Problems solved by technology

Because this kind of engine can work under variable working conditions, its thermal efficiency is extremely high, and its output power is large, so it is widely used in the military, such as tanks, warships and other ordnance that require high-power output engines. The structure is too complex to be eliminated

Embodiment Construction

[0011] Accompanying drawing 1 is the relative structure schematic diagram of the reciprocating engine with adjustable compression ratio and high supercharging two-stroke opposed piston arrangement. In the figure, a group of connecting rods, i.e. exhaust large connecting rod 3 and intake large connecting rod 4, are installed on the crankshaft 2 connected with flywheel 1. The exhaust lever 5 is connected with the large exhaust connecting rod 3; the intake lever 6 is connected with the large intake connecting rod 4. The cylinder 11 is equipped with an exhaust end piston 7 and an intake end piston 8, the exhaust end piston 7 is connected with the exhaust lever 5 through the exhaust small connecting rod 9; The lever 6 is connected. The exhaust eccentric shaft 12 is connected with the exhaust spoke 14; the intake eccentric shaft 13 is connected with the intake spoke 15. The exhaust end worm gear 16 on the exhaust spoke 14 and the intake end worm gear 17 on the intake spoke 15 mesh...

Abstract

The double-piston DC scavenging engine is characterized by that in same cylinder interior it contains two opposed pistons which can be reciprocated, a crankshaft connected with two opposed pistons, agroup of two piston rods, a group of two pitman rockerarms, a group of two connecting rods mounted on a crankshaft, two groups of eccentric shaft main shafts and eccentric shaft rockerarms which are completely and symmetrically arranged and two groups of wormwheels and worms which are symmetrically arranged and connected with a controllable motor. Said engine can be made up by using ceramic material, and can use various alcohol fuels and vegetable oil fuels, also can use regenerated clean fuel.

Description

technical field [0001] The invention relates to a double-piston direct-flow scavenging engine, in particular to a double-piston direct-flow scavenging engine with opposed pistons. Background technique [0002] A double-piston direct-flow scavenging engine once used in the prior art has a technical proposal that there are two pistons in the same cylinder, the pistons are arranged in opposite directions in the cylinder, and are arranged in a straight line, and each of the two pistons has a The connecting rod adopts two crankshafts. This opposed piston arranges double-piston DC scavenging engine without intake and exhaust valves, and also without intake and exhaust valve springs. Because this kind of engine can work under variable working conditions, its thermal efficiency is extremely high, and its output power is large, so it is widely used in the military, such as tanks, warships and other ordnance that require high-power output engines. The structure was too complex and w...
