Problems solved by technology

[0004] However, because the fuel needs to be upgraded in one rich-burn cylinder first, and then the upgraded fuel can be burned in multiple lean-burn cylinders for power output, the upgrading process will cause insufficient power torque of the engine, which in turn will affect the performance of the engine. performance

Abstract

The invention provides an engine, a control method of the engine and a vehicle. The engine comprises a cylinder body, an oil supply assembly, a gas supply assembly and a waste gas circulation assembly. The cylinder body comprises a compression ignition cylinder and an ignition cylinder which are arranged in parallel; and the oil supply assembly is connected with the compression ignition cylinder and can inject fuel oil into the compression ignition cylinder. The gas supply assembly is connected with the compression ignition cylinder and the ignition cylinder at the same time and can convey gas into the compression ignition cylinder and the ignition cylinder. One end of the waste gas circulation assembly is connected with the compression ignition cylinder, the other end of the waste gas circulation assembly is connected with the gas supply assembly, waste gas generated by the compression ignition cylinder can be conveyed into the gas supply assembly, insufficient power torque of the engine in the fuel oil modification process is avoided, and then the performance of the engine is improved.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular, to an engine, an engine control method, an engine control device, an engine control device, a readable storage medium and a vehicle. Background technique [0002] At present, natural gas is a clean energy with a large reserve in the world. When it is used in natural gas engines, the spark plug ignition mode has been widely used, but this type of engine has the problem of high emissions of nitrogen oxides. [0003] In the related technology, in order to solve the problem of high nitrogen oxide emissions, multiple cylinders of the engine are divided into a rich-burn cylinder and a plurality of lean-burn cylinders, and high cetane number fuel is injected into the rich-gas cylinders to ignite natural gas Rich-burned mixed gas with air, natural gas is rich-burned to generate modified mixed gas, and then the modified mixed gas is mixed with air and then passed into the lean gas c...
