ABSTRACT:
A cylinder block of an automotive engine comprises a cylinder wall section defining an engine cylinder and connected to a cylinder block skirt section. A water jacket outer wall section is connected to the cylinder wall section and located separate from the skirt section at a portion integral with the cylinder wall section, so that a lower part of the cylinder wall section between the water jacket outer wall section and the skirt section is exposed to ambient air. Additionally, the lower part of the cylinder wall section is integrally formed at its outer surface with a boss section to which an engine knock sensor is secured. Accordingly, engine knock is effectively transmitted to the engine knock sensor, thereby improving the sensing accuracy of the engine knock sensor.
