Emissions Control

Autotronics » Emissions Control

Vehicle emissions control is the study of reducing the motor vehicle emissions produced especially in internal combustion engines. Emissions of many air pollutants have been shown to have variety of negative effects on public health and the natural environment. The principal pollutants include hydrocarbons (HC), carbon monoxide (CO), oxides from nitrogen NOX (NO + NO2), sulfur oxide (SOX) and volatile organic compounds (VOCs) that are subsection of hydrocarbons. In an ideal of 100% efficient internal combustion engine, the fuel would burn to give just carbon dioxide and water vapor. In practice, engines are far from efficient and the combustion process produces the above pollutants as well as carbon dioxide and water vapor. In recent years, public concern about atmospheric pollution and imminent pollution-control laws, has fed to car manufacturers to find ways of reducing the level of these gases in car exhausts. The two basic approaches are to use lean-burn engines or attaching catalytic converters to the exhaust system. The latter approach is the older of the two systems. The first approach is to produce a leaner mixture, namely to reduce the proportion of fuel in the fuel/air mixture entering the engine. For this category, De Lorenzo has designed two simulators that deal with the study of the techniques used for the reduction of the noxious emissions in the vehicle and of the devices and/or the systems used for controlling and reducing the emissions of gasoline engines. One of them is provided with an electric motor simulating a real engine, with phonic wheel and magnetic sensor for position and rotation speed. A fault simulator, for troubleshooting, is provided in both simulators and they can be interfaced to personal computer through a CAI software. They are recommended for professional institutes, vocational schools and technical colleges.

EMISSION CONTROL

LEARNING EXPERIENCE
The combustion of the fuel inside the cylinders of an engine is, usually, incomplete.
The more it is incomplete, the bigger is the emission of noxious components which can be found in the exhaust gases from the engine.
To reduce environmental pollution it is necessary to improve the efficiency of the engine for what concerns the exhaust gases.
This simulation panel deals with the study the techniques used for the reduction of the noxious emissions in the car.
GENERAL CHARACTERISTICS
• 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℃.
MAIN CHARACTERISTICS
It is possible to simulate:
• Composition and control of the exhaust gases in the Otto cycle based engines
• Combustion products
• Preparation and control of the fuel and operating conditions
• Adaptation to the operating conditions
• Lambda regulation
• Recirculation of the exhaust gases
• Anti-evaporation of the fuel
• Catalytic thermal post-combustion
• Analysis of the exhaust gases in the Otto cycle based engines: test cycles
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.

EMISSION CONTROL MINICAR

LEARNING EXPERIENCE
This simulation panel deals with studies the devices and the systems used for controlling and reducing the emissions of gasoline engines.
In fact, the combustion of the fuel inside the cylinders of an engine is incomplete.
The more it is incomplete, the higher the emission of noxious components that are present in the exhaust gas of the engine.
The trainer is provided with an electric motor, with phonic wheel and magnetic sensor for position and rotation speed.
The electric motor 'simulates' the operation of the real engine (all the operations are made at a speed 10 times lower than the real one of the engine: between 80 and 600 rpm).
This allows visualizing on LED the operation of the different devices: spark plugs, injectors, etc. On the LCD display the actual speeds are visualized (rpm from 800 to 6000).
All the signals (on LED and terminals) are synchronized with the rotation of the phonic wheel and this makes 'real' the operation of the trainer.
