Abstract: A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.

In a low-load operating range where it is not necessary for the dual-fuel injectors to inject fuel at the same time for ignition, fuel is injected alternately from the dual-fuel injectors and combusted in every single combustion cycle. As a result, it is possible to halve the amount of injection of oil fuel in the low-load operating range.
