Combustion estimation by cylinder vibration analysis on a supercharged IDI Diesel Engine- A comparative study with a new fuel as total replacement
Publication Date : 25/10/2017
In addition to the performance evaluation of the IDI engine with alternate fuel like waste cooking oil biodiesel, an attempt was made to evaluate the engine performance indirectly by measuring engine cylinder vibrations. The excitation for which is regarded as the very combustion itself in both the chambers. Especially the time waves recorded expressed ample evidence for the suitability in replacing the conventional fuel i.e. diesel fuel. Time waves are recorded in three directions forming two on the cylinder head and one on the foundation of the engine. The recordings are presented at full load on the engine with different fuels combinations. The investigation revealed that waste cooking oil with 6% hydrated methanol proved efficient booth in the wise of combustion propensity and torque conversion.
