Maximum temperature produced in an I.C engine cylinder ranges from 2000-2500°C

The maximum temperature produced in an internal combustion (I.C) engine cylinder is determined by various factors such as the type of fuel used, the compression ratio of the engine, and the efficiency of the combustion process.

Factors influencing the maximum temperature:
1. Type of fuel: The energy content and combustion characteristics of the fuel used in the engine play a significant role in determining the maximum temperature. Fuels with higher energy content and better combustion properties tend to produce higher temperatures.

2. Compression ratio: The compression ratio of an engine is the ratio of the cylinder's volume at the bottom dead center (BDC) to the volume at the top dead center (TDC). A higher compression ratio leads to higher temperatures in the cylinder due to increased pressure and compression of the air-fuel mixture.

3. Efficiency of combustion: The efficiency of the combustion process also affects the temperature in the cylinder. Incomplete combustion can result in lower temperatures, while efficient combustion leads to higher temperatures.

Reason for option 'C' being the correct answer:
Option 'C' states that the maximum temperature produced in an I.C engine cylinder ranges from 2000-2500°C. This range is a reasonable estimate based on the typical operating conditions and design parameters of modern internal combustion engines.

Additional information:
It is important to note that the maximum temperature mentioned refers to the peak temperature during the combustion process and not the average temperature throughout the entire engine cycle. The temperature in the cylinder can vary at different stages of the engine cycle, with the peak temperature occurring during the combustion stroke.

Furthermore, it is crucial to control the temperature within the engine to prevent overheating and potential damage. Engine cooling systems, lubrication, and other measures are employed to manage the temperature and ensure optimal engine performance and longevity.
