SYSTEM ENGINEERING
The basis for efficiency and sustainability
Design Idea
Automotive engine development is a continuous pursuit of enhancing performance, efficiency, and reducing environmental impact. It all begins with a well-conceived design idea. Engineers brainstorm and strategize to develop innovative concepts that optimize power output, minimize fuel consumption, and reduce harmful emissions. They consider various factors such as combustion chamber design, valve configuration, and piston shape to achieve the desired objectives.
FEM Calculation
Finite Element Method (FEM) plays a crucial role in the engine development process. By subjecting the engine components to virtual simulations, engineers can analyze stress distribution, deformation, and structural integrity. FEM calculations help optimize the engine’s design by ensuring it can withstand the demanding conditions of everyday usage and deliver exceptional performance over its lifespan.
Emission Calculation
In the era of stringent emission regulations, automotive engines must comply with increasingly strict standards. Engineers employ advanced emission calculation techniques to estimate and minimize the release of harmful pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM). These calculations guide the development of emission control systems, including catalytic converters and exhaust gas recirculation (EGR) systems, to ensure the engine meets regulatory requirements without compromising performance.
Mass Transfer Analysis
Mass transfer analysis is essential for optimizing fuel injection systems and combustion processes. Engineers utilize this analysis to determine how efficiently fuel is mixed with air, ensuring complete combustion and reducing fuel wastage. Improving mass transfer efficiency results in better fuel economy and reduced greenhouse gas emissions.
CFD / Flow Measurement
Computational Fluid Dynamics (CFD) simulations and flow measurements are indispensable tools in engine development. CFD helps analyze air intake, exhaust gas flow, and combustion characteristics within the engine. By fine-tuning intake and exhaust port shapes, engineers can enhance airflow, reduce turbulence, and improve overall engine efficiency.
Material Development
Engine components undergo extreme conditions, necessitating the use of advanced materials. Engineers work closely with material scientists to develop high-strength alloys, heat-resistant ceramics, and lightweight composites. These materials enhance engine durability, reduce weight, and improve thermal efficiency.
Vibration Analysis
Vibration analysis aids in identifying potential issues and improving engine reliability. Unwanted vibrations can lead to component fatigue and failure. By conducting vibration analysis, engineers can optimize the engine’s design, implement effective damping systems, and ensure smooth and stable operation.
Shape Analysis
Shape analysis focuses on optimizing the overall engine configuration to reduce drag and improve aerodynamics. A streamlined engine design minimizes air resistance, contributing to improved fuel efficiency and reduced CO2 emissions.
KLT Test / Thermal Shock / Hot Vibration
KLT (Key Lifetime Test), thermal shock tests, and hot vibration tests are performed to evaluate the engine’s robustness under extreme conditions. This is an extended testing process conducted on vehicles or their components to simulate the wear and tear they might experience over the course of their expected lifespan and subject the engine to harsh temperature variations, mechanical stresses, and vibrations, replicating real-world driving scenarios. By passing these tests, the engine proves its reliability and durability.
Engine Test Bench
Engine test benches are used to evaluate the engine’s performance, emissions, and efficiency in controlled laboratory settings. Engineers conduct a series of tests, including full-load tests, part-load tests, and transient response tests to validate the engine’s performance against design objectives.
Vehicle Dynamometer
Once the engine proves its worth on the test bench, it undergoes vehicle dynamometer testing. This involves installing the engine in a vehicle chassis mounted on rollers. The dynamometer measures the engine’s power output, fuel efficiency, and emissions under realistic driving conditions. This step ensures that the engine functions optimally within the context of the entire vehicle system.
