Sparkle lighting solutions Interview Questions and Answers

Turbocharger uses exhaust gases to compress air and increase engine power. Compressor map shows its efficiency.

• Turbocharger uses a turbine to spin a compressor wheel

• Exhaust gases from the engine turn the turbine

• The compressor wheel draws in air and compresses it

• Compressor map shows the efficiency of the turbocharger at different operating conditions

• Efficiency is measured by pressure ratio and mass flow rate

NOx formation is a result of high combustion temperatures in diesel engines. EGR reduces NOx by recirculating exhaust gases.

• NOx is formed due to high combustion temperatures

• EGR reduces NOx by recirculating exhaust gases

• EGR dynamics involve controlling the amount of exhaust gas recirculated

• EGR can affect engine performance and emissions

• NOx formation can be reduced by using SCR (Selective Catalytic Reduction) systems

I have extensive experience in Matlab, Python, and R.

• I have used Matlab for data analysis and modeling in my previous job at XYZ company.

• I have developed machine learning algorithms using Python for a project at ABC company.

• I have used R for statistical analysis and visualization in my graduate research.

• I am proficient in all three languages and can easily switch between them depending on the project requirements.

The trapping rain water problem involves calculating the amount of water that can be trapped between bars in an array.

• Use two pointer approach to keep track of the left and right boundaries.

• Calculate the amount of water that can be trapped at each bar by finding the minimum height of bars on the left and right sides.

• Sum up the trapped water at each bar to get the total amount of water trapped.

• Example: Input array [0,1,0,2,1,0,1,3,2,1,2,1] would trap 6 units of water.
