Horizontally opposed engine

Abstract

The invention discloses a horizontally opposed engine. Pistons are slidably arranged in a cylinder body. The pistons are connected with bent axles through connecting rods. A first piston and a second piston are arranged relatively in the cylinder body. The first piston and the second piston are connected with the bent axles through a first connecting rod and a second connecting rod correspondingly. Because the two groups of pistons of bent axles are arranged on the two sides of the cylinder body, moment of force produced by two groups of pistons mutually opposed is mutually counteracted, vibration produced when the engine works is reduced greatly, and the operation can be more smooth and steady. Because the fact that two groups of pistons are matched mutually in the same air cylinder to work oppositely is adopted by the horizontally opposed engine, the effective stress working area of the pistons is twice that of the original normal single piston, so that under the same oil fueling condition, the torque power of the horizontally opposed engine is twice that of a single piston of a normal single bent axles. Because the vibration is reduced greatly, the compression ratio can be improved greatly, so that the torque, power and fuel economy of the engine all are promoted greatly, and emission of harmful gas is reduced.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a horizontal thrust engine. Background technique [0002] Ordinary in-line engine pistons move up and down, or V-arrangement engine pistons move at a certain angle. Both ordinary in-line engines and V-arrangement engines have the following problems: [0003] 1. The center of gravity of the whole vehicle is high, the driving stability of the vehicle is poor, and the vehicle is not very agile. The higher the center of gravity, the higher the probability of vehicle rollover; [0004] Second, the more important thing is that the torque generated between two adjacent pistons cannot be offset, which makes the engine noise more likely to be generated during the driving of the vehicle; [0005] 3. In an in-line engine, in order to balance the connecting rod journal, a balance weight needs to be set on the other side of the main journal of the crankshaft, which increases the weight of th...

Problems solved by technology

[0008] The purpose of the present invention is to provide a horizontal offset engine to solve the problems that the torque produced by the two pistons relative to the existing engine cannot be offset, the engine vibrates greatly, the operation is not stable, the fuel efficiency is low and the harmful gas emission is large.
