Abstract

The invention discloses a method for improving engine efficiency and an engine matched with the method, including an engine frame, a power transmission system, a spark plug, a fuel injector and an intake and exhaust system, and the feature is that the power transmission system includes a crank connecting rod mechanism and Power acceleration compensation device; the crank-link mechanism includes a body group, a piston connecting rod group and a crankshaft flywheel group, and the body group includes a crankcase, a cylinder block, and a cylinder head connected with the cylinder block; the power acceleration compensation device includes The acceleration compensation piston and the acceleration compensation piston rod are arranged in the same cylinder body, and the acceleration compensation transmission mechanism is connected between the acceleration compensation piston rod and the crankshaft, and the crankshaft drives the acceleration compensation piston to move in the compensation space inside the cylinder body through the acceleration compensation transmission mechanism. The invention utilizes the power acceleration compensation device to adjust the angle between the crankshaft and the cylinder to re-ignite, increase the power of the engine, reduce the idle speed and dynamic load speed of the engine, and realize the purpose of energy saving.

Description

technical field [0001] The invention relates to the technical field of engines, and more specifically relates to a method capable of improving engine efficiency and a corresponding high-efficiency and energy-saving engine. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy. It has experienced three development stages: steam engine, external combustion engine and internal combustion engine. There are many types of internal combustion engines, and common gasoline engines and diesel engines are typical internal combustion engines. However, due to the different properties of gasoline and diesel, there are differences in the working principle and structure of the engine. [0003] 1. The working principle of a gasoline engine is to mix air and gasoline in a certain proportion to form a good mixture, which is sucked into the cylinder during the intake stroke, and the mixture is compressed and ignited to generate heat ...

AI Technical Summary

Problems solved by technology

To solve this problem, the flywheel must have a large enough moment of inertia, which in turn leads to an increase in overall engine mass and size

The use of multi-cylinder engines can make up for the above shortcomings, but at the same time, there are also problems such as complex structure, difficult process, and high technical requirements.

[0021] Moreover, the current common internal combustion engine still has the problem of low energy efficiency, which is manifested as:

[0022] 1. The piston of the engine reaches the top dead center, and when the compression ratio reaches a certain point, it is ignited or compression-ignited (the diesel engine adopts compression-ignition technology), not only the energy in the initial combustion period is not effectively utilized, but also the cylinder pressure increases, which affects the service life of the engine;

[0023] 2. Due to the difference in fuel quality, the optimal compression ratio of the fuel in the cylinder is different. If a vehicle that requires high-grade gasoline accidentally uses low-grade oil, it may cause detonation in advance and cause damage to the engine.
