Title:
V-6 DOUBLE OVERHEAD CAMSHAFT INTERNAL-COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS61145306
Kind Code:
A
Abstract:
PURPOSE:To standardize parts by arranging two camshafts of similar construction to form both righthand and lefthand bank camshafts while those camshafts being mutually reversed to each other in axial direction. CONSTITUTION:The righthand bank cylinder head 2 has an air intake camshaft 3 and exhaust camshaft 6 of similar construction as their counterparts 3 and 5 in the lefthand bank cylinder head 1, with their shaft being arranged in mutually reversed directions. The air intake camshaft 3 is interlocked with the exhaust camshaft 5 through gears 25 and 26 in the leftside bank while the air intake camshaft 4 with the exhaust camshaft 6 through gears 27 and 28. The camshafts in each bank are driven by the internal combustion engine through a gear 17, 18 provided on either air intake or exhaust camshaft. Thus, camshafts for both banks can be standardized and correct firing order at an equal interval can be obtained by selecting proper number of teeth on the basis of phase difference in the meshed pair of gears 25, 26 or 27, 28 for the camshafts in each bank.
