Abstract
An internal combustion engine includes a throttle valve assembly having a main passage and an idle air passage. The main passage is in fluid communication with the intake valve, air being intermittently input into a combustion space through the main passage based on position of an intake valve. The idle air passage is integrally formed in the throttle valve body, and is controlled by a motor to selectively introduce air into the main passage downstream of the throttle plate. For a cylinder hole diameter in the range from 70 mm to 74 mm, both the intake valve angle defined between the intake valve axis and the cylinder axis and the exhaust valve angle defined between the exhaust valve axis and the cylinder axis are in the range from 11 degrees to 15 degrees.
