Changing time integration in dieselEngineFoam

I'm a novice in the field of engine simulation and in the use of OpenFoam so be patient ...
My objective is to perform some simulations with dieselEngineFoam. I noticed that in fvSchemes file, the discretization in time is performed with a first order scheme by default. So I'm inquiring if this kind of accuracy should be improved by using a 2nd scheme in time at first glance such as the backward one, or the first order is enough for this kind of simulation.
However with the 2nd order schemes the constraint imposed by the Courant number should requires a small time step with expensive computational cost.
