What is the difference between multi port fuel injection and direct injection?
What is the difference between multi port fuel injection and direct injection? With multiport fuel injection, fuel atomizes as it's sprayed into the intake port and then is pulled into the combustion chamber. With direct injection, the injectors are in the cylinder head and spray fuel directly into the combustion chamber, mixing with the air charge. What is the difference between MPI and GDI? Compared to conventional MPI engines of a comparable size, the GDI engine provides approximately 10% greater output and torque at all speeds. In high-output mode, the GDI engine provides outstanding acceleration. The following chart compares the...
