    摘要: A camshaft driving system for a DOHC engine having a pair of cylinder rows which are displaced from each other in the axial direction of the crankshaft so that a vacant space is formed in front of one of the cylinder rows and behind the other cylinder row. One of the camshafts in each cylinder row is provided with a timing pulley. The timing pulleys of the respective cylinder rows are arranged to be driven by the crankshaft of the engine by way of transmission means such as a chain or a timing belt passed around a crank pulley fixed to the crankshaft and the timing pulleys. The driving force transmitted to said one of the camshafts in each cylinder row is further transmitted to the other camshaft in each cylinder row by way of a driving force transmission means. The driving force transmission means in the rearwardly displaced cylinder row is disposed in the vacant space formed in front of the cylinder row and the driving force transmission means in the forwardly displaced cylinder row is disposed in the vacant space formed behind the cylinder row.

    摘要: An improved, compact auxiliary mechanism driving device in a V-type, overhead-camshaft engine in which a driving section for engine auxiliary mechanism is mounted on a camshaft without increasing the overall size of the engine by utilizing a vacant or unused space(s) on the camshafts peculiar to such an overhead-camshaft engine. A pair of first and second cylinder banks are arranged in V-shape and have a first and a second cylinder head, respectively. The cylinders of the first bank are displaced from the cylinders of the second bank in the axial direction of the camshaft. A first camshaft having first valve-operating cams for the first cylinders is provided on the first cylinder head of the first cylinders. A second camshaft having second valve-operating cams for the second cylinders is provided on the second cylinder head of the second cylinders. The first and second camshafts are operatively connected at their one end with the associated end of the crankshaft for synchronized rotation therewith through a transmission mechanism. The first cams on the first camshaft are displaced from the second cams on the second camshaft in a manner such that the former are disposed axially more apart from the transmission mechanism than the latter. The engine auxiliary mechanism is driven by means of the first camshaft and has a drive section mounted on the first camshaft at a location between the transmission mechanism and the one of the first cams on the first camshaft nearest to the transmission mechanism.

    摘要: An exhaust gas recirculation device in which exhaust gas from the engine of a vehicle, for example, may be recirculated via two separate lines to portions of a carburetor which are upstream and downstream of a throttle valve, to permit a suitably large amount of exhaust gas to be recirculated when necessary and which includes control means which stops the flow of gas in both lines when the engine is being warmed up, and stops the flow of gas in the upstream recirculation line only when engine load, engine speed, or vehicle speed is high, or when there is a risk of icing in the carburetor, whereby the disadvantages of recirculated exhaust gas during particular engine operating conditions are avoided.

    摘要: Internal combustion engine having an intake port formed in cylinder head and first and second intake passages both connected with the intake port. The intake passages are respectively provided with throttle valves and the throttle valve in the second intake passage is opened only under a heavy load operation. The ignition timing is advanced or an additional supply of fuel is provided in the transient period wherein the throttle valve in the first intake passage has reached substantially fully open position and the throttle valve in the second intake passage has started to open so as to supplement any decrease in the engine output in this period.
