射式内燃機関。 The main intake valve includes at least two intake valves consisting of a main intake valve and a sub-intake valve, and at least two intake passages consisting of a main intake passage and a sub-intake passage, and has a main The intake passage is connected to the combustion chamber via the main intake valve, and the fuel injection valve is arranged in the auxiliary intake passage connected to the combustion chamber via the auxiliary intake valve, so that the main intake valve is near the top dead center of the intake stroke. In a fuel-injected internal combustion engine in which the sub-intake valve is open from the middle of the intake stroke to the beginning of the compression stroke, the fuel injection completion timing occurs when the engine temperature is lower than a predetermined temperature. A fuel-injected internal combustion engine with multiple intake valves designed to accelerate the
