“…Study [15] presents a procedure of exhaust gas temperature measurements by thermocouples in turbocharged marine internal combustion engines. A linear parameter varying polytopic observer of the exhaust gases' pressure in turbocharged automotive diesel engine has been considered in [16]. In [17] the influence of the air pressure and air temperature after the turbocharger on the pressure in the cylinders of turbocharged a fourstroke diesel engine has been discussed.…”

The paper presents design and experimental investigation of an electronic system for control of the temperature of exhaust gases and the turbocharging air pressure in turbochargers of diesel automobile engines. The existing problems are faults in the fuel system of an engine. The indicators are changes in the values of the temperature and pressure in exact areas of the turbocharger. The presented device is a controller that monitors precisely the temperature and pressure, which are so vital for the long operation of the automobile. The control system is based on Arduino microcontroller. OLED Display has been added to visualize the obtained results. A schematic diagram of an electronic module for control of the temperature of exhaust gases and turbocharging air pressure in turbochargers of diesel automobile engines has been synthesized. The system has been investigated in laboratory conditions and practically implemented in a real automobile. As a result of laboratory experimental investigation, results were obtained for the time-monitored parameters temperature of the exhaust gases and turbocharging air pressure in the turbocharger system of a diesel automobile engine.

“…To balance the accuracy and complexity of control‐oriented diesel engine model, an alternative method is to model it with the methodology of linear parameter‐varying (LPV) [20–27]. The LPV model is expanded in the linear framework, considering the time‐varying parameter in the system [28–31]. The non‐linear system can be locally linearised by LPV.…”

This study presents an integrated control scheme of a diesel engine which aims to ensure quick torque response while limiting the average NOx emission below the certain specification. To start with, the sensitivity analysis is performed to recognize the key factors determined to balance emission, torque and fuel consumption. Considering the strong nonlinearity of the diesel engine, a multi‐input multi‐output (MIMO) linear parameter varying (LPV) model is developed. Unlike the conventional state‐depended LPV modelling process, the proposed LPV model is built based on a kernel function with a novel form of state‐free predictive equation so that the system outputs are directly computed. The control objective of coordinating torque tracking and emission reduction is then accomplished by designing a model predictive controller that regulates the fuel injection quantity, fuel injection angle, exhaust gas recirculation (EGR) rate and the opening degree of variable geometry turbine (VGT) valve. Finally, the developed LPV model and the MPC controller are testified with a high‐fidelity commercial diesel engine model. The results show that the LPV‐MPC controller is able to satisfy the NOx emission specification and the engine torque tracks the desired reference fast in transients, while the control variables are suitably actuated within the actuator constraints.
