摘要： #7 cylinder shares an exhaust manifold with #1 cylinder and is fired a predetermined firing interval after #1 cylinder. An exhaust cam shaft has a first cam for driving the exhaust cams of #1 cylinder and a second cam for driving the exhaust cams of #7 cylinder. A valve overlap period of #1 cylinder during its shift from an exhaust stroke to an intake stroke overlaps a time period during which the exhaust valves of the second cylinder are open in #7 cylinder while it is shifting from a power stroke to an exhaust stroke. The nose of the second cam is located farther in a retard direction than a position that is away in the retard direction from the nose of the first cam by an angle corresponding to the predetermined firing interval between the first and second cylinders.

摘要： This invention concerns a turbo-charged engine with EGR comprising an EGR passage connecting an exhaust passage upstream of a turbine of a turbocharger and an intake passage downstream of a compressor to each other for returning some of exhaust gas in the exhaust passage to the intake passage, and an EGR valve provided in the EGR passage for adjusting a passage area of the EGR passage. Capacity of the turbine is set such that in a high speed and high load region of the engine operating state, if the exhaust gas is supplied to the turbine with the EGR valve closed, the turbocharger overruns beyond a maximum speed limit, and if the EGR valve is opened to return some of the exhaust gas to the intake passage, the turbocharger rotates at less speed than the maximum speed limit. EGR can be performed in the high speed and high load region of the engine operating state without reducing power output and worsening fuel consumption.

摘要： A turbo charger system (32) for a diesel engine (1) with a simple structure, but improved in output, torque and fuel consumption rate. A high-stage turbine (3) and low-stage turbine (4) are provided in series on an exhaust gas line (2) of the engine (1). A high-stage compressor (6), which is connected to the high-stage turbine (3), and a low-stage compressor (7), which is connected to the low-stage turbine (4), are provided in series on an intake air line (5) of the engine (1). A bypass line (20) with a valve (21) is provided over the high-stage turbine (3). The bypass valve (21) is completely or substantially completely closed until the engine (1) reaches its maximum torque point (14) so as to raise a supercharging pressure. From the maximum torque point (14) to the maximum output point (15), the bypass valve (21) is gradually opened to adjust the supercharging pressure. The bypass valve is completely or substantially completely opened at the maximum output point (15) to suppress the supercharging pressure.
