AS REPORTEDno primary record reached; this is what the reporting says

Is it true that the Otto cycle is a thermodynamic cycle that consists of a pair of adiabatic processes and a pair of isochoric processes?

Yes. The Otto cycle consists of a pair of adiabatic (isentropic) processes and a pair of isochoric (constant volume) processes, as confirmed by standard physics references.
