Hello, due to lack of time, I need you to write the observations and conclusions.
let me know before if you understand
Dear Professor Neal, As we conclude our engine overhaul lab on the Predator Engine 173 cc, we are pleased to present a comprehensive report detailing our procedures, challenges encountered, and recommendations for future improvements. Engine Identification: • Predator Engine 173 cc • Model Number: 69731 • Serial Number: A2307033093 Procedures Overview: 1. Preliminary Checks: Before delving into the lab, we rigorously tested the engine, running our project engine and meticulously examining the compressor reading, which stood at 78/80. This initial step ensured that we had a clear understanding of the engine's condition before proceeding further. 2. Inspection and Disassembly: Utilizing the service manual as our guide, we meticulously determined all torque values and clearances necessary for the disassembly process. Armed with this knowledge, we embarked on the careful disassembly of our engine, referring to both the engine manual and photo journal books for precision and accuracy. 3. Carburetor Inspection: With meticulous attention to detail, we disassembled the carburetor, identifying each component and addressing all questions outlined in the operation sheet. This step was crucial in ensuring that our engine's fuel delivery system was in optimal condition. 4. Engine Assembly: Following a thorough inspection and meticulous measurements, we meticulously reassembled our engine. Adhering strictly to the service manual and photo journal books, we ensured that each component was reinstalled correctly, leaving no room for error. 5. Ignition System Inspection: Delving into the intricacies of the ignition system, we meticulously identified all components and meticulously measured the resistance values for both primary and secondary coils. Additionally, we conducted a comprehensive inspection of the spark plug before reinstalling the entire ignition system back into the engine. Difficulties Encountered: • Throttle's Butterfly Valve Disassembly: Unfortunately, one of our team members accidentally disassembled the throttle's butterfly valve, leading to gasoline leakage. Moving forward, we must exercise utmost caution to prevent such incidents. • Limited Tools and Cramped Space: The cramped confines of the engine compartment, coupled with our limited tools, posed significant challenges during the tightening of engine screws to their appropriate torque values. We must explore alternative solutions to mitigate such issues in the future. • Difficulty in Disassembling Engine Parts: Some engine parts proved to be stubborn during the disassembly process, necessitating assistance from the instructor to complete the task. This highlights the importance of seeking guidance and collaboration when faced with obstacles beyond our expertise. Recommendations: • Enhanced Training: Consideration should be given to providing additional training sessions or workshops focusing on the proper handling and disassembly of engine components to prevent accidental damage. • Tool Inventory Assessment: Conduct a thorough assessment of our tool inventory to identify any deficiencies and acquire necessary tools to facilitate smoother operations in future labs. • Space Optimization: Explore opportunities to optimize the layout of our workspace to alleviate the constraints posed by the cramped engine compartment, thereby enhancing efficiency and productivity. 2. Introduction In the Engine Overhaul Lab, we as a student engage in hands-on exploration of engine maintenance and repair, focusing on the Predator Engine 173 cc, Model Number: 69731. This lab provides a practical avenue for students to apply theoretical knowledge, refine diagnostic skills, and master precision procedures essential for engine overhaul. Comprising five procedures: preliminary checks, Inspection and Disassembly, Carburetor Inspection, Engine Assembly, and ignition system inspection, we navigate real-world challenges typical of engine repair environments. Disassembly, re-assembly, and research into manufacturer manuals prompt us to refine techniques, exercise caution, and collaborate effectively. Through collaboration and problem-solving, we bridge theory with practice, cultivating essential skills in engine diagnostics and repair. This lab report documents our journey of exploration and discovery in the realm of automotive engineering. Here’s the note for Observations part: 1/ Carburetor leaking because the float needle is not close all the way (we fixed that by adjusting the spring) 2/ Valve’s clearance is too big. supposed to be 0.004 in (we fixed that by re-adjusting the clearance) 3/ Carburetor’s butterfly valve shut all the way (supposed to be a gap between the choke plate and the carburetor) (we fixed that by tightening the black bolt on the side of the carburetor to adjust butterfly valve)
