engine braking fuel consumption

[Skywalker]

engine braking say 2500 rpm and acceleration with same rpm. do they consume equal amount of fuel? thanks

Sa old school diesel engine that uses injection pump, palagay ko pareho nga kasi ang dami ng fuel ay depende sa rotation ng injection pump.

Pero mas mainam pa ring iwasan ang engine braking depende na lang kung talagang kailangan like long down hill or nawalan ka ng preno.
