Abstract

An internal combustion engine used for a vehicle comprises: a high-pressure fuel pump configured for pressurizing fuel supplied to an internal combustion engine; a pressurizer configured for pressurizing the air conveyed to the internal combustion engine; and an intercooler configured for cooling the pressurized air. The high-pressure fuel pump is arranged at an upper part of a cylinder cover of the internal combustion engine. The intercooler is arranged at a front side of the high-pressure fuel pump relative to the vehicle. An upper end of the intercooler is arranged to be higher than an upper end of the high-pressure fuel pump, so that the high-pressure fuel pump is covered by the intercooler within a surface of an internal combustion engine body when being observed from a front side of the vehicle.

Description

technical field [0001] The present invention relates to an internal combustion engine for a vehicle in which a fuel system can be accurately protected from damage by entry of a collision object. Background technique [0002] As an internal combustion engine for a vehicle, there is known an internal combustion engine provided with a cylinder injection valve for directly injecting fuel into a combustion chamber, and a valve injection valve for injecting fuel into an intake passage. Select switching between cylinder and port injection valves for purposes such as improved responsiveness, fuel efficiency or output to optimally control operating conditions. [0003] High-pressure fuel is supplied to a cylinder injection valve for directly injecting fuel into a combustion chamber through a high-pressure fuel pump driven by a camshaft. For this reason, the pump cam is provided in the camshaft, and the high-pressure fuel pump is provided in the cylinder head portion of the internal ...
