Abstract

A blend of diesel fuel and corn oil in the ratio of 80:20 (v/v) is prepared. 1-butanol and 1-pentanol are mixed separately with the binary blend in different ratios (4:96, 7:93, and 10:90 v/v) to prepare ternary blends. Pure diesel fuel and ternary blends are tested at various engine speeds (1000–2500 rpm) and at full throttle position. A regression model and its trigonometric Fourier series are proposed to represent the variation of in-cylinder pressure vs. crank angle measured by the author. The regression model and its Fourier series are compared to the Gaussian function of second-order using the in-cylinder pressure data measured by the author and different authors. On average, the ternary blends have lower brake effective efficiency (0.7347 % -4.0553 %) and peak heat release rate (5.1113 % -6.3083 %), compared to diesel fuel. On average, the ternary blends have a shorter combustion duration (0.4045 % -7.0236 %) and longer ignition delay (8.3635 % -13.9110 %) relative to diesel fuel. The ternary blends produce lower CO (8.4769 % -13.1598 %), HC (30.0073 % -36.2523 %), and smoke (4.8566 % -7.4181 %) emissions while higher NOX (3.2691 % -10.8795 %) emission. The estimated values from the proposed regression model and its Fourier series coincide quite well with in-cylinder pressure data measured by the author and different authors.
