    Abstract: In an internal combustion engine, a thermostat valve for changing over between coolant circulation through a radiator-routing passage to coolant circulation through a bypass passage, is provided with a first valve for opening and closing the radiator-routing passage, and a second valve for opening and closing the bypass passage. The first and second valves and are operable concurrently. A cylinder coolant jacket around cylinder bores of a cylinder portion is partitioned into two in a cylinder axis direction to thereby form a main cylinder coolant jacket on a side of a cylinder head portion and a sub-cylinder coolant jacket on a side of a crankcase portion. The bypass passage is formed partly by the sub-cylinder coolant jacket. The above arrangement expedites warming-up during the engine start and achieves favorable appearance by a simplified structure.

    Abstract: A fixture assembly includes a primary gage member, camshaft gages, a crankshaft gage and an engine gage, all of which have planar datum surfaces that are each dimensionally located relative to the primary gage member planar datum surface. The engine gage includes an engine datum surface, and is sized and shaped to receive, support and dimensionally locate the engine. An engine block datum surface is configured to be positioned on the engine datum surface thereby locating the engine relative to the primary gage member datum surface. The primary, first, second and engine datum surfaces are fixed in a parallel relationship to each other so as to form a parallel alignment system such that when the fixture assembly datum surfaces engage and form parallel alignment with the corresponding engine datum surfaces, the camshafts and crankshaft are angularly located in a predetermined angular orientation for proper timing of the engine assembly.

    Abstract: A valve lifter with a variable lift mechanism is required to be deployed at a predetermined angle with respect to a cam unit, and the present invention is intended to achieve this requirement with a simple configuration without too much processing such as a fitting of the conventional longitudinal groove and a pin.A cam sliding contact surface of a valve lifter on which a high lift cam and a low lift cam slides is formed to be a smooth inclined surface and a cam slide starting point is lower than a cam slide terminating point, thereby establishing an elevation difference between the cam slide starting point and the cam slide terminating point. As a result, since the high lift cam and the low lift cam always move uphill on the cam sliding contact surface, namely, from the low cam slide starting point toward the high cam terminating point along the slope of the cam sliding contact surface, the valve lifter is not subjected to a force around the reciprocating axis from the cam and therefore, the direction of the valve lifter is maintained constant.

    Abstract: A device for ascertaining a camshaft position and a phase of an internal-combustion engine having multiple cylinders, including a first position sensor wheel having multiple teeth on its circumference and rotatably and fixedly connected to an engine camshaft; a first position sensor for detecting a tooth flank position of the first wheel; a transmission connecting the camshaft to a crankshaft; a second position sensor wheel having at least one tooth on its circumference and being connected to the transmission so that it is synchronously driven with the camshaft, and a second position sensor for detecting a tooth flank position of the second wheel. For ascertaining a camshaft position and a phase of an engine with this device, a camshaft position is assigned to a position of a tooth flank of the first wheel and a phase of the engine is assigned to a tooth flank position of the second wheel.
