Problems solved by technology

From the above various methods, it can be seen that the main disadvantage is that the closed cylinders have not been processed for decompression and resistance reduction, and become the new load of the engine, thus consuming part of the effective power.
It is also because of this that it cannot be popularized on high-pressure ratio diesel engines and large-displacement internal combustion engines.

example 1

[0011] The engine adopts the overhead camshaft swing arm valve mechanism, and a decompression rocker arm 2 is newly added on each cam 1 of the part of the cylinder that needs to be closed, and one end of the decompression rocker arm 2 is pressed against the cam 1 opposite the swing arm 3 The other end of the decompression rocker arm 2 is pressed on the swing arm 3 above the valve stem, and the decompression rocker arm shaft is installed on the U-shaped bracket 4 between the camshaft and the valve. In the U-shaped groove 5 that can move up and down therein, its lifting is controlled with a hydraulic push rod 6 . When the decompression rocker arm 2 shaft was in the lifting state, the decompression rocker arm 2 was separated from the cam 1 and the swing arm 3, that is, the decompression rear rocker arm 2 did not work, and the engine was in a normal working state. When the engine is light-loaded or empty-loaded, first cut off the fuel or the mixed gas and then switch to the exhaus...

example 2

[0014] The engine adopts a bathtub-shaped combustion chamber, and the combustion chamber to be closed is rotated at a certain angle with the intake valve as the axis, so that the exhaust valve is placed outside the combustion chamber, and the exhaust valve seat is slightly lifted to form a shallow pit. Connected with the combustion chamber, add a decompression valve 7 in the combustion chamber, the decompression valve 7 is controlled by a hydraulic push rod or a pneumatic push rod, and is linked with the oil cut-off switch or the mixed gas switch; the air passage of the decompression valve is connected with the The exhaust duct is connected. When the cylinder is working normally, the decompression valve 7 is closed; when the cylinder needs to be closed under light load or no load, while cutting off the supply of fuel, air or mixed gas, control the hydraulic push rod to press down the decompression valve 7 and open it for a long time , At this time, the closed cylinder communic...

Abstract

The newly invented engine monitors the closing of the valves, ensuring the opening of some valves in each stroke, eliminating pressures contained in the cylinder, and reducing the running resistance. While improving the loading rate, this engine is more efficient in fuel consumption, more environment-friendly, and it is highly possible to be applied in diesel engines that have high compression rate. To start with the cylinder closed, it can improve the initial speed and favor the chance of starting with low temperature.

Description

technical field [0001] The invention relates to an engine, in particular to a decompression cylinder closed fuel-saving engine. Background technique [0002] The reciprocating piston internal combustion engine is widely used in the current automobile engine, and its power configuration is designed to enable the automobile to have good dynamic performance and certain glass climbing ability when it is fully loaded, and has a large reserve power. When the car is fully loaded on a flat road, it runs at a normal speed, and the load rate of the engine is only 20-50%. The optimal load rate of the engine is 80-90%, and the specific fuel consumption of the engine will increase significantly when it is partly loaded. Today's automobile engines work under partial load conditions most of the time, wasting a lot of energy and polluting our environment. In order to increase the load rate of the engine and reduce energy consumption. People have adopted the closed-cylinder working method...
