As a parent to our engines, Makita's mission is only fulfilled when we have supported each of them from creation to the end of a 30-year life. We work to provide services that exceed customer expectations, while also being a boon to our local community. 01 02. HPSCR . To HPSCR Manufacturing . 2021..

Selective Catalytic Reduction SCR NOx HPSCR : high -pressure SCR. N 2 . H 2 O .. SCR SCR Reactor . SCR is an exhaust gas treatment method in which the NOx generated in a marine diesel engine can be reduced into non-harmful nitrogen . and water catalytically. Ammonia which is generated from urea SCR . water is used as a reducing agent.. Urea solution A SCR system is located near the main engine on the upstream side of the turbocharger.

5 Since HPSCR is located at the upstream Including NOx side of the turbocharger, there is the feature that allows high temperature of exhaust gas Urea solution to be easily obtained.

6 SP E Exhaust Gas Recirculation Line up EGR .. NOx . EGR is a method in which part of the exhaust gas is recirculated to the scavenge air receiver after a cooling and cleaning process. In this recirculation, part of the oxygen in the scavenge air is . replaced by CO2 from the combustion process. Thus, it lowers the temperature peak of the combustion and therefore, reduces the formation of NOx. EGR . 2 . Bypass matching (EGRBP). 70cm 1 .. T/C cut-out matching(EGRTC). 80cm 2 .. Two different matching methods are used for the EGR system. Bypass matching (EGRBP). EGR with bypass configured with only one turbocharger and used for engines of bore 70 or less.
