Final answer:
Engine operating limits can be found through factors such as temperature limits and power output. These limits are usually specified in the engine's technical specifications or user manual.
Step-by-step explanation:
The engine operating limits of an automobile can be found through a combination of factors and specifications. One important factor is the temperature limits of the engine. Each engine has a specific temperature range within which it can operate efficiently and safely. These limits can be found in the engine's technical specifications or its user manual.
For example, the engine may have a maximum operating temperature of 110 degrees Celsius and a minimum operating temperature of -20 degrees Celsius. Operating the engine outside of these temperature limits can lead to overheating or poor performance.
Another factor is the engine's power output. Engines have a limit to the amount of power they can produce, which is typically measured in horsepower (hp). This limit can be found in the engine's technical specifications or provided by the manufacturer. Operating the engine beyond its power limit can lead to mechanical failures or damage.
