The OM 460 LA engine can be customized with various options to suit specific needs:
- Turbocharger Types: Different turbo configurations are available to optimize power, response, and fuel economy.
- Emission Packages: Options include EGR-only setups or combined EGR with SCR for enhanced emission control.
- Cooling System Modifications: Variations in radiator size and fan controls tailored to operating environments.
- Engine Brakes: Choices of exhaust brakes or compression release engine brakes (Jake brakes) for improved vehicle control.
- Power Ratings: Tuned for different horsepower and torque curves based on vehicle type or industrial use.
- After-treatment Systems: Diesel Particulate Filters (DPF) and other devices for compliance with environmental regulations.
- Turbocharged: A forced induction system that increases engine power by compressing intake air.
- Intercooled: Cooling the compressed air from the turbocharger to increase density and efficiency.
- Common Rail Injection: A fuel system where high-pressure fuel is supplied to injectors from a common rail for precise timing.
- EGR (Exhaust Gas Recirculation): A method to reduce nitrogen oxide emissions by recirculating exhaust gases back into the combustion chamber.
- SCR (Selective Catalytic Reduction): An after-treatment process using urea-based additives to reduce nitrogen oxides in exhaust.
- Jake Brake: A compression release engine brake system that helps slow heavy vehicles without using wheel brakes.
