    • An engine has a geometric compression ratio of higher than 12, and includes an exhaust manifold, a variable exhaust valve timing mechanism, an ignition timing controller, and an effective compression ratio adjuster. The exhaust manifold has a plurality of branched exhaust passages connected to the respective exhaust ports of the individual cylinders; a plurality of first collector segments each of which joins the branched exhaust passages for the cylinders which are not adjacent in the exhaust order sequence; a plurality of middle exhaust passages connected to the downstream of the first collector segments, respectively; and a second collector segment that joins the middle exhaust passages. In at least low and middle speed ranges in a high load region of the engine, the effective compression ratio is set to have a value larger than 10 and the ignition timing is retarded, and the valve opening time of the exhaust valve is changed according to the engine speed so that a predetermined amount of a valve overlap period is ensured and that negative pressure waves from exhaust pressure pulses reach an exhaust port during the valve overlap period in a plurality of engine speed ranges. This effectively reduces knocking in low and middle speed ranges in a high load region of the engine while achieving high torque by keeping the compression ratio high.
