Features of C9.3 Diesel Engine
The engine assembly's base is composed of a heavy-duty cast iron cylinder block and air-orifice fuel injection system. This configuration allows for precision fuel delivery and mixture control. The block also features thick-walled sleeves and coolant passages to keep the engine cool and resilient in high-demand applications. The C9.3 is available in different configurations, including a two-valve or four-valve version.
The engine is also equipped with hardened steel fuel injectors, an electronic control unit (ECU) that offers precision fuel injection timing, and a turbocharger and wastegate for further optimization. When used with a suitable turbocharger, the engine assembly can reach a maximum torque of 1025 Nm. Additionally, it features high-flow intake valves, special pistons, an oil sump, and a heavy-duty crankshaft.
The C9.3 also includes Caterpillar's Advanced Combustion Technology (ACT), which offers improved fuel economy, reduced emissions, and superior torque delivery compared to older diesel engine designs. The engine assembly also meets the emission standards of the EU Stage IIIA and the U.S. EPA Tier 3 requirements.
As far as maintenance, the engine features a comprehensive set of filters and control systems to ensure that its fuel system remains clean and its components remain intact. The lubrication system also features a full-flow oil filter, heaters to keep the oil's temperature consistent, and a centrifugal filtration system.
The C9.3 is the ideal choice for industrial applications such as power generation, pumps, marine vessels, and rail and construction machinery. This engine offers reliable power and fuel efficiency without sacrificing performance, making it one of the most versatile options in Caterpillar's engine lineup.
