The main differences between the 12.7L Detroit Diesel and the 14.0L Detroit Diesel engines are:
-
Size and Displacement: The 14.0L engine has a larger displacement compared to the 12.7L engine. This means the 14.0L engine has larger components, such as a bigger cylinder bore.
-
Power Output: The 14.0L engine generally produces more horsepower and torque than the 12.7L engine. For example, the 14.0L engine can range between 425 and 515 horsepower, while the 12.7L engine typically produces around 400 horsepower.
-
Fuel Efficiency: The 12.7L engine is known for better fuel efficiency compared to the 14.0L engine. This is because the larger displacement of the 14.0L engine requires more fuel.
-
Weight: The 14.0L engine is slightly heavier than the 12.7L engine.
-
Emissions: The 14.0L engine, especially in later models, had to comply with stricter emission regulations, which sometimes affected performance and reliability.
Both engines are part of the Detroit Diesel Series 60 line and have their own advantages depending on the specific needs of the user. The 12.7L engine is often favored for its fuel efficiency and lighter weight, while the 14.0L engine is chosen for its higher power output and torque, making it suitable for heavier and more demanding applications.
