摘要： The Inventor invented a combustion control device which optimizes combustion regardless of the cetane number of a fuel of an internal combustion engine (1) by focusing on the correlation between the cetane number and specific gravity of the fuel, and correcting combustion control based on the specific gravity of the fuel. The combustion control device comprises a sensor (7, 32, 36, 37) which detects the specific gravity of the fuel, a device which adjusts a combustion-related element of the internal combustion engine (1) such as fuel injection, compression end in-cylinder temperature and an intake air swirl (15, 19, 27, 51), and a controller (21) programmed to correct a target value of the element based on the specific gravity of the fuel (S414, S424, S430), and control the adjusting device so that the corrected target value is realized (S415, S425, S430).

摘要： A device for preventing the turbo-charger from over-running, wherein an actuator is arranged in a by-pass bypassing a turbine of the turbo-charger and operates a waste gate valve. The actuator has a positive pressure chamber communicated, via a boost pipe, with an intake air passage downstream of a compressor and a negative pressure chamber communicated with a source of negative pressure via a negative pressure pipe. The negative pressure chamber is so constituted as to be supplied with a negative pressure to have a target pressure that is set relative to the atmospheric pressure.

The first and second stage compressor impellers are attached to a common shaft, and are positioned within respective compressor housing in a direction facing away from one another. A portion of the second compressor housing is formed from a compressor backplate attached to a turbocharger center housing. A scroll seal is disposed between the first and second compressor housings, and is interposed between the impellers to separate outlet air flow between each respective first and second compressor chamber.

摘要： Abstract of DisclosureMethod and arrangement for regulating the rotational speed of a crankshaft included in an internal combustion engine during a gear changing process of a gearbox connected to the internal combustion engine. The arrangement includes a compressor mounted in connection with the air inlet of the internal combustion engine. A transmission having a variable gear ratio is located between the crankshaft and a driving shaft arranged in connection with the compressor, and a control means is arranged to control the gear ratio between the crankshaft and the compressor. When changing from a higher to lower gear, the control means is arranged to control the gear ratio between crankshaft and compressor so that the gear ratio between these components is reduced, and wherein moment of inertia is transferred from compressor to crankshaft resulting in an acceleration of the crankshaft.

摘要： In an internal-combustion engine having an exhaust-gas driven supercharger (8) and having at least two exhaust-gas valves (2, 3) per cylinder, a first exhaust-gas valve (2) in each cylinder is connected to a first exhaust manifold (4), whilst a second exhaust-gas valve (3) in each cylinder is connected to a second exhaust manifold (5). The two exhaust manifolds (4, 5) lead to at least one exhaust-gas turbine in at least one turbo compressor and the first exhaust-gas valves (2) are arranged to be opened at all engine speeds, whilst the second exhaust-gas valves (3) are arranged to be opened only at higher engine speeds. The first exhaust manifold (4) has a smaller flow area than the second exhaust manifold (5). By choosing which exhaust-gas valves are to be used, the size of the flow ducts between engine and exhaust-gas turbine can easily be suited to the size of the exhaust-gas flow which is available at the time.
