Abstract
An internal combustion engine includes an asynchronous injection valve configured to inject water into an intake port when one or more intake valves are closed and a synchronous injection valve configured to inject water into the intake port when the one or more intake valves are open. The asynchronous injection valve and the synchronous injection valve are configured to have injection characteristics that are different between the asynchronous injection valve and the synchronous injection valve.
Claims7
An internal combustion engine, comprising:
- a cylinder;
- an intake port coupled to the cylinder;
- one or more intake valves configured to selectively allow and block connection of the intake port to the cylinder;
- an asynchronous injection valve configured to inject water into the intake port when the one or more intake valves are closed;
- and
- a synchronous injection valve configured to inject water into the intake port when the one or more intake valves are open, wherein
- the asynchronous injection valve and the synchronous injection valve are configured to have injection characteristics that are different between the asynchronous injection valve and the synchronous injection valve,
- the one or more intake valves are two intake valves,
- the intake port is coupled to the cylinder by the two intake valves,
- the intake port has a width direction that extends in a direction in which the two intake valves are arranged, and
- the asynchronous injection valve is configured to inject water at a wider angle than the synchronous injection valve in the width direction of the intake port.
