A review of technical solutions for RCCI engines

Engines working in dual-fuel mode need special conditions to ignite air-fuel mixture without spark plug in a good moment with high combustion efficiency. To create homogenous air-fuel mixture the conditions in the cylinder are even more demanding. Many concepts of ignition was developed, but the most effective needs perfect mixing of fuel and air, which is a serious technical challenge. Technical solutions for dual-fuel engines cover the complexity of these problems thus leading to the further development of ignition systems in internal combustion engines. Fuel supply systems, the operation strategy of them, the shape of the combustion chamber are the most important elements to change and develop for correct operation of dual-fuel engines. The literature analysis showed a small amount of research carried out to optimize the operation of dual-fuel engines The variety of engines in which a dual-fuel system can be used requires much more research about them, and solutions necessary for their correctly operation.
