A method for obtaining a mathematical model of an engine is proposed. The obtained model’s intended use is in the hardware-in-the-loop (HiL) real-time simulation modelling of the engine control system. The dynamic characteristics of the turbocharged diesel engine are described by differential equations of dynamic balance of the flows of mechanical energy and the gas mass in the main parts of th...

In this paper, a third order nonlinear model of the airpath of a turbocharged diesel engine is derived, which is then converted into linear parameter-varying (LPV) form with the intake and exhaust manifold pressure as parameters. The model predicts the mass air flow (MAF) and manifold absolute pressure (MAP) based on the EGR and VGT actuator positions, speed, and load. A comparison to experimen...

Further restrictions on the use of compression-ignition engines in transportation are prompting search for adaptations to run other fuels. One most popular alternative fuels is Compressed Natural Gas (CNG), which due its low carbon content can be competitive with classical This paper presents results testing a Cummins 6BT compression ignition engine that has undergone numerous modifications con...

Organic Rankine cycle (ORC) system is considered as a promising technology for energy recovery from the waste heat rejected by internal combustion (IC) engines. However, such waste heat is normally contained in both coolant and exhaust gases at quite different temperatures. A single ORC system is usually unable to efficiently recover energy from both of these waste heat sources. A dual loop ORC...
