We study the isochronicity of centers at O ∈ R 2 for systems αΊ‹ = -y + A(x, y), ẏ = x + B(x, y), where A, B ∈ R[x, y], which can be reduced to the LiΓ©nard type equation. When deg(A) 4 and deg(B) 4, using the so-called C-algorithm we found 36 new multiparameter families of isochronous centers. For a
