Reactivity Controlled Compression Ignition (RCCI) is commonly mentioned as a potential efficient and clean combustion concept. This study makes the first evaluation of natural gas-diesel RCCI combustion for mid-speed marine engines. A state-of-the-art dual-fuel engine with 350 mm bore diameter is the basis for numerical simulations. GT-Power is...

Low-temperature combustion in reciprocating engines appears to be a cutting-edge technology which ensures extremely low emissions of nitrogen oxides and particulate matters in parallel with high fuel efficiency. This mode of combustion can be realized in homogeneous charge compression ignition engines. However, this technology poses challenges,...

Controlled auto-ignition (CAI) is an advanced combustion technology offering high thermal efficiency and low NOX emissions. One promising approach to achieve CAI combustion is application of negative valve overlap resulting in internal exhaust gas re-circulation. However, combustion control is still an issue which should be resolved before wide...

One of the pending issues regarding Homogeneous Charge Compression Ignition (HCCI) engines is high load operation limit constrained by excessive pressure rise rates (PRRs). The present study investigates various measures to reduce combustion harness in a residual-affected HCCI engine. At the same time, the impact of those measures on efficiency...

Homogeneous charge compression ignition concepts despite high efficiency and ultra-low nitrous oxides emissions, suffer from week controllability and load range limited by excessive pressure rise rates. In the present work, controlled auto-ignition is achieved via direct injection of gasoline into the exhaust gasses recompressed during negative...

In the present paper, laboratory produced, animal origin biofuels (swine lard and turkey lard had been used as raw material for biofuel production) were evaluated in terms of physicochemical parameters and compared with commercial mineral diesel fuel and its mixture with rapeseed oil methyl esters. Basing on the results of physicochemical...

This study discusses the model of operation of a dual-fuel compression-ignition engine, powered by gaseous fuel with an initial dose of diesel fuel as the ignition inhibitor. The study used a zero-dimensional multiphase mathematical model of a dual-fuel engine to simulate the impact of enhancing Natural Gas (NG) with other gases on the...
