Dharaksha Ecosolutions Interview Questions, Process, and Tips

Two stroke engines have a power stroke every revolution, while four stroke engines have a power stroke every two revolutions.

• Two stroke engines have a simpler design with fewer moving parts.

• Four stroke engines are more fuel efficient and produce less pollution.

• Examples: Two stroke engines are commonly used in chainsaws and motorcycles, while four stroke engines are found in cars and trucks.

SI engines use spark plugs for ignition, while CI engines use compression for ignition.

• SI engines have spark plugs to ignite the air-fuel mixture, while CI engines rely on compression to ignite the fuel.

• SI engines are commonly used in gasoline vehicles, while CI engines are typically found in diesel vehicles.

• SI engines have a higher power output compared to CI engines due to the higher compression ratio.

• SI engines are ...read more

A heat engine is a device that converts heat energy into mechanical work.

• Heat engines operate on the principle of thermodynamics.

• They typically involve a working fluid that undergoes a thermodynamic cycle.

• Examples include steam engines, internal combustion engines, and gas turbines.

Four stroke engines are generally more advantageous due to better fuel efficiency, lower emissions, and longer lifespan.

• Four stroke engines have better fuel efficiency compared to two stroke engines.

• Four stroke engines produce lower emissions, making them more environmentally friendly.

• Four stroke engines typically have a longer lifespan and require less maintenance.

• Two stroke engines are simpler in design and lighter, ...read more
