Heat transfer occurs through conduction, convection, and radiation.

• Conduction is the transfer of heat through a material without any movement of the material itself.

• Convection is the transfer of heat through the movement of fluids or gases.

• Radiation is the transfer of heat through electromagnetic waves.

• Examples include touching a hot stove (conduction), boiling water (convection), and feeling the warmth of the sun (rad

Reduce risk of global warming from R12 in air-conditioners

A diesel generator works by converting diesel fuel into mechanical energy which is then converted into electrical energy.

• Diesel fuel is injected into the combustion chamber where it ignites and creates high pressure gases that push the piston down, creating mechanical energy.

• The mechanical energy is then converted into electrical energy through the use of an alternator.

• The alternator uses a magnetic field and a conduct...read more

A diesel engine works by compressing air in the cylinder, which heats up and ignites the fuel injected into the cylinder.

• Air is drawn into the cylinder and compressed by the piston

• The compressed air heats up and ignites the fuel injected into the cylinder

• The explosion pushes the piston down, which turns the crankshaft and powers the engine

• Diesel engines are more efficient than gasoline engines because they compress the...read more

A train doesn't need a differential because its wheels are fixed to the same axle and rotate at the same speed.

• Train wheels are fixed to the same axle

• Wheels rotate at the same speed

• Differential is used in vehicles with wheels that rotate at different speeds

• Differential allows for smooth turning

Petrol engines have lower compression ratios compared to diesel engines.

• Petrol engines have lower compression ratios to prevent knocking or detonation.

• Diesel engines have higher compression ratios to ignite the fuel without spark plugs.

• Higher compression ratios in diesel engines result in better fuel efficiency and torque.

• Petrol engines require lower compression ratios to accommodate the lower octane rating of petrol f...read more

A turbocharger is a device that increases the power output of an engine by compressing air. BS 6 is a set of emission standards for vehicles.

• A turbocharger uses exhaust gases to spin a turbine, which compresses air and sends it to the engine

• This compressed air allows the engine to burn more fuel and produce more power

• BS 6 is a set of emission standards that require vehicles to emit fewer pollutants than previous standa...read more
