6D31-T

Mitsubishi 6D31-T Diesel Engine (Catalog 1987 HEO)

The Mitsubishi 6D31-T is a remarkable diesel engine that was first introduced in the catalog of 1987 under the Heavy Duty Engine Option (HEO) series. This engine, with its robust design and exceptional performance, has been a preferred choice for various industrial applications.

The 6D31-T is a 6-cylinder, in-line, direct injection, turbocharged diesel engine. It features a displacement of 31 liters (31,177cc), which makes it a powerful engine in its class. The engine block is made of high-strength cast iron for durability and resistance to wear and tear. The cylinder bores are lined with Nikasil, a nickel-silicon alloy, to ensure a long-lasting and efficient combustion process.

The engine employs a common rail direct injection system, which delivers fuel under extremely high pressure to each cylinder. This system allows for precise fuel control and optimizes combustion efficiency, resulting in reduced fuel consumption and lower emissions. The engine also comes equipped with an intercooler, which cools the compressed air before it enters the engine, improving combustion efficiency and power output.

The 6D31-T engine is turbocharged, meaning it utilizes a turbine driven by exhaust gases to force more air into the engine cylinders, which, in turn, increases the power output. The engine is also equipped with an electronically controlled fuel injection system, which allows for fine-tuning of the fuel injection parameters to optimize engine performance and efficiency.

The engine is designed to meet the rigorous demands of industrial applications. It boasts a maximum power output of 530 horsepower (395kW) at 1,800 rpm and a maximum torque of 1,520 Nm at 1,400 rpm. The engine's high power output and torque make it an ideal choice for heavy-duty applications, such as construction equipment, marine applications, and power generation.

The Mitsubishi 6D31-T engine is renowned for its durability and reliability, which is essential for industrial applications. Its robust design and high-quality components ensure that it can withstand the harsh operating conditions often encountered in industrial settings. Moreover, the engine is designed to be easily serviceable, with easy access to key components and a modular design that simplifies maintenance tasks.

In conclusion, the Mitsubishi 6D31-T diesel engine, as cataloged in 1987 under the Heavy Duty Engine Option (HEO) series, is a powerful and reliable engine that has been a preferred choice for various industrial applications. Its robust design, exceptional performance, and high power output make it an ideal choice for heavy-duty applications, such as construction equipment, marine applications, and power generation. The engine's common rail direct injection system, intercooler, and electronically controlled fuel injection system ensure efficient and optimized combustion, resulting in reduced fuel consumption and lower emissions. Its durability and reliability, coupled with its ease of serviceability, make the 6D31-T engine a top-tier choice for industrial applications.

The Mitsubishi 6D31-T engine, introduced in 1987 as part of the HE series, is a 3.0-liter, four-cylinder, intercooled common rail diesel engine.
