A STRAIGHT 6 IS THE CORRECT DIESEL LAYOUT
for motor vehicle use save for the straight 5 in Mercedes cars.
the geometry of this motor is perfect for diesel engine design
An old truck driver told me this.
Why are all Class 6 – Class 9 commercial diesel truck engines straight sixes?
CAT, Cummins, International and others?
Why was the Dodge Cummins 5.9 TD a straight six?
A V engine doesn’t lend itself well to diesel designs for on-highway use.
Something to do with physics and the chemistry of diesel combustion.
V-shaped diesel engines at 45 degrees are great for railroad use however and railroads have been using them for nearly 100 years.
A 90-degree diesel V motor is a definite no-no in internal combustion engineering.
