At a low part load, and at idling of a vehicle machinery it is difficult to obtain a good fuel economy and acceptable emission rates. The amount of work for driving the compressor and the auxiliary apparatuses is considerable in a gas turbine, and in view of the conditions mentioned the combustor of the gas turbine is provided with two burners, of which one is dimensioned for a fuel quantity which merely corresponds to 'spare-flame' operation. An auxiliary motor means is included in the machinery and keeps, together with the 'spare-flame' operation. An auxiliary motor means is included in the machinery and keeps, together with the 'spare-flame' burner, the main rotor of the gas turbine running at idling and part-load. The auxiliary motor may be an electric motor, a pressure fluid motor, or a combustion engine. The compressor is provided with means for throttling the flow of air, and a control device operates this throttling means so it is effective during 'spare-flame' operation.

Swing starter (1) comprising a straight target rod (2) and a curved rod (3)interconnected by a web (4). The curved rod has a radius of curvature of about 1.55 m and a length of about 0.6 m. The front portion (5) comprises a convex mirror (6) having a indicator line (7) parallel with the target line. The swing starter is placed on the ground having a pin (9) thereof extending down into the ground. The pin allows the swing starter to be pivoted under friction around an axis parallel to the target line. The golfer places himself beside the swing starter opposite the front end (5) thereof. The swing starter is pivoted until a convex mirror (6) positioned at the front end of the curved rod indicates the correct swing plane has been achieved by viewing the shoulder portion of the golfer at a line (7) of the mirror. The upper surface of the curved rod may be provided with a color, e.g., red, differing from the color, e.g. white, of the remaining portion of the device. In an alternate embodiment, the curved rod may be clipped onto and supported by the shaft of a golf club which is positioned on the golfing surface and serves as the target rod.

The turbocharging plant of an internal combustion engine includes two turbines connected in series, of which one drives the compressor and the other transfer its output to the engine mechanically. The turbines and the compressor are mounted at the same side of the engine. The turbines can be designed to handle the gas in a radially inwards directed flow, the downstream turbine being mounted at a lower level than the upstream one, and receiving the gas by way of a double volute device. A third turbine desinged to handle the gas in a radially outwards directed flow may be interposed between the two first mentioned turbines.

Turbocharging device for an internal combustion engine

An internal combustion engine for vehicle propulsion has a number of cylinders arranged in two parallel planes and connected to two crank shafts within a common engine block. A selectively operable clutch is fitted at at least one of the crank shafts, and a gearing coordinates the output from the two crank shafts. A coupling is provided between the gearing and the output shaft of the engine plant.

A vehicle power plant comprising a number of engine working cylinders arranged in two groups with different numbers of cylinders and/or with different power outputs, the parts being individually connectable to a common power take-off shaft by a continuously variable belt transmission. A gearing, including a reverse step, is mounted with its axes of rotation parallel to the crank shafts of the engines and connects the belt transmission to the vehicle output shaft. This vehicle power plant produces good fuel economy, high top power output, low exhaust emissions, and good acceleration capacity.

Outlet and inlet conduits of an internal combustion engine are united in, and carry a housing enclosing a rotor spool having one turbine and one compressor wheel. A cavity in the housing, the longitudinal axis of which is substantially parallel to a middle plane through the row of engine cylinders is adapted to receive the casing of the turbocharger, and may be designed in such a manner that the casing may be slid into the housing in the axial directions, without the housing having to be removed from the engine. Alternatively, the outlet and the inlet conduits may each, per se, be collected and form one half of the housing. The halves are brought together over the rotor spool, from both ends thereof. Resilient sealing members are preferably fitted between the two halves of the housing. A second exhaust gas turbine may be connected to the exhaust conduit from the supercharger, and may be adapted to drive at the power take-off shaft of the engine, or to drive some auxiliary.

In order to improve the fuel economy of a vehicle engine, its cylinders are divided into two groups, which are operable independently of each other. The fuel system is adapted to supply either, or both groups with fuel. The crank shaft of one cylinder group is connectable to the power take-off shaft by means of conventional transmission and clutch means, while the crank shaft of the other cylinder group is connectable to the power take-off shaft by way of a transmission arrangement running in parallel to the row of cylinders, and comprising a shaft. The auxiliaries of the engine are mounted at the end of the engine remote from the power take-off shaft, and can be driven from either group of cylinders by way of the transmission arrangement.
