White fumes from automobile silencer are due to condensation of water vapor and unburnt fuel.

• During combustion, water vapor is produced as a byproduct.

• When the exhaust gases cool down in the silencer, the water vapor condenses and appears as white fumes.

• Unburnt fuel can also contribute to the white fumes.

• This is a normal phenomenon and nothing to worry about unless the fumes are excessive or have a strange odor.

Exhaust gases are composed of various pollutants released from combustion of fuels.

• Exhaust gases contain carbon monoxide, nitrogen oxides, sulfur dioxide, particulate matter, and unburned hydrocarbons.

• Carbon monoxide is a poisonous gas that can cause headaches, dizziness, and even death.

• Nitrogen oxides contribute to smog and acid rain.

• Sulfur dioxide can cause respiratory problems and contribute to acid rain.

• Particulate...read more

NOx emissions can be reduced by using low NOx burners, selective catalytic reduction, exhaust gas recirculation, and fuel switching.

• Use low NOx burners in combustion processes

• Implement selective catalytic reduction to convert NOx to nitrogen and water

• Use exhaust gas recirculation to reduce oxygen levels in combustion processes

• Switch to cleaner fuels such as natural gas or hydrogen

• Optimize combustion processes to reduce

Diesel engines use compression ignition while petrol engines use spark ignition.

• Diesel engines are more fuel-efficient than petrol engines.

• Petrol engines have higher power output than diesel engines.

• Diesel engines are more durable and have longer lifespan than petrol engines.

• Petrol engines are quieter and smoother than diesel engines.

• Examples of diesel engines include those used in trucks and buses while petrol engines

The larger radius of wheels at the back of tractors provides better traction and stability.

• Larger wheels at the back increase the tractors' pulling power and ability to carry heavy loads.

• The larger surface area of the wheels distributes the weight more evenly, reducing soil compaction.

• The increased radius helps in overcoming obstacles and rough terrains.

• The larger wheels also improve the tractors' stability and prevent...read more

Disc brakes are a type of braking system used in vehicles that use a flat, circular disc to slow or stop the vehicle.

• Disc brakes work by using calipers to squeeze brake pads against a rotor attached to the wheel.

• They are more efficient than drum brakes and provide better stopping power.

• Disc brakes are commonly used in high-performance vehicles and sports cars.

• They are also used in bicycles and motorcycles.

• Disc brakes r...read more

A clutch is a mechanical device that engages and disengages power transmission between two rotating shafts.

• A clutch is used in vehicles to connect the engine to the transmission.

• It allows the driver to change gears and control the power flow.

• When the clutch pedal is pressed, the clutch disc disengages from the flywheel, interrupting power transmission.

• Releasing the clutch pedal gradually engages the clutch, allowing po...read more

A speed governor regulates the speed of an engine by controlling the fuel supply.

• Speed governor is a device that controls the speed of an engine.

• It regulates the fuel supply to the engine to maintain a constant speed.

• It works by sensing the engine speed and adjusting the fuel supply accordingly.

• There are different types of speed governors such as mechanical, hydraulic, and electronic.

• Examples of applications include ge
