Vehicle simulation has become an essential tool for product design and emissions research in the automotive industry. In particular, simulation is used to help identify opportunities to reduce emissions from all stages of a vehicle’s life cycle, from manufacturing and driving to end-of-life disposal. Simulation may also be used to test new powertrain technologies and the environmental impact of proposed changes. Simulation helps automotive engineers quickly and efficiently design greener vehicles that meet or exceed performance targets thanks to its ability to accurately replicate complex systems and interactions.
What is a simulation, and how is it used in automotive engineering
Vehicle simulation involves the creation of virtual models that replicate the behaviour of actual vehicles. These models can study everything from aerodynamics and thermal management to acoustics and NVH (noise, vibration, and harshness). Automotive engineers use simulation to predict how a vehicle will perform in the real world before it is built or driven. It allows for more accurate testing and less expensive prototypes.
Simulation is also used extensively in emissions research. By understanding how pollutants are formed during different driving conditions, engineers can develop strategies to reduce them. For example, engineers can optimize fuel injection and air-fuel mixture by simulating different combustion cycles to minimize NOx emissions. In addition, by studying how pollutants disperse in the atmosphere, engineers can develop better after-treatment systems to remove them before they have a chance to impact air quality.
The benefits of simulation in vehicle design
Simulation provides many benefits to automotive engineers, including the ability to:
Save time and money: By identifying potential problems early in the design process, simulation can save automotive engineers time and money.
Evaluate multiple design options: Simulation allows automotive engineers to evaluate multiple design options quickly and easily. It is essential when exploring new powertrain technologies or making changes to an existing design.
Improve safety: By understanding how a vehicle will behave in different driving conditions, automotive engineers can ensure it is safe for drivers and passengers.
Protect the environment: Simulation can be used to study the environmental impact of proposed changes to a vehicle’s design. It helps automotive engineers make informed decisions about reducing a vehicle’s emissions throughout its life cycle.
Automotive simulation solutions are essential in helping automotive engineers design safer, more efficient vehicles. In addition, simulation can be used to study the environmental impact of proposed changes to a vehicle’s design.

Case studies of simulations that have helped reduce emissions and improve fuel economy
Advanced fuel injection modelling: By understanding how pollutants are formed during different combustion cycles, automotive engineers can develop strategies to reduce them. For example, by simulating different combustion cycles, engineers at Yamaha Motor Company could optimize fuel injection and air-fuel mixture to minimize NOx emissions. As a result of this work, Yamaha could reduce emissions from its vehicles by more than 80%.
Vehicle thermal management: Thermal management is a critical part of automotive engineering. To meet fuel economy and emissions targets, automotive engineers must design vehicles that dissipate heat quickly and efficiently. Simulation can be used to study how heat is transferred throughout a vehicle and identify potential areas of improvement. For example, engineers at Jaguar Land Rover used simulation to study the thermal management of an all-electric vehicle. By understanding how heat was generated and dissipated, they could make changes that improved the vehicle’s range by more than 20%.
Aerodynamic optimization: The aerodynamics of a vehicle have a significant impact on its fuel economy. Automotive engineers use simulation to study air flow around a vehicle and identify ways to improve its aerodynamic efficiency. For example, engineers at Volvo Cars used CFD (computational fluid dynamics) simulation to study the aerodynamics of a new SUV. Making changes to the SUV’s shape could reduce its drag coefficient by 8%. It helped improve the vehicle’s fuel economy by more than 5%.
A simulation is a powerful tool that automotive engineers can use to design safer, more efficient vehicles. In addition, simulation can be used to study the environmental impact of proposed changes to a vehicle’s design. It helps automotive engineers make informed decisions about reducing a vehicle’s emissions throughout its life cycle.
The future of simulation in vehicle design
As automotive engineering evolves, so too does the role of simulation. In the future, simulation will play an even more significant role in helping automotive engineers design safer, more efficient vehicles. In addition, the simulation will continue to study the environmental impact of proposed changes to a vehicle’s design. It will help automotive engineers make informed decisions about reducing a vehicle’s emissions throughout its life cycle.
