Table 1 Engine Specifications  Cylinder Bore  82.55 mm  Stroke 114.3  mm  Displacement 611.7  cc  Connecting Rod  Length  254 mm  Compression Ratio  4.6~16  Combustion Chamber  Pancake shape  Intake valve open
Figure 2 Variation of effective intake mixture temperature  with intake air temperature
Table 2 Repeatability of HCCI engine operation*
Fig. 5 shows the effect of engine speed on HCCI  combustion. Increasing engine speed tends to reduce  cylinder pressure and retard peak pressure location, due to  a significantly retarded main combustion stage as shown  in Fig
+5
