The core competence of the ITB GmbH in the automotive sector is the engine with all its fluidic components.
We calculate all occurring fluid circuits in a combustion engine, these are:
- Air intake &rarr exhaust tract
- Coolant circuit
- Oil circuit
- Fuel supply
Without air the engine doesn't work, our tasks are here:
- Untreated air route and clean air route (intake path)
- Intercooled track / intake system
- AGR mixing low pressure range
- Gas exchange to determine the volumetric efficiency
- Digital blowing laboratory to evaluate the intake and exhaust ports
The exhaust section is full of challenges for the CFD and FEM calculations, the high component temperatures make a thermal protection necessary.
ITB has expertise in these areas:
- Exhaust manifold
- Exhaust system with DOC, DPF, SCR + Exhaust aftertreatment
- High-pressure-AGR-route- with AGR cooler
The high power densities of engines cause that many components are supplied with a coolant. Please read our expertise engine cooling.
The lubrication of the moving components undertakes the third fluid circuit, the oil. Our calculation methods show whether oil goes everywhere, where lubrication is necessary or whether the contamination of the air path can be excluded with oil through the oil separator. Besides the evaluation of the pressure drop for the design of the pump, in the oil circuit, the functionality of the oil filtering is also interesting.
Fuels are used in combustion engines as an energy carrier. In addition to classic fuels, diesel and gasoline, which are supplied in liquid form, is being used as alternative fuels for some time. The most widespread is in this case the natural gas, which is fed in gaseous form the combustion chamber or inlet port.
As a method we use both the 1D system simulation and 3D flow simulation. In some processes, additional physical models such as the cavitation are needed to map the flow processes realistically.
