Author: Daniel G. Teleoaca – Maritime Chief Engineer Foaming within the Exhaust Gas Recirculation (EGR) system of main engines is a critical yet often overlooked issue that can significantly impact engine performance, emissions control, and long-term reliability. This article provides a comprehensive, professional overview of the causes, effects, and remedies for foaming in EGR systems,…
The Exhaust Gas Recirculation (EGR) system is crucial for reducing NOx emissions in maritime engines by recirculating cooled exhaust gases, thus lowering combustion temperatures. It enhances compliance with IMO Tier III regulations and improves fuel efficiency but presents maintenance challenges. Robust practices are essential for optimal performance in modern shipping operations.
Author: Daniel G. Teleoaca – Marine Chief Engineer The world’s oceans are vital for global trade and transportation. But with great maritime activity comes a responsibility to minimize environmental impact. One key technology helping achieve this is Exhaust Gas Recirculation (EGR) for vessel engines. Let’s dive deep into the world of vessel engine EGR systems….
In the intricate world of marine engineering, the efficient operation of main engine air coolers and turbochargers is paramount to ensure the smooth functioning of a vessel’s propulsion system. These critical components are responsible for optimizing the combustion process and maintaining engine performance. To monitor and maintain these systems, marine engineers rely on essential instruments…
Author – Daniel G. Teleoaca – Marine Chief Engineer Understanding the Scavenging Air System The turbocharger uses the exhaust gas from the engine to compress new air and charge the engine with a positive pressure higher than ambient conditions. Exhaust gas temperature convection and compression raises the temperature of the air and this cannot be…
I believe that most of the marine engineers encountered, at least once in their career a turbocharger surging. This is not a pleasant experience, especially if you a in the close proximity of the turbocharger when at such happens, due loudly noise and backpressure effect. Turbochargers are designed to match the engine and balance the…
