Module 10 | Mechanic Diesel trade theory | Multiple choice questions discussion

🎯 ITI Mechanic Diesel Trade Theory CBT Exam Preparation | Module 10: Emission Control Systems & Marine Engines Welcome back to our ITI Mechanic Diesel question bank series! In this session, we break down Module 10, covering Emission Control Systems and Marine Engines (ఉద్గార నియంత్రణ వ్యవస్థ & మెరైన్ ఇంజన్లు). This module bridges the gap between modern environmental standards and the specialized heavy engines used in maritime applications, making it a highly important section for your trade theory exam. If you are preparing for your upcoming Computer Based Test (CBT) or practicing on the NIMI Mock Test platform, this video will help you secure full marks! We explain every multiple-choice question (MCQ) from the official NIMI question bank with clear, practical breakdowns. 📌 What You Will Learn in This Video: Vehicle Emission Standards: Understanding Euro and Bharat Stage (BS) emission norms, and sources of engine pollutants (CO, HC, NOx, and PM). Exhaust After-Treatment Systems: Detailed working of Catalytic Converters (Oxidation and Reduction), Diesel Particulate Filters (DPF), and Selective Catalytic Reduction (SCR) using Diesel Exhaust Fluid (DEF/AdBlue). EGR System Recalibration: How Exhaust Gas Recirculation reduces combustion temperatures to control NOx emissions. Introduction to Marine Engines: Main differences between automotive and marine diesel engines, including constructional features and heavy-duty designs. Marine Engine Support Systems: Understanding marine engine cooling (heat exchangers, seawater circuits) and unique marine propulsion/reversed gear mechanisms. 🛠️ Useful Resources for ITI Students: Official NIMI Mock Test Website: https://nimimocktest.in Download Study Material & PDFs: https://bharatskills.gov.in 📢 Don't forget to Like, Share, and Subscribe!
