Abstract:
The design of M1 Monoblock Engine results in uniform and very intensive cooling of the entire cylinder liner area: Thermal stresses are very low. The low thermal stresses and elimination of the cylinder head bolts; helps to reduce the cylinder liner deformation to a extremely low level. The design results in a low engine weight, although the cylinder head area is cast from the grey iron. The free elongation of the cylinder head hot plate, together with the grey iron as a base material; leads to a combination of high power rating of up to 50 kW per litre displacement; free of to high thermal loading. There is no danger of cracks between the valves and the injectors and the valve seat remains round despite of two valve design per cylinder.The production costs of the Monoblock are lower than the costs for the comparable parts of classic engine design. The durability much higher.The integrated and electronically controlled high pressure fuel system with injection rate control enables very good combustion results in respect of power pollution and noise emission.
