12/16V4000G34F/G94F series engines are compact and powerful, reliable, easy to maintain and economic.
They comply with exhaust emissions standards US EPA Nonroad Tier 2 Compliant and NEA.
The required reduction of particle and pollutant emissions was achieved by using the following in-engine de-
sign technologies:
• Common rail system with HP injection
• Single-stage supercharging with two exhaust turbochargers
• Engine management with engine governor ECU 9
Common rail injection with up to 1800 bar injection pressure atomizes the fuel very finely to optimize com-
bustion. As a result, fuel consumption is improved and particle and pollutant emissions are reduced.
The engine governor ECU 9 controls and monitors the engine and supports emissions reduction through
monitoring and controlling emission-related variables.
The interaction of these technologies does not only reduce particle and pollutant emissions: The more effi-
cient, low-residue combustion process reduces fuel consumption and optimizes engine power.
