Estimating the term…
A number of embodiments of V-type engine particularly adapted for transverse disposition in an engine compartment either at the front or rear of the vehicle. By appropriately staggering the cylinder banks and locating the various accessory drives, it is possible to make the engine more compact than previous engines and thus permits the use of V-type engines of more than 6 cylinders in such engine compartment placement. In addition, the induction system is designed in such a way so as to not only maintain a compact configuration, but also to reduce the number of plenum chambers that are employed and to permit a single plenum chamber that is disposed over the passenger compartment cylinder bank where the hood line is normally the highest. Thus, low hood lines can be maintained.
A motor vehicle having an engine compartment at one end of said vehicle and on one side of a passengers' area of said vehicle, said vehicle having a pair of transversely spaced, longitudinally extending frame members at a lower area of said engine compartment, a V-type internal combustion engine positioned in said engine compartment with a crankshaft journalled for rotation about an axis that extends transversely to the length of said vehicle, said engine having a pair of angularly disposed cylinder banks defining a valley therebetween, each of said cylinder banks defining a plurality of cylinder bores, a transmission driven by said engine at one end thereof for driving at least a pair of wheels of said vehicle, the cylinder bores of said cylinder banks being staggered, at least one overhead cam shaft journalled in each of said cylinder banks for actuating valves located therein, and an accessory drive for driving an engine accessory from the transmission end of the cam shaft of one of said cylinder banks.
A motor vehicle as set forth in claim 3 wherein there are a pair of overhead camshafts journalled in each cylinder bank.
A motor vehicle as set forth in claim 41 wherein the inlet pipe enters the plenum chamber between the center pair of manifold runners
A motor vehicle having an engine compartment at one end of said vehicle and on one side of a passengers' area of said vehicle, said vehicle having a pair of transversely spaced, longitudinally extending frame members at a lower area of said engine compartment, a V-type internal combustion engine positioned in said engine compartment with a crankshaft journalled for rotation about an axis that extends transversely to the length of said vehicle, said engine having a pair of angularly disposed cylinder banks defining a valley therebetween, each of said cylinder banks defining a plurality of cylinder bores, a transmission driven by said engine at one end thereof for driving at least a pair of wheels of said vehicle, the cylinder bores of said cylinder banks being staggered, each of said cylinder banks having a plurality of intake ports disposed contiguous to said valley, a plenum chamber disposed over the cylinder bank closest to said passengers' area, a plurality of manifold runners extending from said plenum chamber to said intake ports, an air inlet and an inlet pipe extending from said air inlet to said plenum chamber.
A motor vehicle having an engine compartment at one end of said vehicle and on one side of a passengers' area of said vehicle, said vehicle having a pair of transversely spaced, longitudinally extending frame members at a lower area of said engine compartment, a V-type internal combustion engine positioned in said engine compartment with a crankshaft journalled for rotation about an axis that extends transversely to the length of said vehicle, said engine having a pair of angularly disposed cylinder banks defining a valley therebetween, each of said cylinder banks defining a plurality of cylinder bores, a transmission driven by said engine at one end thereof for driving at least a pair of wheels of said vehicle, the cylinder bores of said cylinder banks being staggered and each of said cylinder banks having a plurality of intake ports disposed contiguous to said valley, said intake ports all having inlet openings lying in a line.
