There are many reasons for this, but one of the most obvious is that, while the reciprocating engine has burning mixture around its spark plug for a nominal 180 degrees (the power stroke) out of 720 total degrees (or 25% of the thermodynamic cycle time), the rotary has burning mixture around its leading spark plug for roughly 70% of the cycle time.

Mathematical Modelling Comparison of a Reciprocating, a Szorenyi Rotary In the Wankel, a rounded triangle rotor spins in an eccentric orbit within an oval chamber, with each rotation producing three power strokes where the engine generates force. comments sorted by Best Top New Controversial Q&A Add a Comment . http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/carnot.html. The two rotors are used in place of the pistons. See graph:Steam Engine Efficiency. ES = Since we simplify a 13B engine to a 4 stroke piston engine -thus 2.6L- we use a coefficient of 2. t1 = Temperature of air for a known density [R], t2 = Temperature of the intake air measured by the IAT sensor [R], d1 = Density of air for a known temperature [lb/ft], [(491.67R) / (541.67R)] x (0.0808lb/ft) = d2, MF = Mass Flow rate taken from CANScan [lb/minute], AVF = Actual Volumetric Flowrate [ft/minute], [(27.3lb/minute) / (0.073341lb/ft)] = AVF, AVF = Actual Volumetric Flow rate [ft/minute], TAF = Theoretical Air Flow rate [ft/minute], [(372.233ft/minute) / (395.42ft/minute)] = AVF. For example when the tachometer on a vehicle indicates 9000rpms, one rotor is turning at 3000rpms. Due to overwhelming feedback from power equipment manufacturers calling for lighter, quieter, vibration-free engines LiquidPiston recently pivoted to the X Mini, which it developed and released in the last six months. The truth is, there isnt a lot that you can do to change the shape of the combustion depression, especially in 1989 and later engines with thin casting walls, but you can do some useful things. The Corliss engine had separate valves and headers for the inlet and exhaust steam so the hot feed steam never contacted the cooler exhaust ports and valving. The company has now received interest from potential customers, and is speaking to engine manufacturers interested in licensing the X Mini technology. This is mainly due to the fewer components within the engine. Internal-combustion engines burn one fuel-air mixture included the cylinder to move the pistons or turn the crankshaft. Its X1 engine is a simple machine with just three moving parts and thirteen major components, but it aims to raise thermal efficiency from the 20 percent of a normal gas engine to more than 50 percent, with drastic reductions in weight and size. LiquidPiston is the developer and manufacturer of a pistonless rotary engine called the X-engine, located in Bloomfield . Its principle seems straight forward: based on the calculated theoretical volumetric air flow for your engine (a Renesis in this case), and the data you logged, you can approximate the actual VE of your particular engine. The cylinder head gasket is one of the most over-engineered and stressed components in an internal combustion engine. The rotor spins around an eccentric shaft inside a housing. Using statistics collected during the early 1940s, the Santa Fe Railroad measured the efficiency of their fleet of steam locomotives in comparison with the FT units that they were just putting into service in significant numbers. Combustion is what powers most engines. STRANGE New Rotary Engine BREAKS Records - YouTube If we were to consider the rotary engine, a 4 stroke engine with a displacement of 1.3L, the results would render a VE of over 100% in more than one instance, which is very unrealistic.
