Honda Motorcycle & Scooter Diploma Trainee Interview Questions and Answers

Addendum and dedendum are terms used in gear design to describe specific parts of a gear tooth.

• Addendum is the distance between the pitch circle and the top of the gear tooth.

• Dedendum is the distance between the pitch circle and the bottom of the gear tooth.

• Addendum and dedendum are important in determining the strength and durability of gears.

• For gears to mesh properly, the addendum of one gear must align with the ded...read more

DTSi technology is a patented technology used in Bajaj motorcycles for better fuel efficiency and performance.

• DTSi stands for Digital Twin Spark Ignition

• It uses two spark plugs to ignite the fuel mixture in the combustion chamber

• This results in better combustion and fuel efficiency

• It also leads to smoother engine operation and reduced emissions

• Bajaj Pulsar is a popular motorcycle model that uses DTSi technology

2 stroke engines have a power stroke in each revolution, while 4 stroke engines have a power stroke in every other revolution.

• 2 stroke engines have a simpler design and are lighter than 4 stroke engines.

• 2 stroke engines have a higher power-to-weight ratio compared to 4 stroke engines.

• 4 stroke engines are more fuel-efficient and produce less pollution than 2 stroke engines.

• Examples of 2 stroke engines include chainsaws,...read more

Compression ratio for diesel is higher than petrol due to their different combustion characteristics.

• Compression ratio is the ratio of the volume of the combustion chamber from its largest capacity to its smallest capacity.

• Diesel engines have a higher compression ratio than petrol engines due to their different combustion characteristics.

• The compression ratio for diesel engines typically ranges from 15:1 to 20:1, while...read more

Explanation of Carnot and Diesel cycles through diagrams and examples

• Carnot cycle is a theoretical cycle that involves four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression

• Diesel cycle is a practical cycle used in diesel engines that involves four processes: adiabatic compression, constant pressure heat addition, adiabatic expansion, and constant volume ...read more

The ratio of fuel and air mixture in combustion engine is called air-fuel ratio.

• Air-fuel ratio is the amount of air mixed with fuel in the combustion chamber of an engine.

• The ideal air-fuel ratio for gasoline engines is 14.7:1.

• The air-fuel ratio can be adjusted to optimize engine performance and fuel efficiency.

• A rich air-fuel ratio (more fuel, less air) can cause poor fuel economy and increased emissions.

• A lean air-fu...read more
