1. A method (100) for increasing power output of an internal combustion engine while retaining an existing engine architecture, the method (100) comprising steps of: increasing peak firing pressure of a multi-cylinder engine from approximately 160 bar to approximately 210 bar; and achieving torsional system compliance exclusively through crankshaft design optimization, without modification to crankshaft material specification, front-end accessory drive layout, or rear-end layout; evaluating torsional behavior of an existing crank-train system under baseline and increased peak firing pressure conditions using a one-dimensional multi-body simulation model derived from a three-dimensional crankshaft geometry;

2. The method (100) as claimed in claim 1, wherein the engine is a six-cylinder in-line, overhead-valve engine operating at a fixed speed, such that torsional response is governed primarily by peak firing pressure rather than speed variation.
