The main aim of this study is the experimental investigation of single cylinder DI diesel engine with and without coating. Diesel and radish (Raphanus sativus) oil Methyl Ester are used as fuels and the results are compared to find the effect of biodiesel in a thermal barrier coating engine. For this purpose, engine cylinder head, valves, and piston crown are coated with 100 lm of nickel-chromealuminium bond coat and 450 lm of TiO 2 by the plasma spray method. Radish oil methyl ester is produced by the transesterification process method. From the experimental investigation, slight increase in specific fuel consumption in thermal barrier coating engine is observed when compared with the uncoated engine, whereas NO x , HC, Smoke, and CO emissions decreased with coated engine for all test fuels used in the coated engine when compared with that of the uncoated engine.

A model of a liquid-phase membrane reactor is presented
here. The model utilizes a reaction
scheme and rate data applicable to the hydrocracking of California
Hondo crude derived
asphaltenes. Two reactor configurations have been investigated.
In the first reactor configuration (configuration A) the shell-side reactor volume is kept constant
by continuously pumping
into the reactor pure solvent. In the second reactor configuration
(configuration B) no additional
solvent is added to the reactor shell side, whose volume, as a result,
decreases as the solvent
and solutes diffuse across the membrane from the shell side to the tube
side. The model has
been utilized to identify optimal reactor and process conditions and
membrane characteristics,
which maximize conversion and product yields.
