Brake output per displacement is defined as the brake power obtained per single displacement of piston from TDC to BDC or vice versa. It's a measure of engine efficiency in converting displacement into useful work output.
The calculator uses the formula:
Where:
Explanation: This formula calculates how much brake power is generated per unit of piston displacement, indicating the engine's volumetric efficiency and power density.
Details: Calculating brake output per displacement helps engineers evaluate engine performance, compare different engine designs, and optimize combustion efficiency for maximum power output relative to engine size.
Tips: Enter brake power per cylinder per stroke in watts and displaced volume in cubic meters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is brake power per cylinder per stroke?
A: It's the amount of useful power output from a single cylinder during one complete stroke cycle of the piston.
Q2: How is displaced volume measured?
A: Displaced volume is calculated as the cross-sectional area of the cylinder multiplied by the stroke length of the piston.
Q3: What are typical values for brake output per displacement?
A: Values vary significantly by engine type and design, but higher values generally indicate more efficient engines that produce more power per unit of displacement.
Q4: How does this relate to engine efficiency?
A: Higher brake output per displacement typically indicates better volumetric efficiency and more complete combustion within the engine cylinder.
Q5: Can this calculation be used for different engine types?
A: Yes, this calculation applies to various internal combustion engines including gasoline, diesel, and other piston-driven engines.
