Embodiment Construction

[0010] The number of cylinders and the corresponding injection devices of multi-cylinder engines of non-hybrid vehicles are divided into two groups, Group A and Group B. Each group of oil cylinders and injection devices are evenly distributed along the crankshaft axis of the engine, and the number of Group A is not less than that of Group B. Quantity, set up a set of independent air intake systems for Group A and Group B respectively, the number of bronchus connected to the intake manifold of Group A and Group B is corresponding to the number of oil cylinders in Group A and Group B; for an additional set of intake air The detection quantity and control quantity generated by the system expand the electronic control system; offline detection of the relationship between the throttle opening and fuel injection quantity of group A and the engine spindle speed when the fuel consumption rate of group A cylinder is the smallest when the cylinder of group B is empty Relationship lines. ...

Abstract

The invention relates to a high-efficiency engine and a control method. The high-efficiency engine and the control method aim at the control problem of main shaft rotating speed of an engine when theautomobile engine adopts the engine rotating speed to determine the opening degree of a throttle valve and oil injection according to the principle of minimum fuel consumption rate so as to improve the fuel efficiency of the engine. According to the high-efficiency engine, an oil cylinder is divided into two groups, namely group A and group B, each group is provided with an independent air inlet system, and the air quantity of the B group is controlled by a traditional accelerator pedal mode so as to achieve main shaft rotating speed control; and the group A adopts the rotation speed of the engine to determine the opening degree of a throttle valve and fuel injection quantity according to the minimum principle of the fuel consumption rate, so that the fuel consumption rate of the oil cylinder in the group A is always optimal, and the overall fuel efficiency of the engine is improved.

Description

technical field [0001] The invention relates to an engine and a control method, in particular to an engine and a control method with high fuel efficiency. Background technique [0002] Oil depletion and environmental pollution have become the most urgent problems facing the world's automobile industry and even all mankind. How to make the engine work in the best working condition has attracted more and more attention from governments. [0003] Chinese Patent Publication No. CN 107364441 A, published on November 21, 2017, the title of the invention is a method for controlling the minimum fuel consumption rate of an extended-range electric vehicle. The method of the minimum power state has the disadvantage that the engine speed needs to be controlled by the resistance torque provided by the external power source of the engine. Contents of the invention [0004] Technical problem to be solved [0005] The technical problem to be solved by the present invention is to improve...
