A vehicle front end structure is provided with a vehicle body frame forming a frontward portion of a vehicle, a longitudinal acceleration sensor, a frontward vehicle component, a rearward extending part and a bracket. The frontward vehicle component is disposed to protrude farther forward than the vehicle body frame. The rearward extending part is connected to the frontward vehicle component and extends to a rearward position of the vehicle body frame. The bracket fixes the rearward extending part to the vehicle body frame at a connection area such that the rearward extending part is located farther rearward than the connection area of the vehicle body frame, with the bracket being constructed such that the rearward extending part releases from the vehicle body frame when a force acts to move the frontward vehicle component and the rearward extending part rearward.

A first compressor () which supercharges intake air is provided in the intake passage () of an internal combustion engine (). The first compressor () is driven by the exhaust gas energy of the engine (). A second compressor () driven by an electric motor (), and a bypass valve () which bypasses the second compressor (), are provided in the intake passage () between the first compressor () and the engine (). The bypass valve () shifts from the open state to the closed state according to the operation of the second compressor (). At this time, the bypass valve () starts closing at some time after startup of the second compressor () so that the intake air amount of the engine () is not deficient.

Supercharger for internal combustion engine

In an intake passage () of an internal combustion engine (), a compressor () combined with an electric motor/generator () is provided. A bypass valve () connecting upstream and downstream portions of the intake passage () to bypass the compressor () is further provided. When a required intake air flow rate of the engine () is smaller than a threshold value, the engine () operates by natural aspiration of intake air and the electric motor/generator () generate electric power by using rotational energy of the compressor () which rotates due to the flow of intake air. By increasing the opening of the bypass valve () as the required intake air flow rate diverges from the discharge flow rate of the compressor () the intake air flow rate is accurately controlled while satisfying the power generation requirement.
