Why is Water/Methanol injection so effective on Diesels?
Unlike gasoline engines, the power in a turbo diesel is largely a function of fuel. The problem with continually adding fuel is that you create an over-fueling condition and reach a point where the exhaust gas temperatures become prohibitive (over 1300 degrees F). A 50/50 water/methanol mix will decrease EGT’s approximately 200-300 degrees F while increasing power 50-100HP.
Unlike gasoline engines, the power in a turbo diesel is largely a function of fuel. The problem with continually adding fuel is that you reach a point where the exhaust gas temperatures become prohibitive (over 1500 degrees F). A 50/50% Methanol/Water mix will decrease EGT’s approximately 250+ while increasing power 70-100HP. Power is increased through: a. Intake charge cooling – Water/methanol will lower air charge temps over 200f in this application. b. Methanol – this acts as a fuel as well as cooling the intake charge. Where else can you get this kind of power with cooler EGT’s!
