Ford Diesel Engine History

Ford has a long and illustrious history in the world of diesel engines. It all started in the 1980s when Ford introduced its first diesel engine, the 6.9L V8 International Harvester IDI (Indirect Injection). This engine was known for its reliability and durability, making it a popular choice among truck owners. In 1994, Ford introduced the 7.3L Power Stroke V8 engine, which quickly became a legend in the diesel community. Its reputation for robustness and power made it a favourite among truck enthusiasts.

In 2003, Ford replaced the 7.3L Power Stroke with the 6.0L Power Stroke V8 engine. While this engine offered improved power and fuel efficiency, it was plagued by reliability issues, particularly with its fuel injectors and EGR (Exhaust Gas Recirculation) system. Despite these problems, the 6.0L Power Stroke remains a popular choice for those willing to invest in aftermarket upgrades to address its weaknesses.

Ford made significant improvements with introducing the 6.4L Power Stroke V8 engine in 2008. This engine featured a twin-turbocharger system and a redesigned fuel injection system, providing increased power and efficiency. However, it still had some reliability concerns, primarily related to its emissions control systems.

In 2011, Ford introduced the 6.7L Power Stroke V8 engine, which marked a turning point for the company. This engine was designed in-house by Ford and addressed many of the reliability issues of its predecessors. The 6.7L Power Stroke is known for its impressive power, fuel efficiency, and durability, making it one of the most reliable Ford diesel engines.
