Calculating Automotive Engine Power: Load Capacity vs Dry Weight

In summary, the formula for calculating automotive engine power is Power = Torque x RPM / 5252. Load capacity refers to the maximum weight that a vehicle can safely carry, and it is directly related to engine power. Dry weight, which is the weight of a vehicle without any fluids or additional cargo, is an important factor in determining engine power as a lighter vehicle will require less power to move and accelerate. Increasing engine power alone will not increase the load capacity of a vehicle, as other factors such as structural integrity and suspension system also play a role. A larger engine can increase the load capacity of a vehicle due to its increased power and torque, but it can also decrease the load capacity if it exceeds the vehicle's maximum weight limit.

Hi veryone this is my first post...
i am given with 2 datas-they r load capacity=250 kg; Dry wt of vehicle=150kg...I have a doubt...when we r calculating the power of an automotive engine, which wt. shud be taken for calculation...or should we takje the sum of them?:confused:

Well if the vehicle is laden, take the weight of everything there. If your lorry is full of bricks, they'll have an effect on its performance.

How are you using weight to calculate power?

I can provide some insight into this question. When calculating the power of an automotive engine, the weight that should be taken into consideration is the total weight of the vehicle, including the load capacity and the dry weight. This is because the engine needs to provide enough power to move the entire weight of the vehicle, including any additional weight from passengers or cargo.

In some cases, the load capacity may be exceeded, which would require the engine to work harder and potentially affect its performance. In these cases, it may be necessary to calculate the power based on the total weight of the vehicle and the load, rather than just the dry weight.

Additionally, it is important to consider other factors such as aerodynamics, terrain, and driving conditions when calculating engine power. These can all impact the performance of the engine and should be taken into account when determining the appropriate power for a vehicle.

In summary, when calculating the power of an automotive engine, it is best to take into consideration the total weight of the vehicle and any additional load, rather than just the dry weight. This will provide a more accurate representation of the engine's capabilities and ensure optimal performance.
 

Related to Calculating Automotive Engine Power: Load Capacity vs Dry Weight

1. What is the formula for calculating automotive engine power?

The formula for calculating automotive engine power is: Power = Torque x RPM / 5252.

2. How is load capacity related to engine power?

Load capacity refers to the maximum weight that a vehicle can safely carry. Engine power is directly related to load capacity, as a more powerful engine can typically handle a heavier load.

3. What is dry weight and how does it affect engine power?

Dry weight refers to the weight of a vehicle without any fluids or additional cargo. It is an important factor in determining engine power, as a lighter vehicle will require less power to move and accelerate.

4. Can the load capacity of a vehicle be increased by increasing engine power?

No, increasing the engine power alone will not increase the load capacity of a vehicle. Other factors such as the structural integrity and suspension system also play a role in determining the load capacity.

5. How does engine size affect the load capacity and dry weight of a vehicle?

A larger engine typically means more power and torque, which can increase the load capacity of a vehicle. However, a larger engine also means a heavier weight, which can decrease the load capacity if it exceeds the maximum weight that the vehicle can handle.
