4BT Engine Advantages Below, we’ll spell out the distinct traits that continue to keep the 4BT in high demand.
1)Diverse engine configurations
The 4B series engine has many versions. Among the 3.9L 4-cylinder engines, there are 4B3.9/4BT3.9/4BTA3.9, and the power of the 4BT engine can range from 60 horsepower to 140 horsepower. Torque can range from 200 lb-ft to 350 lb-ft. Turbocharged models increase the engine’s air intake, improving engine efficiency and torque.
2)Wide application of 4BT series engines
The 4BT series diesel engines are widely used and can be used in generator sets, agricultural equipment, construction machinery, trucks and ships, etc. At the same time, they can also be seen in jeeps, SUVs, sedans, Land Rover trucks, etc. Whether in terms of physical size, power, or reliability, the 4BT series engines are ideal for a variety of vehicle applications.
In the automotive industry, 4BT diesel engines are also famous for their use in school buses, vans, and other commercial vehicles. Among them, automotive engines are usually paired with automatic or manual transmissions.
3)Easy after-sales maintenance
The 4BT uses the same connecting rods, pistons, injectors, and valve train components as the 6BT, making these parts very easy to find and replace, and low-speed operation also extends the service life. Cummins produces a lot of flywheel housings and flywheels of different sizes, which provides more possibilities for engines with different applications.
For example, alternators, starters, exhaust pipes, superchargers, fuel injection pumps, etc., these accessories are easy to find in the aftermarket. The 4BT engine has the advantages of long service life and easy maintenance.
4)Mechanical simplicity
The B series engines, especially the 4BT engine, use mechanical pumps. The engine is gear-driven oil pumps, camshafts, fuel injection pumps and accessory drive systems, which means there are no timing belts or chains on the 4BT engine. In addition to no moving parts, the 4BT also has almost no electronic equipment. The engine base is all that is needed to get the engine running. The power supply of the starter, solenoid valve and alternator completes the requirements of igniting (and shutting down) the 4BT. This makes this engine easy for every user to use.
