What is EMD 645 Diesel Engine ?
The EMD 645 is a family of diesel engines designed and manufactured by Electro-Motive Diesel (EMD), a subsidiary of Progress Rail Services Corporation, which is itself a subsidiary of Caterpillar Inc. The EMD 645 series was first introduced in the 1960s and has been widely used in various applications, including locomotives, marine vessels, and stationary power generation.
The EMD 645 engine is a two-stroke, V-type, 45-degree angle engine with a 9.0625-inch (230.2 mm) bore and a 10-inch (254 mm) stroke. It is available in different configurations, with the number of cylinders varying from 8 to 20, depending on the application and power requirements. The engine is known for its durability, reliability, and ease of maintenance, making it a popular choice in the rail and marine industries.
Key features of the EMD 645 diesel engine include:
- Two-stroke cycle: The two-stroke cycle provides a power stroke for each revolution of the crankshaft, resulting in higher power output and better fuel efficiency compared to four-stroke engines of similar size.
- Turbocharging: EMD 645 engines are typically equipped with turbochargers to increase power output and efficiency by utilizing the exhaust gas energy to compress intake air.
- Mechanical fuel injection: The engine uses a mechanical fuel injection system to deliver precise amounts of fuel into the cylinders for optimal combustion and performance.
- Modular design: The engine components are designed with modularity in mind, making it easier to service, maintain, and replace parts as needed.
- Versatility: The EMD 645 engine series can be configured to meet various power requirements and is suitable for a wide range of applications, including locomotives, marine propulsion, and stationary power generation.
Overall, the EMD 645 diesel engine is a robust and reliable power source that has been widely used for decades in various industries due to its proven performance, durability, and versatility.
