Embodiment Construction
[0038] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0039] With reference to Figures 1 to 3, the profile of the flexible fuel injection cam of the present invention has a thrust section corresponding to the forward constant acceleration stage of the movement law of the plunger follower [0°, φ 1 ], working section [φ 1 , φ 3 ] and the forward and other deceleration stages [φ 3 , φ 4 ], the return section of the cam corresponds to the reverse constant acceleration stage of the plunger follower motion law [φ 4 , φ 5 ], reverse constant velocity stage [φ 5 , φ 6 ] (rate size is v 3 ) and deceleration stages such as reverse [φ 6 , φ 7 ]. The cam working section also includes the acceleration stage [φ 1 , φ 2 ] (initial rate is v 1 ) and forward constant velocity stage [φ 2 , φ 3 ] (rate size is v 2 ). The equations of motion for each segment of the plunger follower are:
[0040] 1. Forward constant acc...
