Parametric Optimization Through Numerical Simulation of VCR Diesel Engine

Combine Effect of Variable Compression Ratio and Diffuser at Exhaust Manifold for Single Cylinder CI Engine using Diesel and Palm Biodiesel

“…In the experiment, four parameters is consider like as fuel (Diesel and Palm Biodiesel), Diffuser (No, Diffuser A, Diffuser B), compression ratio (18, 17, 16) and Load (1,7,13).From this parameter to Discuss Brake thermal efficiency, specific fuel consumption and NO X emission. This result discuss from the Minitab software Then Validation of Optimum set of Parameter.…”

“…There is a limit to very high pressures in the cylinder when diesel engine runon full load. Consequently, a high CR additionally impediment the measure of diesel fuel that can be injected at full payload [13]. In the VCR diesel engine, we could expand the compression ratio at start-up and low power and apply it to get steady start and lower the compression ratio when full power is required with a specific end goal to have the capacity to burn more fuel and make more power, yet at the same time having a reliable ignition.…”

Combine Effect of Injection Pressure and Diffuser at Exhaust Manifold for Single Cylinder CI Engine using Diesel and Palm Biodiesel

“…Exhaust manifolds are normally made from cast iron or stainless steel units which gain engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. The high pressure head is produce by the high pressure difference between the exhaust in the combustion chamber and the atmospheric pressure outside of the exhaust system [12]. The instantaneous |pressure evolution imposed by the manifold at the exhaust valve dependent essentially on the layout and |dimensions of the pipes, so that an adequate design of the manifold geometry can improve the engine power, efficiency, and decrease the emissions of pollutants.…”
