DEP engineers develop a high efficiency GCI engine

INTRODUCTION

DEP does extensive research and development work for advanced powertrain development using the Model based system engineering approach. DEP provides CAE Solutions with high fidelity digital simulation model for Performance, Thermal Management, Fuel Economy, After-treatment System, Lubrication System and Competitor Benchmarking.

CHALLENGES

DEP was asked to develop a Gasoline compression ignition engine technology which is developed to improve Performance, Fuel Economy and Significant Emission reduction. The different optimizations are performance optimization, components optimization, mass efficiency strategy, engine testing, and general CAE functionalities like thermodynamics, systems modeling, combustion, heat/thermal management, induction/intake, block-head durability, crank-train dynamics, engine/powertrain NVH, ventilation, lubrication, etc.

SOLUTION

Based on the requirements brief, DEP’s product engineering team come up with Gasoline compression ignition engine technology which is developed to improve Performance, Fuel Economy and Significant Emission reduction.

DEP developed a detailed Lubrication model of crank train system for analysing & optimizing the performance of lubrication systems. Steady state model development with sub-assembly model integration (Crank train & valve train) was developed by DEP’s team to actually predict the bearing loads. DEP ensures broad application of 3D – 1D integrated modelling & simulation to analyse the crankcase pressure inside the engine & the blow by production as a function of speed & load via PCV valve.

RESULTS

Multiple iteration of simulations carried to calibrate the model with test data for performance, fuel economy and emission. The simulation focusses on performance optimization of PCV system by accurately matching the ventilation flow with blow by production characteristics while engine performance and drivability remains unaffected.
