Research on the History and developments on Internal Combustion Engines.
Step by step
Solved in 3 steps
- Why renewable energy sources are called sustainable? List out any two reasons why they are considered environment friendly?Internal combustion engine I hope for a solution and as soon as possible, with thanks and appreciationSpecific fuel consumption of a four-stroke internal combustion engine at a given rotational speed is 0.322 kg/kW-h value is minimum. Spindle power at this rotation rate is 123 kW, volumetric efficiency is 95% and air-fuel rate is 15. The number of rotations of this engine is calculated by subtracting 1.5 from the number of rotations giving the minimum specific fuel consumption. time, spindle power 162 kW, specific fuel consumption 0.394 kg/kW-h and volumetric efficiency 85%. a) Calculate the air-fuel ratio in this case. and By what percent has the efficiency of the engine changed?
- Either for gas turbines OR for internal combustion engines, for the sustainable renewable energy future of Mauritius, explain which fuel(s) can be used and explain the combustion process with the help of relevant equations and diagrams. Show clearly how sustainability is achieved through the proper thermal engineering processes. Only few information provided in the images.This is a question from Sustainable Energy 2nd Edition by Richard Dunlap: If a high head hydroelectric facility is considered to be carbon free, what is the annual reduction in CO2 emissions for a 1000 MWe hydroelectric station compared to a 1000 MWe coal-fired station operating at 38% efficiency? Assume both stations have a 70% capacity factor.Describe the features, components, electric propulsion systems, and workingprinciples of electric and hybrid vehicles.
