Answers

Answer 1

One of the best indicators of reciprocating engine combustion chamber problems is **abnormal combustion patterns**.

The combustion chamber is where the fuel-air mixture is ignited and burned to generate power in a reciprocating engine. Any issues or abnormalities within the combustion chamber can have a significant impact on engine performance and reliability. Some common indicators of combustion chamber problems include:

1. **Misfiring**: Misfiring occurs when the fuel-air mixture fails to ignite properly or ignites at the wrong time. It can result in rough engine operation, reduced power output, and increased fuel consumption.

2. **Knocking or pinging**: Knocking or pinging sounds during engine operation indicate improper combustion, often caused by abnormal combustion processes like detonation or pre-ignition. These can lead to engine damage if not addressed promptly.

3. **Excessive exhaust smoke**: Abnormal levels of exhaust smoke, such as black smoke (indicating fuel-rich combustion), blue smoke (indicating oil burning), or white smoke (indicating coolant leakage), can indicate combustion chamber problems.

4. **Loss of power**: Combustion chamber problems, such as poor fuel atomization, inadequate air-fuel mixture, or insufficient compression, can result in a loss of engine power.

5. **Increased fuel consumption**: Inefficient combustion due to combustion chamber problems can lead to increased fuel consumption, as the engine struggles to burn the fuel-air mixture effectively.

To diagnose and address combustion chamber problems, it is essential to conduct thorough engine inspections, analyze engine performance data, and perform necessary maintenance or repairs to ensure proper combustion and optimize engine efficiency.

Partially automated scanner that reads the piece-goods vouchers costs about 1308900 to make it operational. operating costs are projected to be around 655,500 per year. the scanner is expected to last for five years. the scanners net salvage value is 130,000, according to estimates. the new automated system is estimated to save birr 1,700,500 in labour cost per year calculate - net cash flow over the life of the scanner - what is the time frame for recouping your investment - if the interest rate is 15% after taxes, what would be the discount pay back period?

Answers

To calculate the net cash flow over the life of the scanner, we need to consider the operating costs, salvage value, and labor cost savings.

Net cash flow = operating costs - salvage value + labor cost savings
Operating costs per year = 655,500
Operating costs over 5 years = 655,500 * 5 = 3,277,500
Net salvage value = 130,000
Labor cost savings per year = 1,700,500
Labor cost savings over 5 years = 1,700,500 * 5 = 8,502,500
Net cash flow = 3,277,500 - 130,000 + 8,502,500 = 11,650,000

To determine the time frame for recouping your investment, we need to calculate the payback period.

Payback period = Initial investment / Net cash flow per year
Initial investment = 1,308,900
Net cash flow per year = labor cost savings per year - operating costs per year
Net cash flow per year = 1,700,500 - 655,500 = 1,045,000
Payback period = 1,308,900 / 1,045,000 = 1.25 years
If the interest rate is 15% after taxes, the discount payback period can be calculated using the following formula:
Discount payback period = Payback period / (1 + interest rate)
Discount payback period = 1.25 / (1 + 0.15) = 1.09 years
