What is the definition of actual air-fuel ratio?
Technician A says that only offshore engines are permitted to use port-helix metering fuel systems on
EPA MY 2010 compliant and later engines. Technician B says that port-helix metering injection
pumps can be used on current diesel engines when the peak power rating is less than 70 BHP (52 kW).
Who is correct?
an engine is being discussed for lean running condition. technician A checks for air leak in the intake. Technician B checks for alcohol in the fuel. who is correct?
