Abstract (en)

[origin: US5586527A] PCT No. PCT/DE93/01248 Sec. 371 Date Jun. 9, 1995 Sec. 102(e) Date Jun. 9, 1995 PCT Filed Dec. 22, 1993 PCT Pub. No. WO94/16203 PCT Pub. Date Jul. 21, 1994The invention relates to a possibility for the relative rotation of two camshafts for the control of internal combustion engines, more particularly to reduce the gas exchange losses of reciprocating 4-stroke engines. The invention more particularly enables very large adjustment angles of up to 220 DEG crank angle to be obtained.
