Abstract
The utility model relates to a common fire box double-piston differential step type gas engine, characterized in that, the double-piston applies work in the same fire box, and the double-piston operates in differential step. The moment to generate the largest compressive force is at the one half of the angle difference after the forthgoer is at the upper solstitial point and before the posterior is at the upper solstitial point, which avoids the larger compressive force generated when reaching the upper solstitial point simultaneously and avoids the machine parts suffering more moment, so the compression ratio at the other moment is enlarged and the mechanical efficiency is advanced.
Description
Technical field
The utility model relates to stroke piston combustion engine.
Background technique
Existing stroke piston combustion engine is all single piston single combustion chamber acting, and the pressure of solstice is big more in its compression in the compression work stroke, and working efficiency is high more.Nowadays this technology has liked to be limited to the strength of material, and on the current material basis, increasing compression ratio is to be difficult to realize.
Summary of the invention
The purpose of this utility model is to provide a kind of combustion chamber shared double-piston difference step operation type internal-combustion engine.
The technical solution of the utility model is: motor described in the utility model comprises cylinder body, firing chamber, piston, connecting rod, crank.Characteristics are that the connecting rod of two-piston is located at not on the crank of same axis.
V-shaped being distributed on the different axis of two cranks of above-mentioned motor.
Because two cranks in the utility model are not on same axis, two pistons can not be arrived simultaneously to point, so just make the compression ratio of other constantly single relatively piston time of running become big relatively, the pressure maximum of last solstice remains unchanged, thereby realize the reduction of fuel consumption, improve mechanical efficiency.
Description of drawings
Fig. 1 is that piston is at the maximum schematic representation constantly of compressive force.
Fig. 2 is that double-piston exists operation angle at maximum two-piston constantly of compressive force and crank
