Abstract

The utility model provides an air inlet valve control mechanism of a closing cylinder in a multi-cylinder engine cylinder-stopping oil-saving system. The air inlet valve control mechanism comprises an air valve rocking arm and a cylinder cover which correspond to the closing cylinder. A sliding block is arranged above the air valve rocking arm. The sliding block is supported on the lower end face of the cylinder cover in a sliding mode and can slide left and right along the length of the air valve rocking arm. The left end of the sliding block is provided with a downward protrusion. An electromagnet drive device drives the sliding block to move right and a spring arranged in the electromagnet drive device drives the sliding block to move left to reset. When the air valve rocking arm swings to enable the air valve to be completely started, the sliding block moves left so that the protrusion at the left end of the sliding block can right abut against an air valve end of the air valve rocking arm of the lowest point. To reduce loss of a non-working pump, when the air valve rocking arm swings to enable the air valve to be completely started, the sliding block slides to the left and enables the protrusion at the left end of the sliding block to right abut against the air valve end of the air valve rocking arm of the lowest point, so normal opening state of the closed air inlet valve of the cylinder is achieved.

Description

一种多缸发动机停缸节油系统中关闭气缸的进气门控制机构 One kind of a multi-cylinder engine cylinder deactivation system fuel cutoff cylinder intake valve control mechanism

[0001] 技术领域 [0001] Technical Field

[0002] 本实用新型涉及一种多缸发动机停缸节油技术,具体的涉及一种多缸发动机停缸节油系统中关闭气缸的进气门控制机构。 [0002] The present invention relates to a multi-cylinder engine fuel cylinder deactivation technology, particularly intake valve closing cylinder relates to a multi-cylinder engine fuel system of a cylinder deactivation control means.

[0003] 背景技术 [0003] BACKGROUND OF THE INVENTION

[0004] 车用多缸发动机能带来更多的动力储备,满足高速行驶、重载货物、起步急加速和爬坡的需要,但由于排量大自然会带来高油耗,对于重卡空载的时候,或者轿车在城市道路停停走走不需要强劲动力的时候,多缸发动机全缸工作就显得很浪费。 [0004] Vehicle multi-cylinder engine can bring more power reserves to meet the high speed, heavy freight, and need to start climbing hard acceleration, but because of the displacement of nature leads to higher fuel consumption, no-load for heavy trucks time, or when the car in stop-go city roads do not need a strong power, multi-cylinder engine is an all-cylinder work becomes wasteful. 因此,部分负荷时关闭一些气缸以提高发动机负荷率,是简单而有效的节油方法。 Thus, a partial load off some of the cylinders to increase engine load factor, the fuel is a simple and effective method. [0005] 凯迪拉克早在1980年便首次采用了可变气缸技术,第一辆装备该技术的车型是第二代凯迪拉克赛威。 [0005] As early as 1980, Cadillac will be the first time a variable cylinder technology, the first car equipped with the technology model is the second generation of Cadillac saiwei. 它的V6发动机在不需要大功率输出时会关闭其中两个气缸以节省燃油。 It is not required when the V6 engine power output which will close two cylinders to save fuel. 在2006年,上海通用发布的别克君越3. O V6旗舰版就带有可关闭一半气缸的DOD(Displacement On Demand)可变排量系统。 In 2006, Shanghai GM Buick LaCrosse released 3. O V6 flagship version will be shut down half of the cylinders with the DOD (Displacement On Demand) variable displacement system. 2009年奇瑞也研制出了自己DOD技术并通过国家验收,但还没有量产。 2009 Chery DOD developed its own technology and confirmed by the state, but not mass production.

[0006] 对于关闭的气缸来说,只是控制燃油不在喷入气缸内,进气门和排气门在凸轮和顶杆的作用下仍然实现有规律的启闭,就会出现泵气损失,消耗掉一部分机械能。 [0006] For closing the cylinder, the fuel control not only injected into the cylinder, the intake and exhaust valves and still achieve a regular and open and close under the action of the cam ram, pumping loss occurs, consuming off part of the mechanical energy.

[0007] 发明内容 [0007] SUMMARY OF THE INVENTION

[0008] 本实用新型要解决的技术问题是提供一种多缸发动机停缸节油系统中关闭气缸的进气门控制机构,对于关闭的气缸来说大大降低泵气损失。 [0008] The technical problem of the present invention is to solve is to provide a multi-cylinder engine cylinder deactivation system fuel cutoff cylinder intake valve control means for closing the cylinder is greatly reduced pumping loss.

[0009] 为了解决上述技术问题,本实用新型的技术方案为: [0009] To solve the above technical problem, the technical solution of the present invention is:

[0010] 一种多缸发动机停缸节油系统中关闭气缸的进气门控制机构,包括与关闭气缸所对应的气门摇臂和气缸盖,所述气门摇臂的上方设置滑块,滑块滑动支撑于气缸盖下端面并可沿气门摇臂长度方向左右滑动,滑块的左端具有向下的凸起,滑块通过电磁铁驱动装置拉动滑块向右运动并通过电磁铁驱动装置内置的弹簧使滑块向左移动复位,当气门摇臂摆动使得进气门完全开启时,滑块向左移动使得其左端凸起正好顶在处于最低点的气门摇臂气门端。 [0010] A multi-cylinder engine cylinder deactivation system above the fuel control mechanism closes the intake valve in the cylinder, comprising a cylinder and closing the corresponding valve rocker and the cylinder head, the valve rocker arm is provided as the slider slidably supported in the cylinder head and the lower end surface of the slide valve along the longitudinal direction of the left and right rocker arm, the left end of the slider has a downward projection, the slider is pulled by the electromagnet drive apparatus and slide rightward movement of the electromagnet drive apparatus built reset spring moves the slider to the left, the valve rocker arm such that when the intake valve is fully opened, such that the left slider to the left top of the valve boss exactly at the lowest point of the valve end of the rocker arm.

[0011 ] 上述多缸发动机停缸节油系统中关闭气缸的进气门控制机构,所述气门摇臂气门端上方固定有向上凸起的衬块,当气门摇臂摆动使得进气门完全开启时,滑块向左移动使得其左端凸起正好顶在衬块上。 [0011] The multi-cylinder engine fuel system of a cylinder deactivation control mechanism closes the intake valve of a cylinder, the valve end of the rocker arm above the valve is fixed to the pad upwardly convex, when the rocker arm such that the valve is fully opened inlet valve when the slider to the left so that its left end projections on the top right pad.

[0012] 为了减小非工作缸换气过程中克服进气道阻力所消耗的功和克服排气道阻力所消耗的功,即泵气损失,需使得处于关闭状态的气缸的进气门处于常开状态,当气门摇臂摆动使得进气门完全开启时,滑块向左移动使得其左端凸起正好顶在处于最低点的气门摇臂气门端,实现处于关闭状态的气缸的进气门处于常开状态。 [0012] In order to reduce the non-operating cylinders during the ventilation resistance against the power consumed by the intake and exhaust passage resistance against the power consumed, i.e., the pumping loss, so that the required intake valve of a cylinder is in the closed state normally open state, the valve rocker arm such that when the intake valve is fully opened, such that the left slider to the left in the top right projections valve rocker arm end at the lowest point of the valve, to achieve closed state the intake valve of the cylinder in a normally open state.
