Dreams Technologies Interview Questions and Answers

Torque flattens after a certain RPM due to engine limitations and efficiency factors.

• At higher RPMs, engine components experience increased friction and heat, leading to reduced torque output.

• Engine design, intake/exhaust flow, and fuel delivery systems can also limit torque output at higher RPMs.

• Peak torque is typically achieved at a specific RPM range, beyond which the torque curve flattens out.

• Efficiency considerations may also play a role in limiting torque output at high...read more

Power keeps rising even if torque flattens out due to the relationship between the two variables.

• Power is the rate at which work is done or energy is transferred, calculated as the product of torque and angular velocity.

• Even if torque flattens out, the power can continue to rise if the angular velocity increases.

• This is because power is a function of both torque and angular velocity, so an increase in one can compensate for a decrease in the other.

Traction control is a system that helps prevent wheel spin during acceleration, while an end is the point where a vehicle's acceleration is limited due to loss of traction.

• Traction control helps maintain traction by reducing engine power or applying brakes to individual wheels

• An end occurs when traction control is unable to prevent wheel spin, causing acceleration to be limited

• Traction control is commonly found in modern vehicles to improve stability and control in slippery c...read more

By assessing the vehicle's condition, cost of repairs, safety concerns, and market value.

• Evaluate the overall condition of the vehicle including mileage, age, and wear and tear.

• Calculate the cost of necessary repairs and compare it to the vehicle's market value.

• Consider safety concerns such as structural damage or mechanical issues.

• Assess the vehicle's potential for refurbishment and resale value.

• Consult with experts or mechanics for professional opinion.

• Example: A vehicle wi...read more

Turbo improves the efficiency of an engine by increasing the amount of air and fuel mixture that can be compressed and burned, resulting in more power output.

• Turbochargers increase the power output of an engine without increasing its size or weight.

• Turbochargers improve fuel efficiency by allowing smaller engines to produce the same power as larger engines.

• Turbochargers reduce turbo lag, providing instant power when needed.

• Turbochargers can improve overall engine performance ...read more
