ENGINE DESIGN ANALYSIS PROJECT: HONDA CIVIC $1\mathrm{.}5$L ENGINE

Problem Statement: The HONDA CIVIC $1\mathrm{.}5$L ENGINE exhibits intermittent misfire issues, leading to compromised engine performance, increased fuel consumption, and elevated emissions. This complex engineering problem Is designed to diagnose potential root causes across the ignition, fuel, and sensor systems, often triggered under specific operating conditions by keeping your course outcome as design perspective. Identify and address the precise cause of misfires is essential to restore engine efficiency, reliability, and compliance with emissions standards to make a healthy environment $($SDGs$.)$

Figure $1$Basic information Objectives

Using the knowledge of internal combustion propulsion systems, students are required to analyze the engine design and performance of the HONDA CIVIC $1\mathrm{.}5$L ENGINE by completing the on$-$going design code. The design analysis must include the following aspects of the engine:

a$)$ Description of general construction including methods employed for control of pollutants in engine emissions.

b$)$ Solution of all possible general Operating characteristics.

c$)$ Solution of the relevant engine analysis for flow and performance parameters taking into account the effect of variable valve timings.

d$)$ Analysis of the air$-$fuel$-$injection $($AFI$)$ system.

e$)$ Estimation of the fuel combustion parameters for maximum and nominal chamber temperatures under stoichiometric and non$-$stoichiometric conditions.

f$)$ A step$-$by$-$step solution that includes all data tables and plots necessary to depict the engine parameters.

g$)$ A comprehensive solution on engine misfire issues which address the critical aspect of sustainable development goals$($SDGs$).\backslash$begin$\{$tabular$\}\{|$l$|$l$|$l$|\}$
