    摘要: A crankchamber precompression type two-cycle internal combustion engine including cylinder assemblies of an even number consists of at least one pair of cylinder assemblies having working cycles with 180.degree. phase difference, each cylinder assembly having a stepped cylinder constituted by a minor diameter cylinder portion and a major diameter cylinder portion, a stepped piston received in the stepped cylinder and constituted by a minor diameter piston portion and a major diameter piston portion, the minor diameter and major diameter piston portions being in sliding engagement with the minor diameter and the major diameter cylinder portions of the stepped cylinder respectively to provide an annular space serving as sub-intake chamber in the major diameter portions of the cylinders, the sub-intake chambers being connected to an auxiliary scavenging nozzle oriented toward a combustion chamber of the other associated cylinder. The sub-intake chambers are connected to auxiliary carburetors set beforehand in such a manner that they form a mixture of fuel of high quality and air, and crankchambers of the cylinders are connected to main carburetors set beforehand in such a manner that they form a mixture of fuel of low quality and air. By this arrangement, the mixture of fuel of high quality and air is first ignited in the combustion chambers to produce flame surfaces in a large area to enable complete combustion of the mixture of fuel of low quality with air to be achieved.

    摘要: A gas feeding arrangement for feeding gas from an internal combustion engine cylinder chamber to a gas tank includes a feeding conduit assembly and a dedicated feeding valve. The feeding valve is adapted to assume an open condition in which it provides for gas transport in a direction from the cylinder chamber towards the gas tank, via the feeding conduit assembly. The gas feeding arrangement includes a one-way valve adapted to prevent gas transport from the gas tank to the cylinder chamber, via the feeding conduit assembly.

    摘要: A method for estimating output compressor output temperature for a two-stage turbocharger. The method includes: storing a composite relationship relating temperature ratio across a pair of compressors of the two-stage turbocharger as a function of mass flow through such pair of compressors and pressure drop across the pair of the compressors; calculating the pressure ratio equal to the pressure at an input to the first one of the pair of compressors to the pressure at the output of the second one of the pair compressor; using the composite relationship and an output of a mass flow at the input to the first one of the pair of compressors and the calculated pressure ratio to determine the temperature ratio across the pair of compressors; and calculating the estimated output temperature of the second one of the pair of compressors by multiplying the determined temperature ratio across the pair of compressors by a temperature at the input of the first one of the pair of compressors.
