Displacement: The 4BTA3.9-C has a displacement of 3.9 liters, which refers to the total volume of air and fuel that can be drawn into the cylinders during one complete combustion cycle.
Configuration: It is a four-cylinder engine, meaning it has four individual cylinders arranged in a line or in a 'straight-four' configuration. This design provides a good balance between power output and compactness.
Turbocharged: The engine features a turbocharger, which is a device that compresses the incoming air, allowing more oxygen to be available for combustion. This results in improved engine performance and power output.
Aftercooled: The 4BTA3.9-C is also equipped with an aftercooler, or charge air cooler, which cools down the compressed air from the turbocharger before it enters the combustion chambers. Cooling the air increases its density, further improving engine efficiency and power.
Power Output: The engine produces a maximum power output of approximately 105-130 horsepower (78-97 kilowatts), depending on the specific application and configuration. This makes it suitable for a variety of uses, from light-duty to medium-duty applications.
Fuel System: It features a direct injection fuel system, where fuel is injected directly into the combustion chambers at high pressure. This provides better fuel atomization and more efficient combustion, resulting in improved fuel economy and reduced emissions.
Cooling System: The engine is equipped with a liquid cooling system, which uses a mixture of water and coolant to maintain optimum operating temperatures. The cooling system ensures that the engine remains within its optimal temperature range, preventing overheating and ensuring longevity.
Lubrication System: The 4BTA3.9-C employs a full-flow, spin-on oil filter and a gear-driven, positive displacement oil pump to provide proper lubrication to all moving parts.
This helps reduce friction, heat, and wear, enhancing the engine's durability and reliability.
Emissions: The engine is designed to meet various emissions regulations, such as EPA Tier 3 and EU Stage IIIA. It incorporates technologies like high-pressure fuel injection and optimized combustion to minimize harmful exhaust emissions and contribute to a cleaner environment.
Serviceability: The 4BTA3.9-C is designed with serviceability in mind, featuring easily accessible maintenance points, such as the oil filter, fuel filter, and air filter. This simplifies routine maintenance and reduces downtime.
