Describe with the aid of diagrams the operational sequence of four stroke spark ignition and four stroke compression ignition engines. STEP 2 Explain and compare the mechanical efficiency of two and four-stroke engines. STEP 3 Review the efficiency of ideal heat engines operating on the Otto and Diesel cycles by explaining and generating plot(s) for thermal efficiency, ? vs compression ratio, and cut-off ratio.
You are an engineer in a company that manufactures and designs several
Task 1:
Your first customer asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report which includes the following steps:
STEP 1
Describe with the aid of diagrams the operational sequence of four stroke spark ignition and four stroke compression ignition engines.
STEP 2
Explain and compare the mechanical efficiency of two and four-stroke engines.
STEP 3
Review the efficiency of ideal heat engines operating on the Otto and Diesel cycles by explaining and generating plot(s) for thermal efficiency, ? vs compression ratio, and cut-off ratio.
STEP 4
Evaluate the performance of a two-stroke, eight-cylinder ideal Diesel cycle with a cylinder bore of 10 cm and a piston stroke of 12 cm when it is operated at 2200 rpm and the air temperature at the beginning of the compression process is 40 °C if the minimum volume enclosed in the cylinder is 5 percent of the maximum cylinder volume and the cut-off ratio is 1.7 by determining the delivered power from the engine and it’s efficiency and comparing your answer if the engine is changed to be the two-stroke engine.
