The engine concept, which was invented past times Gerhard Schmitz, has been developed past times Ilmor into a working engine using a rapid paradigm cast cylinder head, a machined from company cylinder block in addition to form electrically powered crude in addition to H2O pumps. Two overhead camshafts operate the conventional wrap jump valvegear alongside the HP camshaft running at 0.5 x crank speed in addition to the LP camshaft running at one x crank speed. The engine is equally good turbocharged to increase the engine rating.

5-stroke performance figures

• Engine capacity 700cc (turbocharged)
• Peak ability 130 bhp @ 7000 rpm
• Peak torque 166 Nm @ 5000 rpm
• Fuel consumption of solely 226 g/kWh

Advantages of the 5-stroke concept

• Influenza A virus subtype H5N1 secondary cylinder provides an additional expansion procedure enabling extra operate to endure extracted, therefore increasing thermodynamic efficiency.
• The engine runs an overall expansion ratio approaching that of a diesel fuel engine – inward the portion of 14.5:1
• Minimised pumping operate due to the downsizing number from highly rated firing cylinders.
• The compression ratio tin lavatory endure reduced to delay knock onslaught without a reduction inward performance.
• Because the firing cylinders tin lavatory endure real highly rated, the engine is relatively compact.
• The fuel consumption does non rising equally apace alongside increasing BMEP, equally retarding rejects to a greater extent than loose energy into the expansion cylinder.
• The engine uses 100% conventional applied scientific discipline in addition to and so requires no novel manufacturing techniques.

Principle of operation

The 5-stroke concept engine utilises ii fired cylinders (High Pressure - HP) operating on a conventional 4-stroke bicycle which alternately exhaust into a key expansion cylinder (Low Pressure - LP), whereupon the burnt gases perform farther work. The LP cylinder decouples the expansion in addition to compression processes in addition to enables the optimum expansion ratio to endure selected independently of the compression ratio.
Running of the concept engine has produced impressive fuel consumption readings over a real broad operating range. This is because at the onslaught of knock a greater percent of operate tin lavatory endure extracted inward the LP cylinder, giving a marking of self compensation.
