The schematic diagram and the details of the test engine are given in the Figure 1 and Table 1 in details. Fuel flow rate is obtained by using the burette method and the airflow rate is obtained on the volumetric basis. NOx emission is obtained using an analyzer working on chemiluminescence principle.

Fig. 1. Experimental Setup

The particulate matter from the exhaust is measured with the help of the micro high volume sampler. AVL smoke meter is used to measure the smoke capacity. AVL DIGAS 444 {DITEST} five-gas analyzer is used to measure the rest of the pollutants. A burette is used to measure the fuel consumption for a specified time interval. During this interval of time, how much fuel the engine consumes is measured, with the help of the stopwatch. Regarding the fuel injection system, MICO plunger pump type fuel injection system is used in this experiment. All the measurements are collected and recorded by a data acquisition system.


The specifications of the engine are given below:

Eventhough emulsified fuel is much cheaper in cost, by considering the cost economics further cheaper based on the water addition: ethanol, surfactant, additive, water are having

In normal day by day experience, any technical knowledge person could understand / come across that, the direct corrosion for the petro products used engine. In addition to the pert products, above mentioned emulsified fuel and its based chemicals are having the properties to damage the engine and engine parts easily. Based on the above statement, it is

So, emulsified fuel is having the advantage of being solution for the depletion of fossil fuels, could be used directly to the current existing engine, easily available, bio products based, it having its own disadvantages of corroding the engine parts very easily. Particularly the minute parts like fuel injector, fuel injection system, filter, piston, cylinder etc., gets corrode rapidly with faster rate / easily and the every where the problem will be raised in future, if

Based on this, in this present work, making the above mentioned engine parts to be saved from the chemical corrosion from petro products based emulsified fuel by giving a Alodine EC ethanol corrosion resistant coating, with minimum level thickness to the emulsified fuel holding / carrying engine parts and the parts which is kept in contact with emulsified fuel.
