The engine concept, which was invented past times Gerhard Schmitz, has been developed past times Ilmor into a working engine using a rapid image cast cylinder head, a machined from enterprise cylinder block together with course electrically powered fossil oil together with H2O pumps. Two overhead camshafts operate the conventional curl boundary valvegear amongst the HP camshaft running at 0.5 x crank speed together with the LP camshaft running at i x crank speed. The engine is equally good turbocharged to growth 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 move to move extracted, thence increasing thermodynamic efficiency.
• The engine runs an overall expansion ratio approaching that of a diesel fuel engine – inwards the share of 14.5:1
• Minimised pumping move due to the downsizing trial from highly rated firing cylinders.
• The compression ratio tin john move reduced to delay knock onrush without a reduction inwards performance.
• Because the firing cylinders tin john move real highly rated, the engine is relatively compact.
• The fuel consumption does non ascension equally chop-chop amongst increasing BMEP, equally retarding rejects to a greater extent than unloosen energy into the expansion cylinder.
• The engine uses 100% conventional applied scientific discipline together with 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 wheel which alternately exhaust into a key expansion cylinder (Low Pressure - LP), whereupon the burnt gases perform farther work. The LP cylinder decouples the expansion together with compression processes together with enables the optimum expansion ratio to move 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 onrush of knock a greater per centum of move tin john move extracted inwards the LP cylinder, giving a score of self compensation.
