Abstract
A gaseous fuel supply system for a clean combustion engine of a vehicle having a vehicle cooling system. The supply system comprises: a gaseous fuel tank storing pressurized gaseous fuel; at least a first supply line arranged to supply pressurized gaseous fuel from the gaseous fuel tank to the clean combustion engine; at least a first heat exchanging component arranged in the first supply line. The first heat exchanging component is arranged to transfer heat between a cooling fluid of the vehicle cooling system and the pressurized gaseous fuel in the first supply line.

A gaseous fuel supply system for a clean combustion engine of a vehicle having a vehicle cooling system, the supply system comprising:
- a gaseous fuel tank storing pressurized gaseous fuel;
- at least a first supply line arranged to supply pressurized gaseous fuel from the gaseous fuel tank to the clean combustion engine;
- at least a first heat exchanging component arranged in the first supply line;
- wherein the first heat exchanging component is arranged to transfer heat between a cooling fluid of the vehicle cooling system and the pressurized gaseous fuel in the first supply line;
- a compressor arranged in the first supply line between the first heat exchanging component and the clean combustion engine;
- and
- a second heat exchanging component arranged between the compressor and the clean combustion engine, wherein the second heat exchanging component is arranged to transfer heat between the pressurized gaseous fuel in the first supply line and the cooling fluid of the vehicle cooling system;
- wherein the first and second heat exchanging components form part of a common heat exchanger.
A method for transferring heat between a gaseous fuel supply system for a clean combustion engine of a vehicle, and a vehicle cooling system, the method comprising:
- heating, by a first heat exchanging component, pressurized gaseous fuel in a first supply line transferring gaseous fuel from a gaseous fuel tank to the clean combustion engine, by the vehicle cooling system, the first supply line comprising a compressor arranged between the first heat exchanging component and the clean combustion engine;
- and
- heating or cooling, by a second exchanging component arranged between the compressor and the clean combustion engine, pressurized gaseous fuel in the first supply line, by the vehicle cooling system;
- wherein the first and second heat exchanging components form part of a common heat exchanger.
