ENGINE UNIT


  1. CONSTRUCTION


    1. A cam that drives the high-pressure fuel pump is positioned in both banks of the exhaust camshaft sub-assembly. Also, a pump cam with 3 peaks is used for the cam that drives the high-pressure fuel pump, and by synchronizing fuel pressure-feeding and fuel injection, the difference in fuel pressure between cylinders is reduced.

    2. The stem of the camshaft is made hollow, achieving weight reduction.

    3. The cam profile is shaped into a concave curve, increasing valve lift and improving output.

    4. A timing rotor, which is used for the camshaft position sensor and has a structure with 3 protrusions, is provided for the intake camshaft sub-assembly and exhaust camshaft sub-assembly.
