Oil splash simulation in final drive with Overset

The reduction of CO2 emissions is one of the biggest challenges to the automotive industry. An optimally designed driveline with effective cooling and lubrication provides substantial CO2 reduction. The cooling and lubrication performance is critical to the functionality and durability of vehicle drive units, such as transmissions and differentials. Final drive includes gears, bearings and shafts to transmit power from the engine to the wheels. Final Drives rely on splash lubrication where the oil flow is driven by the rotation of the gears and guided to important positions.

The cooling system has a key role in the design process of diesel engines: it allows the survival and the durability of the hottest components; also, performances and emissions are related to its efficiency.

Main aim of the system is to prevent cracks and thermal fatigue stress in base engine components: head and block first of all; for these components, a fluid core (cooling jacket) surrounds the hot surfaces related to the combustion and has to be designed as a main component of the system.

Thermal management has become a crucial issue in the design of modern vehicles. On one side, with high specific power outputs, the amount of excess heat to be disposed of is a serious challenge for vehicle reliability. On the other hand, at ordinary use, the excess heat available is limited and often insufficient to provide adequate heating to the cabin and to the catalytic converter controlling the vehicle harmful emissions. This is particularly true during the vehicle warm-up process in cold climates, significantly influencing real-world fuel consumption.
