PART 1
Fuel Ejector:
An ejector is employed to reduce the leak-off pressure to the air pressure. The leak-off pressure fuel is received from the gadget (1.5 Bar), FIP metering valve (1.3 Bar), and CRDI Tube. it's a hollow box mounted around the mechanical device and therefore the comeback line is hooked up to the tank.
PCV (Positive Crank Ventilation)
This unit is employed to separated oil fumes from oil and send them back to the oil pan. this is often operated on the recent air cyclone from the manifold to the highest portion that separates the oil from air and air is distributed back to the housing.
POC DOC (Particulate chemical element Catalyst and Diesel oxidization Catalyst)
The unit is fitted at the piping before the silencer. The operation is to scale back the particulates and clean the exhaust gases before causation them into the atmosphere.
• Diesel oxidization catalyst (DOC): effective reduction of HC and CO some reduction of PM (reduction of VOF) typical PM reduction of 10-30%
• Particle oxidization catalyst (POC): initial target to extend particle deposition in oxidization catalyst while not a big backpressure increase. will scale back PM up to seventy-fifth.
Function of POC
POC is an associate degree open filter construction, consisting of furrowed stainless-steel fine screens that type a cylindrical substrate. Exhaust gas includes a free route to flow through the development, however a part of
particulates area unit treed within the screen "eyes".
• POC substrate is to be coated with a skinny wash coat layer as well as atomic number 78 metal.
• POC collects the soot and regenerates itself with the facilitation of NO2 throughout robust accelerations and main road driving. POC unit is to be put in invariably behind associate degree oxidization catalyst.
