Internal combustion engine with thermochemical recuperation of waste heat and a method for thermochemical recuperation

A thermochemical recuperation (TCR) system, comprising:

• a TCR reformer configured to output a TCR product;
• a pressure regulator;
• a TCR product accumulator configured to separate an outputting of the TCR product by the TCR reformer from a provision of the TCR product to the pressure regulator;
• and
• a circulation pump that is configured to receive a water-alcohol mixture from a cooling jacket of the engine, and to circulate the water-alcohol mixture at a pressure value higher than a boiling point under a water-alcohol mixture working temperature;
• wherein the pressure regulator is configured to provide the TCR product to a direct injector of an engine, thereby enabling the direct injector to inject the TCR product at a high pressure level.

• a TCR product accumulator configured to separate an outputting of the TCR product by the TCR reformer from a provision of the TCR product to the pressure regulator;
• a coolant circulation pump;
• a coolant radiator having an output that is fluidly coupled to an input of a cooling jacket of the engine;
• a coolant thermostat that is fluidly coupled between the coolant circulation pump and the coolant radiator;
• an evaporator;
• a pump having an input that is fluidly coupled to an output of the coolant circulation pump and an output that is fluidly coupled to an input of the evaporator, the TCR reformer;
• and
• a liquid phase drainage having an input that is fluidly coupled to an output of the TCR reformer and an output that is fluidly coupled to an input of the pump;
• wherein the pressure regulator is configured to provide the TCR product to a direct injector of an engine, thereby enabling the direct injector to inject the TCR product at a high pressure level.
