TEMPERATURE EXHAUST GAS ANALYSIS ON THE SHIP ENGINE

Rekayasa Mesin, 2022
Dual-fuel diesel engine is an engine with the use of two fuels in the combustion process to get labor on the engine. The types of fuels used include methane gas and marine gas oil fuels.

Study on the knock phenomenon on a dual-fuel engines using renewable fuel bioCNG/diesel

Tạp chí Khoa học và Công nghệ
The article focuses on researching and evaluating the effect of knocking in biomethane/diesel dual-fuel operating modes. Knocking occurs because part of the biomethane fuel is compressed at high temperatures and pressure.

Retrofitting a high-speed marine engine to dual-fuel methanol-diesel operation: A comparison of multiple and single point methanol port injection

Fuel Communications, 2021
As a result of climate change and increasingly stringent emission legislation the shipping industry has started with a transition to sustainable propulsion. Methanol is a viable fuel to reach this goal: it is a great engine fuel (high octane number, high

Effects of combining EGR and supercharging on the combustion characteristics of a diesel dual fuel engine with induced natural gas

Nihon Kikai Gakkai ronbunshu, 2018
This paper describes the results of a combination of EGR and supercharging applied to a diesel dual fuel (DDF) engine using natural gas (CNG) introduced from an intake pipe. The oxygen concentration in the intake charge were varied from 21% (without EGR)

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Economical and environmental assessments of compressed natural gas for diesel vehicle in Thailand [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
The economic assessments for the use of compressed natural gas as fuel for several types of diesel vehicles, rarely pick up, non-fixed route truck and private truck, were studied. It is noted that two main technologies of diesel natural gas vehicle (NGV),
