Design of Experiment to Study The Effect of Mixing Nano-additive to Engine Oil on The Heat Transfer Performance

Project Overview

The primary assignment of the engine oil is to lubricate the metal parts of the engine. Engines normally fail due to lack of proper and efficient lubrication. The various failures include micro pitting, wear failure, thermal failure of lubricants, strength failure etc.

Nano-particles, such as TiO_2,CuO,PbS,ZnS, etc. Can be used as additives to lubricants for reducing friction and wear. Studies report that engine oil with Nano-particle additive delivers better friction reduction and anti-wear performance. Nano-fluid, formed by adding a small amount of Nano-particles into a fluid dispersant, may provide higher thermal conductivity and better lubrication in many applications. Applied in internal combustion (IC) engines, Nano-fluid has two benefits: improving tribological properties and enhancing heat transfer. The purpose of the project is to assess the feasibility of using Nano-fluid oil in IC engine. The engine tested in this work is a four-stroke, four-cylinder, water-cooled, spark-ignition engine. Its compression is 10.5 and fuel is supplied by a carburetor. During the test, the engine will be operated at 2500 rpm with no load for specific time. Nano-fluid will be added to the original lubrication oil to test the improvement in the performance of the engine.

Project Objectives

  • To design and implement a cross flow water-air radiator and oil-coolant for normal spark ignition (SI) engine.
  • To investigate the effect of using Nano-additive with oil engine and coolant  on the engine performance.
  • To study the enhancement of the rate of heat transfer in the engine oil and radiator when of Nano-particles is employed.
  • To compare the temperature variation of the fluids when pure gasoline verses biofuel/gasoline is utilized.
  • To assess the behavior of the engine performance  when different blends of biofuels are mixed with gasoline.
