For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine at 600 rpm with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane. [8]
The Toyota Dynamic Force engine is a family of internal combustion engines developed by Toyota under its Toyota New Global Architecture (TNGA) strategy. These I3 , I4 and V6 engines can be operated with petrol (gasoline) or ethanol ( flex-fuel ) and can be combined with electric motors in a hybrid drivetrain.
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
The net result is that the engine has a greater effective expansion than compression. Output is 73 kW (98 hp; 99 PS) at 5200 rpm and 142 N⋅m (105 lb⋅ft) of torque at 4000 rpm, paired with electric motor/generators in the hybrid drive system; together the engine and electric motors produce up to 103 kW (138 hp; 140 PS) and 207 N⋅m (153 lb ...
A higher mechanical compression ratio, or dynamic compression ratio with forced induction, can be used to improve thermodynamic efficiency.Because fuel is not injected into the combustion chamber until just before the combustion is required to begin, there is little risk of pre-ignition or engine knock.
Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor.It shows changes in fluid pressure, temperature, entropy, flow rate etc.) with the compressor operating at different speeds.
