- Engine Type:Four-cylinder, naturally aspirated, turbo-diesel engine.
- Displacement:Approximately 3.9 liters.
- Turbocharger:A device that forces more air into the combustion chamber, increasing power and torque output.
- Dual Filter:This refers to having two filters, often a fuel filter and an oil filter, or two fuel filters. This provides a higher standard of filtration, protecting the engine from impurities and ensuring longer life.
- Application:The 4D105 engines are used in a variety of heavy equipment and construction vehicles.
The KOMATSU 4D105-2 Turbo engine is a water-cooled, 4-cycle, 4-cylinder, in-line diesel engine with a 105mm bore and 115mm stroke, for a displacement of approximately 3.0 liters or 3053cc. Its dual-filter system typically includes a full-flow oil filter to protect internal engine components, and the engine is often paired with a multi-stage air filtration system, which may use a fuel filter. For complete dual-filter specifications, you would need to consult the specific engine service manual, as the filtering systems can vary depending on the machine it is installed in.

The precise filters used on a 4D105-2 engine will vary based on the specific piece of equipment. To determine the exact filters for your machine, you should:
-
1. Identify the machine:
Find the model and serial number of the Komatsu equipment the engine is installed in (e.g., a Komatsu 510).
-
2. Consult the service manual:The official service manual for that equipment will provide the exact part numbers and specifications for the dual-filter setup.
