Summary:

This study employs TRIZ, the Theory of Inventive Problem Solving, to optimize a 2.2-liter automotive diesel engine facing challenges from system technology upgrades in the fuel injection system. This system requires the common rail pump. Two pumps were chosen and based on fuel quantity balance (QB) and drive ratio, one pump was finalized as the technical option, and it was studied in a detailed manner to identify the improving and worsening parameters with the help of a contradiction matrix and the 40 TRIZ principle, which are the main core ideas of TRIZ. The worsening parameters (drive torque) are reduced by 21.36%, and the chain load in the 0.5% worn chain condition also fulfills the system requirement.The chosen pump is further studied. This also helped to identify and categorize the system components of the main engineering system into subsystems and supersystems. Through functional analysis and cause-and-effect chain analysis, the timing issue is identified. and in the trimming stage, using Rule 3, this timing of the pump is resolved. Supporting results and TRIZ findings have been discussed in detail
