connected to an intake system of an engine.
Claims20
A system, comprising:
- a first tank containing methanol;
- a second tank configured to receive a portion of the methanol from the first tank;
- a heat exchanger configured to provide heat, from an exhaust gas to the second tank to increase a temperature of the portion of the methanol, in the second tank, to generate vaporized methanol,
- wherein the heat exchanger is external with respect to the second tank, and
- wherein a pressure of the vaporized methanol causes the vaporized methanol to be provided to an intake system associated with an engine;
- and
- a valve configured to cause a portion of the vaporized methanol, in the second tank, to be provided to the first tank to reduce at least one of a temperature of the vaporized methanol or the pressure of the vaporized methanol.
