A secondary expansion mixed stroke explosive motor

Abstract

The invention provides a secondary expansion mixed stroke explosive motor which is composed of a crankpin, a connecting bar, a piston, a cylinder, a valve, a spark plug, a gas line, an inlet (outlet) pipe, an exhaust main and the related well-known parts of explosive motor (as for well-known parts of explosive motor, no extra statement is needed here). The number of the motor is 3n (n is equal to 1,2,3...); in other words, every three cylinders is regarded as one group; the cylinder in middle is fuel gas secondary expansion two-stroke-cycle cylinder; the cylinders on the two sides are gas mixture ignition first expansion four-stroke-cycle cylinder. The cylinder in the middle is provided with two gas lines and valves from the cylinders on the two sides, which is also provided with an exhaust manifold and valve and has no spark plug. The cylinders on the two sides are respectively provided with an inlet manifold (for mixed gas) and valve, an exhaust manifold and valve, a gas line connected with the cylinder in the middle and a valve, and a spark plug. The three cylinders are respectively provided with one piston and all the pistons are connected by a connecting bar and a crankpin; the included angle between the crankpin of the cylinder in the middle and the crankpin of the cylinders on the two sides in the same angel is from 0 to 180 degree. In the normal working condition of the invention, for the two cylinders on the two sides in the three cylinders, one cylinder is operated in the following process, entering air-compressing-igniting(once)expanding-fuel gas secondary expanding-exhausting-and the other cylinder is operated in the following process, (once) expanding-fuel gas secondary expanding-exhausting-entering air-compressing; the working substance can be recycled in the four stroke cycles, and at the same time, the cylinder in the middle is operated in the following process.

Description

technical field [0001] The invention relates to an engine device, in particular to a secondary expansion mixed stroke internal combustion engine. Background technique [0002] The disadvantage of conventional cycle internal combustion engines is that the expansion of the gas cannot be carried out to the end, that is, it is suddenly interrupted with the opening of the exhaust valve, so that the thermal energy of the gas cannot be expanded enough to convert into mechanical work. In this way, not only is energy seriously wasted (exhaust heat loss: 33% of the U.S. Environmental Protection Agency’s test data on typical vehicle energy distribution), and thermal efficiency is reduced. It is discharged from the exhaust pipe at high speed, causing strong disturbance and noise, polluting the environment and increasing the cost of exhaust purification. [0003] In the past, someone tried to lead out this kind of gas for secondary full expansion, but due to the complexity of the mechan...
