Cutaway models are an excellent educational tool for many subjects, showing the inner workings of a machine and the fine artisanship that would otherwise be hidden in an outer casing. They allow full access to all those components and give people a very revealing insight into the technology, the composition of the materials, the craftsmanship and the engineering expertise of its time. They are based on original components of the vehicle, painted normally with different colors to better differentiate the various parts and cross-sections and they are no hazards from fluids, hot surfaces and rotating parts. The educational purposes of the cutaway model are for demonstration of the different components of the engine, demonstration and explanation of the technical literature, schemes and procedures. They are normally manufactured to the highest safety standards. For this specific category, De Lorenzo provides a cutaway model of Toyota hybrid system operated manually which has two sources of power, the gasoline engine and the electric motor. It shows many specifications such as four cylinders, Double OverHead Camshaft (DOHC), Variable Valve Timing with Intelligence (VVT-I) system electronically controlled intake valves, differential group, etc. It is provided with nomenclature panel. The same trainer is available also with two electric motors (one on the petrol engine and one on the generator) and hence it can be operated electrically. They are recommended for professional institutes, vocational schools and technical colleges.
This cutaway model shows the Toyota hybrid system (THS) which has two sources of power, the petrol engine and the electric motor.
The THS recovers energy otherwise lost to heat in the brakes and uses it to supplement the power of its fuel-burning engine.
MG1 (motor generator 1) generates electrical power and starts the engine; MG2 (motor generator 2) drives the vehicle.
During deceleration, the wheels drive MG2 which acts as a generator for regenerative power recovery. The THS uses different modes to achieve the most efficient operation in response to driving conditions.
• Dim. mm approx (HxLxW) : 1300x1000x800
• Weight approx. kg 250
The cutaway model shows the following main specifications :
• 4 cylinders
• Displacement: 1500 cc
• DOHC overhead camshaft
• 4 valves per cylinder
• Roller chain
• VVT-I system (Variable Valve Timing with intelligence) electronically controlled intake valves
• Multi-point electronic injection with throttle
• Electrical engine
• Epicyclical engine
• Transmission belt (CTV)
• Differential group
• Exhaust manifold with Lambda probe
The engine is mounted on a stand with wheels and it is operated manually by means of one crank handle placed on the thermal engine and one on the electric engine in order to simulate the different cycles.
