Abstract: A power unit including an internal combustion engine with a crankshaft and a power transmission system. The power transmission system being equipped with a belt-type continuously variable transmission having a drive shaft and a driven shaft. The belt-type continuously variable transmission being disposed below the axis of the crankshaft wherein the torque from the crankshaft is transmitted to the drive shaft for rotating the crankshaft and the drive shaft rotate in opposite directions. An output shaft, linked and interlocked with the driven shaft via a gear transmission system, is disposed above the continuously variable transmission. A gear transmission mechanism includes a single idle shaft, which has an axis parallel to the crankshaft, and being arranged between the driven shaft and the output shaft for rotating the driven shaft and the output shaft in the same direction.

Abstract: A system for detecting a reduction in engine coolant flow rate is provided. The system includes a device configured to monitor at least one parameter associated with an engine, and a device configured to measure actual engine air intake manifold temperature. The system further includes a controller configured to determine a theoretical engine air intake manifold temperature based on the at least one monitored parameter, compare the theoretical engine air intake manifold temperature with the actual measured engine air intake manifold temperature, and generate a signal indicative of engine coolant flow rate.

Abstract: An engine driven by high-pressure gas comprises: a high-pressure gas tank (7) for storing high-pressure gas; a piston (3) displaced when pressure is given from the high-pressure gas tank (7) to the piston (3), the piston (3) composing an expansion chamber (4) in which the high-pressure gas is expanded; and a crank shaft for converting a displacement of the piston (3) into a rotary motion, and fuel is burnt in the expansion chamber (4) when a volume of the expansion chamber (4) is expanded by the high-pressure gas supplied into the expansion chamber (4). Due to the foregoing, the piston (3) is displaced mainly by the pressure of high-pressure gas in the same manner as that of starting the engine, and the combustion of fuel is mainly used to prevent the temperature of gas in the expansion chamber (4) from being decreased.

Abstract: A pollution control method and related devices for cyclical internal combustion engines having a separate combustion chamber (1), wherein the compression chamber, the combustion chamber (1) and the expansion chamber (16) consist of three separate and entirely self-contained portions. During low-power operation, e.g. in urban traffic, the fuel injector (6) is no longer controlled during filling of the combustion chamber, whereby the combustion chamber is filled with high-temperature pure compressed air at each cycle. A small amount of additional air from an outer tank (23) for storing highly pressurized air at room temperature is fed into the combustion chamber substantially after the intake of compressed air from the engine compressor, and heated as it contacts the hot compressed air already present in the combustion chamber (1), whereafter it expands and increases the starting pressure to enable effective work to be produced during expansion.

Abstract: A method for extracting oxygen from a fluid environment, which comprises the steps of (1) contacting a first fluid environment containing oxygen with a first surface of a first oxygen permeable membrane having a first and a second surface, wherein the membrane separates the environment from an interior space of a closed container, (2) transporting a carrier fluid into contact with the second surface of the membrane, wherein the carrier fluid is confined in the closed container and the carrier fluid contains a binding-state oxygen carrier, whereby oxygen which diffuses through the membrane binds to the carrier to give a bound oxygen complex, (3) transporting the carrier fluid containing the bound oxygen complex to a first electrode compartment of an electrochemical cell which forms a second portion of the closed container, (4) electrochemically modifying the binding-state oxygen carrier to an oxidation state having less binding affinity for oxygen, thereby releasing free oxygen into the carrier fluid and produ

Abstract: An engine which utilizes gas and compressed air to provide propulsive force. A compressor and a turbo are connected to the engine to provide compressed air for driving the engine to either supplement or replace the gas.
