Embodiment Construction

[0041] The core of the present application is to provide the method and device for starting the engine. Allowing the engine to start from a standstill reduces engine start-up wear. During the driving process of the vehicle, the engine starts to run after idling for a period of time, so as to prevent or reduce the occurrence of the vehicle oil emulsification problem. At the same time, a method for recovering kinetic energy of the vehicle is provided.

[0042] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary s...

Abstract

The invention discloses an engine starting method and device. The method comprises the steps that a user unlocks a vehicle door of a vehicle outside the vehicle; after the vehicle door is unlocked, a starting motor in an engine is started, and the starting motor drives an engine oil pump to operate and supply oil; the engine oil pump provides engine oil for the surfaces of all parts of the engine for lubrication; the user enters the vehicle to start the engine, and the engine runs at an idle speed; in the running process, when the vehicle is of a hybrid power vehicle type and the navigation function of the vehicle is not started, according to the change of the vehicle speed, the vehicle is driven by a driving motor to run, or the vehicle starts the engine to run at an idle speed, or the engine drives the vehicle to run. The engine is started in the mode, the starting abrasion of the engine is reduced when the engine of the vehicle is in the static state or the running state, and engine oil of the engine is prevented from being emulsified. And kinetic energy can be better recovered.

Description

technical field [0001] The invention relates to engine starting, in particular to engine static starting and running start, preventing and reducing the problems of engine starting wear and engine oil emulsification. Background technique [0002] After the existing vehicle is parked for a long time, engine wear is prone to occur when the engine is started. In addition, in hybrid models, the vehicle is driven by the electric motor for a long time, and the engine is prone to not running for a long time. Once the engine is started while the vehicle is running at high speed, due to the large amount of intake air, more water vapor, and lower engine temperature, the problem of oil emulsification is likely to occur. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents of the invention [0004] The purpose of this application is to provide a lubricating oil for various parts of ...
