In conjunction with the test stand, which includes a drive and brake unit, the four-stroke diesel engine is highly suitable for use in teaching the fundamentals of engine functioning and measurement. It is part of a series of devices enabling experiments to be performed on engines and machines.
Learning Objectives/Experiments:
Determination of volumetric efficiency and lambda
Determination of the frictional power of the engine
Plotting of torque and power curves
Determination of specific fuel consumption.
Biodiesel is simple to use, biodegradable, and essentially free of sulfur and aromatics. engine test stands are available with or without dynamometers. It can be used in compression-ignition (diesel) engines with little or no modifications. Students can make their own fuel, conduct engine performance and emission measurements. As pan of it's alternative fuels program, introduced this biodiesel program which includes the dynamic performance of biodiesel engines with its patented electric. Biodiesel Engine Program contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. The user has the choice to order either an electric of up to 8 HP or a hydraulic closed-loop, up to 600 HP.

Common Rail Diesel Engine Management System demonstration panel shows the operating of the electronic, mechanic and hydraulic elements that constitute the control and fuel feed system of the contemporary CR/EDC ignition diesel engine.
The Common Rail Diesel Engine Management System is composed of two main modules:
The fuel system enables presentation of the sub-assemblies working and a change of the fuel dose. The pump drive control allows the simulation of the full rotational speed range from the start phase to full capacity. The fault simulation console enables creating of breaks in chosen circuits and observing the reaction of the control system to the occurred position. The measuring panel enables easy installation of the check meters for all the system sensors and working sub-assemblies.
Diesel Common Rail engine control unit, equipped with a microprocessor controller used for the demonstration of the high-pressure pump and electro-injector control system. The module can only work with the pump and injector control module.
Common rail pump and injector control system for demonstration of its working and for the study of the electric and hydraulic parameters of the high-pressure pump and electro-injector control system. The module can work autonomously or together with the Diesel Common Rail engine electronic control unit.

In conjunction with the load unit, the test engine is a complete engine test stand. The connection to the brake is made via a rotationally elastic coupling with a jointed shaft. The engine is attached to the load unit by fasteners. The engine used here is a four-cylinder diesel engine. It has its own closed cooling water circuit. A solid welded frame on rollers, with a vibration-insulated base plate, carries the entire setup. Hazardous areas such as hot surfaces and rotating parts are covered with perforated plates.
Learning Objectives/Experiments:
In conjunction with load unit
Energy balances
Overall engine efficiency
Plotting of torque and power curves
Determination of volumetric efficiency and lambda (fuel-air ratio)
Determination of specific fuel consumption.
In the conventional diesel engine the rotation speed of the engine controls the pressure to the injectors and, furthermore, pressure and injection are strictly correlated, because only when the pressure exceeds a given threshold there is the mechanical opening of the injector. Common Rail Direct Injection For Diesel Engine simulator allows the study, the testing and the troubleshooting on HDI (CDI CR) injection systems for diesel engines that, similarly to what happens for the traditional injection petrol engines where, however, the pressure of the fuel is only few bars, use a high pressure electric pump and a single manifold to connect the pump to the electro-injectors, which are electronically and individually controlled for what concerns the start and the duration of the injection.
The advantages of the Common Rail Direct Injection For Diesel Engine:
High pressure also at low regimes
Reduction of the noise
Reduction of the consumptions and of the emissions.
Excellent atomization and dispersion of the fuel
Increase of the torque
The main components that characterize a Common Rail Direct Injection For Diesel Engine are the following:
Common rail with electro-injectors, fuel pressure limiting valve and relevant pressure sensor
Electronic control board for the management of the whole plant
Fuel tank with pre-filter
High pressure electro-pump
Flow limiter
Engine rpm sensor
Accelerator pedal position sensor
Over supply pressure sensor
Computerized workstation linked to the management system.
Pneumatic actuator for the variable geometry turbine
Air temperature sensor
Air mass sensor
Engine temperature sensor.
The program consists of a trainer built with genuine equipment and educational materials to teach the fundamentals of Common Rail fuel injection and engine control. The electronics are faulted in order to create problems in the fuel system for student diagnosis and practice. Cummins Diesel Trainer is constructed from a Cummins type vehicle, using an electronically controlled Diesel fuel injection.

Biodiesel Process Trainer PLC Controls provides students the opportunity to gain real operating experience focusing on all aspects of biodiesel production the chemical process, control strategy, and management of the chemical process. The Biodiesel Process Trainer is a pilot-scale plant that demonstrates both batch and semi-continuous conversion of vegetable oil feedstock into biodiesel. The Biodiesel Process Trainer has instrumentation to provide for control of all process flows, temperatures and levels.
Function:
The rate of reaction is influenced by several factors including temperature and degree of mixing. The Biodiesel Process Trainer is designed and built for instructional use and includes many student-friendly features. The conversion of triglycerides into biodiesel is normally performed by base-catalyzed conversion. This reaction takes place at modest conditions of temperature and pressure and can produce conversion rates over 98%. This highly flexible process trainer incorporates various commercially available mixing technologies and process configuration options to allow for the comparative analysis of the technologies currently available in the biodiesel industry. The main reaction vessel is constructed from industrial glass allowing the students to visually monitor the trans-esterification process.
