(COMPETENCY-BASED QUESTIONS)

Answer any 02 questions out of the given 03 questions

Q.19 The main requirements of a good clutch are:

1. Torque transmission: The clutch should be able to transmit maximum torque of the engine.
2. Gradual engagement: The clutch should engage slowly to avoid sudden jerks.
3. Heat dissipation: The clutch should be able to dissipate large amount of heat generated due to friction.
4. Dynamic balancing: The clutch should be dynamically balanced.
5. Vibration damping: The clutch should have suitable mechanism to damp vibrations to eliminate noise produced during the power transmission.
6. Size: The clutch size should be as small as possible so that it will occupy minimum space.
7. Free pedal play: The clutch should have free pedal play in order to reduce effective load on the carbon thrust bearing and its wear.
8. Easy in operation: The clutch should be easy to operate.
9. Lightness: The driven member of the clutch should be made as light as possible.

Q.20 Safety and Security Systems of Modern Vehicles:

There are different safety and security systems are available in the market and some of which are fitted by the manufacturer. Following are the few active and passive security systems.

(Answer any 4 of the following)

1. Safety Glass: The safety glass employed in modern vehicles are laminated or tempered. These types are said to be safety glass because of their construction.

Laminated plate glass is used to make all windshields. This type of glass consists of two thin sheets of glass with a thin layer of clear plastic between them. When this type of glass is broken, the plastic material will tend to hold the shattered glass in place and prevent it from causing injury.

2. Seat Belt: Sometimes it is also called as safety belt. It is designed to secure the occupants of a vehicle against harmful movement that may result during a collision or a sudden stop. In modern cars seat belts are also provided for rear seat occupants also.
3. Airbags: It is a vehicle safety device. This is one of the passive safety systems for the occupants of car. The electrical system of air bags includes the impact sensors and the electronic control module. When there is an accident the sensor detects the impact and the air bag operates to save the driver and other occupants.
4. Energy-Absorber Safety Bumpers: Modern vehicle bumpers are designed to absorb the energy of a low-speed impact, minimizing the shock directed to the frame and to the occupants of the vehicle. Most energy absorbers are mounted between the bumper face bar or bumper reinforcement bar and the frame.
5. Security and Antitheft Devices: There are three basic types of antitheft devices available: locking devices, disabling devices, and alarm systems.

Q.21 Automobile Pollution and Its Control:

Automobiles are said to be one of the major causes for atmospheric pollution at least in the metro cities.

Main causes of automotive pollution:

Poorly design and poorly maintained automobiles: You must have seen on roads a bus or truck or car or tempo releasing black smoke. This is because of poor maintenance of the vehicle.

Incomplete burning of fuel air mixture: Poorly maintained vehicle’s engine does not burn the fuel completely or properly. It can also happen because of improper mixture of air and fuel.

Adulterated or poor quality of fuel: Petrol or diesel mixed with non-standard liquids/ substances increase the pollution.

Excess use of clutch while driving: The habit of riding on clutch while driving increase the fuel consumption and increase the pollution.

Its Control:

Proper maintenance of automobiles along with use of lead-free petrol or diesel can reduce the pollutants they emit.

Catalytic converters, having expensive metals namely platinum-palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases.

As the exhaust passes through the catalytic converter, unburnt hydrocarbons are converted into carbon dioxide and water. Also, carbon monoxide and nitric oxide are changed to carbon dioxide and nitrogen gas, respectively. Motor vehicles equipped with catalytic converter should use unleaded petrol because lead in the petrol reduces effectiveness of the catalyst.

Good driving habits: It reduces the pollution by reducing the fuel consumption.
