A piston motion controller for a free-piston internal combustion engine is presented. To improve dynamic performance in the control of the piston motion and engine compression ratio, the controller response is determined from a prediction of engine top dead centre error rather than the measured value from the previous cycle. The proposed control approach showed superior performance compared wit...

This study presents an experimental and analytical investigation on the effects of using methyl ester linseed oil (MELO)-diesel blend B10, B20, B30 with hydrogen injection 5%, 10%, 15% in a VCR (Variable Compression Ratio) diesel engine, operated compression ratios (CRs) 15, 16, 17, 18 DFM (duel fuel mode). also gives emphasis optimized emissions CO, CO2, NO, smoke, when engine was MELO-diesel ...

Performance examinations of a dual-Diesel cycle engine in point performance characteristics such as exergy efficiency, power and density have been conducted. The effect design parameters the intake temperature, pressure, piston friction coefficient, average velocity, revolution, stroke length, residual gas fraction, pressure ratio, temperature compression ratio bore diameter to equivalence on a...

Vehicle Emission is one of the main causes of environmental damage. Vehicle engines produce carbon dioxide (CO2), hydrocarbon (HC), Nitrogen oxides (NOx) and many other harmful substances. An investigation was conducted using a compression-ignition engine fuelled with different ratios of blends of diesel and biodiesel at different EGR rates. The effects of different ratios of fuel blends and EG...
