General Information
Equipped with an overhead valve and turbocharger, Hyundai
Doosan Infracore diesel engines are electronically controlled
and air-cooled by a cooling fan.
Pressurized fuel generated by the high-pressure fuel pump
is stored in the common rail. When the operator uses the
generator, the optimal amount of fuel and fuel injection timing
are determined based on the data set in the electronic control
unit (ECU) according to the vehicle speed and operating
conditions, while the ECU actuates the solenoid valve for the
injector installed in each cylinder of the engine to inject fuel
into the cylinders.
The crankshaft is a single forged unit. The oil seals on the
crankshaft and flywheel are designed to prevent oil from
entering the flywheel.
The connecting rod is a single forged unit. Its big end can be
disconnected in the vertical direction, enabling it to be
removed with the piston through the top of the cylinder. The
moving parts of the crankshaft and connecting rod are
equipped with alloy bearings.
