“…Experimental results show that Hydrocarbon (HC) and Carbon Monoxide (CO) emissions were reduced, and BTE was increased by 1.6%. 6 Murari et al reviewed and stated that surface texture parameters such as geometry, dimension, motion parameters, and surface roughness impact IC engine performance. 7 Ekrem Buyukkaya and Cerit used the 3D finite element method to examine the temperature distribution of normal and thermal barrier-coated pistons.…”

This research presents an experimental and theoretical evaluation of the effect of poly-composition thermal barrier coatings on the performance and emission characteristics of the compression ignition engine. This work investigated the thermal and physical behavior of thermal barrier coating. The thermal barrier coating was coated into two layers, and the thermal plasma spray method was used to make the coating. The first layer is AT13, and the top layer is Yttria-stabilized zirconia. The coated and uncoated pistons were analyzed in the Ansys, and it has shown the temperature distribution of the pistons. The experimental report shows that the brake thermal and volumetric efficiency was increased by 7.52% and 1.06%, brake-specific fuel consumption was reduced up to 18.91%, emission of carbon monoxide was reduced by 50%, and hydrocarbon was reduced by 52.38%.

This study investigates the effect of oil viscosity on pollutant emissions and fuel consumption of an internal combustion engine (ICE) at high altitudes using a response surface methodology (RSM). A Chevrolet Corsa Evolution 1.5 SOHC gasoline engine was used in Cuenca, Ecuador (2560 m above sea level), testing three lubricating oils with kinematic viscosities of 9.66, 14.08, and 18.5 mm2/s, measured at a temperature of 100 °C under various engine speeds and loads. Key findings include the following: hydrocarbon (HC) emissions were minimized from 150.22 ppm at the maximum load to 7.25 ppm with low viscosity and load; carbon dioxide (CO2) emissions peaked at 15.2% vol with high viscosity and load; carbon monoxide (CO) ranged from 0.04% to 3.74% depending on viscosity and load; nitrogen oxides (NOx) were significantly influenced by viscosity, RPM, and load, indicating a need for model refinement; and fuel consumption was significantly affected by load and viscosity. RSM-based optimization identified optimal operational conditions with a viscosity of 13 mm2/s, 1473 rpm, and a load of 78%, resulting in 52.35 ppm of HC, 13.97% vol of CO2, 1.2% vol of CO, 0 ppm of NOx, and a fuel consumption of 6.66 L/h. These conditions demonstrate the ability to adjust operational variables to maximize fuel efficiency and minimize emissions. This study underscores the critical role of optimizing lubricant viscosity and operational conditions to mitigate environmental impact and enhance engine performance in high-altitude environments.

Nanoparticles, which are particles with dimensions on the nanoscale, have a wide range of applications across many different fields. Nanoparticles are used in many fields, such as electronics, medicine, cosmetics, manufacturing, and materials science. They have unique properties such as a high surface area-to-volume ratio, high reactivity, and the ability to interact with biological systems. In this chapter, the applications and effects of nanoparticles in conventional—Lathe, Grinding, Milling, and drilling processes—and unconventional machining processes—electro-chemical machining, electro-discharge, ultrasonic, abrasive waster-jet machining—processes are illustrated. Special applications of nanoparticles in medicine, agriculture, food, construction, biotechnology, and IC engines have also been discussed. The limitations of using nanoparticles in engineering applications have also been explained.
