摘要： An internal combustion engine having a crankshaft, at least one camshaft, a balancer shaft and a timing drive for driving the camshaft and the balancer shaft from the crankshaft. The balancer shaft has a drive member that is interposed in the timing drive and a torsional vibration damper that is interposed between this drive member and the balancer masses on the balancer shaft to avoid transmission of crankshaft vibrations to the balancer shaft without effecting the valve timing. balancer shaft is provided that has at least offset balance masses formed thereon. The balancer shaft is also formed with integral bearings directly on opposite sides of each of the balance masses.

摘要： A vehicle and drive unit therefor including a transversely disposed engine located in an engine compartment. The engine is of the dry sump lubrication type and has a lubricant reservoir that extends between the cylinders and an air inlet opening to the engine compartment. The cylinders are inclined to the rear from a vertical plane at an acute angle and the engine crankshaft drives an output shaft that rotates in a plane disposed at an acute angle to the vertical and forwardly of the cylinder axis and at an acute angle to the cylinder axis. The oil scavenge and pressure pumps are driven from this shaft as are the front wheel axles which lie on the opposite side of the plane containing the cylinder axis from the output shaft axis.

摘要： A motor vehicle having a transversely positioned engine in a forwardly disposed engine compartment. The exhaust manifold is formed rearwardly of the engine and supplies exhaust gases to a catalyzer so that the engine will shield the exhaust manifold and catalyzer from cooling air flow. An intake manifold extends forwardly from the engine and engine accessories are disposed beneath the intake manifold and forwardly of the cylinders of the engine so as to shield the occupants of the vehicle from the noise of the accessories. In addition, a crushable plenum chamber extends across the front of the intake manifold and forwardly of the accessories for silencing and also to absorb impacts. The crushability of the plenum chamber causes it to slow the engine on impact for further safety protection.
