  • Patent number: 11283333
    Abstract: In a coil forming device, an edge line in an escape region is formed so that a clearance between the edge line in the escape region and a recess portion in an axis direction is larger than a minimum clearance between the edge line in an inclined region and the recess portion in the axis direction.

  • Patent number: 10767577
    Abstract: A method of implementing control logic of a compression-ignition engine is provided. A controller outputs a signal to a injector and a variable valve operating mechanism so that a gas-fuel ratio (G/F) becomes leaner than a stoichiometric air fuel ratio, and an air-fuel ratio (A/F) becomes equal to or richer than the stoichiometric air fuel ratio, and to an ignition plug so that unburnt mixture gas combusts by self-ignition after the ignition plug ignites mixture gas inside a combustion chamber. The method includes steps of determining a geometric compression ratio and determining the control logic defining an intake valve close timing IVC. IVC (deg.aBDC) is determined so that the following expression is satisfied: if the geometric compression ratio ? is 10??<17, 0.4234?2?22.926?+207.84+C?IVC??0.4234?2+22.926??167.84+C where C is a correction term according to an engine speed NE (rpm), C=3.3×10?10NE3?1.0×10?6NE2+7.0×10?4NE.

  • Patent number: 10612474
    Abstract: Disclosed is a control device for a multi-cylinder engine having a combustion chamber (19) to which an intake port (16) and an exhaust port (17) are connected. The control device comprises: an intake-side variable valve operating mechanism (71) for controlling a lift timing of two intake valves (21a, 21b) of the intake port (16); an exhaust-side variable valve operating mechanism (72) for controlling a lift timing of an exhaust valve (22a); and an exhaust-side valve operating mechanism (73) for driving an exhaust valve (22b) at a fixed timing. The control device is operable, when executing cylinder deactivation in a low engine load and low engine speed operating range, to cause the exhaust-side variable valve operating mechanism (72) to open the exhaust valve (22a) during downward movement of a piston (14) in a cylinder (18) being subjected to the cylinder deactivation.
