DPF*1

collect PM※(SOOT)

The minuscule amount of PM in the emissions gas is captured by the Diesel Particulate Filter (DPF), preventing its escape into the atmosphere and resulting in unparalleled environmental performance.

Cooled EGR

Decreased NOX by recirculating gas emission

An Exhaust Gas Recirculation (EGR) system partially cools the exhaust gas and mixes it with suction air and circulates it within the cylinder. This process lowers the burning temperature inside the cylinder and decreases nitric oxide (NOX). The EGR valve controls the circulating amount of EGR depending on the density of the intake oxygen which reacts to the suction temperature and altitude. It allows a stable combustion control of fuel in every working conditions.

Common rail system

Control fuel injection with a electric control

The Tier 4 engine uses a fully electronically controlled common rail and fuel injection system. At ignition, the system instantaneously collects and analyzes information such as the outside temperature and altitude (the air’s oxygen concentration level), engine load conditions and DPF temperature for precise control of the fuel injection timing, fuel quantity and number of injection times for combustion control down to the millisecond that in turn reduces PM and NOX emissions.
