Abstract
An embodiment hydrogen direct injection system for an internal combustion engine of a motor vehicle includes a fuel line and a fuel injector configured to inject hydrogen fuel into a combustion chamber of the internal combustion engine, wherein the fuel injector is configured to receive the hydrogen fuel via the fuel line and to receive water via the fuel line, and wherein the water is configured to lubricate the fuel injector.
Claims20
A hydrogen direct injection system for an internal combustion engine of a motor vehicle, the system comprising:
- a fuel line;
- a fuel injector configured to inject hydrogen fuel into a combustion chamber of the internal combustion engine, wherein the fuel injector is configured to receive the hydrogen fuel via the fuel line and to receive water via the fuel line, and wherein the water is configured to lubricate the fuel injector;
- and
- a water generator configured to generate the water by combining hydrogen with oxygen, wherein the water generator is fluidly connected to the fuel line of the fuel injector to deliver the generated water as a lubricant for the fuel injector and wherein the water generator comprises a fuel cell for combining the hydrogen with the oxygen.
A motor vehicle comprising:
- a vehicle body;
- an internal combustion engine mounted in the vehicle body;
- a fuel line;
- a fuel injector configured to inject hydrogen fuel into a combustion chamber of the internal combustion engine, wherein the fuel injector is configured to receive the hydrogen fuel via the fuel line and to receive water via the fuel line, and wherein the water is configured to lubricate the fuel injector;
- and
- a water generator configured to generate the water by combining hydrogen with oxygen, wherein the water generator is fluidly connected to the fuel line of the fuel injector to deliver the generated water as a lubricant for the fuel injector and wherein the water generator comprises a fuel cell for combining the hydrogen with the oxygen.
A method comprising:
- injecting hydrogen fuel with a fuel injector into a combustion chamber of an internal combustion engine of a motor vehicle, wherein the fuel injector receives the hydrogen fuel via a fuel line and wherein the fuel injector further receives water via the fuel line, the water being a lubricant for the fuel injector;
- and
- generating the water with a water generator by combining hydrogen with oxygen, wherein the generated water is delivered to the fuel line of the fuel injector as the lubricant for the fuel injector, wherein the water generator comprises a fuel cell that combines the hydrogen with the oxygen.
