A engine starting method is carried out to start an engine of a vehicle. The vehicle includes a first hub, a second hub, and a damper. The damper connects the first hub and the second hub in a power transmission path between the engine and a generator capable of power generation and powered travel. The engine starting method determines whether or not the engine needs to be started, begins to crank the engine via the generator when the engine needs to be started, performs a first ignition when torque fluctuation caused by torsion in the first hub and the second hub is in a range of being absorbable by the damper during the cranking, and suppresses engine torque generated by the first ignition below engine torque generated by second and subsequent ignitions.

Disclosed is a control method for an internal combustion engine () including a power generation motor () driven by a power of the internal combustion engine () and a damper () provided between the internal combustion engine () and the power generation motor () in a power transmission path, wherein a maximum value of a torque fluctuation generated in an event of a misfire occurring in a cylinder of the internal combustion engine () is larger than a value at which a displacement of a main damper () of the damper () is allowed to be suppressed to be smaller than a displacement at which abutting occurs on a first stopper () by a counter torque of the power generation motor (), and the control method includes limiting a torque (Te) of the internal combustion engine () within a range in which a displacement of the main damper () is allowed to be controlled to be smaller than a displacement at which abutting occurs on the first stopper () by a counter torque of the power generation motor ().

Control method and control device for internal combustion engine

A method to modify the geometry of a connecting rod of an internal combustion engine includes providing a connecting rod having a crankshaft bore at a first end, wherein the first end has a bearing cap and a bottom end portion of the connecting rod, mating the bearing cap with the bottom end portion of the connecting rod to form the crankshaft bore of the connecting rod, machining a width upset portion of the bottom end portion to reduce a width of the bottom end portion of the connecting rod, machining a width upset portion of the bearing cap to reduce a portion of a width of the bearing cap, and reducing the width of the bottom end portion of the connecting rod and the portion of the width of the bearing cap to a width smaller than a cylinder bore of the internal combustion engine.
