Abstract
A novel in-cylinder fuel injector has been created for internal combustion engines using gaseous fuels such as hydrogen and low-carbon alternatives. This injector enhances the reliability and fuel efficiency of both spark-ignited and compression-ignition engines. The injector's innovative design encompasses a poppet-style valve for fuel injection and a fuel supply valve to govern fuel flow. Furthermore, it incorporates a distinct lubrication system that caters to the valve, seat, and sliding surface. Additionally, the injector includes valve actuators and a control system, effectively managing fuel injector actuation, injection timing, quantity, and valve actuation sequence. Notably, the design also integrates a lubrication system with a control valve.
Claims9
A compressed gas injector for mounting directly in a cylinder of an internal combustion engine, comprising:
- a poppet valve;
- an injector valve stem shoulder coupled to the poppet valve with drilled passages to supply or shut off compressed gas into the compressed gas injector in response to movement of the poppet valve;
- and
- a seat,
- wherein the poppet valve defines complementary seat angles between 25 degrees and 65 degrees.
