The diesel engine is an internal combustion engine in which ignition of the fuel which is injected into the combustion chamber is caused by the elevated temperature of the air in the cylinder due to mechanical compression. Diesel engines work by compressing only the air and contrasts with spark-ignition engines such as petrol engine or gas engine, which use a spark plug to ignite an air-fuel mixture. They have the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engines. Diesel engines may be designed as either two-stroke or four-stroke cycles and they are used in submarines, ships, locomotives, trucks and heavy equipment. They will continue to be viable for the near future for several reasons. Primarily, diesel models will continue to account for the overwhelming majority of global medium and heavy motor vehicle engines because they offer greater torque, and are more durable and fuel-efficient than comparable gasoline engines. They also have a longer lifespan, lower maintenance requirements, and higher residual value. Second, diesel engine fuel is less expensive than gasoline in numerous countries, helping make diesel light vehicles popular in these areas. Third, while electric and hybrid vehicles are expected to capture market share from diesel models in mature markets with demanding emissions regulations, this will only have a limited impact on demand at the global level. The infrastructure required for widespread electric vehicle is still lacking in most countries and will take years to develop. Advanced diesel models can also get better mileage than some gasoline-electric hybrid vehicles. De Lorenzo proposes for this category a simulator that allows for a complete and easy learning of the techniques used in the electronic injection systems of the Diesel engines and reproduces a turbo-diesel injection system for heavy vehicles. It is supplied with a CAI software and fault simulator for troubleshooting. It is recommended for professional institutes, vocational schools and technical colleges.
The simulator panel is purposely designed and realized to allow for a complete and easy learning of the techniques used in the electronic injection systems of the Diesel engines.
In particular, this simulator panel reproduces a turbo diesel injection system with electronically controlled in line injection pump for heavy vehicles (lorries, buses, agricultural machines).
The simulator provides realistic fault finding facilities using heavy vehicle schematic diagrams.
An easily understood schematic system represents the starting and fuel injection systems of a typical heavy vehicle.
The student can see the exact operation of the various circuits as used in trucks and buses and can gain a hands-on introduction to each of the components and devices found in typical heavy vehicle systems.
All practical activities can be carried out using the electrical/electronic circuits and devices mounted on the panel trainer.
• Dim. mm approx (HxLxW) : 700x1000x150 - (470 with the base)
• Weight approx. kg 25
• Input power supply: AC 220V±10% 50 Hz
• Working temperature: -40℃ ~ +50℃.
The system covers the following subjects:
• Heavy vehicle wiring diagrams
• Heavy vehicle Electronics Control Module (ECM)
• Heavy vehicle electronic fuel injection systems
• Heavy vehicle sensors
• Heavy vehicle exhaust gas analysis and emission control
• Heavy vehicle turbochargers and blowers
• Heavy vehicle cold start systems
• 12 V circuits
• Electronic control of vehicle performance and speed
• Engine protection
• Tamper resistance
• Fault finding
This vertical frame bench-top trainer is specially designed to show to students how automotive systems work.
The simulator consists of a panel operated by the support of a computer with a coloured silk-screen diagram that clearly shows the structure of the system and allows the location of the components on it.
The display of the information available on the computer screen allows the continuous control of the educational system.
The operational conditions can be entered by the students and the insertion of faults can be carried out through the computer by the teacher. The trainer is supplied with a CAI Software and the supported documentation guides the students to the study and the performance of the simulation exercises.
All components installed and given leads are made to protect the safety of the students.
