Title

Assessment Of Effect Of Back Pressure And Gas Flow Dynamics Of Exhaust Pipe Of A Two-Stroke Engine On Its Performance Characteristics

Abstract

The dynamic effect of compression and expansion waves in the cylinder and exhaust system must be carefully managed through tuning for improved engine performance; empirical techniques have been used by authors to check the effects the geometrical dimensions of the exhaust system on the engine performance. Careful design of the exhaust and inlet manifolds enables the engineer to manipulate the engine performance characteristics. Engine performance characteristics are dependent on gas dynamic processes in the intake and exhaust systems as well as backpressure control. The geometrical configuration and optimization of the exhaust pipe system was designed with incorporation of divergent and convergent channels and analyzed with CAD and CAE at a speed of 10,000RPM and tuning of these geometric parameters of the exhaust pipe with respect to a two-stroke single-cylinder engine. This increase in the back pressure heralded from geometric tuning of the exhaust pipe leads to optimum engine performance characteristics. The torque and power characteristics can be ascertained from the airflow values of delivery ratio; trapping efficiency and charging efficiency were also deducted directly .simulation results were presented for air flow can be used to deduce the Peak power, specific fuel consumption improved exhaust emission characteristics, sound characteristics and smoothness. The configured exhaust system would be found to improve fuel economy of the engine and improve engine emissions, with an improved power output and noise reduction from the waves of the flow.

Key Words

geometrical tuning, divergent and convergent channels, back pressure effect, exhaust pipe system, improved engine performance characteristics
