Generation of intermediate code based on an abstract machine model is useful in compilers because

it makes implementation of lexical analysis and syntax analysis easier

syntax-directed translations can be written for intermediate code generation

it enhances the portability of the front end of the compiler

it is not possible to generate code for real machines directly from high level language programs
