INTERNAL COMBUSTION ENGINE - ANALYSIS OF INTERNAL COMBUSTION ENGINE OF PERODUA MYVI 1.3 L K3-VE USING NUMERICAL METHODS

The engine for our group car model, MYVI 1.3 manual is 1.3 liter K3-VE engine
with four in-line cylinders that derived from Toyota Passo. This engine employs
Dynamic Variable Valve Timing (DVVT) systems and conventional electronic fuel
injection (EFL). DVVT improve engine dynamism, resulting in efficient fuel
consumption and cleaner gas emissions while EFL improves emission and
contributes to economical petrol consumption.K3-VE engine is a four-stroke
internal combustion engine with Otto cycle. There are some
descriptions about Otto cycle. Initially, both the intake and the exhaust
valves are closed, and the piston is at its lowest position (BDC). During the
compression stroke, the piston moves upward, compressing the air-fuel mixture.
Shortly before the piston reaches its highest position (TDC), the spark plug
fires and the mixture ignite, increasing the pressure and temperature of the
system. The high-pressure gases force the piston down, which in turn forces the
crankshaft to rotate, producing a useful work output during the expansion or
power stroke. At the end of this stroke, the piston is at its lowest position
(the completion of the first mechanical cycle), and the cylinder is filled with
combustion products. Now the piston moves upward one more time, purging the

exhaust gases through the exhaust valve (the exhaust stroke), and down a second
time, drawing in fresh air- fuel mixture through the intake valve (the intake
stroke).
