Abstract
A vehicle provided with a power plant having at least one heat engine, the vehicle having an air-conditioning system comprising a fluid circulating in a fluid circulation system, the fluid circulation system comprising at least one pump configured to cause the fluid to circulate in a fluid circuit. The vehicle comprises one injection member per heat engine configured to inject the fluid into the associated heat engine, the vehicle comprising a back-up circuit fluidly connecting the fluid circulation system to each injection member, the back-up circuit comprising a distribution device controlled by a controller to authorize, on command, circulation of the fluid towards an injection member.
Claims18
A vehicle provided with a power plant, the power plant having at least one heat engine, the vehicle having an air-conditioning system for controlling the air temperature in a section of the vehicle, the air-conditioning system comprising a fluid circulating in a fluid circulation system, the fluid circulation system comprising a fluid circuit running through the vehicle, the fluid circulation system comprising at least one pump configured to cause the fluid to circulate in the fluid circuit,
- wherein the vehicle comprises an injection member per heat engine of the at least one heat engine, the injection member being configured to inject the fluid into the associated heat engine, the vehicle comprising a back-up circuit fluidly connecting the fluid circulation system to the injection member, the back-up circuit comprising a distribution device controlled by a controller to authorize, on command, circulation of the fluid towards the injection member.
A method for assisting a power plant of a vehicle, the power plant having at least one heat engine, the vehicle having an air-conditioning system for controlling the air temperature in a section of the vehicle, the air-conditioning system comprising a fluid circulating in a fluid circulation system, the fluid circulation system comprising a fluid circuit running through the vehicle, the fluid circulation system comprising at least one pump configured to cause the fluid to circulate in the fluid circuit,
- wherein the method comprises an assistance phase of assisting a heat engine to be assisted from the at least one heat engine, the assistance phase comprising the following step:
- activation, on command from a controller, of a distribution device present in a back-up circuit fluidly connecting the fluid circulation system and an injection member, in order to convey the fluid to the injection member supplying fluid to the heat engine to be assisted.
