    摘要： The invention is intended to provide good emission-cleaning performance by use of a three-way catalyst alone, without the need for a lean NOx catalyst, while ensuring a fuel economy improvement effect of lean burn operation, and to improve fuel economy up to high-load operating ranges while maintaining desired engine output performance by use of a supercharger. In a pair of preceding and following cylinders whose exhaust and intake strokes overlap each other, intake air supplied to the preceding cylinder (2A, 2D) is supercharged by a turbocharger (23) to produce combustion at a “lean” air-fuel ratio in the preceding cylinder (2A, 2D), and burned gas discharged from the preceding cylinder (2A, 2D) is introduced into the following cylinder (2B, 2C) through an intercylinder gas channel (22). Combustion in the following cylinder (2B, 2C) is made at an air-fuel ratio equal to or smaller than the stoichiometric air-fuel ratio by supplying fuel to the burned gas of a “lean” air-fuel ratio introduced from the preceding cylinder (2A, 2D), and gas discharged from the following cylinder (2B, 2C) is led to an exhaust passage (20) provided with a three-way catalyst (30).

    摘要： A spark-ignition gasoline engine having at least a spark plug, the engine including an engine body having a geometrical compression ratio set at 14 or more, and an intake valve and an exhaust valve provided, respectively, in intake and exhaust ports connected to each of a plurality of cylinders of the engine body. The intake and exhaust valves are adapted to open and close corresponding respective ones of the intake and exhaust ports. The engine further includes an operation-state detector adapted to detect an operation state of the engine body and a control system adapted, based on detection of the operation-state detector, to perform at least an adjustment control of an ignition timing of the spark plug, the control system being operable, when an engine operation zone is a high-load operation zone including a wide open throttle region within at least a low speed range, to retard the ignition timing to a point within a predetermined stroke range just after a top dead center of a compression stroke.

    摘要： There are provided a radiator passage, a thermostat to open and close the radiator passage according to an engine temperature, a heater passage, a flow adjusting device to adjust a flow amount of the coolant that flows in the water jacket according to the engine temperature at an engine start. The flow adjusting device is configured so as to adjust the flow amount of the coolant flowing in the water jacket to be a normal amount when the engine temperature is in an extremely-cold condition, to be zero or smaller than the normal amount when the engine is in a mild-cold condition, and to be the normal amount when the engine is in a warm condition. The heater passage is in opened sate at least when the engine is in the extremely-cold condition.
