A1 Elmaihy, Ali T1 Experimental Investigations of Injection and Combustion Parameters of a Homogeneous Charge Compression Ignition (HCCI) Engine with a Multi-Injection Common Rail System JF Communications - Scientific Letters of the University of Zilina YR 2022 VO 24 IS 2 SP B120 OP B134 DO 10.26552/com.C.2022.2.B120-B134 UL https://komunikacie.uniza.sk/artkey/csl-202202-0016.php AB This work experimentally investigates the most imperative parameters that control the injection and combustion processes in a multi-injection HCCI Diesel engine namely; fuel-line pressure, timing of multi-injection events and the resulting in-cylinder pressure. These parameters in addition to the heat release rates are evaluated at different engine loads and speeds over up to 42 successive cycles. The main inter-relations of these parameters are also discussed.
