Experimental study and analysis of lubricants dispersed with nano Cu and TiO2 in a four-stroke two wheeler.

Sarma PK, Srinivas V, Rao VD, Kumar AK - Nanoscale Res Lett (2011)

Bottom Line: The empirical relation correlates with the observed data with reasonable accuracy.Further, extension of the analysis by developing a mathematical model has revealed a definite improvement in brake thermal efficiency which ultimately affects the fuel economy by diminishing frictional power in the system with the introduction of nanoparticles into the lubricant.The performance of the engine seems to be better with nano Cu-Racer-4 combination than the one with nano TiO2.

ABSTRACT
The present investigation summarizes detailed experimental studies with standard lubricants of commercial quality known as Racer-4 of Hindustan Petroleum Corporation (India) dispersed with different mass concentrations of nanoparticles of Cu and TiO2. The test bench is fabricated with a four-stroke Hero-Honda motorbike hydraulically loaded at the rear wheel with proper instrumentation to record the fuel consumption, the load on the rear wheel, and the linear velocity. The whole range of data obtained on a stationery bike is subjected to regression analysis to arrive at various relationships between fuel consumption as a function of brake power, linear velocity, and percentage mass concentration of nanoparticles in the lubricant. The empirical relation correlates with the observed data with reasonable accuracy. Further, extension of the analysis by developing a mathematical model has revealed a definite improvement in brake thermal efficiency which ultimately affects the fuel economy by diminishing frictional power in the system with the introduction of nanoparticles into the lubricant. The performance of the engine seems to be better with nano Cu-Racer-4 combination than the one with nano TiO2.

Figure 1: Motorbike mounted on roller test bench.

Mentions: A hydraulic dynamometer arrangement loads the rear wheel, and its magnitude is measured with the aid of proper digital measuring device at a specific rotational speed. The fuel line to the engine is through a digital measuring device to register fuel consumption rate with good accuracy. Under running conditions, a blower is used to blow air over the finned surface of the cylinder to cool the engine-simulating actual road conditions. The cooling arrangement is made to reduce the heat buildup in the engine, preventing adverse effects on lubrication and hence the mileage. The photographic view of the rig with motorbike in position is shown in Figure 1.
