MRC Benchmarks
Our approach to innovation and business
As an engineering firm, MRC coordinates all activities around actual technology benchmarks; not marketing campaigns or computer generated models of theoretical engines. Such an approach by necessity is dominated by relentless prototyping- a process that is as challenging as it is expensive. But in the field of green engine technology, there are no shortcuts, and the revolutionary technology our company has produced is a testament to our commitment to getting the science right.
How we measure milestones
Internal Combustion (IC) engines operate in many sectors of the global economy, from powering ships to trains, trucks, cranes, cars and even Power Stations. All of these IC engines are designed to be application specific. Notwithstanding this, there are a number of key indicators that can be used to compare all these engines in terms of their efficiency; and in the process, identify which designs will dominate the global economy in years to come. The difference between many applications is a question of scale, not core design.
Key Indicators:
- Torque per Liter displacement ratio
- Brake Mean Effective Pressure
- Power-to-weight ratio
- Thermal Efficiency and BSFC
Torque per Liter displacement ratio:
This calculation is at the heart of measuring an engines mechanical efficiencies. Torque is the twisting power and the displacement is volume swept by the piston inside the cylinder. In effect, the more power you produce per liter of displacement, the more mechanically efficient your engine design.
Brake Mean Effective Pressure (BMEP):
This calculation represents a genuine comparison of engine designs regardless of actual size of each engine. In other words, engines with completely different characteristics such as size, speed (rpm) and so forth, but equal efficiencies, will have equal values of BMEP.
Power-to-weight ratio:
This calculation is applied to engines (including internal combustion engines) to enable the comparison of one design to another. For an accurate comparison, it is necessary to break the power component down again to both horsepower and peak torque. This distinction is necessary as many industrial applications (including heavy duty transport) revolve around an engine’s peak torque whilst smaller transport vehicles or small generators may favor horsepower as a reliable performance indicator.
Thermal Efficiency:
This calculation is used to compare engines (both turbine and internal combustion) in terms of an engine’s efficiency in converting chemical energy (contained in the fuel) into mechanical work. One way this efficiency is often expressed is by calculating an engine’s BSFC (Brake Specific Fuel Consumption).
MRC performance:
At MRC, we use all of these indicators to assess the performance of our technology. In reality however, the market place simply wants to know just how much torque an engine can produce given its cylinder displacement. At the end of each year we test ourselves on this scale and compare ourselves to other market participants.
In December 2011, we will release the performance of our engines for this year. Below you can review charts that detail MRC’s progress since 2009.
