Title

STUDY OF THE EFFECTS OF ENGINE PHYSICAL PARAMETERS ON IGNITION DELAY

Pages

  213-224

Abstract

 The first period of combustion in a compression ignition engine is the period of IGNITION DELAY. The duration of this period plays an important role on performance and efficiency of the engine. Determination and control of parameters that effect the duration of this period is useful in design and improvement of engine performance. Tests were performed using full factorial design of experiments with engine speed in 4 levels: 1200, 1350, 1500, 1650 rpm, engine load torque in 4 levels: 55,70,85,100% and 5 levels of fuel injection timing 22, 27, 32, 37, 42°CA btdc on a small DIRECT INJECTION DIESEL ENGINE. Engine combustion parameters such as peak cylinder pressure, maximum rate of cylinder pressure rise, maximum acceleration of cylinder pressure, peak rate of heat release, cylinder internal temperature and static and dynamic IGNITION DELAY were measured and analysed. The effective parameters on IGNITION DELAY were determined and investigated which were cylinder internal temperature, engine speed and peak rate of heat release. Under constant condition of load and fuel injection timing, increasing peak rate of heat release cylinder internal temperature and engine speed, static and dynamic IGNITION DELAY were decreased. Under constant condition of load and speed, increasing peak cylinder pressure decreased IGNITION DELAY. The effect of cylinder pressure rise, maximum acceleration of cylinder pressure and engine load torque on IGNITION DELAY was negligible.
