Internal combustion engine training system is an educational unit featuring four different internal combustion engine types with a main purpose of testing the engine performance. It allows trainees to monitor the temperature and pressure during the engine operation. It also provides controlling the engine fuel type and calculating the engine efficiency

                                     
  • The trainer is to study the working principle of engine and its performance and characteristics.
  • The trainer mainly consists an operation unit and a load unit for prepared four-stroke movable engines.
  • The operation unit is used to operate the whole trainer, control it and has touch screen to demonstrate the process parameters.
  • The load unit is used to install and operate the engine modules.
  • The operation unit consists of a petrol tank, diesel tank, fuel test tank, fuel valves, air tank, water tank, water pump, fan, thermal resistance, screen, switches, sensors, LED indicators.
  • The load unit consists of a synchronous motor, load cell that are connected to the engine and a control panel for the engine connections.
  • The fuel test tank is at the side of the operation unit and intake fuel from the fuel tanks to the engine modules.
  • The trainer provides controlling the fuel type whether the engine is operated with petrol or diesel fuel.
  • The fuel test tank is split from the inside into two parts and connected with two valves for petrol and diesel fuel to control the flow of each one of them.
  • This tank contains two pressure sensors that are used to determine the fuel level required in the engine calculations.
  • The trainer is designed with two connections of inlet and outlet water to be connected to the engine for cooling.
  • The cooling water is driven by the pump from the cooling water tank to the engine module to cool it after combustion process, then the water returns to the operation unit to be cooled by the cooling fan, then back again to the water tank which makes a closed-loop cycle.
  • The engine is designed with an inlet air connection that is fed directly from the air tank.
  • The air tank contains a differential pressure sensor for measuring the air flow rate.
  • The thermal resistance is used to dissipate the power
  • The engine output power is converted to electric current that is consumed by the thermal resistance at the operation unit into heat to be dissipated to the surrounding air.
  • The sensors in the control panel record the exhaust temperature, oil temperature and pressure, fuel temperature,
    inlet/outlet cooling water temperature, air consumption temperature and allow analysis of the engine processes.
  • The touch screen provide an accurate reading of temperatures that are measured by highly sensitive sensors.
  • The trainer provides speed control and torque control as well as touch screen to present their controlled values.
  • The control unit includes ON/OFF main power switch and emergency switch.
  • The trainer is provided with software to demonstrate the measured values and draw experimental curves related to specific experiments.
  • The interactive software is designed to be helpful during experiments, by plotting necessary graphs, record readings and making calculations that verifies the performance of the internal combustion engine trainer.
  • The trainer is provided with two schematic diagrams to demonstrate the system operation.
  • The motor is coupled with the engine crankshaft that initiate the motion of pistons, thus the engine runs.
  • The load cell is 200 kg and takes place in the calculation process for obtaining the output power.
  • The trainer provides calculation of mass flow rate for fuel and the output power and key figures for engine efficiency.
  • The four internal combustion engines are (GX 270, GX 390, 1B 30, KAMA 186F). The trainer is used to illustrate each engine and how to control it.
